Datura is a genus of flowering plants in the nightshade family, known in Britain as thorn apple and elsewhere as jimsonweed or devil's trumpet. Its trumpet-shaped flowers and spiny seed pods have earned it a long and uneasy place in folklore, and it carries historical and cultural significance in Ayurveda and Hinduism. It was used historically in traditional medicine, particularly in India, where it holds cultural and ritual weight.

This article looks at what tradition claims, what history records, and what is actually known. One point sits above everything else: Datura is a tropane-alkaloid plant that can kill, and nothing here is an invitation to grow, harvest, burn, smoke, eat or apply it. We cover it because readers ask about it and because the folklore is genuinely fascinating — but the practical blend suggested below contains no Datura at all.

What the tradition says

Traditionally, psychoactive use of Datura has been associated with witchcraft and sorcery in many cultures, including the Western world. Certain common Datura species have been used ritualistically as entheogens by some Native American groups. In traditional cultures, detailed knowledge of the plant was considered critical to minimising harm — which itself hints at how narrow the margin was.

Eliphas Levi inferred that witches' ointments contained opiates, green hemp pith, Datura stramonium, or laurel-almond. The word to notice is inferred: Levi was writing in the nineteenth century, reasoning backwards from older reports rather than working from any laboratory analysis. Michelet, writing about the witch of the Middle Ages, described a man fuddled with a baleful draught of datura or belladonna who became entranced, losing speech and motion but keeping sight. Elsewhere Michelet wrote that thieves readily used such decoctions, and that two victims in Aix fell into extraordinary delirium and spent a whole night dancing naked in a graveyard. These are historical claims and anecdotes, not verified case notes.

Historical context

Datura has been used for centuries in some cultures as a poison. A group called the Thugs, described as devotees of an Indian religious cult who strangled or poisoned victims in rituals devoted to the Hindu goddess Kali, were alleged to employ Datura in poisonings, using it to induce drowsiness or stupefaction to make strangulation easier. The words reportedly and alleged matter here; much of what was written about the Thugs came from colonial administrators with their own purposes.

Datura plants have also been used as a traditional medicine in many Asian countries, and Datura and Brugmansia have been used for their hallucinogenic effects in the United States and Europe. Modern poison-centre data from Taiwan gives a sobering picture: using Datura or Brugmansia for a medicinal purpose without consulting a Chinese medicine practitioner was the most common reason for poisoning, accounting for 81.2% of cases, while only 2% of patients were poisoned after medicinal use associated with a practitioner's prescription. That gap is the whole story in two numbers.

The ingredient and the practice

Datura is a genus of annual and perennial plants in the nightshade family, with large trumpet flowers, often white or violet, and seed pods covered in spines. The parts most often named in folklore and in older medical writing are the leaves, seeds and flowers, with the seeds and flowers carrying the heaviest reputation. In historical and traditional settings it appears as dried leaf, powdered seed, an infusion, a decoction, a fat or oil-based ointment, a burning incense, and occasionally as a smoked material — the last of these being especially dangerous, since smoke carries the alkaloids into the lungs. All of these forms are described here as a record of what people did, not as options to try.

Traditional associations

• Thorn apple, jimsonweed and devil's trumpet are all common names attached to Datura species.
• It belongs to the nightshade family and contains tropane alkaloids such as scopolamine and hyoscyamine.
• Folklore links it with witchcraft, sorcery and the witches' ointments described by nineteenth-century occult writers.
• Some Native American groups used certain species ritualistically as entheogens.
• It has a documented history as a poison as well as a traditional medicine.
• In Ayurveda and Hinduism it carries cultural and ritual significance.

How different traditions vary

The sources do not agree, and it is worth saying so plainly. Levi's claim about witches' ointments is an inference, not a recipe recovered from a trial record. Michelet's accounts are vivid literary history rather than clinical documentation. Broad reference works describe Datura as a traditional medicine and a ritual entheogen, while clinical poison-centre data describes it mainly as a cause of serious poisoning when used without supervision. Both can be true at once: a plant can hold deep cultural meaning and still be a genuine hazard. Where a tradition insists that only detailed, inherited knowledge makes the plant manageable, that is a warning dressed as a compliment.

Practical use

Because Datura cannot be used safely in any form — not burned, not smoked, not infused into oil, not applied to skin — the practical suggestion here is a substitute. In folk-magic terms the plant's reputation is one of thresholds, boundaries and hard limits, so a blend built around clear, protective aromatics does the same symbolic job without the risk. Think of it as a stand-in: the meaning is kept, the plant is not. If anyone has ingested or inhaled Datura, treat it as a medical emergency and contact 999 or NHS 111 straight away.

A simple diffusion blend for boundary and protection work: 40% lavender essential oil, 25% rosemary, 20% sweet orange and 15% cedarwood. Add it to a diffuser with water according to the manufacturer's instructions, in a ventilated room, and keep it away from pets and small children. If you would rather work with something physical than aromatic, a sealed jar of dried rosemary, bay leaf and a few cloves, kept closed and labelled, serves as a charm in the same folk tradition. Never add Datura to either, and never burn Datura as incense — the smoke is hazardous.

Safety

What is and is not scientifically established

What is well established is the harm. Datura and Brugmansia contain tropane alkaloids, and antimuscarinic toxicity from these plants is a recognised clinical picture, documented in poison-centre analyses such as the Taiwan study cited above. The finding that unsupervised medicinal use accounted for the large majority of poisonings, while practitioner-supervised use accounted for very few, is a real and useful observation about context and dose.

What is not established is any safe home dose, any reliable ritual dose, any spiritual or magical efficacy, and any therapeutic benefit from using the plant yourself. The folklore about flying ointments, entranced thieves and graveyard dancing is folklore and history, not evidence. No source here shows that Datura can be used safely outside a tightly controlled professional context, and none of it should be read as encouragement.

Questions people ask

Can I burn Datura as incense?

No. Burning releases alkaloids into the smoke, and inhaling them is dangerous. We do not include Datura in any incense, diffusion or charm blend, and the substitute blend above is designed to fill that role instead.

Is Datura the same as Brugmansia?

They are closely related but separate genera, and both are associated with antimuscarinic toxicity. Sources often discuss them together because the poisoning picture is so similar.

Why does Influance mention Datura at all?

Because readers ask about it, and because it appears constantly in the historical and folk-magic record. We cover the tradition honestly while making clear that the plant itself is not something we will suggest using.
