Maitake (grifola frondosa)

Maitake (grifola frondosa) aerial

Maitake mushrooms contain quite a few immunity-boosting and anti-cancerous properties. They help boost the immune system through a fiber called beta glucan. Beta glucan increases production of immune system cells, both in your blood and tissues. Maitake mushrooms also help fight cancer through this effect, by producing white blood cells that fight tumors.
