Problems solved by technology

Western medicine often uses nifedipine, pyridine, etc., which have relatively large toxic and side effects, ineffective therapeutic effect, and great dependence.
Most traditional Chinese medicines for frostbite exist in the form of traditional Chinese medicine compound, without index components, with inaccurate pharmacological effects and difficult quality control, which limits their development and application as medicines

Abstract

The invention discloses a total gingerol ointment for treating frostbite, which is prepared from total gingerol and auxiliary materials in the following weight proportions: 2-30 parts of total gingerol, 15-70 parts of oily raw materials, and 0-60 parts of wax , 1-15 parts of emulsifier, 4-15 parts of humectant, 0.1-0.2 part of preservative, 0.005-0.2 part of antioxidant, 20-80 part of water; the oily raw material is one of grease and wax or a mixture of both. The preparation steps are: heating the oily raw material and emulsifier to 70-90°C and stirring to obtain an emulsion; then adding the moisturizing agent and preservative into water, stirring continuously, and heating to 70-90°C to form a solution; mixing the solution with The emulsion is mixed slowly, stirred and emulsified, and when the temperature is lowered to 40-50°C, antioxidants and total gingerols are added, stirred evenly, and an ointment can be made. The ointment has clear active ingredients, definite pharmacological and drug effects, easy quality control, good curative effect for treating chilblains, and less toxic and side effects.

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. Histologically confirmed chilblain is a lymphocytic vasculitis. Chilblains usually manifest as single or multiple swollen bright red or dark red macules, papules or nodules, and blisters and ulcers can be seen in severe cases. Usually accompanied by itching or burning sensation, frostbite is prone to relapse, which is related to chronic vasculitis of local skin and decreased skin resistance after the disease. [0003] The medicine for the treatment of chilblain at present has western medicine, traditional Chinese medicine, is in the majorit...
