While most basil varieties are treated to be annuals, others are perennial that tend to grow in tropical, warm climates.

The plant of basil blooms tiny white flowers and comes with a thick foliage. The fresh leaves of basil emit a fresh, minty smell and taste sweet. On the other hand, its leaves, when used in dry form, emits earthy and spicy scents.

Now, these chains of free radicals are the chief cause for oxidative stress, causing further damage to the body cells.

The oxidative stress can be reduced if an individual consumes adequate antioxidants. Basil’s two significant water-soluble antioxidants — viceninare and orientin strengthen the immune system, protects the DNA, cellular structure, and delays the aging process. (10)
