There are many methods for preparing medicinal liquor. To sum up, there are the following commonly used methods at present: cold soaking method: cold soaking method is the simplest, especially suitable for preparing medicinal liquor at home. When using this method, the processed thin slices or coarse particles of Chinese medicinal materials can be placed in a sealed container (or the medicine can be filled in a silk bag first and then put into the container), and an appropriate amount of Chinese liquor (added according to the formula ratio) can be added, soaked for about 14 days, and shaken frequently, and the liquid medicine can be filtered out after the effective components are dissolved in the wine; The residue can be squeezed, then the leaching liquid and the squeezed liquid are combined, and the residue can be left standing for several days and then filtered. Or divide the Chinese liquor into two parts, soak the medicinal materials twice, and the operation method is the same as before, combine the leaching solution and squeezed solution twice, stand for several days, and filter to obtain clear medicinal liquor. If the prepared medicinal liquor needs to be flavored with sugar or honey, the white sugar can be dissolved with the same amount of white wine, filtered, and then the liquid medicine and the sugar liquid are mixed evenly, and then the medicinal liquor can be obtained after filtering.

hot soaking method: hot soaking method is an ancient and effective method to make medicinal liquor. Usually, Chinese herbal medicines are boiled with wine for a certain period of time, and then stored in cold storage. This method can not only accelerate the leaching speed, but also make the effective components in Chinese herbal medicines easier to leach. But when cooking wine, we must pay attention to safety, not only to prevent alcohol from burning, but also to prevent alcohol from volatilizing. Therefore, indirect heating method can also be used. This method is suitable for making medicinal liquor at home. The method is as follows: Chinese medicinal materials and wine are first put in a small casserole or an enamel pot, and then stewed in another larger water pot for a long time to avoid alcohol volatilization. At this time, it can generally be removed from the fire when foam appears on the powder surface, sealed while it is hot, and filtered to remove slag after standing for half a month. In industrial production, the coarse crushed Chinese medicinal materials can be wrapped in gauze, suspended in Chinese liquor, placed in a sealed container, soaked in a water bath at a low temperature of 4-5℃ for 3-7 days, or soaked twice, and the obtained product can be obtained by combining the extracts, standing for a few days and filtering. In addition, it can also be extracted by reflux method in laboratory or production workshop, that is, a reflux cooler is added above the soaking container to keep the mixture of soaked medicinal materials and wine slightly boiling, and the reflux time is determined according to different Chinese medicinal materials and different alcohol degrees. Cooling after reflux, and filtering.

decocting method: In this method, all Chinese medicinal materials must be crushed into powder, put into a casserole, add water until the medicine surface is about 1 cm, soak for about 6 hours, then heat and boil for 1-2 hours, after filtering, decoct the residue with appropriate amount of water once, combine the two liquid medicines, stand for 8 hours, then take the supernatant and heat and concentrate it into a paste. After cooling, add the same amount of wine, mix well, put it in a container, and put it in a container. Decocting method, with less alcohol consumption, is not heavy when taking it, and is easy to drink, especially for people who are not good at drinking. However, this method is not suitable for aromatic Chinese herbal medicines containing volatile oil.

brewing method; First, Chinese herbal medicines are decocted in water, filtered to remove residues, and then concentrated into tablets. Some medicines can also be squeezed directly to get juice, and then glutinous rice is cooked into rice. Then, the medicinal juice, glutinous rice and distiller's yeast are evenly mixed, placed in a clean container, sealed with a lid, and kept in a heat preservation place for about 1 days, so as to minimize contact with air, maintain a certain temperature, and filter residues after fermentation.

percolation method: percolation method is suitable for pharmaceutical production. Firstly, the Chinese medicinal materials are crushed into coarse powder, and then an appropriate amount of Chinese liquor is added for soaking for 2-4 hours, so that the coarse powder of the Chinese medicinal materials is fully expanded, and the coarse powder is evenly loaded into a percolator with absorbent cotton at the bottom in several times, and then pressed with a wooden stick after each loading. After loading Chinese herbal medicines, cover them with gauze and press a layer of washed pebbles; In order to avoid floating the powder after adding liquor. Then turn on the switch at the lower mouth of the percolator, then slowly add the white wine from the upper part of the percolator, and turn off the upper switch when the liquid flows out from the lower mouth, so as to pour the flowing biogas into the percolator, continue to add the white wine until it is several centimeters higher than the powder surface, then cover it, leave it for 24-48 hours, and then turn on the switch at the lower mouth to make the percolate flow out slowly. Collect percolate according to the specified amount, add correctant, stir well, seal after dissolution, stand for a few days, filter out the liquid medicine, and then add white wine to the specified amount to obtain the medicinal liquor.
