It is possible to do moxibustion at the Sanyinjiao to make it feel cold all the time. Sanyinjiao is the meeting point of the foot Taiyin-Spleen meridian, the three yin meridians (liver, spleen and kidney) of the foot, Sanyinjiao is located in the lower limbs of the inner ankle tip about three inches straight up, the position of the posterior edge of the tibia. Sanyinjiao can be used to treat gynecological disorders such as irregular menstruation, metrorrhagia (excessive menstrual flow or dribbling), as well as digestive disorders such as indigestion, diarrhea, vomiting and flatulence. When the Sanyinjiao feels cold, it may be due to kidney deficiency or Qi deficiency, which can usually be relieved by using moxibustion. Moxibustion uses moxa leaves as the main ingredient, which is warm and enters the liver, spleen and kidney meridians, warming the meridians and opening up the veins, which is effective in treating coldness. However, it should be noted that the skin at the Sanyinjiao is relatively thin, so moxibustion should be carried out to prevent burns. And if the Sanyinjiao often appear cold, should also go to the hospital in time to clarify the specific causes, to avoid missing the best treatment time.
