14 Natural Antibiotics To fight Infection (Without Harmful Side Effects)

When people get sick with an illness or infection, they usually head to the doctor’s office for medicines that ultimately do more harm than good.

Antibiotics, also known as antibacterials, are types of medications that destroy or slow down the growth of bacteria. However, overuse of these drugs can be very harmful to the body especially for the gut health, which in turn can make the body more suspectable to infections.

Antibiotics are poisons that should destroy bacteria and we use them to treat infections which are a result of bacteria. Moreover, antibiotics may lead to food allergies and various intestinal disorders.
