Disease and Condition Overview
Hyperhidrosis is characterized by spontaneous and excessive sweating without taking any transpiration drug, heavy exercise, or under hot weather. It is most often seen m children with weaker body constitution. In Chinese medicine, it is caused by disharmony of defensive and nutritive qi, spleen and lung qi deficiency, excess stomach heat, leading to weakened defensive qi, unable to retain fluid. Clinical symptoms include constant sweating, especially after exercising, pale face, cold limbs, shortness of breaths and sensitive to cold and wind. Other symptoms may include those exhibited in sympathetic nerve disorder as well.

Pair-point Treatment Combinations

(1) Erjian (LI 2), Yinxi (HT 6) (Fig 94)
Erjian (LI 2): on the radial side of the index finger, in the depression distal to the second metacarpo-phalangeal joint on the radial side. Slightly clench fist to locate the point.
Yinxi (HT 6): on the palmer side of the forearm, on the radial side of the tendon of the flexor carpi ulnaris, 0.5 cun proximal to the wrist crease.
Erjian (LI 2) reduces heat and removes stagnation. Yinxi (HT6) clears fire and strengthens the exterior. This pair point combination, one reduces while one clears, clears heat, reduces fire, release the exterior and stops sweating. Appropriate for hyperhidrosis caused by excess inner heat.

Needling techniques:
1. Erjian (LI 2) perpendicular insertion 0.5 cun.
2. Yinxi (HT6) perpendicular insertion 0.5 cun.

(2) Hegu (LI 4), Fuliu (K 17) (Fig 71)
Hegu (LI 4) clears heat, strengthens exterior, opens and dredge intestine harmonizes stomach. Fuliu (KI 7) tonifies kidney, nourishes the parched, induces water, and reduces swelling. This pair point combination, one tonifies while one reduces, strengthens exterior and induces water, regulates and harmonizes skin and the zang fu organs. Appropriate for hyperhidrosis caused by yang deficiency and excess dampness.

Needling techniques:
1. Hegu (LI 4) perpendicular insertion 1 cun, use tonify method
2. Fuliu (KI 7) perpendicular insertion l cun, use reducing method.

Commentaries
For hyperhidrosis caused by qi deficiency or yang deficiency, whose symptoms include shortness of breathes and feeling weak and fatigued, sensitive to cold, select Hegu (LI4), Fuliu (KI7). In terms of needling, tonify Hegu (LI4), reduce Fuliu (KI7).
Other type of hyperhidrosis patients usually exhibit signs of intolerance to heat, excessive sweating under slight higher temperature is a sign of excess inner heat. Select Erjian (LI2). Yinxi (HT6).
It is important to recognize that hyperhidrosis patients usually have excess water and dampness, more susceptible to heat and cold.
