Tulsi (also known as Ocimum sanctum or holy basil) is an aromatic plant in the mint family (Lamiaceae) native to India and Southeast Asia.[1] It is rich in various bioactive phytochemicals, including rosmarinic acid, apigenin, ursolic acid, caffeic acid, ferulic acid, and eugenol.[2][1] Tulsi is used primarily as a medicinal herb, and it is distinct from sweet basil (Ocimum basilicum), which is more often used as a culinary herb.[1] Despite a long history of use as a traditional medicine, very little clinical research exists.
