It is commonly found in forests as a gregarious undergrowth along the foot of the Himalayas, from the Ravi to Sikkim and Assam, besides Bengal, Madhya Pradesh, Maharashtra, Kerala, Karnataka, Orissa and Andhra Pradesh. The trees are also now maintained in homestead gardens, as in Kerala, or on leaf farms as in Andhra Pradesh, Tamil Nadu, Karnataka and Orissa. The western world is fast taking enthusiastically to Indian curry leaf, especially those who prefer their food to be tangy without being too hot.
