SO WHAT MAKES A CHILLI HOT
Capsaicin is the chemical compound found in chillies, which makes them hot.Pure capsaicin measures 16,000,000 scoville units.
This is the Everest of the heat scale – nothing is hotter. It is an irritant to mammals, but not effective against birds, snails or slugs, which may explain why they enjoy munching your chillies. Capsaicin will take effect upon sensitive skin, eye contact, and inhalation, and cause burning/stinging pain, and can also produce nausea, vomiting, abdominal pain… and burning diarrhoea. Nice! It does not actually cause a chemical burn, but reacts with sensory neurons which stimulate the brain into believing the exposed area is experiencing excessive heat or abrasive damage.
