As the Jing-Well and Wood point of the Spleen channel, Yinbai is a primary point for stopping bleeding, especially uterine bleeding from Spleen Qi deficiency, for which it is famously effective with moxibustion. Its ability to restore consciousness makes it a key point in first aid for collapse or fainting, particularly from deficiency patterns. It also treats acute digestive upsets like vomiting and diarrhea by regulating the Spleen's function in the middle jiao.
