The invention discloses a parasite-expelling and fire-purging oral liquid for sheep and a preparation method thereof. The parasite-expelling and fire-purging oral liquid is prepared from non-antibiotic substances which are free of
withdrawal time and residues. The oral liquid prepared from radix euphorbiae lantum,
cyrtomium fortunei,
rheum officinale and radix stemonae is developed from effectivecomponents extracted from
plant tissue containing parasite-expelling and fire-purging substances after
processing, and the oral liquid has the advantages of being efficient, low in
toxicity, free of
pollution, high in selectivity, difficulty in
drug resistance generation and the like; the oral liquid accords with the development tendency of animal parasite-expelling
medicine from traditional organic chemical substances to environmental harmonious parasite-expelling and fire-purging
medicine. The main components of the parasite-expelling and fire-purging oral liquid come from the nature and arecompatible with the environment, the oral liquid can be degraded or metabolized into a simple
natural compound in the environment, the effective components of the oral liquid only contain the three elements including carbon,
hydrogen and
oxygen, a final product of
digestion in the environment is
carbon dioxide and water, which is extremely difficult to achieve in chemically synthesized parasite-expelling
medicine, and the oral liquid can also achieve the triple effects of purging fire, promoting growth and avoiding
drug residues.
