Datura
Datura · Accepted scientific name
Scientific literature: Very Sparse (4 studies) · ★☆☆☆☆
Datura is a genus of plants containing potent alkaloids such as scopolamine, atropine, and hyoscyamine, alongside various flavonoids. Every part of the plant, including the leaf, seed, root, and stem, can be utilized in preparations like extracts, crude drugs, or infusions of dry stramonium leaves. While these components have historical uses in treating conditions like asthma, abscesses, and boils, they are notoriously dangerous. The plant's psychoactive and hallucinogenic properties carry extreme risks, including teratogenic effects and frequently fatal outcomes. Consequently, extreme caution is required when handling any part of this highly toxic species.

Identification
Biological Activities
Datura is a genus of plants within the Solanaceae family that possesses a complex range of pharmacological properties. Due to its various bioactive phytochemical constituents, the plant is recognized for its potent psychoactive effects. In several cultures, its flowers and seeds are specifically utilized for their hallucinogenic properties during ritualistic or voluntary intoxication. However, these powerful effects come with significant risks, as the genus is also classified among plants suspected of having teratogenic activity. Consequently, while Datura offers potential for medicinal discovery, its toxicity and biological impact require careful investigation.
Compounds
Datura is a diverse genus of medicinal plants recognized for its complex chemical profile and significant bioactivity. The plants are known to contain various potent tropane alkaloids, specifically hyoscyamine, scopolamine, and atropine. Beyond these alkaloids, phytochemical screenings have identified the presence of flavonoids and cardiac glycosides within the species. These diverse secondary metabolites contribute to the plant's wide range of pharmacological and antioxidant properties. Consequently, the unique chemical composition of Datura makes it a valuable subject for both therapeutic development and toxicological study.
Conditions
Datura possesses diverse applications, such as using its extract to treat late blight in potato plants by inducing disease resistance. Historically, the plant has been utilized as a natural drug to treat asthma, boils, and abscesses. While it offers these medicinal benefits, it is also associated with significant risks in human toxicology. Specifically, Datura species have been identified as responsible for a notable portion of plant-related fatal outcomes.
Preparations
Datura is prepared as an extract used to study metabolic effects in rats and to induce disease resistance in potatoes. It is also prepared as crude drugs, which allows for the chromatographic analysis of specific alkaloids like hyoscyamine and scopolamine. Historically, the plant has been prepared as fumitories and psychoactive infusions for traditional medicinal and religious purposes. Furthermore, infusions of dry leaves of stramonium have been identified as a source of acute poisoning characterized by hallucinations. Finally, Datura is prepared as nanoparticles, specifically silver nanoparticles, which demonstrate significant antimicrobial and cytotoxic potential in photodynamic therapy.
Parts used
Datura is a versatile plant that contains various active components found throughout its different morphological structures. Research indicates that the leaves and stems can be used to mediate silver nanoparticles with significant antimicrobial and cytotoxic potential. The seeds of the plant are also highly potent, capable of inducing serious neurological effects and altering metabolic activities in biological models. Furthermore, the rootzone of certain species hosts unique microbial communities that may influence the production of bioactive molecules. Ultimately, whether through the ingestion of leaves or the study of roots, every part of the Datura plant plays a distinct role in scientific and medical investigations.
