Master Tung’s acupuncture point 11.25 Zhi Xian 【止涎】”Stop drooling”
The name of this point is stop drooling, meaning it can adsorb or astringe discharge. We can understand it since this point is on the Tai yin lung meridian which is correspondence with the contractive nature of autumn.
Location: A three point set on the dorsal aspect of the thumb, along the radial border of the proximal phalange. Divide the line into four equal parts, the points are located in the junctions of each quarter. Some doctors will locate and puncture two or even five points in this area. I usually use two or three points distributing them equally.
Needle: 0.2-0.3 cun, or let out blood. We can puncture from dorsal to palmar or threading them all together from distal direction to proximal.
