Brain cancer is a heterogeneous disease, with astrocytoma and glioblastoma being the most predominant among all brain cancer types. In TCM, brain cancer refers to a disease that primarily grows in the skull and presents symptoms such as headache, cranial tinnitus, syncope, and paralysis. TCM defines 14 channels in the body among which three foot and three hand Yang channels meet on the top of the head, which is referred to as “the joint of the hundred channels.” The location of the head is high on the body and belongs to Yang, whereas the brain belongs to Yin. If the Yang Qi is vigorous, evil Yin would not be able to invade it. However, if healthy Qi is deficient, the evil Yin will attack the head and brain collaterals, which are called “the double Yin.” Headache, vertigo, nausea, and syncope then can occur.
