Herbs that Regulate the Qi 理气药《神农本草经》

Overview

The dried root of aucklandia, heavy with aromatic oil and identifiable in a dispensary by smell alone. Acrid, bitter and warm, it is the reference herb for moving qi in the middle and lower abdomen — distension, griping pain, the urgent unproductive straining of dysenteric disorders. Because it also keeps rich tonics from clogging the digestion, small amounts are added to tonifying formulas for that reason alone. Its action lives in the volatile oil, so it goes into a decoction near the end rather than being boiled from the start.

Cautions

Aromatic, warm and drying, so it consumes fluids: it is used carefully — or with moistening partners — where there is yin deficiency, blood dryness or clear heat signs. Boiling it long destroys what makes it work, so it is added at the end of cooking.
