Rosemary, an herb used in many dishes, is a great pathogen-fighter, which means it can help fight various fungi and bacteria, as well as relieve minor cuts and burns. The herb is also a natural solution for mild flea problems, repelling ticks and various critters from adventurous or outdoorsy pets. Rosemary is also a natural anti-inflammatory, fighting redness and swelling. And, of course, the herb leaves dogs with an exceptionally glossy coat.
