If a domestic or wild animal is sick, it acts instinctively looking for some natural treatment. Plants are not only a source of food for humans and the entire animal world but also a real storehouse of medicines. Cases of self-treatment by plants of wild and domestic animals are well known. In the wild, animals are accustomed to rely only on themselves. It turned them into good “healers”. The humans adopted their experience, it helped them survive. But there are diseases that animals can’t cope with: rabies, plague, brucellosis, foot and mouth disease. Then people should help them.
