It’s late autumn again, and many rheumatism patients are weak due to illness and medication, and need to take tonic. And many patients are intolerant to ginseng and deer antler as well. I think Colla Corii Asini is a good choice. Colla Corii Asini, also known as Donkey Skin Colla Corii Asini, is mainly produced in Shandong and Zhejiang, but it is also produced in Shanghai, Beijing and Tianjin, but Dong’a County in Shandong Province is the best. It is made from good black donkey skin in winter, and the water from the well of Yuejiazhuang Xi’a in Dong’a County. This is why it is called Colla Corii Asini. How to take Colla Corii Asini? Take 250 grams of Colla Corii Asini, wash it with water, put it in a covered ceramic container, soak it in 500 grams of yellow wine (reduce the amount of yellow wine if you are weak and firey), then put in the right amount of rock sugar, store it for about two weeks until the Colla Corii Asini dissolves, then add tonic products according to each person’s condition, such as sore back, weakness, kidney deficiency, add fried walnut meat and black sesame seeds, black dates (remove the core) and other kidney tonic products; If the face is yellowish, dizziness and heartbeat, anemia and insomnia, women with blood deficiency symptoms such as leakage, excessive menstruation, etc., add longan meat, red dates (remove the kernels) and other blood tonic products. After melting the gum add the above products, can be stewed over a hydrological fire, stirring appropriately, about 2-3 hours until the gum completely dissolved, cooled in the form of frozen gum, can be taken. Generally, from the winter solstice to spring, 1-2 spoonfuls can be taken every morning on an empty stomach with boiling water, which is the most convenient homemade poultice in winter. Of course, if necessary, it can be taken regardless of the season, see the deficiency on the tonic, as long as the body needs, can be taken throughout the year.
