Milk Thistle

Milk Thistle - Carduus marianum; Silybum Compositae

Citations Habitat : Throughout Europe, rare in Britain. Common In California

Collection : The mature achenes (seed heads) are cut ant stored in a warm place. After a few days, tap the heads and collect the seeds.

Part Used : The seeds.

Constituents : Flavolignans; the mixture of these is known as silymarin and composed mainly of silybin (=silibinin), with isosilybin, dihydrosilybin, silydianin, silychristin, and in some varieties at least, silandrin, silymonin, silyhermin and neosilyhermin.

Actions : Hepatic, galactogogue, demulcent, cholagogue.

Indications : For more details on this plants please refer to the section on the liver. Milk Thistle can be used to increase the secretion and flow of bile from the liver and gall-bladder. Its traditional use as a liver tonic has been supported by research showing that it contains constituents which protect liver cells from chemical damage. It is used in a whole range of liver and gall bladder conditions including hepatitis and cirrhosis. Historically this herb has been used in Europe as a liver tonic and current phytotherpy indicates its use in a whole range of liver and gall bladder conditions including hepatitis and cirrhosis. It may also have value in the treatment of chronic uterine problems. A wealth of research done in Germany is revealing exciting data about reversal of toxic liver damage as well as protection from potential hepatotoxic agents. A number of chemical components of herb are now being shown to have this protective effect on liver cells. They are all flavones and flavo-lignins, the best studied being silymarin. Silymarin has been shown to reverse the effects of highly toxic alkaloids, such phalloidine and a-amanitine from the Avenging Angel mushroom (Amanita phalloides) as well as protect liver cells from their impact. The pharmacodynamics, site and mechanism of action of silymarin are becoming well understood, providing insights into the metabolic basis of this herbs activity., an activity long known and used by medical herbalists. As its name implies, it promotes milk secretion and is perfectly safe to be used by all breast feeding mothers.

Preparations & Dosage : Infusion: pour a cup of boiling water onto l teaspoonful of the ground seeds and let infuse for l0-l5 minutes. This should be drunk three times a day. Tincture: l-2 ml three times a day.


Milk Thistle (Silymarin) a herb most commonly recommended as a liver cleanser and complementary medical treatment for hepatitis.


Astragalus

Astragalus membranaceus Leguminosae

Citations Names : Milk-vetch root, huang qi

Part Used : Root. Constituents :

Glycosides, Polysaccharides, choline, betaine, rumatakenin, b-sitosterol

Actions : Immunomodulator

Indications : Used since ancient times in Traditional Chinese Medicine, it has become an important remedy in the west since its effects upon the immune system came to light. As the power of immunological research is focussed on medicinal herbs a whole new array of effects are being discovered. The polysaccharides in Astragalus have been shown to intensify phagocytosis of reticulo-endothelial systems, stimulate pituitary-adrenal cortical activity and restore depleted red blood cell formation in bone marrow. Astragalus is also one of the herbs known to stimulate the bodies natural production of interferon. The therapeutic potential offered is very exciting. For more details please refer to pages 3-285 to 3-292. The conclusion being drawn by most western herbalists is that Astragalus is an ideal remedy for any one who might be immuno-compromised in any way. This can range from someone who easily catches colds to someone with cancer.

Preparations & Dosage : Decoction: put l teaspoonful of the root into a cup of water, bring to boil and simmer for l0-l5 minutes. This should be drunk three times a day. Tincture: take 2-4 ml of the tincture three times a day.


Astragalus: a Chinese herb that enhances the antibody reaction to foreign invaders of all types including cancer.

Ginkgo: a potent central nervous system antioxidant for the treatment of circulation disorders, memory problems, high blood pressure, depression, tinnitus and immune system disorders.


Echinacea

Echinacea spp.

Compositeae

Citations

Names : Purple Coneflower

Habitat : Throughout North American prairies, plains, and open woodlands.

Part Used : The root.

Constituents : o Echinacoside, in E. angustifolia but not E. purpurea.Research suggests that the echinacosides glycosides appear to be primary anti-microbial constituents in Echinacea. However there are many other biologically active substances present, and there is evidence that they work synergistically. The polysaccharides, for example, possess the best immune stimulating properties and are also antiviral.

o Unsaturated isobutyl amides, echinacin and others, in E. angustifolia and E. pallida.

o Polysaccharides; a heteroxylan and an arabinorhamnogalactan

o Polyacetylenes, at least 13 of which have been isolated. It has been postulated that these are artifacts formed during storage, since they are found in dried but not fresh roots of E. pallida.

o Essential oil, containing humulene, caryophyllene and its epoxide, germacrene D and methyl-p-hydroxycinnamate

o Miscellaneous; vanillin linolenic acid derivatives, a labdane derivative, alkanes and flavonoids and the alkaloids tussilagine and isotussilagine.

