Pin Yin Name: Fú Línɡ.

Brief introduction: The herb Poria is the dried sclerotium of the fungus Poria cocos(Schw.) Wolf(family Polyporaceae), used (1).as a diuretic in cases of edema and oliguria,(2).to invigorate the spleen for treating anorexia and diarrhea, and (3).to induce tranquilization in cases of palpitation and insomnia. The herb is commonly known as Poria, Poria Cocos, Fú Línɡ.
Botanical source: Common famous herbal classics and official herbal classics defined the herb Poria(Poria Cocos) as the dried sclerotium of the species (1). Poria cocos(Schw.) Wolf, it is a fungus of the Wolfiporia genus, the Fomitopsidaceae family, the Polyporales order. This commonly used species is introduced as:
(1).Poria cocos (Schw.) Wolf.: Botanical description: The Poria cocos (Schw.) Wolf., is a fungus of the Polyporaceae family and Wolfiporia genus, it is also known as "Wolfiporia extensa", "Wolfiporia extensa (Peck) Ginns (syn. Poria cocos F.A.Wolf)", the fungus is also known as "hoelen, poria, tuckahoe, China root, fu ling.", and classified into Fomitopsidaceae family in some latest classification system. Sclerotia spherical, oval to an irregular shape, length is 10~30 cm or longer, the weight is not the same, usually weighing 500~5,000 grams. Thick and wrinkled skin outside, dark brown, hardened when fresh, soft and dry, white or light pink inside, powdery and granular. Entomophores grow in the surface of the sclerotia, all flat, thickness 3~8 cm, white, fleshy, aged or dried into a light brown. Trichoderma long 2~3 mm thin tube wall, nozzle round, polygonal or irregular shape, diameter 0.5~1.5 cm, split lip toothed. Spore rectangular to nearly cylindrical, smooth, with a crooked tip, size (7.5~9) μm × (3~3.5) μm.
The Poria showed three different morphological characteristics at different stages of development, namely mycelium, sclerotia and fruiting bodies.
(1).Mycelium, including mononuclear and dual-core two mycelia. Monomer nuclear mycelium, also known as primary mycelium, is made by the Poria spores germination, only in the early germination. Binuclear mycelium, also known as secondary mycelium, is the main form of mycelium, by two different sex mononuclear mycelia meet, by the quality of the formation. Mycelium was white fluffy appearance, with a unique multi-concentric ring-shaped colony. Observed under a microscope, we can see mycelium by a number of branched mycelia, hyphae by the diaphragm is divided into linear cells, the width of 2-5 microns, the top common to the lock-like joint phenomenon.
(2).Sclerotia, by numerous hyphae and nutrients, gathered from the dormant body. Also known as "Tuckahoe or fu-ling". Spherical, ellipsoid, oblate or irregular lumps; small two, the largest number of pounds, tens of pounds; fresh matter soft quality, easy to open, hard to break open after the hard. Sclerotium outer shell-like, rough surface, with tumor-like shrinkage, fresh light brown or tan, dry to dark brown; skin white and light brown. Observed under a microscope, the mycelium in the white part of the mycelium was mostly lotus-like joints or extruded mass. Near the skin at the more slender and arranged dense light brown hyphae.
(3). Fruiting bodies, usually produce on the surface of sclerotia, occasionally in the older mycelium. Honeycomb, different sizes, sessile supine, about 0.3~1 cm thick. At first white, the old woody into light yellow. The stratum is born on the surface of the inner wall of the tube and consists of numerous heavy loads. Mature burdens each produce 4 spores (ie basidiospores). Poria spores gray-white, oblong or nearly cylindrical, a crooked tip, 6×2.5 ~ 11×3.5 microns.
Ecological environment: The Poria cocos is parasitic on the pine family of plants such as red pine or Masson pine roots, 20 to 30 cm underground. The herb distributes in the lower reaches area of the Yangtze River, the Zhujiang river area, north and northwest area, and other areas of China.
Growth characteristics: The poria cocos is a facultative parasitic fungus, it grows wild in the rhizosphere of Pinus massoniana, Pinus yellow-mountain, Pinus red, Pinus yunnanensis, Pinus lodgepole, and other tree species, on dry and sunny slopes in mountainous areas of 600~1000 meters altitude. 10°-35° mountain slope and sandy soil are more suitable for its growth. It is favorable for growth in the condition of a large temperature difference between day and night.
Characters of herbs: Spherical, oblate or irregular block, size, weight from 1 kg to more than 5 kgs. The surface is dark brown or brown, the outer skin is thin and coarse, with obvious raised wrinkles, often with soil. Weight, hard, not easily broken; Cross-section is not flat, show grain shape or powdery, the outer layer is light brown or pink, inside layer is all white, a few are a light brown, exquisite, and visible fissure or brown pine root and white fuzziness piece Mosaic is in the middle. No smell, chewing sticky teeth. With weight solid, outer skin shows brown and take burnish slightly, furrow is deep, section white is exquisite, stick tooth force strong person is beautiful. White tuckahoe all already cut thin slice or square, color white is exquisite and have pink slippery feeling. Crisp, easily broken, sometimes yellowish-brown edges.
Pharmacological actions: The decoction of poria cocos has sedative, anti-ulcer, prevent liver cell necrosis, protect the liver, increase myocardial potassium content, reduce kanamycin toxicity in ear damage, has an anti-tumor effect.
