Abstract

The invention discloses a total gingerol ointment for treating chilblain. The total gingerol ointment is prepared from total gingerol and the following auxiliary materials in parts by weight: 2-30 parts of total gingerol, 15-70 parts of oil materials, 0-60 parts of waxes, 1-15 parts of emulsifier, 4-15 parts of humectant, 0.1-0.2 part of preservative, 0.005-0.2 part of antioxidant and 20-80 parts of water, wherein the oil materials are one or a mixture of two of grease and wax. Preparation steps for the total gingerol ointment are as follows: heating the oil materials and the emulsifier to 70-90 DEG C, and stirring to obtain an emulsified liquid; then, adding the humectant and the preservative into water, stirring continuously, and heating to 70-90 DEG C to form liquor; slowly mixing the liquor with the emulsified liquid, stirring and emulsifying, adding the antioxidant and the total gingerol while cooling to 40-50 DEG C, and uniformly stirring to prepare the ointment. The ointment disclosed by the invention is specific in active ingredient, exact in pharmacology and drug efficacy, easy to control, good in treatment effect for treating chilblain, and small in toxic and side effect.

Description

technical field [0001] The invention relates to an ointment for treating frostbite and a preparation method thereof. Background technique [0002] In winter, due to the cold weather, many people are habitually troubled by frostbite in winter. Chilblain is a localized, erythematous inflammatory lesion caused by exposure to a sub-zero cold environment. It is an abnormal inflammatory response to a cold, humid, and non-freezing environment.
