In Traditional Chinese Medicine (TCM), diseases are often treated with herbs as well as acupuncture. Application of Chinese herbs in treating diseases is based on the nature and activities of herbs and herbs are depending on the energies, flavors, movements, and meridian belongings of the herbs. For example, there are four energies of the herbs: cold, hot, warm, and cool. When an herb is effective in the treatment of a hot syndrome, it is considered to have a hot energy. The four energies can be further divided into yin and yang in Chinese medicine. Cold and cool energies belong to yin and hot and warm energies belong to yang.
