The Betel (Piper betle) is a spice whose leaves have medicinal properties. The plant is known by a series of different names in the regions in which it is consumed - among these are Vetrilai (Tamil), Vettila (Malayalam). The plant is evergreen and perennial, with glossy heart-shaped leaves and white catkins, and grows to a height of about 1 metre. The Betel plant originated from South and South East Asia (India, Srilanka, Vietnam, and Malaysia). The best Betel leaf is the "Magadhi" variety (literally from the Magadha region) grown near Patna in Bihar, India. In Kerala, the famous variety of betel leaf is from Venmony near Chengannur and it is called "Venmony Vettila". Betel leaf cultivated in Tirur, Kerala is also of fine quality. Betel leaves exported from Tirur are famous in Pakistan as "Tirur Pan".
