Description: Called Fu Ling, also known as Poria cocos, hoelen, tuckahoe, China root, fu shen, matsuhodo. Fu ling comes from the Poria cocos fungus, found in the Polyporaceae family. These fungi often colonize things like tree trunks and roots, with a large mycelium hidden below the surface while the fruiting bodies of the fungus are visible to mushroom hunters. Fu ling happens to favor the ground around pine trees, and it is sought out much like the European truffle. The part of the mushroom which is used is the sclerotium, a hardened compact part of the mycelium which stores up energy for the fungus. It is collected between July and September. The poria with reddish inner side of the superficial layer is called red poria and the poria with white inner side of the superficial layer is called white poria. Fu ling is an herbal remedy used in the practice of Traditional Chinese Medicine (TCM). It is extracted from a fungus which is found widely around the world. Many cultures including the Native Americans used fu ling to treat various health problems. Many Chinese herbalists and markets carry fu ling in a variety of forms, and it is also included in a number of tonics which are designed to promote general health. Harvesting fu ling is not recommended unless you are very familiar with mushrooms.
The mushroom is sweet and tasteless in flavor, neutral in property, acting on the heart, spleen and kidney channels. The mushroom is used for inducing diuresis, excreting dampness, invigorating the spleen, replenishing the middle-jiao, and tranquilizing the mind. Fu ling is used as a general purpose yin tonic, promoting health and balance in the body.
