What are the uses and usage of potassium permanganate?

Potassium permanganate looks black and purple in appearance. It is a substance with extremely high oxidizing properties, so it is often used for disinfection in medicine, especially in gynecology, where it has a very high application rate. Of course, potassium permanganate is not enough to have just this little effect. It is also very effective in treating axillary odor and athlete's foot and purifying water. Next, I will introduce to you in detail the purpose and usage of potassium permanganate.

There are four main effects of potassium permanganate powder:

First, treat the infected wound. If the wound becomes purulent, or if boils, bedsores, etc. develop, it can be cleaned with 1:1000 potassium permanganate powder. People with anal diseases such as anal fistula, anal fissure, and hemorrhoids can take a sitz bath or apply it externally to the affected area. It has the effects of preventing infection, astringing, relieving pain, relieving itching, and reducing inflammation.

Second, potassium permanganate powder can be used for gynecological inflammation. After suffering from bacterial vaginitis, cervical erosion or induced abortion, laser surgery for genital warts and other vulvar surgeries, using 1:5000-1:10000 potassium permanganate powder for external washing or sitz bath can help control infection and promote healing. This method is also applicable to infections in the external genital area of ​​male patients. In addition, newly married women can prevent honeymoon cystitis by cleaning the vulva with a 1:2000 aqueous solution.

Third, eliminate armpit odor and foot odor. External washing with potassium permanganate powder at a concentration of 1:5000 can help reduce the unpleasant odor of underarm odor; patients with athlete's foot can also soak their feet in a solution of this concentration to relieve itching and reduce foot odor.

Fourth, disinfect fruits, vegetables and tableware. To disinfect instruments, soak them in 1:1000 potassium permanganate powder for 15 minutes and then rinse them with running water. When fruits and vegetables are contaminated by bacteria, they can be sterilized by soaking them in a solution of this concentration for 5 minutes without changing their color and taste.

Function of potassium permanganate:

1. Start a fire:

According to the principle that potassium permanganate will generate heat and release oxygen when it contacts, rubs and collides with organic matter, which will cause combustion, we can mix one part of sugar with two parts of potassium permanganate and grind it in the middle of dry wood chips. If the weather is dry, the wood chips will burn quickly, in a short time and with good effect. It is reported that if you pour a small spoonful of potassium permanganate on a newspaper, add a few drops of automotive antifreeze, and crumple the newspaper into a ball, it will catch fire within 30 seconds.

2. Purify water:

Potassium permanganate is a common additive used by water plants to purify water. When collecting water in the wild, add three or four potassium permanganate grains to one liter of water and it can be drunk after 30 minutes.

3. Anti-inflammatory:

Potassium permanganate is a strong oxidant. When it comes into contact with organic matter, it releases new ecological oxygen and has the effect of killing bacteria. It has a very strong bactericidal effect. In clinical practice, a solution with a concentration of 1:2000-1:5000 is often used to rinse skin wounds, ulcers, thrush, abscesses, etc. The solution is used for gargling to remove bad breath and disinfect the oral cavity. It should be noted that the concentration of the solution must be accurately controlled, as too high a concentration will cause local corrosion and ulceration. Time must be considered when preparing the solution. Potassium permanganate releases oxygen slowly, and the soaking time must reach 5 minutes to kill the bacteria. Use cold boiled water to prepare the solution, as hot water will make it ineffective.

4. Gastric lavage:

When poisoning occurs by mistake ingestion of plants in the wild, gastric lavage should be performed as soon as possible to reduce the absorption of toxic substances. A simple method is to wash the stomach with a 1:1000-1:4000 concentration of potassium permanganate solution. A simple way to test this concentration is to look directly at the solution and see that it appears light purple or light red. If the solution appears purple or dark purple, its concentration has reached 1:100-1:200. This extremely high concentration of potassium permanganate solution can cause ulceration of the gastric mucosa and should never be used for gastric lavage. Accidental ingestion of extremely high concentrations of potassium permanganate solution can cause poisoning, so please be careful when using it safely.

5. Marking for outdoor survival:

If you get lost in the snow, you can sprinkle potassium permanganate particles on the snow. The purple color produced can guide rescuers. However, the color usually only lasts about two hours.

6. Prevent and control vegetable diseases:

Manganese is one of the trace elements needed by crops. When crops are deficient in manganese, applying a small amount of potassium permanganate can prevent manganese deficiency, but the dosage should not be too large. Too much manganese will poison the crops. Potassium is one of the three major nutrients needed by crops. Applying a small amount of potassium permanganate is of little significance in supplementing potassium.
