Phellinus linteus – Medicinal Mushroom’s Popularity Exploding World-wide
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. 
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 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.
Word of Phellinus linteus caught on in’96 when a Korean paper got published, which credited it with the widest range of anti-tumor and immune-enhancing properties of any medicinal mushroom extract. 
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. 
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). 
Although human macrophage cells have been known to both induce and inhibit cancer growth, the published research on Phellinus linteus shows that it promotes the anti-cancer properties of macrophages rather than their potential cancer-inducing 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.” 
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. 
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.
