Abstract

The invention belongs to the field of traditional Chinese medicine preparation, and particularly relates to a black plaster and a preparation method thereof. The black plaster is prepared by refining medicinal materials, emu oil and yellow lead into paste, and spreading on a backing material. Because emu oil does not contain phosphorus, the emu oil can smoothly pass through skin barriers to reach the discomfort of human bodies, and has super-strong skin permeability, which is a characteristic that other oil does not have. And has the property of healing wounds due to the fatty acid composition, particularly high levels of gamma-linolenic acid and oleic acid. Linolenic acid is an unsaturated fatty acid, and can relieve joint pain; oleic acid is a monounsaturated fatty acid, and can be used for reducing inflammation of skin tissue and for adjuvant treatment. For the preparation of the black plaster, because the boiling point of the black plaster is lower than that of common sesame oil, tung oil or sesame oil and the like in the existing preparation, the medicine can be boiled at a relatively low temperature, the obtained medicine has more effective components, and the black plaster is not easy to lose efficacy due to high-temperature oxidation or other chemical actions.

Description

Black plaster and preparation method thereof
Technical Field
The invention belongs to the field of traditional Chinese medicine preparation, and particularly relates to a black plaster and a preparation method thereof.
Background
The plaster is one of the main methods for external treatment in traditional Chinese medicine, and has a long history in China. The plaster has the advantages of convenient use, low price, rapid action, obvious curative effect and the like, and is most suitable for people who are not allowed to take the medicine and can not take the medicine. Especially for difficult and complicated diseases which can not be cured for a long time, the traditional Chinese medicine composition can show unique work and force, and is a traditional Chinese medicine external treatment wonderful prescription which is deeply favored by the broad masses of common people.
Currently, the black paste medicament sold in domestic markets and used clinically is prepared by processing the medicaments by using vegetable oil (such as sesame oil, tung oil and the like) and yellow lead as substrates and refining the medicaments at high temperature (above 270 ℃). The specific method comprises frying the Chinese medicinal materials and vegetable oil in a frying pot at 200-220 deg.C until they are yellow, filtering to remove residues, refining at 270-350 deg.C, adding Plumbum Preparatium, removing toxic materials, and spreading on a backing material. The method has the following disadvantages in production and use: 1. after the medicine is refined at a high temperature of more than 270 ℃, the loss of active ingredients is more, and the curative effect of the medicine is influenced. 2. The vegetable oil used as the base material has poor permeability, and influences the deep absorption of the effective components of the medicine into the skin.
Disclosure of Invention
The invention aims to overcome the defects in the prior art and provides a black plaster and a preparation method thereof.
In order to achieve the purpose, the invention adopts the technical scheme that:
a black plaster is prepared by mixing medicinal materials, emu oil and Plumbum Preparatium, making into paste, and spreading on backing material.
Preferably, the mass ratio of the medicinal materials, the emu oil and the yellow lead is 0.5-1: 3-1: 1.
the invention also comprises a method for preparing the black plaster, which comprises the following steps: 1) frying materials: heating emu oil to 80-125 deg.C, adding the rest materials except the valuable materials, stirring to make the materials heated uniformly, frying until the ointment turns yellow, removing residues, filtering, and cooling to obtain base ointment oil; 2) parching pill: placing Plumbum Preparatium in a clean pan, parching with slow fire until water vapor disappears, and loosening; continuously stir-frying with a shovel after the fire is turned off; 3) oil refining: putting the base cream oil obtained in the step 1) into a clean pot, decocting with strong fire until boiling, namely changing to small fire, maintaining the oil temperature at 120-195 ℃, dripping oil on cold water by using a stick, and obtaining the required oil material after the oil drops bead and the cold water are not scattered; 4) the following components: slowly adding the yellow lead obtained in the step 2) into the oil material refined in the step 3), and continuously stirring until the oil material is boiled, wherein the oil material overflows bubbles and smokes, and obtaining the oil lead when the smoke is slightly exhausted; dipping the red lead into a stainless steel plate by a wooden stick, and cooling, then, trying to pinch the red lead by a dry hand until the red lead is stuck and no red lead is left on the hand when the hand is loosened, turning off the fire at the moment, and continuing to stir until the red lead is cooled; 5) fire toxin removal: after the oil pills obtained in the step 4) are made into paste, the paste is placed into a cold water basin to be soaked for 3-5 days, and water is changed for 2-3 times every day to remove fire toxin; 6) adding fine powder; grinding the valuable medicinal materials in the medicinal materials into fine powder by using a superfine grinder, slowly adding the fine powder into the re-melted plaster obtained in the step 5), and stirring; 7) spreading plaster: spreading the fine plaster obtained in step 6) on sterilized paper or cloth, and cooling.
Preferably, the fried explosive materials in the step 1) are added and cooked firstly and secondly according to different properties of the explosive materials; firstly, putting hard plant root and stem medicinal materials into a container, soaking the medicinal materials in emu oil, boiling the medicinal materials with slow fire, and boiling the medicinal materials for 1 to 1.5 hours; simultaneously adding herbal materials such as flowers, grasses, leaves and skins which are not resistant to boiling, and boiling for 1.5-2.5 hours with medium fire to change the external color of the herbal materials in the container into dark brown and the internal color of the herbal materials into brown, stopping heating, and heating at the rest temperature until the herbal materials are boiled to dry.
Wherein, the emu oil comprises the following components in parts by weight: 0.4 part of myristic acid; 22 parts of palmitic acid; 9.6 parts of stearic acid; 3.5 parts of palmitoleic acid; 47.4 parts of oleic acid and 15.2 parts of linoleic acid; linolenic acid 0.9 part.
Compared with the prior art, the invention has the beneficial effects that:
because emu oil does not contain phosphorus, the emu oil can smoothly pass through skin barriers to reach the discomfort of human bodies, and has super-strong skin permeability, which is a characteristic that other oil does not have. And has the property of healing wounds due to the fatty acid composition, particularly high levels of gamma-linolenic acid and oleic acid. Linolenic acid is an unsaturated fatty acid, and can relieve joint pain; oleic acid is a monounsaturated fatty acid, and can be used for reducing inflammation of skin tissue and for adjuvant treatment. For the preparation of the black plaster, because the boiling point of the black plaster is lower than that of common sesame oil, tung oil or sesame oil and the like in the existing preparation, the medicine can be boiled at a relatively low temperature, the obtained medicine has more effective components, and the black plaster is not easy to lose efficacy due to high-temperature oxidation or other chemical actions.
