The practice of Chinese herbology is older than the practice of acupuncture. The Chinese Materia Medica includes hundreds of herbs that have been used for thousands of years. The therapeutic use of each Chinese herb is determined by the herb's specific properties and by the herb’s ability to influence certain meridians or organs. Herbs are seldom taken individually. Typically, eight to twelve herbs are combined into a formula designed to adjust each patient’s unique chi imbalances. The use of Chinese herbs and the combination of these herbs into classical formulas have been based upon centuries of empirical observation and clinical experimentation that have been recorded since at least 1066 BCE.

Herbal formulas may be dispensed in tablets, granules (powder mixed with warm water), or as raw herbs (boiled to make a tea), and are relatively low in cost. Formulas are typically taken two or three times per day.
