How to use magnesium sulfate powder for external application

External application of magnesium sulfate powder has the effect of reducing inflammation and swelling. Its usage is relatively simple and can be used for about 15 minutes each time. It has high penetration ability and can achieve the effect of reducing swelling and relieving pain. It can achieve a relatively satisfactory therapeutic effect clinically. In addition, it can also be taken orally on an empty stomach in the early morning. It has a choleretic effect and anticonvulsant effect. It is also quite good in lowering blood pressure.

How to use magnesium sulfate powder for external application

Method of external application of magnesium sulfate solution: Patients should apply hot compress with magnesium sulfate solution and warm water bag within 48 hours and cold compress for 48 hours. The method is to soak gauze or cotton wool in 50% magnesium sulfate solution, then take it out and apply it to the affected area, and place a warm water bag on the gauze or cotton wool.

When applying a cold compress, apply magnesium sulfate solution directly to the affected area. The duration of external application is about 15 minutes each time. The number of applications per day can be flexibly controlled according to the size of the nodule and the severity of the inflammatory reaction. The smaller the nodule, the better the treatment effect. Because magnesium sulfate has the pharmacological effects of hypertonicity, detumescence and analgesia, it is used in clinical practice and has achieved relatively satisfactory results.

1. The role of magnesium sulfate powder

Magnesium sulfate can produce completely different pharmacological effects due to different administration routes. For example, oral magnesium sulfate is rarely absorbed and has laxative and choleretic effects; external hot compresses of magnesium sulfate have anti-inflammatory and detumescent effects; and injections can also cause central nervous system inhibition and skeletal muscle relaxation.

Oral magnesium sulfate is rarely absorbed in the intestines and therefore has a good laxative function, so magnesium sulfate is also called "Epsom salt". After oral magnesium sulfate solution reaches the intestinal cavity, it prevents the water in the intestine from being absorbed by the intestinal wall. Therefore, magnesium sulfate can be used to treat constipation, abnormal intestinal fermentation, and intestinal examination or preoperative preparation; combined with anthelmintics, it can also make intestinal parasites easier to expel. Each time, 5 to 20 grams of magnesium sulfate can be dissolved in 100 to 400 ml of warm water and taken orally once in the morning.

Oral magnesium sulfate can also stimulate the duodenal mucosa, reflexively causing relaxation of the common bile duct sphincter and contraction of the gallbladder, thereby promoting gallbladder emptying. It has a "choleretic" effect and can be used to treat cholecystitis and cholelithiasis. Take 2-5 grams each time, 3 times a day, orally before or during meals.

2. Usage and dosage of magnesium sulfate powder

Catharsis: Take 5-20g orally each time, usually in the morning on an empty stomach, and drink 100-400ml of water at the same time. It can also be dissolved in water before taking.

Choleretic: 2-5g each time, 3 times a day, before meals or between meals. You can also take 33% solution, 100ml each time;

Anticonvulsant, hypotensive, etc.: intramuscular injection of 25% solution, 4-10 ml each time; or dilute 10 ml of 25% solution with 5%-10% glucose injection to 1% or 5% concentration and then drip intravenously; for the treatment of angina pectoris, dilute 10 ml of 10% solution with 10 ml of 5%-10% glucose injection and then slowly inject intravenously, once a day for 10 consecutive days.
