Definition of belladonna

The word "belladonna" originates from the Italian language, where it translates to "beautiful woman." This name was given to the poisonous nightshade plant due to an ancient tradition in which women would use it to dilate their pupils, enhancing their physical beauty. The plant contains the potent alkaloid atropine, which acts as a parasympathetic blocker, causing constriction of the pupils, leading to a temporary dilation caused by the body compensating by overdilating them. However, consuming high doses of belladonna can lead to severe side effects and even death. The name "belladonna" reflects the dualities of this plant, as its beauty can hide its dangerous potential.
