Indications
Tulsi (holy basil, Ocimum tenuiflorum, also called Ocimum sanctum) is a sacred and medicinal plant widely used in Ayurvedic and Unani medicine. Its leaves are traditionally used for cough, colds, sore throat and fever, to help the body cope with stress, and as a general tonic. It is a common ingredient in herbal cough syrups and teas. Some small studies support mild benefits, but scientific evidence is limited and it does not cure infections.
How It Works
Tulsi leaves contain eugenol, ursolic acid, rosmarinic acid and other plant compounds. These are thought to have mild anti-inflammatory, antioxidant and antimicrobial effects, to soothe the throat and to help loosen mucus. In Ayurveda it is described as an adaptogen, a herb that helps the body adapt to stress.
