Basil is known to have powerful antioxidant properties. The natural antioxidants found in basil can protect the body against damage from free radicals, thereby combating most forms of cancer. Basil also contains flavonoids, which protect cell structures from radiation and oxygen-based damage. Basil is a rich source of beta-carotene, which helps protect cells from free radical damage.
Basil is rich in carotenoids such as beta-carotene, which can be converted into vitamin A. Beta-carotene is an even more potent antioxidant than regular vitamin A, as it not only protects cells from free radical damage, but also aids in keeping free radicals from oxidizing cholesterol in the bloodstream. By not oxidizing, cholesterol does not build up on blood vessel walls, avoiding atherosclerosis and a heart attack. Basil is also a good source of magnesium, which promotes cardiovascular health by relaxing muscles and blood vessels, improving blood flow and lowering the risk of irregular heart rhythms and cardiovascular spasms.
Evidence shows that the antioxidants and volatile oils in basil make it of great assistance to the immune system. The leaves and oil both have antibacterial properties, and can even be used to eliminate infectious diseases from surfaces. Applied topically to wounds, basil leaves may eliminate bacterial infections, while enjoying basil in food can help combat viral infections, including colds, flu, and herpes.
The essential oil of basil has been shown to provide impressive protection against unwanted bacterial growth of many types, including the ability to inhibit several species that have become resistant to commonly used antibiotic drugs. Studies have shown that washing produce in a solution containing just 1% essential oil of basil resulted in killing such bacteria, so it makes good sense to include basil in salads.
