Ocimum basilicum
Basil
From its native India, sweet basil (O. basilicum) was introduced into Europe in ancient times. Views and traditions associated with the herb have been mixed. Some cultures associate it with hatred and misfortunes, while others regarded it as a love token. Dioscorides said that it should never be taken internally, while Pliny advised smelling it in vinegar for fainting fits. In Ayurvedic medicine, holy basil (O. sanctum) is known as tulsi and the juice is an important tonic.
