Mouth and eyes

Teeth, gums, dry eye and eye infections. Sugar-free gum and fluoride do measurable things; most herbal mouthwashes do little more than the mechanical act of rinsing. Eye problems are the part of this handbook where self-treatment is most dangerous — a chemical splash, a sudden loss of vision, a painful red eye with a cloudy cornea or a penetrating injury are all the same instruction, which is to get care now.
