One of the most remarkable aspects of the research into mushrooms stems from the vast number of mushrooms that dot the landscape. At least 1.5 million types of fungi populate forests, fields, nooks and crannies, but studies have detailed the properties of less than 3,000.

Compound Interest
Mushrooms produce so many beneficial compounds because they constantly fight off other fungi and microbes to survive. These substances, which mushrooms utilize for defense, can apparently help humans.

One of the most important of these classes of compounds are the polysaccharides. Scientists believe these long starch molecules spark immune action that can protect us against invading germs or cancer. They may do this by persuading the body to create what are called killer T-cells. These immune warriors destroy microscopic invaders and may help stop tumors.

According to Paul Stamets, author of Growing Gourmet and Medicinal Mushrooms (Ten Speed), use of polysaccharides... "will synergistically, in combination with the individual's immune system, result in dramatic recoveries...Right now we don't clearly understand all the elements in those formulas to be able to predict downstream what will happen. But clearly with some people, it is tremendously effective" (Townsend Ltr, 6/98).

In addition, mushrooms also make biologically active chemicals called steroids and terpenes, says Christopher Hobbs, author of Medicinal Mushrooms (Interweave). These substances are thought to help fight off the formation of cancerous tumors.

Maitake: Useful Fungus
Maitake (Grifola frondosa) mushrooms, also known as "Hen of the woods," contain chemicals called beta glucans that can enhance immunity. Scientists are particularly fascinated by substances called the "D-fraction." Studies show these can spur immunity (Biol. Pharm. Bull. 17(12), Dec. 1994: 1554-60).

Researchers are also looking into the possibility that Maitake can help people with AIDS regain weight. And scientists are examining their effect on high blood pressure and diabetes.

Reishi's Effects
In Tibet, the Reishi mushroom (Ganoderma lucidum) has long been used to battle altitude sickness in the Himalayan mountains. Reishi is also reputed to soothe frayed nerves.

Scientific studies have supported these traditional uses, finding that people who consumed Reishi functioned better in low oxygen (Proceedings Contrib Symp 59 AB, 5th Intl Cong, 8/14-21, 101-104). Other research finds Reishi may help ease arthritis (Proc 1st Intl Symp on Ganoderma l. 11/17-18, 99-103, Tokyo).

Lion's Mane
Lion's Mane (Heri-cium erinaceus), also called "Monkey's head," has traditionally been a treatment for stomach problems in China. But researchers have found that chemicals in this mushroom help fight tumors (Biosci Biotech Biochem 56(2), Feb. 1992: 347-8).

During the past few years, scientific investigators have also begun to extract chemicals called erinacines from lion's mane. These substances, (known as Nerve Growth Stimulant factor) appear to encourage neuron regeneration. The potential uses: boosting nerve performance, fixing neurological damage and treating Alzheimer's disease (Tetrahedron Ltrs 35(10), 1994: 1569-1572).

Divine Fungus
Known as Cogmelo de Deus (Mushroom of God) in Brazil, the Royal Agaricus (Agaricus blazei) has been grown in Japan since the '70s where it enjoys widespread popularity. Researchers find that it provokes powerful anti-tumor effects. This fungus harbors more beta-glucans, immunity enhancers, than other mushrooms.

Mushroom Performance
Can a fungus make athletes faster? A few researchers think so, pointing to Chinese Olympians who use Cordyceps sinensis. This fungus, traditionally grown on caterpillars, is another native of the Himalayas.

Traditionally, Cordyceps has been used to foster stamina, better breathing and immunity.

At least one study shows this fungus may help blood vessels dilate during exercise. By supplying extra blood to working muscles, Cordyceps may help fight off fatigue and boost performance (Abstracts from 5th Mycological Cong, Vancouver, 8/14-21).

Research Extravaganza
The mushroom called Shiitake has been the subject of an extravagant amount of research since the '60s. Called the "elixir of life," it boosts immunity. Stamets reports that people with cancer who take Shiitake do significantly better in coping with their disease (Abstract 2nd Meeting Soc of Natl Immunity, Italy, 5/25/94).

Another characteristic of Shiitake mushrooms: a celebrated taste. The tongue and the palate take great pleasure in this health enhancer!
