How Do Injured Animals Care For Themselves?

When some injury or sickness threatens the health of an animal, its natural instinct diagnoses the problem and dictates what it should do. This enables it to have the right prescription and to apply the best medication to cure what may be ailing it. Animals will often act as if they knew different illnesses require different treatments.
For example, if an animal is injured, it will seek out a place of solitude where it can get complete rest. If it has a fever, it seeks an airy, shady place near water. There it remains quiet, eating very little and drinking often. If the animal is rheumatic, it exposes itself to the sunlight so as to soak up the heat to relieve its pain. Sometimes grass is eaten to induce vomiting. When an astringent is needed, certain animals will eat bark and twigs of oak trees, which contain tannic acid, an astringent medicine.
