Traditional Chinese Medicine (TCM) is over 3,500 years old and one of the most widely practiced healing systems in the world. TCM believes that 20 pathways, called meridians, connect up to 2,000 acupuncture points across the body. These meridians conduct energy, or “qi” (pronounced “chi”), between the surface and internal organs. Qi is thought to regulate balance in the body, influenced by the opposing forces of yin and yang—representing positive and negative energies.
