Natural drugs refer to medications derived from natural substances such as plants, animals, and minerals, under the guidance of traditional veterinary medicine theory. These drugs can be used for animal disease prevention and treatment without undergoing chemical modification or only with simple processing. They mainly include: Animal-origin drugs: Pharmaceutical components derived from animal tissues, organs, secretions, or metabolites. Botanical-origin drugs: Drug components derived from the roots, leaves, flowers, and other parts of plants. Mineral-origin medicine: derived from natural minerals or rocks. |
