Thai basil, or horapha (Thai: โหระพา), is widely used throughout Southeast Asia and plays a prominent role in Vietnamese cuisine. It is the cultivar most often used for Asian cooking in Western kitchens. Holy basil (O. tenuiflorum), or kaphrao (Thai: กะเพรา), which has a spicy, peppery, clove-like taste, may be the basil Thai people love most.[1]:93[5].
