Eastern medicine practices have always placed a strong emphasis on prevention and treating diseases naturally whenever possible. Now, in many ways, Western medicine is catching up, particularly when it comes to utilizing tai chi moves to improve the mind, body and heart. A growing number of people around the world are now interested in traditional Eastern systems of healing — including Tai chi, yoga, acupuncture and meditation — due to mounting evidence that they can help prevent and treat many health problems such as arthritis, anxiety and chronic pain.
