Poria mushroom is a fungus. The filaments, threads in which food material is stored, are used for medicine.

In traditional medicine, poria mushroom filaments have been used for loss of memory (amnesia), anxiety, restlessness, fatigue, tension, nervousness, dizziness, urination problems, fluid retention, sleep problems (insomnia), an enlarged spleen, stomach problems, diarrhea, tumors, and to control coughing.

Poria filaments have been used in various herbal combination products for treating diarrhea, ongoing kidney inflammation (chronic glomerulonephritis), ringing in the ears (tinnitus), and for decreasing upper gastrointestinal (GI) tract bleeding.

How does it work?

Poria mushroom contains chemicals that might improve kidney function, lower serum cholesterol, reduce inflammation, and suppress immune function. It might also have antitumor and anti-vomiting effects.
