Tok Sen Healing Harmony, or Chi Nei Tsang III, is the technique to clear blocked energy. Originally it was called Sen Sip in the Thai system of massage, which was used for numerous functions, including healing and maintenance of a healthy body. The unique and special feature of this treatment is the emphasis on the ten major energy channels. These “wind” channels are related to those found in Chinese medicine. There is also a relationship to traditional acupressure.
