Overview of the functions and functions of gypsum

Gypsum is a commonly used mineral medicine in clinical Chinese medicine. Its main component is hydrated calcium sulfate (CaSO₄·2H₂O). It has a pungent, sweet and cold nature and taste. It returns to the lung and stomach meridians and has many functions.Clear away heat and purge fire, relieve restlessness and quench thirst, astringe and promote muscle growthThree core functions.Its application is divided into oral and external use: oral use is mainly used to treat excess heat syndrome such as high fever, polydipsia, lung heat, cough and asthma; external use is used for skin problems such as eczema, ulcers, burns and scalds.Modern research has confirmed its anti-inflammatory and cooling effects, but people with spleen and stomach deficiency should use it with caution.The pharmacological mechanism, classic compatibility and contraindications for use will be described in detail below.

Gypsum's heat-clearing and fire-reducing effects and its clinical application

GypsumClear away heat and purge fireThe effect is particularly outstanding, and it is especially good at clearing away excessive heat in the lungs and stomach.The "Baihu Decoction" in the traditional Chinese medicine classic "Treatise on Febrile Diseases" uses gypsum as the king medicine, combined with anemarrhena, japonica rice, etc., and is used to treat Yangming Meridian syndrome of high fever, profuse sweating, polydipsia and large pulse.Modern research has found that calcium ions in gypsum can inhibit the body temperature regulation center and play a physical cooling role.For fever caused by pneumonia, influenza, etc., gypsum can quickly relieve symptoms, but its nature is severe cold, so it needs to be used strictly based on syndrome differentiation to avoid damaging Yang Qi.

The external efficacy and scientific verification of gypsum

Calcined gypsum (processed products for external use) hasConvergence and muscle growthEffective, often used for skin ulcers or wounds.The principle is to promote capillary contraction through calcium ions, reduce exudate, and accelerate wound healing.For example, "Compendium of Materia Medica" records that gypsum "can be used as a powder to apply on sores", and it is also used in modern clinical practice for minor burns or eczema.It should be noted that calcined gypsum needs to be ground into very fine powder before use to avoid impurities irritating the wound surface.In addition, plaster external application only has an auxiliary effect on bacterial infections, and severe infections still need to be treated with antibiotics.

Contraindications and incompatibility of use

Although plaster is effective, it is not a panacea. There are three taboos to be aware of:Those with spleen and stomach deficiency should not take it., may aggravate diarrhea;Use with caution in those with yin deficiency and internal heat., which may consume Yin fluid;Taking large amounts for a long timeMay interfere with mineral metabolism.In terms of compatibility, gypsum often synergizes with anemarrhena and licorice, but caution should be used when using it with warm medicines such as aconite and dried ginger to avoid conflicting properties.Special groups such as children and pregnant women should use it under the guidance of a physician and are not allowed to increase or decrease the dosage on their own.

Summary and scientific understanding

Gypsum is the "first product to clear away heat" and its efficacy has been proven for thousands of years, but it needs to be viewed rationally: on the one hand, it has a definite effect on excess heat syndrome, and if combined with modern medicine, it can improve the treatment efficiency of respiratory infections; on the other hand, its cold and cooling properties determine the limitations of the applicable population.Be sure to follow when using"The disease will stop immediately"In principle, avoid overcorrecting.Future research may further explore the molecular targets of its anti-inflammatory mechanism and give modern value to traditional medicinal materials.

Quoting the views of famous people: Zhang Jingyue, a doctor of the Ming Dynasty, emphasized in "Jingyue Complete Book": "Gypsum should not be used unless it is extremely hot. It must be used properly, like a drum to a drum."