Note: Sesquiterpene esters which were originally identified in commercial samples of E. purpurea have since been shown to be due to the presence of an adulterant, Parthenium integrifolium L. (American Feverfew). It appears that this adulteration may be widespread in commercial samples.

Actions : Anti-microbial, immunomodulator, anti-catarrhal, alterative.

Indications : Echinacea is one of the primary remedies for helping the body rid itself of microbial infections. It is often effective against both bacterial and viral attacks, and may be used in conditions such as boils, septicaemia and similar infections. In conjunction with other herbs it may be used for any infection anywhere in the body. For example in combination with Yarrow or Bearberry it will effectively stop cystitis. It is especially useful for infections of the upper respiratory tract such as laryngitis, tonsillitis and for catarrhal conditions of the nose and sinus. In general it may be used widely and safely. The tincture or decoction may be used as a mouthwash in the treatment of pyorrhoea and gingivitis. It may be used as an external lotion to help septic sores and cuts. Much research is focussing upon this plant, providing important insights into its activity and potential uses. Glycosides from the roots have mild activity against Streptococci and Staphylococcus aureus. Echinacoside was the most active with about 6 mg being equivalent to one unit of penicillin. The tincture was able to reduce both the rate of growth and the rate of reproduction of Trichomonas vaginalis, and was found to be effective in halting the recurrence of Candida albicans infection. It seems to prevent infection and repair tissue damaged by infection, partially through inhibiting the activity of the enzyme hyaluronidase. The hyaluronidase system is a primary defense mechanism, involving connective ground substance, or hyaluronic acid, acting as a barrier against pathogenic organisms. Some pathogens activate an enzyme, hyaluronidase, which once activated destroys the integrity of the ground substance. This causes the barrier to become leaky, allowing pathogens to invade, attach themselves to exposed cells, penetrate the membrane and kill the cell. The result as an inflammatory infection. Echinacea inhibits the action of hyaluronidase by bonding with it in some way, resulting in a temporary increase in the integrity of the barrier. Fewer pathogens are able to stimulate the destruction of the ground substance. A range of constituents mediate this process, especially a complex polysaccharide called echinacin B. This anti-hyaluronidase action is involved in regeneration of connective tissue destroyed during infection and in the elimination of pathogenic organisms creating the infection. Purified polysaccharides prepared from Echinacea possess a strong activating force on the bodys macrophage-mediated defense system. These macrophages initiate the destruction of pathogens and cancer cells. Echinacea activates macrophages by itself, independent of any effect with T-cells. A tumor-inhibiting principle has been found, a oncolytic lipid-soluble hydrocarbon from the essential oil. The echinacosides glycosides appear to be the primary antibiotics, but there are many other active substances present which probably function synergistically. The polysaccharides possess the best immune stimulating properties and are also antiviral. Other constituents have been shown to possess good anti-tumor, bacteriostatic, and anesthetic activity.

This all points to the conclusion that its actions relate to immune system functioning on some level, helping deal with infections and stimulating the immune response. It activates the macrophages that destroy both cancerous cells and pathogens, increases the level of phagocytosis by raising levels of white blood cells such as the neutrophils, monocytes, eosinophils, and B lymphocytes. It also has an effect on properidin levels, indication an activation of the complement system.

Preparations & Dosage : Decoction: put 1-2 teaspoonfuls of the root in one cup of water and bring it slowly to boil. Let it simmer for 10-15 minutes. This should be drunk three times a day. Tincture: take 1-4 ml of the tincture three times a day. Echinacea is often, inappropriately, used as a daily immune support (whatever that is!). A quote from Dr. Daniel Mowreys excellent review of Echinacea in Next Generation Herbal Medicine is pertinent here:

Daily intake should be restricted to what is deemed necessary. During cold and flu season, two to four capsules per day is sufficient. In the presence of acute infection, that dosage may be increased, without danger, to more than 8 capsules. In the presence of chronic infections, such as chronic hepatitis, echinacea may be used continuously for several months. However, for the maintenance of a healthy immune system, echinacea is most wisely used periodically--a few weeks on, and a few weeks off, throughout the year. Echinacea is not a tonic in all aspects; granted that it has been observed to stabilize the production of neutrophils, such tonic action has not been observed on other immune factors, such as properdin production. In the absence of conclusive experimental findings, it is both safe and wise to assume that the constant, unremitting use of echinacea could be stressful on certain aspects of the immune system. During breaks, the immune system will adapt and increase in natural strength.


