Phellinus linteus - An Increasingly Popular Korean Medicinal Mushroom

By Dr. Markho Rafael

A new medicinal mushroom from Korea is gaining reputation around the world at record pace. Most commonly known by its Latin name as Phellinus linteus, it is also sometimes referred to as Mesima (Japanese), and rarely by its English name, Black Hoof Fungus.

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]

Years later, American world-renown mycologist Paul Stamets helped deepen our understanding of Phellinus linteus when he published a comparative analysis with the most common medicinal mushroom species: Agaricus blazei, Lion's Mane, Chaga, Reishi, Maitake and Cordyceps. [18]

Phellinus linteus had a stronger effect than any of them on the part of the immune system known as macrophages. The activity of this type of white blood cell increased by 5,700% when Phellinus linteus extract was administered in an amount equivalent to 3,750 mg for an average size adult (165 lbs). [18]

It should be noted that macrophages may promote cancer growth as well as fight cancer. The research that has been published about Phellinus linteus extract indicates that it enhances the anti-cancer properties of macrophages. [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. A Korean journal published a paper in 2005 which reported on a "spontaneous regression of a large hepatocellular carcinoma with skull metastasis." The 65-year-old patient had "ingested mushroom called Phellinus linteus for one and a half years." [17]

3. Finally, an article published 2006 in the Japanese journal Radiation Medicine told of a "patient with hepatocellular carcinoma with multiple lung metastases in whom malignancy spontaneously regressed after taking Phellinus linteus Mycelium." The 79-year old patient reportedly "took extract from Phellinus linteus Mycelium for one month, and 6 months later the tumors appeared to be in complete regression." [16]
