The word lingzhi, in Chinese, means “herb of spiritual potency” and has also been described as “mushroom of immortality”. Because of its health benefits and absence of side-effects, it has attained a reputation in the East as the ultimate herbal substance. Lingzhi has also been added to the American Herbal Pharmacopoeia and Therapeutic Compendium.