Echinacea: the most popular herb in North America used as a treatment for toothaches, bites or stings and all types of infections.


Coenzyme Q10

Coenzyme Q10 is found in every cell in the body, thus its other name, ubiquinone (from the word ubiquitous and the coenzyme quinone). Ubiquinone is a naturally-occurring substance with a molecular structure that is similar to vitamin K. Because the body must have energy available to perform even the simplest operation, Coenzyme Q10 is considered essential for the body's cells, tissues and organs.

Even though the body has the ability to produce Coenzyme Q10, deficiencies have been reported in a range

of clinical conditions.

Supplementation of the coenzyme helps one guard against a possible deficiency. Aging is considered one reason for a deficiency, since the liver loses its ability to synthesize Coenzyme Q10 as one gets older. Besides aging, poor eating habits, stress and infection affect the body's ability to provide adequate amounts of Coenzyme Q10.

Known results of using Coenzyme Q10 as an oral supplement are energy increase, improvement of heart function, prevention and cure of gum disease, a boost to the immune system and possible life extension. AIDS is a primary target for research on coenzyme Q10 because of its immense benefits to the immune system.

The greatest amount of the coenzyme (and, therefore, the greatest need for the enzyme) is contained in the heart and liver, which accounts for its positive results in the treatment of cardiovascular disease, angina pectoris, coronary disease, congestive heart failure, cardiomyopathy, hyperthyroid heart failure, mitral valve prolapse and hypertension.

Coenzyme Q10 may prove of benefit to those who are overweight because it improves the efficiency of energy production at the cellular level. It has also demonstrated excellent results in clinical trials on periodontal disease by speeding up healing time, reducing gum pockets, and improving other factors associated with gum disease.


Coenzyme Q10: an antioxidant involved in the electron transport chain needed for all energy dependent processes in the body. CoQ10 increases helper T-cells and reduces infection risk.


Liquorice

Glycyrrhiza glabra

Leguminosae

Habitat : Native to the Mediterranean region and parts of Asia, cultivated worldwide.

Collection : The roots are unearthed in the late autumn. Clean thoroughly and dry.

Part Used : Dried root.

Constituents : o Triterpenes of the oleanane type, mainly glycyrrhizin (=glycyrrhizic or glycyrrhizinic acid), and its agylcone glycyrrhetinic acid (=glycyrrhitic acid), liquiritic acid, glycyrrhetol, glabrolide, isoglabrolide, licoric acid, & phytosterols.

o Flavonoids and isoflavonoids; liquiritigenin, liquiritin, rhamnoliquiritin, neoliquiritin, licoflavonol, licoisoflavones A and B, licoisoflavanone, formononetin, glabrol, glabrone, glyzarin, kumatakenin and others.

o Coumarins; liqcoumarin, umbelliferone, herniarin glycyrin.

o Chalcones; liquiritigenin, isoliquiritigenin, neosoliquiritin, rhamnoisoliquiritin, licuraside, licochalcones A and B, echinatin and others.

o Polysaccharides, mainly glucans.

o Volatile oil, containing fenchone, linalool, furfuryl alcohol, benzaldehyde.

o Miscellaneous; starch, sugars, amino acid etc.

Actions : Expectorant, demulcent, anti-inflammatory, anti-hepatotoxic, anti-spasmodic, mild laxative.

Indications : Liquorice is a traditional herbal remedy with an ancient history and world wide usage. Modern research has shown it to have effects upon, amongst other organs, the endocrine system and liver. The triterpenes of Glycyrrhiza are metabolized in the body to molecules that have a similar structure to the adrenal cortex hormones. This is possibly the basis of the herbs anti-inflammatory action. As an anti-hepatotoxic it can be effective in the treatment of chronic hepatitis and cirrhosis, for which it is been widely used in Japan. Much of the liver orientated research has focused upon the triterpene glycyrrhizin. This inhibits hepatocyte injury caused by carbon tetrachloride, benzene hexachloride and PCB. Antibody production is enhanced by glycyrrhizin, possibly through the production of interleukin. Glycyrrhizin inhibits the growth of several DNA and RNA viruses, inactivating Herpes simplex virus particles irreversibly. It has a wide range of ises in bronchial problems such as catarrh, bronchitis and coughs in general. Liquorice is used in allopathic medicine as a treatment for peptic ulceration, a similar use to its herbal use in gastritis and ulcers. It can be used in the relief of abdominal colic.

