Phellinus linteus Mushroom Used in Korea as Cancer Therapy Adjunct
There's a new star on the medicinal mushroom sky. It goes by Phellinus linteus in Latin. The little known English common name is Black Hoof Fungus. It's far more common, even in America, to hear it referred to by its Japanese name as Mesima.
Phellinus linteus grows on hardwood trees such as oak, poplar and mulberry. The species is common in Southeast Asia and southern parts of the United States. [1]
Most medicinal mushroom species used today in America came to us via China or Japan. Phellinus linteus is a break from this trend, as it first became popular in Korea where it's commonly used to complement traditional cancer treatment.
From there, the fame of Phellinus linteus has spread across the globe. Doctors all over the world now use it as an immune enhancer [2-11], particularly to prevent cancer metastasis. [5,10,12-17] In addition to Korea, Phellinus linteus is today also increasingly popular in the U.S., Japan, and the Middle East from Turkey to Israel.
It may have all began when a 1996 Korean study reported that Phellinus linteus extract exhibited a broader range of immune enhancing and anti-cancer properties than the extracts from other species of medicinal mushrooms. [4]
Seven year later, in confirmation of the Korean finding, America's best known mycologist Paul Stamets published a paper which compared Phellinus linteus to several of the most highly regarded species of medicinal mushrooms: Cordyceps, Reishi, Lion's Mane, Chaga, Maitake and Agaricus blazei. [18]
In this study, Phellinus linteus turned out to have the most powerful effect on enhancing the activity of macrophages, a type of white blood cell that's an important part of the immune system. Macrophage activity was increased 5,700% by the Phellinus linteus extract. The dose used was equivalent to 3,750 mg for an average (165 lbs) adult. [18]
Macrophages as part of the human immune system can be a two-edged sword. They may devour cancer cells, but can also stimulate cancer growth. The published research on Phellinus linteus indicates that it activates the cancer-fighting properties of macrophages, not the cancer-stimulating properties. [8,14,19,20]
In addition to these studies, there are at least three published cases of spontaneous regression of cancers after patients of their own accord used Phellinus linteus extract:
1. A 2004 paper out of Japan reported "a hormone refractory prostate cancer patient with rapidly progressive bone metastasis who showed dramatic response to intake of an extract from the mushroom, Phellinus linteus." [15]
2. In 2005, a Korean paper related the case of a 65-year-old patient with liver cancer and skull metastasis who experienced "spontaneous regression" after one and a half years of using Phellinus linteus. [17]
3. A Japanese article from 2006 reported the case of a 79-year-old man with malignant liver cancer and lung metastases who exhibited complete regression of the tumors six months after using an extract of Phellinus linteus Mycelium. [16]
