Synthetic vinegar, commonly known as vinegar essence, is mainly composed of acetic acid and diluted with edible glacial acetic acid. Vinegar has a high concentration of acetic acid and a strong sour taste, so it should be diluted when used. Generally speaking, the content of acetic acid should not exceed 3 -4%. Vinegar does not contain nutrients in vinegar, so it is not easy to go moldy and deteriorate, but it also lacks the fragrance and nutritional function of vinegar. Therefore, it is better to be jealous unless necessary. It should be reminded that glacial acetic acid is corrosive to some extent. If you accidentally come into contact with skin or clothes, please clean them in time.

Buy a bottle of vinegar and get some white flour (ground from wheat, used to make steamed bread at home. Not another name for a drug), and then add the two together to make a thick paste. Finally, apply it to the affected area. What needs to be remembered is not to draw too big, just a circle smaller than the mole. This thing is harmful to the skin (but compared with the medicine for removing boils, the damage is almost negligible). After all, it is something that can be eaten directly.

This method can only be used for boils, that is, spots and boils with melanin deposition.
