Overview of the efficacy and functions of nitrate

Salt salt, also known as Glauber's salt or sodium sulfate, is a traditional Chinese medicinal material withPurgative, laxative, heat-clearing and swelling-reducing, softening and dispersing knotsand other main functions.Its core functions include treating stagnant heat, constipation and abdominal distension, and can be used externally to relieve swelling and pain in sores and carbuncles.The main functions include auxiliary diuresis, anti-inflammation, etc.It should be noted that it is cold in nature and should be used with caution by pregnant women and those with physical weakness.The following will focus on both internal and external use, analyzing its application scenarios and precautions.

Laxative and laxative: the core function of oral administration

However, excessive dosage may cause diarrhea and dehydration. It is recommended to follow the doctor's advice to control the dosage (3-6 grams is appropriate).Modern research has also confirmed that its sodium sulfate content can increase intestinal water content.

External heat-clearing: clinical practice for reducing swelling and relieving pain

External application of nitrate can treatSores, swelling, mastitisand other inflammation.Its cooling properties can locally cool down the body and inhibit bacterial growth. The traditional method of use is to wet apply the sodium salt solution or mix it with vinegar and apply it to the affected area.For example, "Compendium of Materia Medica" mentions that nitrate "can cure sore throat, swelling and pain, and it will be effective immediately by gargling".It should be noted that it is prohibited to use on damaged skin to avoid irritation.Modern pharmacological experiments show that its sulfate ions can reduce tissue edema, but too high a concentration may cause skin allergies.

Incompatibility and contraindications: the key to safe use
