Paste is made through the process of soaking, decocting, concentrating, collecting paste and storing. 1.Soaking: Check the ingredients and pick out the gums and put them separately. After that, put all the other medicines into a clean casserole of comparable capacity, add appropriate amount of water to moisten the medicine to make it fully absorbed and swollen, and later add water to rise about 10 cm above the surface of the medicine and soak for 24 hours. 2.Decoction: put the soaked herbs on the fire and decoct them. First, use high fire, boil and then cook for about 1 hour on low fire, then turn to light fire to boil for about 3 hours; at this time, the juice is getting thick, the first juice can be filtered out with gauze, then add water to moisten the original dregs and then you can decoct on fire, the decoction method is the same as before, this is the second decoction, wait until the third decoction, the smell is thin, filter the juice and then discard the dregs (if the juice is still thick, you can also decoct again). Mix the juice from the first three decoctions in one place, let it stand and then precipitate and filter it, so that the less the dregs, the better. 3.Concentration: Pour the filtered juice into the pot, concentrate, first decoction with high heat to accelerate the evaporation of water, skim off the above froth at any time, so that the juice gradually thicken, and then further concentrate with low heat, while constantly stirring, because the juice becomes thick easily sticky bottom burn, stirring to the degree that the juice drops on the paper does not scatter, at this point can suspend the decoction, that is, after the concentration and the formation of clear paste. 4.Collection of paste: the gum medicine and sugar (icing sugar and honey is better) steam and melt, pour into the concentrated paste, then put on a small fire and slowly boil, while constantly stirring with a shovel, until the paste can be pulled into a flag or in the drip into a pearl (the paste drops into water to condense into a pearl and does not fall apart) can be. 5.Storage: After the paste is cooled, put it into a clean porcelain container, first without cover, cover the mouth of the container with clean gauze and leave it overnight, then cover it and put it in a cool place after it is completely cooled. In addition, while collecting the paste, you can put the powdered medicine very fine (such as deer antler powder, ginseng powder, pearl powder, amber powder, placenta powder), etc., into in the paste and smear it well. The juice can also be taken when decocting walnut meat, cinnamon meat, red date meat, etc. together as needed, and put them together when collecting the paste can give full play to their effects.
