What is the latest Poria cocos?

Poria cocos, commonly known as poria cocos, poria cocos and poria cocos, is a fungus plant parasitic on the roots of pine trees. It is shaped like sweet potato, with dark brown skin and white or pink inside. Its original organism is the dried sclerotia of poria cocos, a fungus of Polyporaceae. It is mostly parasitic on the roots of Pinus massoniana or Pinus densiflora. It is produced in Yunnan, Anhui, Hubei, Henan, Sichuan and other places. More than 7~9 months to dig, dig out after removing sediment, pile up "sweating", spread out to dry the surface, and then "sweating", repeated several times until wrinkles appear, most of the internal moisture loss after drying, called "Poria". Or cut fresh Poria according to different parts, dried in the shade, respectively known as "Poria block" and "Poria tablets."

Poria cocos mycelium includes two kinds of mycelium, monokaryon and binucleate mycelium. Monokaryon mycelium is also called primary mycelium, which is formed by spore germination of Poria cocos cocos and exists only in the initial stage of germination. Dikaryon mycelium is also called secondary mycelium, which is the main form of mycelium. It is formed by the meeting of two monokaryon mycelia of different sexes and after mating. Mycelium appearance was white villous, with a unique multi-concentric ringed colonies. Under the microscope, it can be seen that the mycelium is composed of many branched hyphae. The hyphae are divided into linear cells by diaphragm, about 2~5 microns wide, and lock-like association is often seen at the top.

Poria sclerotium is a dormant body formed by a large number of hyphae and nutrients closely gathered, spherical, ellipsoidal, oblate or irregular block, weighing two small, several jin, dozens of jin, soft when fresh, easy to break open, hard after drying is not easy to break open. Sclerotia outer shell, rough surface, tumor-like shrinkage, pale brown or tan when fresh, dry into dark brown, white and pale brown skin. Under the microscope, the white part of sclerotia hyphae showed lotus root node shape or extruded lump shape. Near the skin are slender and densely arranged pale brown hyphae.

The fruiting body of Poria cocos is usually produced on the surface of sclerotia, occasionally found on the older mycelium, honeycomb-like, variable in size, sessile and procumbent, about 0.3~1 cm thick. White at first, lignification turns pale yellow after aging. The sporangium is attached to the inner wall of the pore tube and consists of numerous basidia. Each mature basidium produces four spores (basidiospores). The spores of Poria cocos are pale white, oblong or nearly cylindrical, with an oblique tip, 6×2.5~11×3.5 microns.

tuckahoe is sweet and mild in nature, enters the heart, lung and spleen meridians, has the effects of permeating dampness and diuresis, invigorating the spleen and stomach, calming the heart and tranquilizing the mind, and can cure dysuria, edema and fullness, phlegm and cough, vomiting, aversion, diarrhea, nocturnal emission, turbidity, palpitation, amnesia and other diseases. the ancients called tuckahoe a "four-season divine medicine" because it has a wide range of effects, regardless of the four seasons. it can be combined with various medicines to exert its unique effects regardless of cold, warm, wind and dampness.
