Chinese herbal medicine is a complex and refined system for combining plant, mineral and sometimes animal substances into formulas that will address many different patterns of disharmony.  Because herbal formulas existed for millennia before antibiotics and drugs, there are many herbs that can treat common ailments such as colds/flu, as well as asthma, sinusitis, GERD, and constipation.  Each herbal formula is designed to respond to the unique pattern that is exhibited by each patient.  Because the pattern is being addressed (rather than the effects of the pattern), the same formula can be used for headaches in one patient, and red eyes with nosebleeds in another patient.  Chinese herbal substances are generally very safe and effective, but should not be taken indefinitely and need to be administered by a trained herbalist.
