The amount of food of salt is 10 g per 1 l of water. Action solutions – preventing the penetration of toxic substances in the lower digestive tract (bowel).
Salt solutions after food poisoning shows a few hours later when part of the toxic substances has already passed into the intestine. After washing, make irrigation of the stomach, salt laxative.
