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