Kings Dispensatory describes it thus: Liquorice root is emollient, demulcent and nutritive. It acts upon mucous surfaces, lessening irritation and is consequently useful in coughs, catarrhs, irritation of the urinary organs and pain of the intestines in diarrhoea. It is commonly administered in decoction, sometimes alone, at other times with the addition of other agents and which is the preferable mode of using it. As a general rule, the acrid bark should be removed previous to forming a decoction. When boiled for some time the water becomes impregnated with its acrid resin; hence, in preparing a decoction for the purpose of sweetening diet drinks or covering the taste of nauseous drugs, it should not be boiled over 5 minutes. The efficiency of the root in old bronchial affections may be due to this acrid resin. The powdered root is also employed to give the proper solidity to pills and to prevent their adhesion; the extract for imparting the proper viscidity to them. The extract, in the form of lozenge, held in the mouth until it has dissolved, is a very popular and efficient remedy in coughs and pectoral affections. An excellent troche or lozenge, very useful in ordinary cough, may be made by combining together 6 parts of refined Liquorice, 2 parts of benzoic acid, 4 parts of pulverized alum, and 1/2 a part of pulverized opium. Dissolve the Liquorice in water and evaporate to the proper consistency, then add the powders with a few drops of oil of Anise and divide it into 3 or 6-grain lozenges. The bitterness of quinine, quassia, aloes and the acrid taste of senega, guaiacum, mezereon and ammonium chloride are masked by Liquorice.

Preparations & Dosage : Decoction: put 1/2 - l teaspoonful of the root in a cup of water, bring to the boil and simmer for l0-l5 minutes. This should be drunk three times a day. Tincture: take l-3ml of the tincture three times a day.

Caution : There is a small possibility of effecting electrolyte balance with extended use of large doses of liquorice. It has an ACTH like effect causing retention of sodium thus raising BP. The whole herb has constituents that counter this but it is best to avoid Liquorice if the patient has hypertension, kidney disease or during pregnancy.


Licorice: an anti-inflammatory and anti-allergic herb used to boost energy, treat respiratory tract infections as well as female disorders, ulcers, adrenal insufficiency and congestion.


Boneset

Eupatorium perfoliatum

Compositae

Citations:

Names : Feverwort

Habitat : N. America

Collection : Boneset should be collected as soon as the flowers open in August or September.

Part Used : Dried aerial parts

Constituents : o Sesquiterpene lactones ; eupafolin, euperfolitin, eufoliatin, eufoliatorin,

euperfolide, eucannabinolide and helenalin

o Immunostimulatory polysaccharides, mainly 4-0-methylglucuroxylans

o Flavonoids; quercitin, kaempferol, hyperoside, astragalin, rutin, eupatorin

& others

o Miscellaneous: diterpenes - dendroidinic acid, hebenolide; sterols; volatile oil.

Actions : Diaphoretic, bitter, laxative, tonic, anti-spasmodic, carminative, astringent.

Indications : Boneset is one the best remedies for the relief of the associated symptoms that accompany influenza. It will speedily relieve the aches and pains as well as aid the body in dealing with any fever that is present. Boneset may also be used to help clear the upper respiratory tract of mucous congestion. Its mild aperient activity will ease constipation. It may safely be used in any fever and also as a general cleansing agent. It may provide symptomatic aid in the treatment of muscular rheumatism.

Priest & Priest tell us that it is a stimulating, tonic and antispasmodic diaphoretic; indicated for influenzal epidemics and febrile conditions arising in marshy districts. Acts upon the gastro-hepatic organs and promotes secretion and excretion of bile. They give the following specific indications: Influenzal colds & fevers with night sweats and aching bones. Pulmonary inflammation/catarrh with cough and chest soreness. Post-influenzal gastric irritation with biliousness and constipation. Skin diseases & eruptive fevers of hepatic origin.

