Herbal medicine is one of the primary branches of Chinese Medicine.  Classical herbal formulas are often used in conjunction with acupuncture in order to enhance overall treatment results.  More than 300 herbs that are commonly used today have a history of use that goes back at least 2,000 years.  Classically, raw herbs would be boiled into tea form for consumption.  In modern times, raw herbs are often concentrated into granular form or tea pills, which makes for easier administration.
