Night sweating is a sign of yin deficiency, and moxibustion is not appropriate for yin deficiency and fever, which is a sign of deficiency heat. Therefore heat conditions are not suitable for moxibustion whether they are signs of solid heat or signs of Yin deficiency fever. It is not possible to immerse heat with heat, that is, heat illnesses cannot be treated with heat medicines as well as heat methods. Therefore, moxibustion is not suitable for night sweating, but acupuncture can be used to clear deficiency heat and stop night sweating. Acupuncture is usually used to nourish kidney water and clear deficiency heat at the points of Fuxiao, Hegu and Yin Qie.
