TCM understands the body by using several forms of evaluation. One of the tools used for evaluation is detailed pulse-taking where the practitioner discerns the qualities of the pulse to check for imbalances in the body. Analyzing the form and condition of the tongue, face, ears and feet is also used to assess health deficiencies. Over the centuries, TCM has been used to treat even subtle health imbalances before physical problems can occur. Today, Chinese Medicine uses acupuncture, herbal medicine, massage, exercise and breath therapy, diet and lifestyle counseling to regain balance and improve a variety of health conditions.
