Introduction to Specific Herbs

Some herbs, due to their properties, flavors and channel tropism, have specific effects on relieving pain. This section focuses on such herbs. 

Is it good enough to rely on them simply based on their warm property, pungent flavor, or tendency to work on liver channel, for example? In my opinion, it is the tendency of these herbs 'floating up' and acting on different locations on head that qualifies them to be headache specific herbs.

Headache in the forehead and supra-orbital bone is due to the disorder of the yangming channel, we may use Dahurian Angelica Root; headache in both sides of the head, especially in the temples, due to the shaoyang channel, uses Bupleurum Root; pain the back of the head and the neck, due to the disorder of the taiyang channel, uses Notopterygium Root and Chuanxiong Rhizome; headache in the vertex of the head, due to the trouble of the jueyin channel, uses Evodia Fruit.

Bear in mind that the usage of specific herbs is not rigid. One should be flexible and adaptive in prescribing formula based on prescription principles of TCM.
