Medicinal Mushrooms in 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.

Birch polypore and Tinder fungus are both polypores, which have pores on their undersides, hence the name. Most polypores grow on trees and none is known to be poisonous.

Polypores are usually considered inedible due to the fact that they are hard and wood-like. But for ancient peoples all across the globe - from China and India to Europe and the Americas - polypore teas and poultices have none-the-less been indispensible allies to human health at least for as long as written and oral traditions can recount.

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.

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.

Modern research into medicinal use of mushrooms began in earnest in the late 1960's Japan. One pioneer, Dr. Ikekawa, discovered that families of mushroom growers had significantly lower cancer rates than their surrounding communities. Scientific research into medicinal mushrooms has expanded exponentially since that time and continues to increase and intensify until this day. Medicinal mushrooms are still in the process of making history.
