For thousands of years, people have been using plants to treat various ailments. However, few of the plants still used in the traditional way have been subjected to the rigorous medical testing of modern medications. This study examined inhibitory activity of selected traditional herbs against Staphlococcus aureus, Enterococcus faecalis, Pseudomonas aeruginosa, Klebsiella pneumoniae, Candida albicans, and Saccharomyces cerevisiae by measuring the inhibition rings formed by the herbal preparations on nutrient agar plates. Garlic showed the strongest inhibition against the microbes tested, but bay, oregano, and alum root showed considerable inhibition as well. Jimsonweed showed slight inhibition against certain microbes, while brown mustard only inhibited the yeasts. Organic extracts from jimsonweed were fractionated in an attempt to find and concentrate the active compound.
