The G4 green chilli is the fruit of plants from the genus Capsicum, members of the nightshade family, Solanaceae. The substances that give chilli peppers their intensity when ingested or applied topically are capsaicin and several related chemicals, collectively called capsaicinoids.

The chilli fruit is hollow with many seeds. They are found in different colours like green, orange, white, yellow and red. Pungency varies in different varieties. Red chillies get their colour from a colouring compound called capsanthin and have a hot, pungent taste due to a chemical called capsaicin.

The fact that there is a lot of vitamin C in chilli or that it is a great pain reliever is nothing new. But did you know that it works as an effective elephant repellent or that it can be as expensive as a new car? Chilli has been surprising the world for thousands of years.
