[Prescription]
This prescription is mainly used to treat internal water-dampness, weakened bladder qi transformation function, resulting in thirst, vomiting when water enters, difficulty in urination, and symptoms such as headache fever due to unresolved exterior syndrome/pattern. Because the exterior pathogen is not resolved, it circulates externally through the great yang meridian and internally through the great yang bladder internal organs, resulting in unfavorable bladder qi transformation, and water accumulation in the lower energizer causes two diseases of the great yang meridian and fu organs. Therefore, it causes headache, fever and floating pulse on the outside, and difficulty in urination on the inside. Water storage lower energizer, body fluids cannot be transported, so polydipsia requires fluid retention, which is called "water storage" syndrome; if water stops in the stomach, vomiting will occur when water enters, which is called "water counterflow ” syndrome; spleen deficiency means bad luck, the spleen cannot control water, and water and moisture overflow the skin, so edema is heavy in the body; water injects large intestine, so diarrhea. The general reason is that fluid retention is caused by water accumulation, so use Poria, Polyporus, Alisma, dredging and regulating water passage, and diarrhea. White Atractylodes Rhizome invigorating spleen and drying dampness; the four medicines used together have the effect of removing dampness and diuresis; Cinnamon Twig can warm the yang qi and enhance the function of the bladder. The qi transformation function makes urination easier; it can also relieve exterior syndrome/pattern such as headache and fever, and promote the full effect of promoting urination and draining dampness drugs. Therefore, the therapeutic effect of this prescription is to transform the bladder qi to dilute water, move the spleen yang mechanism to control water, transport fluid to the skin and hair to induce sweating, and steam the fluid to the mouth and tongue to quench thirst.
