Ganoderma Lucida (Chinese: Ling zhi, Japanese: Reishi) is the famous tonic mushroom of China; Ling zhi means "spiritual mushroom." According to Shen Nung, author of The Divine Husbandman's Classic of the Materia Medica (ca. 150AD), it "benefits Heart Qi, tonifies the Middle Burner, and increases insight and intelligence." Used traditionally as a qi tonic and sedative and is considered an important immune-enhancing and anti-stress herb. It also reduces hypertension, lowers cholesterol and relieves bronchitis and asthma. There are many legends in chinese culture linking Ganoderma to longevity.

The color of the ganoderma is said to impart certain functions according to Five Element theory. Black ganoderma activates the body's water-circulation system and Kidney function. Red stimulates the functions of the Heart, internal organs and brain. Ganoderma must be cooked into a tea. Use 9-15 grams per four cups water. Cook for 40-60 minutes or longer.
