What is crucial is what you are going to do.

Take a common 30-degree white glass bottle as an example.Use vinegar.And distilled spirits.For example.

To prevent motion sickness, take one spoonful in half a cup of warm water.

For skin mites, use a 1:10 ratio mixed with warm water. Apply to the affected area with a ball of gauze for ten minutes each time, wash with clean water, and persist for about three weeks. After peeling off and forming scabs, continue using a 1:15 ratio for a period of time to prevent recurrence.

For flat warts, use a 1:2 ratio mixed with warm water externally on the affected area for one month, applying it for twenty days. The skin will become damaged and painful, causing the wart to fall off; persistence is necessary as scars generally do not form.

For black skin on elbows and knees, soak medical gauze in vinegar and spirits at a 1:1 ratio mixed with water, then fold into squares and stick onto the affected area with adhesive bandages. Change the gauze daily for one to two weeks until it becomes very painful, after which new skin will grow. Some people with scar-prone skin may have red skin, but it will fade over half a year.

When stir-frying, use vinegar and spirits at a 1:5 ratio mixed with water.
