Note: Most of the treatment of thirst disorders is based on the theory of Yin deficiency and dry heat, but clinical evidence of Damp-Heat is also not uncommon. In clinical practice, San Ren Tang and Da Yuan Drink combined with Bazheng San have been used to achieve better results. Bazheng San is from “Taiping Huimin Hodong Bureau Formula” and is a common formula for treating damp-heat gonorrhea. It consists of Che Qian Zi, Qu Mai, Bian Cao, Slippery Rock, Mountain Gardenia Seeds, Licorice, Mouton, Rhubarb, simmered, removed, cut, roasted, one catty each (500g each) into the heart of the lamp. It has the function of clearing heat and diarrhea, inducing diuresis and laxative. It is often used in damp-heat gonorrhea. The formula uses Qu Mai to clear heat and cool the blood, and Moutong to clear heat and lower fire; supplemented by Bian Cun, Che Qian, Slippery Rock, and Lantern Heart to clear heat and dampness, and to clear the orifice and promote lymphorrhea, and Gardenia and Rhubarb to clear heat and diarrhea fire and induce heat to go down; Licorice tip and medicine to slow down the urgency and stop astringent pain in the urinary tract. The combination of all the drugs, and have the function of clearing heat and fire, diuretic and laxative. Dajuan Drink, from “Plague Theory”, has the effect of opening up the membrane and removing filth and turbidity. It is used for treating plague or malaria, where the evil is in the membranes. Abhorring cold and strong fever, or three times a day, or once a day, with indefinite onset, chest tightness and vomiting, headache and irritability, pulse stringiness, deep red tongue, greasy tongue coating, or thick white coating like powder. This formula is designed for plague obscene and poisonous evils ambushed in the membrane. The “Revised Treatise on Common Typhoid” says: “The membrane is the membrane of the diaphragm; the original is the place of the gap. Outside the coup, near the stomach and internal organs, that is, the key to the three jiao, for the internal and external junction of the place, the real one half of the table and half.” The Plague Theory says: “The epidemic feels the plague of heaven and earth, …… evil from the mouth and nose, then its guests, not in the internal organs, not in the external meridians, shed within the brawn, not far from the table, near the stomach, is the boundary between the table and the inside, is half table and half inside, that is, the needle scriptures called ‘ The ‘horizontal connection to the membrane original’ is also.” The evil of plague enters the membranous Yuan half of the table and half of the lining, the evil and the positive compete with each other, so see the abhorrence of cold and strong heat; plague heat and poison invade the lining, resulting in vomiting, vomiting, headache, irritability, white moss thick as cumulus powder, and a bunch of filthy symptoms. At this time, the evil is not in the table, do not use sweating; heat in the damp, can not simply clear heat; damp in the heat, and avoid one-sided dry damp. When to open up the membrane original, to open up the filth and turbidity as the method. The formula uses betel nut, which is pungent and disperses dampness, resolves phlegm and breaks up knots, so that the evil can be quickly collapsed, and is the ruling medicine. Hou Pu aromatic turbidity, rationalization of Qi to dispel dampness; grass fruit pungent turbidity, remove obscenity and stop vomiting, and promote the penetration of voodoo, a total of ministerial medicine. The above three medicines are pungent and can reach the membrane and expel the evil. Where the evil of warmth and epidemic, most likely to turn into fire and hurt yin, so use white peony and Zhi Mu to clear heat and nourish yin, and prevent the pungent and dry drugs from dissipating yin and fluid; scutellaria baicalensis is bitter cold, clearing heat and drying dampness, together as an adjuvant. It can clear heat and detoxify the body and harmonize all medicines. The whole formula, together, can open up the membrane, remove filth, clear heat and detoxify, so that the filth can be dissolved, heat and toxicity can be cleared, and yin and fluids can be restored, so that the evil gas can be dispersed and quickly leave the membrane. Wu also can “warm epidemic theory” on the volume: “betel nut can eliminate can grind, in addition to volatile evil, for the dredging of the medicine, and in addition to the Lingnan miasma; thick park break hostile gas knot; grass fruit pungent strong gas male, in addition to volatile evil coiled, the three flavors work together, straight to its nest, so that the evil collapse, quickly away from the membrane, is also thought of as da yuan. If heat hurts fluid, add Zhi Mu to nourish Yin; if heat hurts Ying Qi, add Bai Shao to harmonize Blood; Scutellaria Baicalensis to clear the residue of dry heat; Licorice to harmonize the middle. The next four products are the agents of reconciliation, such as thirst and drink, not the medicine to pluck the disease.” Keywords: diabetes mellitus, thirst, halitosis, salivation, damp-heat evidence, Chai Scutellaria da Yuan Drink combined with Bazheng San
