【Indication】 |
This formula is indicated for intense heat in the heart channel. The symptoms are vexing heat in the chest, sores in the mouth and tongue, thirst, red complexion, preference for cold drinks, difficult and painful urination that is dark, a red tongue, and a rapid pulse. |
【Pathogenesis】 |
This is a pattern of intense heat in the heart channel or the transmission of heart heat to the small intestine. The heart fire flames up along the channel and causes vexing heat in the chest, sores in the mouth and tongue, and a red complexion. The intense fire consumes yin, which causes thirst and a preference for cold drinks. Since there is an interior-exterior relationship between the heart and the small intestine, heart heat transmits to the small intestine, which fails to separate the clear and the turbid and cause difficult and painful urination with dark urine. The red tongue and rapid pulse are signs of internal heat. Qian Yi said the pathogenesis of this pattern is “heart heat” or “heat of the heart qi”, without defining the nature of the pattern in terms of deficiency or excess. Later, the《Golden Mirror of the Medical Tradition》Yi Zong Jin Jian concluded this pattern is “deficient water without excessive fire”; in other words, the yin deficiency and the fire are not severe. Children, whose yin and yang are tender, are more apt to contract cold and heat. Their diseases change rapidly, and may be either deficient or excessive. According to these features, Qian Yi established the therapeutic principle: prevent deficiency when treating excess, and prevent excess when treating deficiency for children’s diseases. Since the flaming of heart fire damages kidney yin, Qian Yi also suggested clearing heart fire together with nourishing yin, and promoting urination to drain heat. |
