Why would one use lower He-Sea points, what are the indications?
According to Van Nghi
Co, SI and TH are the three arm yang and their He-Sea points are located around the elbow, far away from their associated Fu. These points have little or no effect in treating pathologies of their organs which are instead strongly affected by points called lower He Sea points (xiahe) of Co, SI and TH – the first two on the St meridian (the St in CM encompasses the all abdomen) the third on the BL. They are
- ST37 – has a direct action on the Co in case of excess and deficiency, has an action on the entire GI tract and treat Qi pathologies of the upper region of the body
- ST39 – has a balancing action on the SI in case of excess and deficiency, treats problems of the lower region of the body (oedema of the legs)
- BL53 – has a balancing action on the yang defensive Qi produced by the TH (point name: wei yang – supporting yang). In the NeiJing is written that “when TH is empty there is incontinence, when the TH is full there is anuria” and consequently we must tonify in case of deficiency and disperse in case of repletion. Therefore, BL53affects all the physiological fluids.
