[Yin Yang Water]
Also known as Shengshu Tang (Decoction of Raw and Cooked Water). It has a sweet and salty taste, is non-toxic. It is prepared by mixing newly drawn cold water with freshly boiled hot water evenly.
[Indications] Primarily regulates the Middle Jiao (Middle Burner) and aids digestion. For conditions involving phlegm-malaria or swelling caused by retained food and toxic/evil substances, where Huoluan (Cholera-like syndrome) is about to occur, immediately add salt to the water and drink one to two sheng (approx. 200-400ml).
