What is the black paste matrix

Black paste is semi-solid or solid at room temperature, and when applied, it is heated so that the paste is slightly melted, mainly for external paste, black paste is one kind of paste of external treatment method of motherland medicine, and the use of black paste to treat the disease has a history of nearly 1,000 years in our country.

The black ointment, also known as lead ointment, is made of vegetable oil, medicine and lead dan. Black ointment process will be oil, Dan made of a certain proportion of substrate, and then the crude material extracted by boiling, concentrated into a thick paste or extracted by deep-frying into the production of medicinal oil, fine material and the need to maintain the medicinal properties of raw drugs pressed into a fine powder, spreading the paste will be a thick paste and fine powder to method to the heated melting (to remove all the water) of the substrate, stirring to remove all the water after spreading the paste. "Boiling method of extraction production process" to maintain the full composition of the drug, reduce the loss of active ingredients in the high-temperature boiling decomposition of herbs, reduce costs, easy to produce; high-temperature-resistant drugs can be extracted using the frying method, the following all the prescriptions have been specified extraction method.

Selection of raw materials for black ointment matrix and treatment of medicinal materials

1. Vegetable oil: hemp oil with pure texture is good. Its advantage is that when refining less foam, conducive to operation. And made of ointment color bright, sticky, good quality. Can also be used cotton oil, rapeseed oil, peanut oil, etc., should not use soybean oil.

2. Huangdan: also known as chapter Dan, lead Dan, red Dan, Tao Dan, orange-yellow, heavy, powdered, the main become four lead oxide, purity requirements in more than 95%. (Can be bought in large pharmacies or chemical stores)

3. Treatment of medicinal materials: medicinal materials can be divided into general medicinal materials (coarse materials) and fine materials of two categories. Coarse material for general Chinese medicine roots, stems and leaves, fine material for the precious medicine and aromatic medicine. Coarse material according to the prescription to take a good, and appropriate crushing, for boiling withered slag preparation.

Fine materials, such as musk, etc. into a fine powder standby, spread on the surface of the paste; soluble or volatile fine materials, such as ice chips, camphor, myrrh, frankincense, etc. can be studied as a fine powder standby, put into the melting of the paste in the mixing before spreading.