It is worth quoting from Kings American Dispensatory at length here: As a tonic, it is useful in remittent, intermittent, and typhoid fevers, dyspepsia, and general debility. In intermittent fever, a strong infusion, as hot as can be comfortably swallowed, is administered for the purpose of vomiting freely. This is also attended with profuse diaphoresis, and sooner or later by an evacuation of the bowels. During the intermission, the cold infusion or extract is given every hour as a tonic and antiperiodic. The chill and succeeding fever is slight, the skin dry, and not,as a rule, followed by perspiration; there are pains in the bones, praecordial oppression, and great thirst. If, however, the case is one in which the fever lasts all day, a slight sweating may follow at night. Another indication in ague is vomiting, especially of much bile. Eupatorium given as above, or sometimes in small doses, may relieve headache of intermittant character when the intermissions are irregular. In epidemic influenza the warm infusion is valuable as an emetic and diaphoretic, likewise in febrile diseases, catarrh, colds, with hoarseness and pleuritic pains, and wherever such effects are indicated. In infuenza it relieves the pain in the limbs and back. Its popular name boneset is derived from its well-known property of relieving the deep seated pains in the limbs which accompany this disorder, and colds and rheumatism. often this pain is periosteal, and if neuralgic in character, or due to a febrile condition, Eupatorium will relieve it. But it is not a remedy for periosteal pain due to inflammation or to organic changes in the periosteum. On the other hand, when given until the patient sweats, and then continued in 5-drop doses of specific eupatorium it has relieved the severe nocturnal muscular and "bone pains" of syphilis. It is a remedy for the cough of the aged, that cough in which there is an abundance of secretion, but lack of power to expectorate. The cough of measles, common colds, of asthma, and hoarseness are also relieved by it. Unless given in excess it acts as a good tonic to the gastric functions, increasing the appetite and power of digestion. The stomach disorders of the inebriate are, in a measure corrected by the use of small, tonic doses of Eupatorium.

Combinations : In the treatment of influenza it may be combined with Yarrow, Elder Flowers, Cayenne or Ginger. With Pleurisy Root and Elecampane in bronchial conditions.

Preparations & Dosage : Infusion: pour a cup of boiling water onto l-2 teaspoonfuls of the dried herb and leave to infuse for l0-l5 minutes. This should be drunk as hot as possible. During fevers or the flu it should be drunk every half hour. Tincture: take 2-4ml of the tincture three times a day.


Boneset: a native American Indian herb with antiseptic, anti-viral properties used for the treatment of colds and flus, coughs, fevers, indigestion and pain.


Ginseng

The ancient Chinese believed that the root of the ginseng plant was the crystallization of the essence of the earth in the shape of a man and that ginseng had rejuvenating, recuperative, revitalizing, and curative action. The first and anonymous Chinese materia Medica written by Shen-nong, stated that ginseng was used for its tonic and tranquilizing effects; that ginseng increased alertness, brilliance, and concentration, and improved memory; and that ginseng prolonged use brought about longevity.

Ginseng Benefits:

Increase physical stamina and sexual prowess in both men and women

Enhance blood flow

Erection-booster

Helps regulate blood pressure;

Slow down degeneration of cells in human body

Reduce stress

Calm nerves

Increase metabolism

Strengthen immune system

There are two major ginseng species; Asian ginseng (panax ginseng) and American ginseng (panax quinquefolium) The name of panax derived from Greek, means "all cure" (pan means all, ax means cure). Ginseng meaning "wonder of the world", has been known and respected by the Chinese for centuries. It is true that ginseng possesses real value for improvement of human health. Modern scientific findings on ginseng have well documented many attributed uses and therapeutic effects of ginseng. Tonic action of ginseng has been the most persistent; it is now often described as "tonic up the cerebral cortex" and good to relieve stress (an "adaptogen" activity). Ginseng has a "universal defence action" and meets all 3 requirements for adaptation effects.

1. Ginseng is not toxic and has no side effects. It does not cause any discomfort or disorder in the physiological functions of the body.

2. The action of ginseng is neither local nor specific; i.e. it increases the body's strength and ability of resistance to adverse stress or damages (chemical, physical or biological agents)

3. Ginseng is a regulator , exhibiting normalizing effects of the body , the regulating effects of high or low blood pressure

More about ginseng:

- Ginseng stimulates both physical and mental activity. These effects are found to be more pronounced in tired and weak people.

- Ginseng greatly strengthens and protects the human body from severe or prolonged physical or mental stress

- Ginseng increases physical and mental efficiency, improves accuracy of work, contributes to ones concentration, and prevents fatigue.

- Ginseng stimulates and improves the work of the brain cells. Ginseng is well known to be a powerful regulator of the nervous system

- Ginseng stimulates the function of the endocrine glands.

Ginseng has been used in traditional Asian medicine for a long long time as a general tonic and cardiotonic agent. Scientific studies evidence these biological effects of ginseng and also support the uses of ginseng as an antidote, antitumor agent, and an antidiabetic.

The usage of Asian and American ginseng is very different according to the famous Chinese pharmaceutical compendium and Chinese traditional medicine of Yin Yang.

American Ginseng possesses "cooling" property to the body, while Asian ginseng possesses "warming". Therefore, people with the "warming" body should only take American ginseng which is "cooling" , but people with "cooling" body should only take Asian ginseng instead. Otherwise, contradictions exist, particularly for people with high blood pressure, other diseases and weakness. It is no wonder that American ginseng is often used to reduce stress and fatigue, but not Asian (Chinese and Korean ) ginseng with more stimulating and depleting effects.

