Purple basil can be used in any recipe that calls for sweet basil, although the flavor is more intense than traditional sweet basil. Purple basil is also a nutritional powerhouse with vitamins A, C, K, B6, iron, calcium, potassium, and tryptophan. It is anti-inflammatory and nutrient-dense, which means it can contribute to a diet that can help you to reduce chronic inflammation. It is a useful seasoning in Italian, Greek, Mexican, and tomato dishes.
