A therapeutic composition having at least one botanical active ingredient, carvone, derived from plants such as mint Mentha sp., caraway Carum carvi or dill Anethum graveolens. Carvone is capable of anesthetizing teleost, elasmobranch, and agnathan fishes as well as amphibians by contact with skin and/or gills. Carvone has two natural enantiomers; both have anesthetic properties on these fishes and amphibians. Carvone in combinations with other sodium channel blockers such as methyl salicylate have a synergistic effect and are more efficient at anesthetizing teleosts, elasmobranchs and agnathan fishes than carvone alone. This invention has value because it offers an opportunity to forumulate fish anesthetizing drugs with a compound that is also documented to be safe for human consumption. |
