Let me tell you what "heart-kidney intersection" is: "heart-kidney intersection" is a physiological phenomenon between heart and kidney based on yin-yang theory and the rise and fall of fire and water. The five elements of the heart belong to fire, the five elements of the kidney belong to water, and the yin is below. According to Yang Ming's theory of the rise and fall of fire and water, Yin and Yang must intersect, that is, fire and water, so it is called "fire and water ji ji". Therefore, it is considered that the kidney water below will rise and the heart fire above will fall, so as to realize the "ji ji of fire and water" and "intersection of heart and kidney" and coordinate and balance the physiological functions between heart and kidney. Then the heart and kidney don't cross: "the heart and kidney don't cross" is a pathological state between the heart and kidney based on the theory of yin and yang and the rise and fall of fire and water, that is, the kidney water is insufficient to benefit the heart and make the heart fire flourish alone; Or the heart yin is insufficient, the heart fire is strong, and the kidney yin is pulled down, resulting in insufficient kidney water; Or the heart fire can't reach the kidney, which leads to the coagulation of kidney water and can't benefit the heart. In short, if the normal physiological state of "heart and kidney intersect" is destroyed, there will be a pathological state of "heart and kidney do not intersect", that is, there are two kinds of pathologies that lead to the disharmony between heart and kidney. One is kidney deficiency or heart fire, which may exist at the same time, while both kidney yang deficiency and kidney yin deficiency exist in one form. Liuwei Dihuang Pill is used for kidney deficiency due to heart-kidney disharmony, Niuhuang Qingxin Pill and Sanhuang Tablet are used for getting angry. Use Liudihuang Pill for kidney yin deficiency and Jinkui Shenqi Pill for kidney yang deficiency! But if you don't give your heart and kidneys, you should go to the hospital to see a doctor.