Lu, Okauda and Yoshida, Lewis Muwalla and Abuirmeileh, and Kaku et al reported that American ginseng has insulin-like activity, influences neurologic reactions,reduces total cholesterol level and improves heart and blood circulatory functions. American ginseng is found to balance and tone the biochemistry system of the body, strengthen the immune system, provide enormous energy, eliminate the daily fatigue, enhance the body vitality, and improve physical and mental strength. In addition , American ginseng is effective against high blood pressure and cardiovascular diseases.

The differences between American and Asian ginsengs are well documented not only by Chinese traditional doctors, but also by modern scientists, It is found that the differences in the active, constituents may account for the differing medicinal uses of American and Asian ginseng. Shibata's group and Staba and his colleagues found that the types of saponins in American ginseng are similar to those in Asian ginseng, the exceptions that ginsenosides Ra and Rf found in Asian ginseng are absent from American ginseng. There are some differences in quantity of ginsenosides Rg and Re groups between American ginseng and Asian ginseng. Furthermore, the relative abundance of panaxadiols and panaxatrios differs in the two ginseng species. American ginseng contains very few ginsenosides with central nervous system stimulating activity, it is regarded as a "cooling agent".

EFFECTS OF GINSENG ON SPORTS PERFORMANCE

Ginseng has been shown to enhance sports performance. Athletes from beginning joggers to Olympic contenders agree that ginseng helps them overcome the strain and drain of exercise. A recent Swiss study conducted by Dr. Anton Kirchdorfer shows how ginseng helps. Thirty athletes were given exercise tests on a programmed exercise cycling machine to assure a specific level of muscle work. the heart rate and lactate concentration in the blood was measured before, immediately after, and for several minutes following the exercise.

Strong exertion for eight minutes raised the athletes heart rate from an average value of about 70 to 155 (more than doubled). During recuperation, their heart rate slowly returned to normal over a period of about 20 minutes; their heart rates fell below 100 after 4-5 minutes.

The athletes were then given ginseng daily for nine weeks. The tests were conducted again, using the same amount of exercise. Their pulse rates this time increased to only 140, and during recuperation their heart rates fell blow 100 within just 3 minutes, and were back to normal in 5 minutes.

Lactate (the substance that causes muscular pain following exercise was measured during the same tests. Before using ginseng, the lactate levels of the athletes increased from 2.0 before exercise to 10.5 afterward, without returning to normal levels even after 20 minutes. Following nine weeks of ginseng administration, lactate acid levels only reached 6.2 at their highest point, and decreased to normal in about twenty minutes.

These figures show that the athletes were using oxygen much more efficiently after taking ginseng. Thus, their hearts did not need to pump as fast, and they did not produce as much lactic acid, (the by-product of oxygen use). The quicker return to normal physiologic conditions also indicates that there is less stress to the entire system.

The blood carries oxygen to the cells of the body. In the cells, oxygen combines with chemicals obtained from food. Energy produced during the process makes it possible for each cell to perform its function in the body. Ginseng can regulate the basal metabolic rate, often raising it when it is too slow, to increase the breakdown and metabolism of foods, liberating more energy and removing more waste products.

Small protein material in ginseng are responsible for helping sugar and fat metabolism. Also ginsenocides significantly alter the ability of the skeletal muscles to use free fatty acids rather than glucose for energy. Ginseng causes a more economical use of body energy and an extra storage of energy-producing compounds in the liver.


Siberian Ginseng: stimulates T-cell and B-cell activity, energy, libido, body fat burning and many stress-related conditions.


 

Melatonin

Melatonin

The pineal gland, until recently, has been referred to as the mystery gland, since its functions were largely unknown. The pineal is now recognized as a key element in the maintenance of the body’s endocrine regulation (hormone balance), immune system integrity, and circadian rhythm (daily metabolic balance). Melatonin is the principal hormone produced by the pineal gland. Melatonin is under investigation as a treatment for a number of conditions, including jet-lag, seasonal affective disorder (SAD), depression, and cancer. Pineal polypeptide extract (which contains a broad spectrum of other, protein-based pineal hormones) has been shown to inhibit the development of atherosclerosis [Tasca, et al., 1974], reduce blood triglyceride levels [Ostroumova and Vasiljeve, 1976], improve cellular immunity [Belokrylov, et al., 1976; Dilman, 1977], and increase lifespan in animals [Dilman, et al., 1979].

The pineal gland functions as a biological clock by secreting melatonin (along with many other neuropeptides) at night. As you can see from the following illustration, melatonin levels peak at about 2 a.m. in normal, healthy young people and about 3 a.m. in elderly people. The maximum amount of melatonin released in the bloodstream of the elderly is only half of that in young adults.

