The difference between raw gypsum and cooked gypsum lies in the efficacy and treatment as well as the usage. 1. Efficacy: Gypsum can clear away heat and fire, promote the production of fluids to quench thirst, and eliminate vexation. For example, in Baihu Tang, it is combined with Zhimu to treat strong heat, thirst and sweating. Combined with xuan shen, it can treat warm diseases with delirium tremens (confusion, babbling) and strong fever. In addition, it can also be used with almonds and ephedra to treat lung-heat cough and asthma. Simplified gypsum can collect dampness, stop bleeding, astringent sores and regenerate muscle (help sores heal faster and promote the growth of new flesh). It can be combined with red powder and applied to the affected area to help heal ulcers. It can also be mixed with cypress and applied externally to treat wet sores and itching. If treating water and fire burns, it can be combined with Qingdai. In addition, it can also be used to treat traumatic bleeding. 2. Usage: raw gypsum is usually taken internally, cooked gypsum is usually used externally. If you need to use the medicine, please apply under the guidance of a physician.
