Mind-Blowing Fact
Defend the body!
The green color of mucus is caused by the enzyme that white blood cells produce to create hypochlorite, a corrosive chemical that is effective in dissolving bacteria. Hypochlorite is the same chemical that is used in household bleach. This enzyme is one of the key mechanisms that our body uses to defend itself against harmful microorganisms.
