Mining and processing of wild Poria cocos

Mining during the period from the Beginning of Autumn to the Spring Equinox is the best. If the land is excavated blindly, it is laborious and time-consuming, and it is not conducive to soil and water conservation, so it should be excavated scientifically.

Poria cocos growth place has the following characteristics: ① special near the ground cracks, knock issued a hollow sound; ② soil dry pine, after light rain around the residue drying faster; ③ residue near the grass does not grow or sparse. The specific mining method is: select a special steel rod with a length of about 60cm and a diameter of about 0.6cm, and open a small groove after the bit, and knock it into the ground about 20~40cm depth. If it is more difficult to pull out the steel bar or the steel bar trough is covered with Poria cocos pine pulp, you can dig under the hoe at this time.

The Poria cocos dug back by processing should be brushed away from the soil (not suitable for washing) and placed in a cool and unventilated place. First spread a layer of straw, and then stack Poria cocos and straw layer by layer, sealed with straw all around, and the top layer covered with thick sacks to make it "sweaty". 6 after 8 days, if white villi (hyphae) grow on the surface of Poria cocos, it is "sweating" success (if no mycelium grows, it is necessary to continue sweating). After taking out, dry the water droplets, brush off the white hyphae, spread them out in a cool place, sweat repeatedly for 3 or 4 times after the surface is dry, until the surface shrinks, the skin color turns brown, and leave it in a cool and dry place to dry.
