On the Preparation and Efficacy of Alum and Vinegar Topical Powder
1. Compatibility of Raw Materials
To make Aluminum Sulfate - Calcium Acetate Topical Powder, it is necessary to select raw materials. For alum, pure aluminum sulfate (Aluminum Sulfate) is preferred, its texture is pure, and there is no impurity doping to ensure the purity of the efficacy. Calcium acetate should also be of high quality, and the two should be compatible in an appropriate proportion. Aluminum sulfate takes its dryness and wetness to converge, while calcium acetate assists in synergy. The two complement each other and co-construct the basis of this drug.

Second, the method of preparation
When preparing, first grind the aluminum sulfate carefully to make the powder uniform and delicate, and the mesh number reaches the appropriate standard, so that the drug effect can be fully exerted. Calcium acetate is also ground according to this, and then the two are placed in a clean container, and the mixing is fully stirred and mixed with exquisite techniques. The stirring process must be uniform and long-lasting, so that the two are uniformly integrated without local segregation. After mixing, it is carefully sieved to remove the particles that have not been fully ground, so that the texture of the powder is more uniform, which is conducive to the absorption of external use.

Third, the effect of the main treatment
The external application of alum vinegar powder is significant. In the case of skin wet sores, it can dry and relieve itching. If the skin is impregnated with evil moisture, itching is intolerable, and running water exudes, apply this medicine externally. The dryness and dampness astringent effect of aluminum sulfate can quickly stop exudation, and calcium acetate can also help relieve itching and make the skin gradually dry. For mild burns, this medicine can clear heat and cool blood, relieve redness, swelling, heat and pain in the scalded area. Its pharmacology is that aluminum sulfate and calcium acetate work together to reduce local inflammation and promote skin repair. It can also be used for hyperhidrosis of the feet, restrain and stop sweating, improve the damp state of the feet, and prevent diseases such as athlete's foot caused by moisture.

4. Usage and Dosage
