Basil is an excellent source of vitamin K, a nutrient that assists in faster wound healing, and is a good source of iron to build the protein hemoglobin to transport oxygen through the blood. The aromatic leaves also contain vitamin A to maintain healthy organ functioning, calcium to strengthen bones, manganese to stimulate protein digestion, and antioxidants to provide anti-inflammatory properties to protect against free radical damage. Basil contains an aromatic fragrance and flavor due to essential oils such as linalool, methyl chavicol, and eugenol.
