This important acupuncture point in the body, used to treat a variety of conditions, is located on the ankle, midway between the medial malleolus and the achilles tendon. The meaning of the pinyin name of the point, Taixi, is often translated as either great ravine, great valley, or supreme stream. The point is indeed, located in a valley, between the large achilles tendon and the medial malleolus, the prominent bone on the interior of the ankle. Located on the major Yin Water meridian of the body, the Kidney meridian, it has a strong effect on many bodily functions involved with the fluids, along with its other main function, that of maintaining the structure/bones, with the low back being the central place of focus.

Kidney 3 is used to treat a variety of conditions that affect the kidney channel and organ systems, ranging from low back, heel and ankle pain, to fertility and gynecological issues, such as endometriosis, to the kidney's relationship in Chinese medicine to the lungs and breathing; so asthma, and the inability to take a full breath (the kidneys are thought to pull the Qi down from the lungs, in TCM theory, thus allowing for a full, deep breath).

Additionally, Kidney 3 can be very helpful on the emotional level, for anxiety and grounding, also insomnia, as the kidney organ system is most closely associated with the emotion of fear. The kidney meridian is also used to treat any adrenal-related imbalances, and this is one of the most powerful points on the kidney meridian, so can be used to help support adrenal function.

Kidney 3 is a wonderful point to use in acupressure techniques, and can be massaged on a regular basis to help with any of the above issues.
