Acupuncture, an ancient form of traditional Chinese medicine, works on the principle of stimulating points in the body to balance the flow of energy (Qi). Traditional Chinese medicine recognizes the mind and body interacting as one and believes emotions have a physiological effect on the body.

   Anxiety relates to an imbalance of the heart and kidney, according to Chinese traditional beliefs. Too much heat in the heart will imbalance the interaction with the kidney and acupuncture on points around the heart, kidney, spleen and ear are used to treat anxiety. A study published in the Journal of Endocrinology discovered stress hormones were lower after receiving acupuncture.

   Depression is considered to be a problem with circulating Qi around your body, according to traditional Chinese beliefs. The main organ responsible for circulating Qi is identified as being the liver with the heart and spleen as well.
