In addition to the mushrooms known to us, which we treat as simple food, there are several types of mushrooms that have healing properties and are valued more than gold. Most of these mushrooms grow in China, Tibet, and Japan. The most famous of the medicinal mushrooms are shiitake, meitake, reishi, coriolus and cordyceps. A common useful property of these mushrooms is the content of special polysaccharides that can slow down the development of tumors and treat many diseases, from infectious to bacterial and fungal. In Japan, the term fungotherapy (treatment with mushrooms) even appeared.)
