What is Jimsonweed / Datura?
Jimsonweed (Datura stramonium), also known as devil’s trumpet, thorn apple, or moonflower, is a highly toxic plant belonging to the nightshade family (Solanaceae). Native to Central America but now found worldwide, this annual herb contains potent tropane alkaloids including scopolamine, atropine, and hyoscyamine. While historically used in traditional medicine and shamanic practices, jimsonweed is classified as a dangerous substance due to its unpredictable and potentially fatal effects. The plant is banned for human consumption in many countries and is not approved by the FDA as a dietary supplement.
Health benefits & uses
Evidence Grade: Limited/Historical Only
Jimsonweed has no scientifically proven health benefits and should not be used for medicinal purposes. Historically, various cultures used small amounts of Datura species for:
- Pain relief (topical applications)
- Respiratory conditions like asthma
- Sleep disorders
- Spiritual or hallucinogenic experiences
However, modern scientific research has not validated these traditional uses, and the extreme toxicity of the plant far outweighs any potential therapeutic benefits. All historical medicinal uses are now considered obsolete and dangerous due to the narrow margin between an “active” dose and a lethal dose.
How it works
Jimsonweed’s effects result from its tropane alkaloids, which act as competitive antagonists of muscarinic acetylcholine receptors in the central and peripheral nervous systems. This anticholinergic activity blocks normal nerve transmission, leading to:
- Disruption of normal brain function
- Impaired memory formation
- Altered perception and hallucinations
- Interference with vital bodily functions including heart rate, breathing, and temperature regulation
The alkaloid content varies dramatically between plants, plant parts, growing conditions, and harvest times, making dosing impossible to predict and contributing to frequent overdoses and fatalities.
Dosage
WARNING: There is no safe dosage for jimsonweed. No recommended daily allowance (RDA) or upper limit (UL) exists because this plant should never be consumed. The difference between a psychoactive dose and a lethal dose is extremely narrow and unpredictable. Even experienced users cannot determine safe amounts due to variable alkaloid concentrations. Medical supervision cannot make jimsonweed use safe, as there are no established protocols for its medicinal use in modern healthcare.
Food sources
Jimsonweed is not a food and should never be consumed. The plant may occasionally contaminate agricultural products or be mistaken for edible plants, leading to accidental poisoning. All parts of the plant are toxic, including:
- Seeds (highest alkaloid concentration)
- Leaves
- Flowers
- Stems and roots
No commercial food products legitimately contain jimsonweed. Any supplement claiming to contain Datura should be avoided entirely.
Safety & side effects
Jimsonweed is extremely dangerous and can cause severe poisoning or death even in small amounts. Common effects include:
- Severe hallucinations and delirium
- Hyperthermia (dangerous elevation in body temperature)
- Rapid heart rate and irregular heartbeat
- Respiratory depression
- Seizures
- Coma and death
- Dry mouth and skin
- Dilated pupils
- Confusion and agitation
Emergency medical treatment is required for any suspected jimsonweed exposure. Long-term effects may include permanent neurological damage and psychological trauma.
Interactions
Jimsonweed has dangerous interactions with numerous substances:
- Anticholinergic medications: Additive toxicity with drugs like antihistamines, tricyclic antidepressants, and antipsychotics
- Central nervous system depressants: Increased risk of respiratory depression with alcohol, benzodiazepines, and opioids
- Stimulants: Unpredictable cardiovascular effects
- All other supplements and medications: Potential for dangerous interactions due to impaired metabolism and organ function
Who should be cautious
Everyone should avoid jimsonweed entirely. It is particularly dangerous for:
- Children and adolescents
- Pregnant and breastfeeding women
- Individuals with heart conditions
- People with mental health disorders
- Those taking any medications
- Individuals with liver or kidney disease
- Anyone with a history of seizures

Can jimsonweed be used safely for spiritual purposes?
No. Despite historical use in some spiritual traditions, there is no safe way to use jimsonweed. The unpredictable alkaloid content makes overdose highly likely, and numerous deaths have been reported from spiritual or recreational use.
What should I do if someone has consumed jimsonweed?
Immediately call emergency services (911 in the US). Do not induce vomiting. Keep the person calm and in a safe environment while waiting for medical help. Bring any remaining plant material to help medical professionals with identification and treatment.
Are there safer alternatives for the supposed benefits of jimsonweed?
Yes. For any health concern that might lead someone to consider jimsonweed, safe and effective alternatives exist. Consult with healthcare providers about evidence-based treatments for pain, sleep disorders, respiratory issues, or mental health concerns.
Can jimsonweed poisoning be treated?
Medical treatment focuses on supportive care and managing symptoms. Physostigmine may be used as an antidote in severe cases, but recovery depends on the amount consumed and how quickly treatment begins. Some effects may be permanent.
