Problems solved by technology

[0004] When the usual external plasters are applied to the skin, especially to the joints, such as knees, elbows and other vigorously active parts, there will be problems such as weak application, shedding and poor air permeability, which will affect the curative effect
For example, the existing plasters have the following deficiencies: 1. Some plasters are poorly targeted and have unsatisfactory drug effects; 2. The transdermal absorption rate of the plasters is low, slow to take effect, and the drug cycle is long; 3. The active ingredients in the plasters are volatile and cause The drug effect is reduced; 4. The thickness of the plaster is not enough, and the adhesion is poor, so that the plaster is easy to be damp; 5. The ingredients are unevenly dispersed in the plaster, resulting in different quality of the plaster; 5. The air permeability of the plaster is poor, and the air permeability is not good , easy to cause skin itching and aggravate skin allergies
Equally the plaster disclosed by this invention does not relate to the transdermal problem and the viscosity problem of the plaster

Abstract

The invention provides a non-allergic rubber plaster and a preparation method thereof, and belongs to the technical field of plaster preparations. The rubber plaster comprises the following medicinalmaterials in parts by weight: 1-7 parts of herba speranskiae tuberculatae, 5-14 parts of radix aconiti lateralis preparata, 5-13 parts of rhizoma typhonii, 5-13 parts of radix aconiti agrestis praeparata, 5-13 parts of radix aconiti sinensis praeparata, 5-15 parts of rhizoma arisaematis, 5-13 parts of caulis spatholobi, 2-10 parts of mentha canadaensis l., 1-8 parts of camphora and 2-10 parts of borneolum syntheticum. The non-allergic rubber plaster uses high molecular artificial rubber instead of natural rubber, and thus the allergy problem is effectively solved; by controlling the types andcontents of main drug components in the plaster and improving auxiliary material components, the prepared rubber plaster has higher transdermal absorption rate, can rapidly absorb the effective drug components, improves the treatment effect, and meanwhile, the plaster has higher adhesive performance and higher stability.

Description

technical field [0001] The invention belongs to the technical field of plaster preparations, and in particular relates to a non-allergic rubber plaster and a preparation method thereof. Background technique [0002] Plaster therapy, which works through the skin, is one of the commonly used external treatment methods in TCM clinics. TCM external plaster uses the principle of meridian distribution of traditional Chinese medicine to fully mobilize the effectiveness of the coordination of drugs to form a compound of multi-flavored drugs. To bring into play the good effect of medicine. Because the plaster is directly applied on the body surface, it penetrates into the skin and transmits the meridians and internal organs to play the functions of regulating qi and blood, dredging the meridians, expelling cold and damp, and reducing swelling and pain. [0003] External plaster Colloidal material coated on elastic cloth or non-elastic cloth to make external plaster tape, and a finis...
