My Prosperous World

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 Korea, its reputation has spread like wildfire around the world. Doctors across the globe are now beginning to use it as an immune booster [2-11], and especially for preventing cancer metastasis. [5,10,12-17] Apart from Korea, Phellinus linteus is particularly popular in Japan, the U.S., and the Middle East from Israel to Turkey.

Perhaps it all got started when one of the first Korean studies on Phellinus linteus in’96 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]

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]

Three additional papers have been published with reports of patients using Phellinus linteus extract and experiencing “spontaneous” regression:

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]
