What highly irritating compound forms when *Anemone* tissue is crushed or damaged?
Answer
protoanemonin
The primary irritant chemical constituent responsible for many of the adverse reactions associated with fresh Anemone species is protoanemonin. This compound is generated specifically when the plant tissue is subjected to mechanical stress, such as crushing or damage. Protoanemonin is known for its corrosive nature, causing significant irritation to sensitive tissues like the skin, mucous membranes lining the digestive tract, and internal membranes, frequently resulting in observable effects like blistering or burning sensations upon contact. This chemical hazard is the principal reason why fresh material requires extreme caution in any preparation context.
