What are chilli peppers (Capsicum annuum), what are they good for and how do you grow them at home?
Chilli peppers are the fruits of various pepper varieties (Capsicum annuum) known for their hot taste, which comes from the compound capsaicin. As well as adding heat to dishes, chilli peppers also have medicinal properties – they are used to stimulate circulation, speed up the metabolism and strengthen immunity.
Nutritionally, they are rich in vitamins C, A and B6, minerals such as potassium and iron, and capsaicin, which shows antioxidant and anti-inflammatory properties.
