How long does moxibustion at Yin point have effect?

Accurate moxibustion is generally recommended. This acupoint fumigation moxibustion only focuses on moxibustion. Of course, if you keep it, you can moxibustion at an acupoint for about 30 minutes.

As for the effect, I don't know what your problem is. Generally, moxibustion lasts for 10 days, then moxibustion is stopped for 1 2 days, and then it is continued for 10 days until it gets better.
