Due to the frequent use of antibiotics, many germs have developed resistances, which can be dangerous in the case of infections, as the antibiotics then no longer work. However, nature has its own side-effect-free antibiotics. Many plants, essential oils, and foods have antibiotic properties when used correctly and are therefore referred to as natural antibiotics. These include garlic, honey, and lemon, as well as calendula, tea tree oil, and propolis. This guide shows what natural antibiotics are available, what common ailments they can help with, how to use them in case of illness, how to easily prepare them at home, and what products are available.
