Hailed in ancient Eastern medicine as the "mushroom of immortality" and the "medicine of kings," you'd expect reishi to offer you some pretty astounding health benefits, right? Your assumptions are correct. This prized fungus may be able to boost your immune system, fight cancer, ward off heart disease, calm your nerves and relieve both allergies and inflammation.

"Reishi indeed sounds like a cure-all," writes Rebecca Wood in her book "New Whole Foods Encyclopedia." She goes on to explain reishi's wide range of uses: "An immunostimulant, it is helpful for people with AIDS, leaky-gut syndrome, Epstein-Barr, chronic bronchitis and other infectious diseases. It is used as an aid to sleep, as a diuretic, as a laxative and to lower cholesterol." It almost seems too good to be true.

How can one fungus help the human body in so many ways? Traditional Eastern medical science explains reishi's wide range of medicinal applications better, perhaps, than mainstream medicine ever could. According to Eastern thought, the body needs to defend itself against threats to its "equilibrium." These threats can be physical, such as viruses and bacteria that cause infection; emotional, such as stressors that cause anxiety; or energetic, in that they reduce alertness. Whatever the threat, reishi helps the body maintain its defense against these threats to its equilibrium, helping the body to maintain balance. In this sense, diseases like heart disease and cancer mean that the body is out of balance, which is why an equilibrium-enhancing remedy such as reishi can help so many diverse ailments.

Skeptics can doubt the previous explanation as Taoist "mumbo jumbo," but laboratory research proves many of reishi's medicinal applications. As Dr. Andrew Weil writes, reishi "has been the subject of a surprising amount of scientific research in Asia and the West." Research shows that the polysaccharide beta-1,3-D-glucan in reishi boosts the immune system by raising the amount of macrophages T-cells, which has major implications for people suffering from AIDS and other immune system disorders.

This immune-boosting action also works wonders in the prevention and treatment of cancer, as the T-cells are then able to fight cancer cells more effectively. However, reishi may help the body defeat cancer in not just one, but four ways. In addition to boosting the immune system, the glucan in reishi helps immune cells bind to tumor cells. Many experts believe that it also actually reduces the number of cancerous cells, making it easier for T-cells and macrophages to rid the body of them. Another substance in reishi, called canthaxanthin, slows down the growth of tumors, according to "Prescription for Dietary Wellness" author Phyllis A. Balch and other experts. As a result of these amazing anti-cancer abilities, laboratory research and traditional medicinal usage of reishi to fight cancer is so positive that the Japanese government officially recognizes it as a cancer treatment.

Besides cancer, reishi can help and treat another of America's top killers: cardiovascular disease. The protection reishi offers against heart disease and stroke is truly remarkable because it helps prevent so many different risk factors, due to its high content of heart-saving substances like sterols, ganoderic acids, coumarin, mannitol and polysaccharides. Experts believe that the ganoderic acids in particular lower triglyceride levels, remove excess cholesterol from the blood, lower blood pressure, reduce platelet stickiness and even help correct arrhythmia. In fact, for 54 people with hypertension unresponsive to medication, taking reishi extract three times a day for four weeks was enough to significantly lower blood pressure, according to a study reported by Burton Goldberg in "Heart Disease." Just imagine how the incidence of cardiovascular disease could be reduced if using reishi really caught on in the Western hemisphere.

While you protect your body against infectious disease, cancer and heart disease, your use of reishi can also help relieve your everyday discomforts. Do you have allergies? Japanese researchers discovered that the lanostan in reishi acts as a natural antihistamine. Do you suffer from muscle aches or arthritis? Dr. William B. Stavinhoa of the University of Texas Health Science Center found that reishi is as powerful as five milligrams of hydrocortisone, but with minimal side effects. What about anxiety or insomnia? According to "Mind Boosters" by Dr. Ray Sahelia, the reishi mushroom can calm the mind, as well as improve memory, concentration and focus. With all these benefits, reishi truly is the "medicine of kings."

Different types of reishi

Though there are six different types of reishi, all classified by color, herbalists generally call red reishi the most potent and medicinal variety, and thus it is the most commonly used form of reishi in North America, Japan, China, Taiwan and Korea. In the wild, the mushroom grows on deciduous trees in heavily forested areas of China and Japan, but it's now easily and widely cultivated commercially, so you don't have to venture into the forest to enjoy the benefits of what "Herbal Medicine-Maker's Handbook" author James Green calls a "remarkably beneficial fungus for the human body."

However, keep in mind that reishi isn't exactly the kind of mushroom you'll want to put in your next salad, either. Since it's more than 90 percent indigestible fiber, reishi has an extremely wood-like texture and to top it off, it's unpleasantly bitter. In spite of this bitter flavor, many reishi enthusiasts use ground reishi to make a life-enhancing tea or even use the mushrooms in soups. For the less daring, many health food stores offer reishi capsules, tablets and extracts, and Japanese research suggests taking vitamin C along with it may enhance reishi's medicinal effects.

So, how much reishi should you take? In the "Vitamin Bible for the Twenty-first Century," vitamin expert Earl Mindell advises an average dose of 100 milligrams of reishi extract daily to boost your immune system, reduce inflammation and ease joint pain. On the other hand, Dr. Linda B. White recommends up to three 1,000-milligram tablets up to three times per day in her book "The Herbal Drugstore." Because of this wide range of dosage suggestions and additional risks it might pose for pregnant or lactating women (even though reishi has no known toxicity) you should check with a physician, preferably a naturopath, before adding reishi to your regimen. Similarly, you should be aware that reishi does have some side effects, including abdominal upset, dizziness, nose bleeds and dry mouth and throat, according to "Natural Pharmacy" author Schuyler W. Lininger. In other words, it's up to you and your naturopath to decide which dose of reishi is right for you.

