Ointment: Ointment, also known as ointment and decoction, is a semi-fluid colloidal body formed by concentrating water or alcohol solution of drugs. It was called "decoction" in the Tang Dynasty, and it was used to be called "paste" or "paste" after the Ming and Qing Dynasties.
In fact, the cream is to boil a lot of medicinal materials at a time, then concentrate them to a certain extent, with or without honey, and take them several times after concentration. It reduces the trouble of decocting medicine every day, saves time, and has good taste and convenient administration. The production method is simple:
First, break the medicinal materials, soak them in water or wine for half an hour, then heat and decoct, filter out the juice, and repeat for 2-3 times until all the soluble substances in the medicine are dissolved to a certain extent. Then, the filtrates were combined, slowly evaporated and concentrated on low fire to form a paste. At this time, glue or fine medicinal materials that need to be melted can be added, and appropriate amounts of crystal sugar, maltose and honey can be added to the medicinal juice according to personal conditions, and xylitol can be added to diabetics. Boil and cool. Use porcelain pots and bowls, and it is best to keep them in vacuum bags if possible.
