A 'nettle' is a plant, often of the genus Urtica, known for its stinging hairs that cause irritation upon contact. These hairs inject histamine and other chemicals into the skin. However, when cooked, nettles lose their sting and become a nutritious food source. Think of it as a plant with a built-in security system. Itβs not as inviting as a rose, but has its own defense.
