About Reishi Mushroom

Reishi (Ganoderma lucidum and related species) is the most revered mushroom in traditional Chinese and Japanese medicine, used for over 2,000 years. It grows as a woody, varnished, kidney-shaped bracket with a distinctive red-lacquered upper surface. Wild reishi is too tough and bitter to eat directly — it is used as a medicinal tea, tincture, or extract.
