The Chillie plant was native to South America. It was brought to Sri Lanka by the Portuguese in the 16th century AD. Even now a pungent variety of this plant is called 'Kochchi miris' in Sinhalese and 'Kochchikkkai' in Tamil. This recalls the time when it was brought from Cochin, South India a former Portuguese enclave.
Black pepper which was exported from Sri Lanka for more than 2000 years was native to Sri Lanka and is called 'Gammiris' - Gamey miris - in Sinhalese meaning the local variety.
Chillie has 'capsicaine' and is used in ointments as a counter irritant, to relieve pain.
In Tamil there is a phrase 'ANIL ERAVITTA NAI POLA', meaning 'like a dog who has missed catching a squirrel which has scampered up a tree'. This epithet applies to a person who has just missed reaching his goal.
