Chinese herbal medicine is a complex system that involves crafting a combination of herbs to treat the patient's specific needs. Anywhere between 12 and 20 herbs are combined and tailored to fit the patient’s condition. These formulas are dispensed in different forms, such as pills, tinctures, powders, or raw herbs that need to be cooked by the patient (cooking service is available for patients who do not wish to be bothered with the preparation process). The formulas for the herbal supplements are, much like most other aspects of TCM (Traditional Chinese Medicine), thousands of years old and were proven effective time and again.
