Exploring the ethnopharmacological journey from ancient poison to modern medicine
Imagine a plant so dangerous that ancient civilizations named it after the Greek fate who cuts the thread of life, yet so sought-after that Renaissance women used it to enhance their beauty. Atropa belladonna, commonly known as deadly nightshade, presents one of nature's most fascinating paradoxes—both lethal poison and healing remedy 7 8 .
Theophrastus recommended mandrake for treating wounds, gout, and sleeplessness. Pliny the Elder documented its anesthetic use 8 .
Associated with witchcraft and magic, used in "flying ointments" to induce hallucinatory states 7 .
The primary alkaloid in Atropa belladonna, it acts as a competitive antagonist at muscarinic acetylcholine receptors in the autonomic nervous system 6 .
A racemic mixture of d- and l-hyoscyamine, this compound forms either during extraction of the plant material or after ingestion 2 .
Modern investigations have revealed a broad spectrum of biological and pharmacological activities associated with Atropa extracts 1 :
Studies have shown anti-inflammatory potential of Atropa acuminata, with ability to modulate T-helper cytokines and inflammatory mediators in arthritic tissues 1 .
Antimicrobial properties against resistant pathogens, with significant activity against Pseudomonas aeruginosa 3 .

A 2021 study disrupted the hyoscyamine 6β-hydroxylase (H6H) gene, creating plants that produce high yields of hyoscyamine without generating anisodamine or scopolamine 6 .
Optimizing alkaloid pathways to enhance production of desired compounds 6 .
Investigating how multiple plant compounds work together rather than in isolation 9 .
The journey of Atropa from feared poison to valuable medicine exemplifies the complex relationship between humans and the plant kingdom. These plants remind us that nature's compounds are neither inherently good nor evil—their value depends on our understanding, dosage, and application.
The ethnopharmacological investigation of Atropa represents a compelling model for drug discovery—one that combines ancient wisdom with cutting-edge technology to address contemporary health challenges. In the delicate balance between toxicity and therapy, we find opportunities to transform historical fears into future healing.