Melatonin levels are low during the day. At sunset, the cessation of light triggers neural signals which stimulate the pineal gland to begin releasing melatonin. This rise continues for hours, eventually peaking around 2 A.M. (3 A.M. for the elderly) after which it steadily declines to minimal levels by morning. The delay in timing and decrease in intensity of the melatonin pulse is a manifestation of the aging process.

The melatonin pulse regulates many neuroendocrine functions. When the timing or intensity of the melatonin peak is disrupted (as in aging, stress, jet-lag, or artificial jet-lag syndromes), many physiological and mental functions are adversely affected. The ability to think clearly, remember key facts, and make sound decisions can be profoundly hampered by these upsets in the biological clock.

Melatonin for Jet-Lag

Jet-lag is a condition caused by desynchronization of the biological clock. It is usually caused by drastically changing your sleep-wake cycle, as when crossing several time zones during east-west travel, or when performing shift work. Jet-lag is characterized by fatigue, early awakening or insomnia, headache, fuzzy thinking, irritability, constipation, and reduced immunity. The symptoms are generally worse when flying in an easterly direction, and it may take as long as one day for each time zone crossed in order to fully recover. Older people have an even tougher time adjusting to these changes than younger people.

Circadian disturbances can easily result from conditions other than jet travel. We call these “artificial jet-lag syndromes” because jet-lag is universally understood. Artificial jet-lag can be induced by working night shifts, working rotating shifts (like physician-interns, management trainees for 24-hour businesses, and soldiers under battle-alert conditions), or by staying up all night. Whatever its causes, jet-lag and artificial jet-lag syndromes are seriously debilitating to cognitive function.

Melatonin taken in the evening (in the new time zone!) will rapidly reset your biological clock and almost totally alleviate (or prevent) the symptoms of jet-lag. The ability of melatonin to alleviate jet-lag was demonstrated in a study of 17 subjects flying from San Francisco to London (eight time zones away). Eight subjects took 5 mg of melatonin, while nine subjects took a placebo. Those who took melatonin had almost no symptoms of jet-lag (see illustration below) [Arendt, et al., 1986]. Six out of nine placebo subjects scored above 50 on the jet lag scale, and all of the melatonin subjects scored below 17.

Most people sleep well with melatonin, and wake up the next day refreshed with no symptoms of jet-lag [Claustrat, 1992] (although they may still have some fatigue from the wear and tear of traveling).

Many melatonin fans without any noticeable symptoms of circadian disturbance are now using melatonin to enhance their circadian rhythms. They report that it helps them get to sleep and helps them sleep more soundly. It also makes them more alert the next day and even lessens mid-afternoon tiredness (and naps).

In all cases, melatonin should be taken at night (preferably before midnight) before going to bed. That’s when your pineal gland naturally releases melatonin. Taking melatonin at night (or before your normal bedtime if you are a shift worker) helps restore and maintain normal circadian metabolic rhythms.

Does Melatonin Improve or Impair Mental Performance?

We were initially surprised to find a number of studies which reported on adverse effects of melatonin on performance and alertness. One study [Lieberman, 1984] reported that melatonin users were less alert, more sleepy, and demonstrated slowed “choice-reaction time.” Other studies also indicated that melatonin impaired memory and performance [Neville, 1986]. We found, however, that in all of these studies, melatonin was given to subjects in the daytime, before the performance tests, just the opposite of what they should have been doing!

With circadian enhancers like melatonin, the timing is critical. When taken in opposition to the body’s natural circadian rhythm, they cause cognitive deficit just like jet-lag does. But when taken in synchronization with the body’s natural circadian rhythms, they enhance mental performance. By giving melatonin in the daytime, before the cognitive tests, the researchers were causing the test subjects to suffer from artificial jet-lag and then measuring the resulting cognitive impairment. Disruption of circadian rhythms produces amnesia by interfering with the circadian organization of memory processes [Sandyk, 1991].

Melatonin, by correcting circadian rhythms should, theoretically, improve mental performance. We could only find one study in which melatonin was given to rats at night. This study confirmed that next-day measures of learning ability improved [Ovanesov, 1990]. We believe that melatonin, when taken before sleep, will decrease sleep disturbances of any kind, and will, therefore, improve mental function during the following day.

Melatonin for SAD and Depression

Two particularly notable features of depression and SAD are diminished nighttime release of melatonin and abnormal sensitivity to melatonin suppression by light [Brown, 1989]. This has led researchers and clinicians to try melatonin as an experimental treatment for depression, with gratifying results.

