Acupuncture treats health conditions by stimulating "acu-points" found at specific locations on the surface of the body. Acupuncturists stimulate the acu-points by inserting very thin needles through the skin to produce physiological effects. Acupuncturists use these points to tap into a network connecting every organ and part of the body, provides balance, regulation, and coordination of physiological processes.. Pain and illness result when the flow of Qi through the body is disrupted or blocked. This can be caused by many factors including disease, pathogens, trauma/injuries, and medication (side effects), as well as lifestyle factors such as overwork, poor diet, emotional imbalance, lack of rest, and stress.. Stimulation of the appropriate acu-points through acupuncture treatments helps to restore sufficient, continuous, and even flow of Qi and other nutrients throughout the body, restoring health and balance to the body while relieving pain and other symptoms. Acupuncturists are the only licensed health care professionals in California who are required to be trained and tested for competency in prescribing herbal medicine.
