antibiotic foodsWhat is a natural antibiotic?

Antibiotics refer to a group of powerful medicines to cure bacterial and microbial infections. These medicines fight bacteria by hindering their reproductive system or completely destroying them.

When a bacterium enters your body, the immune system usually is activated and kills it. Even if the bacterium is able to induce symptoms, the immune system can usually cope by producing antibodies to combat the disease. The immune system learns how to fight.

Antibiotics are being used around the world in excess. This potential overuse is leading to an increased number of bacterial infections. Moreover, this misuse is also contributing to antibiotic resistance. The bacteria are learning to fight back.

Antibiotic resistance is particularly common in the United States. It is also a threat to all the countries in the world. [1] According to an estimate, 25000 people die every year due to antibiotic-resistant bacteria. [2]

This where natural antibiotics come in. Plants have been fighting pathogens for millions of years. They have developed a wide variety of compounds that have antimicrobial and antibiotic properties.

There is a natural antibiotic for almost any infection and these superfoods represent a whole new line of defense against infection.

Natural antibiotic foods give humanity an alternative when traditional medicine fails.
