Fu Ling, also known as Wolfiporia extensa, is a wood-decay fungus with numerous historical uses rooted in Traditional Chinese Medicine and Native American culture. This remarkable mushroom promotes health, offering potential benefits such as diuretic properties, anxiety relief, and enhanced digestion. With significant micronutrient content and compounds like triterpenoids and saponins, Fu Ling is being studied for its effects on cancer, diabetes, and renal health. Despite limited side effects reported, caution is advised for pregnant women.
