I’m using these spray bottles for my bamboo charcoal vinegar. One is the original liquid (distilled). The 2nd is diluted 5 times with water. The 3rd one is diluted 10 times. The 1st one is used for insect bite, cut (wound), skin problem, etc. Spray directly onto the skin. If you spray into your mouth, it will be easier way to take (drink). Also it deodorise your breath. If I’d like to spray into my nose, The 1st one may be a bit strong. Use the 2nd one. When I had itchy eyes with hay fever, I spray directly into my eyes the 3rd one. Please try in any way.
