The majority of the illnesses that afflict man also afflict animals, but the animal does not treat them through medicines. The animal's physician in the mountains and the wilderness is its powers of taste and smell. The sick animal smells the plants that grow in the wilderness, eats those that its smell and taste find to be sweet and fragrant, and is cured. The reason is this: When, for example, the sugar component in its body becomes deficient, it craves sweet things and thus eats of sweet-tasting plants, for nature so urges and guides it. Thus, as the animal eats things that are pleasing to its smell and taste, the sugar component increases and it regains its health (73:6)
