Identification method of poria cocos

There are several ways to identify the authenticity of Poria cocos:

2, take a bite, the real sputum sticks to the teeth, and the fake sputum is similar to chalk. Some of them are stuck with glue, which is very brittle.

3, draw hard on the concrete floor, there will be no traces of real poria cocos. If there is a white line, it is fake poria cocos.
