Chocolate cysts are actually a type of endometriosis, which is a cystic hyperplasia of the endometrium into the ovaries. If the patient is also suffering from anemia or deficiency of qi and blood, she can take Agaricus biloba because it has a nourishing effect on blood and can correct the anemia. Ovarian cysts actually belong to stasis from the perspective of Chinese medicine. There are many causes of stasis, including cold condensation, liver depression, qi deficiency and phlegm-dampness, all of which may cause ovarian cysts. In fact, the majority of cysts in clinical practice are due to stasis caused by spleen deficiency and phlegm-dampness. If the patient has spleen deficiency and heavy dampness, it is not recommended to eat Agaricus blazei. If the patient does not belong to spleen deficiency, but has phlegm and dampness in the body, and at the same time has blood deficiency and anemia, he can eat Agaricus blazei.
