The Bhut Jolokia is cultivated in the Indian states of Nagaland and Assam. It is believed to have originated in the state of Assam.

 

Besides being used in cooking, it has also been used as a homeopathic remedy for stomach pain, a way to beat the summer heat (when the bhut jolokia is eaten, the partaker will usually start to sweat quite a bit, which will ultimately lead to a decrease in body temperature). The bhut jolokia has even been used as a weapon - locals of northeastern India smear their fences with it to keep elephants away, and the pepper has even been used in smoke bombs! 

 

Trivia – The Bhut Jolokia was rated as the hottest chilli in the guineas book of records, till the New Mexico State University's Chile Pepper Institute identified the ‘Trinidad Scorpion Moruga Blend’ as the newest hottest chili pepper as of February 2012.
