Decocting method, decocting method and formula of black plaster

1, select Paste. Black plaster is mainly divided into ointment and medicine. Before making, you usually need to choose sesame oil, and then you can add Huang Dan appropriately. Be careful not to choose soybean oil and try not to choose other oils. Sesame oil and sesame oil are generally better choices.

2. Choose medicinal materials. Making plasters with different effects requires different medicinal materials, and the collocation between medicinal materials is more important, which can be completed according to specific formulas. Then all the medicinal materials need to be processed into powder, and the finer the infiltration, the better the effect will be.

3. Explosives. In the process of making black plaster, you need to heat it a little, then put all the medicinal materials in it and stir it evenly until the medicinal materials turn yellow-brown, and then you can clean the residue.

4, frying oil. After taking out the dregs, we should continue to refine them. At this time, turn down the fire and then heat it to 320 degrees with a big fire. Generally speaking, it is better to drop water into beads.

5, practice cream. Lead can be properly added to oil at high temperature, and lead will generate fatty acid lead salt through chemical reaction, which will promote the oxidative polymerization of oil and become paste after a series of changes. Finally, it is necessary to put the refined plaster into clear water and stir it evenly in one direction until it becomes paste completely. Then you need to soak for 3~7 days, and you need to pay attention to changing the water every day.
