Nettle is a perennial flowering plant belonging to the Urticaceae family, known for its painful stings upon contact. The distinguishing feature of nettle lies in its hollow stinging hairs, which inject a mixture of irritating chemicals when touched, including histamine, acetylcholine, and serotonin. These compounds trigger a painful, stinging sensation and can cause itching, redness, and swelling on the skin. Despite its sting, nettle has been used for various medicinal and culinary purposes throughout history.
Nettle is a perennial herbaceous plant belonging to the Urticaceae family, with common species like Urtica dioica. It is known for its serrated leaves and tiny hairs that contain irritants, including histamines and formic acid. These hairs act like hypodermic needles upon contact, injecting chemicals that cause a painful stinging sensation. The distinguishing characteristic is the presence of these stinging hairs, which can break upon contact, releasing substances that trigger an inflammatory response, leading to redness, itching, and discomfort. Protective clothing and caution are advised when handling nettles to avoid the painful stings caused by these microscopic structures.
