Renzhongbai is a traditional Chinese medicine, which can also be called Baiqiu cream, human urine white, and protein base. It is a solid substance formed by the natural deposition of healthy human urine over a long period of time, which is considered cold in nature and has medicinal value by Chinese medicine practitioners. The urine scale that condenses on the sidewalls of urinals and buckets is removed, impurities are removed, dried and finally concocted into a medicinal herb, usually in the form of irregular flakes of varying sizes. Studies have shown that it contains calcium phosphate, calcium oxide, calcium urate, calcium oxalate and many trace elements, and is considered by Chinese medicine to be effective in clearing away heat and toxins, stopping bleeding and stasis, and reducing swelling and pain. Since Ren Zhong Bai is not suitable for use alone, it is usually used clinically in combination with other herbs, i.e. the drug is ground and applied to the affected area, and can be used to treat diseases such as mouth ulcers, red and painful gums, dermatitis, burns, tongue and mouth sores, thrush, etc. It can also be decocted with honeysuckle to relieve sore throats. In addition, from the perspective of modern medicine, Ren Zhong Bai has some auxiliary effects in the prevention and treatment of diabetes and aging. However, it should be noted that the coagulated urine scale needs to be thoroughly disinfected before use, otherwise it may easily cause bacterial infection. At the same time, the composition and dosage of Ren Zhong Bai is not yet fully clarified, and it can be used orally or externally to relieve the disease. If you need to use Ren Zhong Bai, you need to clarify the contraindications and the combination of contraindications, and do not make it for private use, such as internal heat, Yang deficiency without fire or indigestion patients need to avoid the application. Therefore, if it meets the indications for use, it can be applied to drug therapy under the guidance of a doctor to achieve better therapeutic results.
