Fungi Used as Medicines throughout History

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.

Oral traditions of Native Americans bear tale of many types of polypores being used to help against the diseases brought by the Europeans, including Birch polypore but also Reishi (Ganoderma resinaceum), Turkey Tail (Trametes versicolor), Chaga (Inonotus obliquus) and the now almost vanished species Agarikon (Fomitopsis officinalis).

Although nearly extinct today, Agarikon was once common in the old-growth forests of ancient Europe. Greek physician Dioscorides referred to Agarikon as a remedy for tuberculosis in Materia Medica, 65 B.C. It's the earliest record of a medicinal mushroom in European literature. Two millennia later, the historic use of Agarikon in Poland was put down in writing in the article Medicinal mushrooms in Polish Folk Medicine by K. Grzywnowics. Again, it included lung conditions, as well as rheumatoid arthritis and infected wounds.

So far, we've only covered the history of medicinal mushrooms in Europe and America and have barely even touch upon their use in Asia, where their use has been even more exhaustive. At least three Asian species must be included in any article on the history of 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.

Next is a mushroom from Tibet known as Cordyceps, a small fungus growing out of the bodies of silk caterpillars. Its first mention was in The Classic Herbal of the Divine Plowman, 200 A.D. Traditionally used as an aphrodisiac, today it's popular with athletes to improve strength and stamina.

Finally there is Shiitake, the number one gourmet mushroom of the Orient. Shiitake has been cultured in China for approximately 1,000 years as a food. What is less known is that it is also one of the most researched medicinal mushrooms in the world. A polysaccharide extracted from Shiitake is approved in Japan as an anti-cancer drug. Other qualities hinted at by research include antibiotic and immune enhancer.

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.
