The Strange Beauty Trend That Used a Deadly Plant

Details

Long before modern cosmetics and safe eye treatments, people experimented with natural plant extracts in pursuit of beauty ideals. One of the most unusual examples involves belladonna, a toxic plant also known as deadly nightshade. It contains natural chemicals that affect the nervous system in the eyes, leading to a strong pupil dilation effect. Historically, larger pupils were linked with attractiveness and youthful appearance, so some people used diluted plant extracts around the eyes in an attempt to achieve this look. The effect was not just cosmetic, as the same compounds that widened the pupils could also blur vision and interfere with normal focusing. Modern science explains that these plant chemicals block certain nerve signals that normally cause the pupil to contract, allowing it to remain enlarged for an extended period. Today, safer synthetic versions of these compounds are used in controlled medical settings, especially in eye examinations, where doctors temporarily widen pupils to examine the inside of the eye. While the beauty use of belladonna has long disappeared, it remains a striking example of how historical beauty standards sometimes led to risky practices driven by the desire for certain facial features.
