A natural and inexpensive antibiotic is garlic, which has been used by many civilizations for taking care of intestinal worms. In ancient times, people used to place fresh cloves of this medicinal spice in their shoes. As they walked, the cloves got crushed and the extracted oil was absorbed by the skin. So, if you do not prefer the taste of raw garlic, you can use this method, because either way, it solves the problem.
