There are two basic components in TCM: Acupuncture and Herbal Remedies. They have been used to successfully treat a wide range of physical, functional and emotional conditions. TCM also treats conditions that do not fall into a particular disease category, disorders that are inexplicable or un-diagnosable with Western medicine. TCM has been established as a primary form of health care for thousands of years in China, where TCM doctor's role is comparable to that of the physician. Today, TCM remains an integral part of the healthcare system in China, being offered alongside Western medicine. In the UK, TCM is considered as both complementary and alternative medicine. Alternative Therapy: People seek the treatment through TCM when they find that conventional western treatments do not work for them or if they just want a natural and safe way of healing, perhaps due to reasons like being tired of depending on the chemical drugs of conventional Western medicine and/or being worried about their harmful side effects. Some people find that their medical treatment is causing unwanted side effects, and others may be unwilling to rely on medication. Therefore, they would use TCM as an alternative.
