Traditional chemical antibiotics have been used recklessly. The outcome of this is that many bacteria have developed resistance for the antibiotics. Another aspect is that frequent use of chemical antibiotics weakens person' s immune system; stimulate allergies and also cause organs damage in some cases.

Natural antibiotics are proven effective in specific cases. Garlic is considered as the one of the most beneficial natural antibiotic. Garlic stimulates the immune system and enhances the efficiency of white blood cells (responsible for fighting germs in the body). It also possesses anti-bacterial properties.

Echinacea is also a medicinal herb, which enhances the immune system and is quite effective as an anti-microbial. Colloidal silver is used in water filters because of its anti-bacterial property (disrupts the enzyme system of various type of bacteria). These are just the examples of natural antibiotics.

But, be cautious. You may get allergic reactions from natural antibiotics also. Since, chemical antibiotics prove an effective cure from bacterial infections, their use in severe health problems is essential. So, you need to be wise, while selecting the natural antibiotics for treatment.
