History of Medicinal Mushrooms

By Dr. Markho Rafael

During the European "Copper Age" five thousand years ago, a man of high ranking status fled his home valley of Val Venosta, Italy, across an Alpine glacier. But his enemies caught up with him. An arrow penetrated his subclavian artery, which soon bled him to death. In 1991, two unsuspecting tourists came upon his mummified remains. On the body of "Oetzi the Iceman" were found pouches with two medicinal mushroom species, the oldest known example of mushrooms used medicinally.

One of the mushrooms was Birch polypore - Piptoporus betulinus - which it is believed he used as a remedy against intestinal parasites. Eggs of the whipworm parasite (Trichuris trichiura) were found in his intestines. The other mushroom in the possession of Oetzi was Tinder fungus - Fomes fomentarius - which has been traditionally used in Europe to cauterize wounds and stop bleeding.

Both species belong to the group of mushrooms known as polypores, so named because of the many pores underneath. They often grow on trees, and to date no species is known to be poisonous to humans.

With a couple of notable exceptions, most polypores are inedible because they are woody and fibrous. But as natural remedies in the form of tea, extracts and poultices, they have been invaluable to people all across the globe for many millennia.

In North America, some Indian tribes used polypore extracts as remedies against smallpox and other illnesses that arrived with the Europeans. Birch polypore was among these. Other polypores used were Chaga (Inonotus obliquus), Reishi (Ganoderma resinaceum), Turkey tail (Trametes versicolor), and the now threatened species Agarikon (Fomitopsis officinalis).

And as though by no coincidence, Agarikon also holds the distinction as the oldest medicinal mushroom in historic European literature. In 65 B.C., Greek physician Dioscorides recorded it in Materia Medica as a remedy for tuberculosis. More recently, K. Grzywnowics in a 2001 article titled Medicinal Mushrooms in Polish Folk Medicine said Agarikon tea was traditionally considered an elixir for long life and listed historical uses to include lung conditions (coughing, asthma) and rheumatoid arthritis, but also infected wounds and open bleeding.

Up to this point, we've only covered the use of medicinal mushrooms in the West. However, their use has been far more widespread in Asia. There are at least three Asian species that would be criminal to leave out of any article on the history of medicinal mushrooms.

First is the polypore Reishi (Ganoderma lucidum), which has been used in China and Japan as a health bestowing mushroom of immortality for at least two millennia. It was first mentioned in the 2,000 year old book Shen Nong's Herbal Classic. Many ancient wood-carvings and temple engravings in the Orient bear testament to the homage paid to this acclaimed cure-all mushroom.

Another Chinese medicinal mushroom known as Cordyceps was first described in the 200 A.D. book The Classic Herbal of the Divine Plowman. Cordyceps was, and still is, largely used as an aphrodisiac and to improve physical prowess in athletes, although modern research also indicates many other areas of potential usefulness.

Last but not least is the medicinal mushroom Shiitake, better known as a culinary delight. However, Shiitake is also one of the most research mushrooms for medical properties. Commercial cultivation of Shiitake began about a thousand years ago in China. Medicinal uses include immune enhancement, antibiotic and more. Shiitake extracted Lentinan polysaccharide is approved as an anti-cancer drug in Japan.

Scientific research on medicinal mushrooms began in Japan in the late 1960's. A ground-breaking study by Dr. Ikekawa found that mushroom growers and their families had lower cancer rates then the communities in which they lived. Today, medicinal research into mushrooms has expanded exponentially around the world and is still increasing. Medicinal mushrooms are still making history.
