What are the pharmacological activities of Datura stramonium?
This plant has anticholinergic, hallucinogenic, sedative, anticonvulsant, and bronchodilator pharmacological activities derived from its high concentrations of tropane alkaloids. These alkaloids, such as atropine and scopolamine, act primarily by blocking acetylcholine receptors in the nervous system. This mechanism facilitates its use as a bronchodilator for respiratory issues while simultaneously inducing profound sedative and anticonvulsant effects. However, the potent disruption of neurotransmission also produces intense hallucinogenic experiences that can lead to delirium. Due to these powerful and unpredictable interactions, the plant is handled with extreme caution in clinical and toxicological contexts.
According to a study published by "Orvosi hetilap", Datura stramonium contains alkaloids, which are mostly atropine. The consumption of any part of the plant causes atropine intoxication and anticholinergic delirium. This plant is seemingly becoming popular as a hallucinogenic drug because it can result in hallucinations. The study discusses the symptomatology, diagnosis, differential diagnosis, and therapy of Datura intoxication.
The primary pharmacological activities of this plant are shown in the list below.

What medicinal compounds this plant contains?
This plant contains a potent group of tropane alkaloids, specifically the belladonna alkaloids atropine, hyoscyamine, and scopolamine. These chemical compounds act as anticholinergic agents by inhibiting the action of acetylcholine in the nervous system. While these substances have significant medicinal applications in treating certain spasms and neurological conditions, they are also highly toxic in large doses. Medical professionals carefully regulate the extraction of these alkaloids to ensure patient safety during therapeutic use. Careful measurement is essential because the concentration of these compounds can vary greatly between individual plants.
According to a study published by "Life (Basel, Switzerland)", Datura stramonium contains the medicinal alkaloids scopoalamine and atropine, which possess anticholinergic properties. The production of these alkaloids in leaves and roots can be affected by methyl jasmonate at a concentration of 150 µM, which increases their accumulation. Conversely, applying methyl jasmonate at 300 µM results in an adverse effect on the production of these compounds. The study also analyzed three critical enzymes in the biosynthetic pathway, specifically PMT, TR1, and h6h. These results suggest that methyl jasmonate can be used to regulate the biosynthesis and accumulation of scopoalamine and atropine in Datura stramonium.
The primary medicinal compounds of this plant are shown in the list below.
- Atropine
- Hyoscyamine
- Scopolamine
- Tropane alkaloids
- Anticholinergic alkaloids
