Just like man-made antibiotics, onions and garlic have antimicrobial, anti-inflammatory and bactericidal properties. Most importantly, the latter property is effective against all types of pathogens.

These properties are inherent in their high content of substances such as phytoncides (volatile essential compounds), flavonoids and allicin. Also their bulbs contain a wide range of vitamins and trace elements.