Melatonin Extends Lifespan

Melatonin has also been shown to improve immunity and extend lifespan in rodents [Regelson & Pierpaoli, 1987; Pierpaoli, et al., 1990]. Dr. Maestroni [1988] gave melatonin to middle-aged mice each evening. The treated mice became more healthy (better posture, increased activity levels, and thicker, more lustrous fur) and lived an average of 20% longer than control mice.

Melatonin secretion naturally drops off with age (see the following graph). This decrease is so reliable that blood melatonin levels have been proposed as a measurement of biological age [Nair, et al., 1986]. This age-related reduction in melatonin levels may partially account for the reason many older people have difficulty sleeping at night, and for why they are so fatigued during the day. We believe they may be suffering from age-induced “jet-lag.” Restoration of normal sleep-wake cycles in many of my [WD] elderly patients with supplemental melatonin before bedtime has dramatically improved their quality of life.

Melatonin: Anti-Stress Hormone

Nighttime administration of melatonin can also counteract the immune-suppressing effects of acute anxiety stress in mice. Measures used to confirm this were: thymus weight, antibody production, and ability to fight off a lethal viral infection [Pierpaoli and Maestroni, 1987].

Melatonin for Cancer Treatment

Melatonin also appears to inhibit tumor growth. In the United Kingdom, a study was carried out on 14 cancer patients with cancers of different types. The researchers concluded that “this study would suggest that melatonin may be of value in untreatable metastatic cancer patients, particularly in improving their quality of life. Moreover, based on its effects on the immune system, melatonin could be tested in association with other anti-tumor treatments” [Lissoni, 1989].

Melatonin in Alzheimer’s Disease

Very recent studies have found reduced levels of melatonin in the cerebrospinal fluid of patients with Alzheimer’s disease compared to age-matched control subjects [Tohgi, 1992; Skene, 1990]. Since circadian rhythms are disrupted in Alzheimer’s disease, it is interesting to speculate whether restoration of melatonin to normal levels in these patients would alleviate other symptoms as well.

Melatonin and Exposure to Electromagnetic Fields

Sunlight is the primary environmental influence that regulates the internal clock and the associated late-night melatonin pulse. There is some evidence that the earth’s magnetic field may also be an environmental signal affecting circadian rhythms in humans. When shielded from the earth’s ambient magnetic field, human circadian rhythms can become disrupted [Tohgi, 1992].

Exposure to electromagnetic fields from appliances and from powerlines may be even more significant than we think. There are reports of altered neural function from exposure to ELF (extremely low frequency) fields, as found near high-voltage powerlines, including suppressed melatonin levels [Lovely, 1988]. Supplemental melatonin may help to overcome the negative health consequences of these fields.

Dosage

The appropriate dose can vary enormously from person to person. Dr. Pierpaoli, a leading melatonin researcher, has successfully used dosages ranging from 0.1 to 200 mg. That’s a 2000-fold difference between the lowest dose and the highest! Several intelligent melatonin users we know started by taking 3 mg at 11 p.m., and then adjusted the dose from there. If they found that they slept well but were drowsy in the morning, they cut the dose in half. If they found the dose had little or no sleep-inducing effect, they increased the dose by 3 mg each night until they got the desired effect. We have received reports from one person who gets good results from less than one milligram, and several from people who use in the vicinity of 20 mg. Most people get good results with doses between 3 and 10 mg.

Precautions

Timing may be crucial for the most effective use of melatonin. Individual differences in the absorption and metabolism of melatonin may account for the differences in size and timing of the resulting melatonin pulse. A good illustration of this effect is found in the experiences of Dr. Tzischinsky [1992] of the medical university in Haifa, Israel. Dr. Tzischinsky treated an 18-year-old blind man suffering from chronic sleep disturbances. Presumably, the young man’s blindness prevented sunlight from cueing his circadian rhythm. He suffered from daytime fatigue, often falling asleep during the day, but was awake at night. After two unsuccessful treatment regimens with 5 mg and 10 mg melatonin administered at bedtime (10 - 10:30 p.m.), Dr. Tzischinsky tried a third regimen of only 5 mg administered at 8 p.m. for three weeks. This approach resulted in a successful resolution of the man’s sleep disturbances.

This observation (and others like it) demonstrate the importance of not only adjusting the dosage but also the time of the dose. Melatonin seems to be much more critical in this regard than other smart drugs. One melatonin user reports that he gave himself terrible jet-lag by absent-mindedly taking melatonin at 3 a.m. after staying up late. He recovered from this error, resetting his circadian rhythm back to normal with melatonin at 10 p.m. the following evening, but not before he had to spend an entire day in jet-lag hell for his mistake.
