• Jimson weed (Datura stramonium) grows throughout the world and has been known as a hallucinogenic plant for centuries. It has reportedly been used by Shamans and native peoples during sacred rituals. In India, the smoke of jimson weed has been used to treat asthma.
• Jimson weed may cause extreme toxicity including death. Even very small amounts may cause death. Jimson weed is therefore not used medicinally today, although some alkaloids from jimson weed are approved drugs.
• In early research, jimson weed has been studied for asthma and chronic bronchitis, however, clinical evidence supporting any safe or effective use of jimson weed is lacking at this time.

• Antibacterial, antimicrobial, antitumor, asthma, colorectal cancer, hallucinogenic, insecticide, muscle spasms, Parkinson's disease (saliva production control), sedative, whooping cough.

Adults (18 years and older)

• There is no proven safe or effective dose for jimson weed. Jimson weed may cause extreme toxicity.

Children (under 18 years old)

• There is no proven safe or effective dose for jimson weed, and use in children is not recommended. Jimson weed may cause extreme toxicity and even small amounts may cause death in children.

Allergies

• Avoid with a known allergy or hypersensitivity to jimson weed, its constituents, other Datura species, or other plants in the nightshade family, such as tobacco, peppers, eggplant, potatoes, and tomatoes.

Side Effects and Warnings

• Jimson weed may cause extreme toxicity including death. Even very small amounts may cause death.
• Jimson weed may cause rapid heart rate, life threatening abnormal heart rhythm, high blood pressure, respiratory arrest, psychosis, delirium, disorientation, hallucinations, seizures, amnesia, coma, and may worsen neurological disorders.
• Jimson weed may increase the risk of bleeding. Caution is advised in patients with bleeding disorders or taking drugs that may increase the risk of bleeding. Dosing adjustments may be necessary.
• Jimson weed may also cause liver damage, kidney damage, difficulty urinating or urinary retention, and blurred vision.

Pregnancy and Breastfeeding

• Jimson weed is not recommended in pregnant or breastfeeding women due to potential for extreme toxicity.

Interactions with Drugs

• Jimson weed may increase the risk of bleeding when taken with drugs that increase the risk of bleeding. Some examples include aspirin, anticoagulants ("blood thinners") such as warfarin (Coumadin®) or heparin, anti-platelet drugs such as clopidogrel (Plavix®), and non-steroidal anti-inflammatory drugs such as ibuprofen (Motrin®, Advil®) or naproxen (Naprosyn®, Aleve®).
• Jimson weed may increase the amount of drowsiness caused by some drugs. Examples include benzodiazepines such as lorazepam (Ativan®) or diazepam (Valium®), barbiturates such as phenobarbital, narcotics such as codeine, some antidepressants, and alcohol. Caution is advised while driving or operating machinery.
• Jimson weed may alter blood pressure. Caution is advised in patients taking drugs that alter blood pressure.
• Jimson weed may have additive effects when taken with anti-cholinergics, beta-blockers, cardiac glycosides, antimicrobials, analgesics, antipsychotics, diuretics, stimulants, drugs used for the eye, drugs used to alter heart rate or heart rhythm, drugs toxic to the liver, or drugs with anti-asthmatic, anticancer, anti-seizure, or immune altering properties.

Interactions with Herbs and Dietary Supplements

• Jimson weed may increase the risk of bleeding when taken with herbs and supplements that are believed to increase the risk of bleeding. Multiple cases of bleeding have been reported with the use of Ginkgo biloba, and fewer cases with garlic and saw palmetto. Numerous other agents may theoretically increase the risk of bleeding, although this has not been proven in most cases.
• Jimson weed may increase the amount of drowsiness caused by some herbs or supplements.
• Jimson weed may alter blood pressure. Caution is advised in patients taking herbs or supplements that alter blood pressure.
• Jimson weed may have additive effects when taken with anti-cholinergics, beta-blockers, alkaloids, cardiac glycosides, antimicrobials, analgesics, antipsychotics, diuretics, stimulants, herbs or supplements used for the eye, herbs or supplements used to alter heart rate or heart rhythm, herbs or supplements toxic to the liver, or herbs or supplements with anti-asthmatic, anticancer, anti-seizure, or immune altering properties.
