Embodiment 1

[0033] Licorice 600g Angelica dahurica 400g Scutellaria baicalensis 300g Honeysuckle 500g Rhubarb 400g Aloe vera 300g

[0034] Crush the above drugs into coarse particles (3-5 meshes), add 5 times the amount of cold water to soak for 48 hours, filter the extract to get the filtrate. Add 3 times the amount of cold water to the filter residue and soak for 24 hours, and filter again to obtain the filtrate. The two filtrates were combined and concentrated by evaporation. After cooling, ethanol was added and placed at low temperature for 48 hours. The mixture was filtered and the filtrate was evaporated and concentrated again to obtain a brown viscous extract. At this time, the weight loss on drying of the extract was below 35%. The extract was concentrated and dried again to generate crude crystals for future use.

Embodiment 2

[0036] 840 grams of licorice, 450 grams of Angelica dahurica, 360 grams of skullcap, 480 grams of honeysuckle, 450 grams of rhubarb, 420 grams of aloe vera

[0037] Crush the above medicines into coarse grains (3-5 meshes), add 5 times the amount of clear water to soak for 4 hours, then heat with steam at 80-90°C for 4 hours, and filter to get the filtrate. Add 3 times the amount of clear water to the filter residue, heat it with steam at 80-90°C for 2 hours, and filter again to obtain the filtrate. The two filtrates were combined and concentrated by evaporation. After cooling, ethanol was added and placed at low temperature for 48 hours. The mixture was filtered and the filtrate was evaporated and concentrated again to obtain a brown viscous extract. At this time, the weight loss on drying of the extract was below 35%. The extract was concentrated and dried again to form crude crystals, which were then recrystallized in dilute ethanol solution to obtain refined products for f...

Embodiment 3

[0038] Embodiment 3 preparation ointment

[0039] Prescription: 10 grams of crystallization of medicine prepared by embodiment 1 20 grams of triethanolamine

[0040] 50 grams of glycerin, 150 grams of stearic acid, 20 grams of lanolin

[0041] 250 grams of white petrolatum, 1 gram of ethyl hydroxybenzoate, distilled water to 1000 grams

[0042] Preparation method: Melt stearic acid on a water bath, add lanolin and white petrolatum, and heat to 80°C in a water bath; dissolve triethanolamine, glycerin, and ethylparaben in water, heat to 80°C on a water bath, and continue Gradually add the oil phase to the water phase under stirring, stir and condense to obtain an ointment, and finally add the finely ground drug crystals and stir evenly to obtain.
