Zhiyin is a critical point for turning a malpositioned fetus, a function for which it is famously employed with moxibustion. As the Jing-Well point, it has a powerful effect on the opposite end of the channel, making it effective for clearing the head and eyes, treating conditions like headache, head heaviness, and eye pain. Its ability to connect the Bladder and Kidney channels also makes it useful for addressing issues of urination and seminal emission.
