First, soak the herbs. Usually, it needs to be soaked for 12 hours to make the medicinal materials fully absorb water. Only in this way can all the effective components in the medicine be absorbed.
Second, three fried. You can fry it in the pressure cooker at home for several times, and soak the medicine in water every time, without too much, because the medicine has absorbed enough water. First decoct until boiling, then simmer for 20 minutes, filter and take out the liquid medicine. At the same time, squeeze out the remaining liquid medicine with a flat bowl of appropriate size. Decoct the residue with cold water. This is repeated three times, and the liquid medicines are combined. Generally, in the third juice, the liquid medicine is very weak, and the residue is like bean curd residue. The whole decocting process usually takes 3 hours.
Third, concentrate the essence. After frying the "three juices", let it stand for precipitation, and then filter it with four layers of gauze for three times to minimize the impurities in the liquid medicine. The decocted liquid medicine can be put into a container with fast heat conduction, such as a steel pot, and boiled with strong fire, without stopping stirring, evaporation and concentration, and at the same time preventing overflow, so that it gradually forms a thick shape. It usually takes about 4 hours. After the medicine juice of Gao Xiao Fang is concentrated, its amount is generally about 65438 0 liters (depending on the size of the prescription), and it feels sticky and accompanied by resistance when stirring.
Fourth, feed and collect paste. Add Colla Corii Asini, Colla Cornus Cervi powder, Carapax Trionycis powder (or melted yellow wine), maltose, crystal sugar, honey, etc. Pour into the thick paste liquid medicine, and collect the paste with slow fire. If there are precious drugs such as ginseng and cordyceps in the prescription, it is necessary to boil them into thick juice or grind them into fine powder with low fire, and take them when collecting the cream. Homemade cream can also be "dripping into beads". If it is too thin and thick after cooling, you can put it in a pot and boil it to evaporate water. Finally, put the prepared ointment into a sealed container and put it in the refrigerator, and you can take it every day. Take one scoop every morning on an empty stomach for the first time, one scoop in the morning and one scoop in the evening after one week.
