2. Oil of Oregano
Oregano is another tasty natural antibiotic, a benefit linked to its carvacrol content. This natural antibiotic is good for all sorts of bacterial infections, but is especially lauded for its use in GI tract infections.
For best results, look for oregano oil that contains at least 70% carvacrol. This product is also anti-fungal, so you can use it topically for skin issues as well.
