An example of a relative excess of Yang over Yin is the low-grade fever and night sweats associated with menopause. Over the course of a woman's life, she may consume her Yin in ways both natural (childbearing, menstrual bleeding) and unnatural (relating to her lifestyle, such as smoking, over-consumption of spicy foods, not getting enough sleep). In this state, even if her Yang is at normal levels, her deficient Yin will show up as Heat, or a relative excess of Yang. In this case, the treatment principle would likely be to nourish the Yin, which is deficient, rather than sedating the Yang, which remains at normal levels.
