Phellinus linteus - An Increasingly Popular Korean Medicinal Mushroom

By Dr. Markho Rafael

Out of Korea comes a new and increasingly popular medicinal mushroom known as Phellinus linteus. It does have a rarely used English common name, Black Hoof Fungus. But you are more likely to hear it referred to by its Japanese name as Mesima.

Phellinus linteus is common in Southeast Asia as well as the southern United States. It grows on hardwood species of oak, mulberries and poplar, and sometimes on pines. [1]

Unlike most medicinal mushroom species, which were originally used in China or Japan, Phellinus linteus first became popular in Korea as a complement to traditional cancer therapies such as radiation and chemotherapy.

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.

Perhaps it all got started when one of the first Korean studies on Phellinus linteus in 1996 reported that it exhibited a wider range of immunostimulation and antitumor activity than polysaccharides isolated from other medicinal mushroom species. [4]

World renown American mycologist Paul Stamets took this a step further when he published research in 2003 which compared seven of the world's most popular medicinal mushroom species, including Reishi, Cordyceps, Maitake, Chaga, Lion's Mane 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]

Additional reports have been published on cases of "spontaneously" regressed cancers, where the patients reported having used Phellinus linteus by their own choice:

1. First out was a Japanese article in 2004 with a case study of a patient with hormone refractory prostate cancer and bone metastasis who exhibited "dramatic remission" after using Phellinus linteus extract. [15]

2. Next out was a Korean article published in 2005, which reported on a patient who "ingested mushroom called Phellinus linteus for one and a half years" before exhibiting "spontaneous regression" of liver cancer and skull metastasis. [17]

3. And then one year later, in 2006, another Japanese article was published on "a case of spontaneous regression of hepatocellular carcinoma with multiple lung metastases." The 79-year-old patient had been taking an extract of Phellinus linteus Mycelium for a month. When examined by his doctor 6 months later, his tumors had disappeared. [16]
