That’s a really great question. What is douching? The word “douche” means to soak or wash in French. Douching is washing or cleaning out the vagina with water or other mixtures of fluids. Usually douches are prepackaged, mixed with water and vinegar, baking soda, or iodine. The mixtures usually come in a bottle and can be squirted into the vagina through a tube or nozzle. Women can buy these products at the drug and grocery stores.