Reishi's wide range of medicinal applications

Health Benefits: Reishi indeed sounds like a cure-all. An immunostimulant, it is helpful for people with AIDS, leaky gut syndrome, Epstein-Barr, chronic bronchitis, and other infectious viruses. It is used as an aid to sleep; as a diuretic; as a laxative; and to lower cholesterol. Reishi mushrooms are antioxidants and liver protectants..
New Whole Foods Encyclopedia by Rebecca Wood, page 288

One key function, identified long ago by Eastern medical science, is defense--that is, the body has the need and a

bility to defend itself against threats to its equilibrium, whether they be physical, emotional, or energetic. Having noted and studied the body's defensive capabilities, Chinese doctors then explored the natural world to find ways of maintaining and enhancing them, and they discovered a number of ways to do so, including the administration of herbal remedies. Among these remedies are ginseng, astragalus, and several mushrooms that grow on trees, such as Ganoderma lucidum (known to the Chinese as ling chih and the Japanese as reishi).
8 Weeks To Optimum Health By Andrew Weil MD, page 15

Not all of the active components in reishi have been isolated; like many other organic substances, the molecules in this plant are quite complex, though they are probably mostly polysaccharides and peptides. Dr. Terry Willard, a proponent of the medical uses of this mushroom, maintains that reishi also decreases free radicals by 50.4 percent through an as yet, unidentified antioxidant. ... Other researchers suspect that reishi may not have an antioxidant of its own but rather stimulates production of the body's own free radical scavenger, an enzyme called superoxide dismutase (SOD). According to the Bulletin of the Oriental Healing Arts Institute, reishi acts as an agent for promoting an increase in leukocytes, phagocytosis which in turn increase the number of disease-fighting T-cells in the bloodstream.

These powerful adaptogens -- Siberian ginseng, schisandra, ginseng, astragalus, and reishi--are among what Teeguarden calls the "superstars of Chinese tonic herbalism . . . incomparable, legendary herbal substances [that] have withstood the test of time." These five herbs also tend to be the ones with the most scientific backing for their strengthening and normalizing effects.

Reishi and the immune system

Reishi is a purely medicinal mushroom, not a culinary one, both because it is hard and woody and because it tastes very bitter. But it is nontoxic and has been the subject of a surprising amount of scientific research, both in Asia and the West. Although most of the research has been in animals, the results are so promising that I think human studies will soon follow. Like maitake and other related mushroom species, reishi improves immune function and inhibits the growth of some malignant tumors. Additionally, it shows significant anti-inflammatory effect, reduces allergic responsiveness, and protects the liver.

Reishi Mushrooms Known as kisshotake or the "lucky fungus," in Japan, reishi mushrooms were originally used in China in both cooking and traditional healing. However, for several thousand years the Japanese have used these delicately flavored mushrooms in their cuisine. reishi mushrooms, which are quite pricey, are available in Asian markets and gourmet shops. However, they may be worth their weight in gold. Recent studies show that reishi may stimulate the immune system, which increases the body's ability to ward off disease. In addition, reishi mushrooms contain compounds that are natural antihistamines and have strong anti-allergic activity. Other studies show that reishi can lower blood cholesterol levels and prevent the formation of dangerous blood clots that can lead to a heart attack or stroke..

Mushrooms, particularly Eastern varieties, revitalize the body. Various cultures consider them to contain the secrets of staying young. Reishi and shiitake mushrooms build resistance to stress by strengthening the immune system. They also provide key B vitamins to the liver and stimulate the adrenals with their high concentration of pantothenic acid. The common American button mushroom contains methionine, an amino acid high in sulphur. When combined with tofu, the result is a more complete protein.

All edible mushrooms contain both medicinal and nutritional qualities. Scientific research indicates that the major actions of medicinal mushrooms are stimulating the immune system and protecting against cardiovascular disease, free radicals, mutagens, and toxins. Most medicinal mushrooms contain polysaccharides (complex sugar molecules) called beta-glucans that increase RNA and DNA in the bone marrow where immune cells, like lymphocytes, are made. The combination of compounds in mushrooms is believed to target the immune system and aid in neuron transmission, metabolism, and the transport of nutrients and oxygen. Three mushroom varieties -- reishi, shiitake, and maitake -- have been studied intensively and have proven to possess strong medicinal properties. All mushrooms must be cooked to get the nutritional value. The cell walls cannot be digested unless they are tenderized by heat.

Ganoderma: Ganoderma lucidum, the Chinese "mushroom of immortality" called ling zhi (in Japan, reishi) has been extensively studied in the laboratory for antiviral activity and is well known for its immune-modulating activity. My teacher of Chinese medicine, the late Dr. York Why Loo, kept a specimen of dried wild Chinese ling zhi in a jar for use in his old age. So revered by Chinese doctors is ling zhi that it is frequently pictured on their business cards or displayed in their shop windows as a sign of respect for its importance.

The reishi mushroom is traditionally used in Chinese medicine for asthenia-type syndromes, characterized by a deficiency of vital energy and functions of the lower body. reishi is the perfect remedy for the typical American suffering from constant stress. This type of individual has depressed vital force and is likely to be both deficient and toxic. When a person in such a state develops cancer and is then faced with the toxicities of chemotherapy, the situation calls for reishi. reishi's overall effects could be described as regulatory and beneficial to the restoration of homeostasis. Its effect on the immune system is total enhancement of immune function: increase of white blood-cell count, platelets, hemoglobin, and various tumor-fighting cells. reishi also improves both energy and sleep.
