Safety

Who should avoid it

  • Don't use datura if you have glaucoma, an enlarged prostate, a fast or irregular heartbeat, a blocked or paralyzed bowel, a narrowed stomach outlet (pyloric stenosis) or fluid on the lungs.[1]Study

Side effects

  • People who take datura recreationally for its hallucinogenic effects have been seriously poisoned.[1]Study

Pregnancy

  • The review warns that exposure before birth may cause lasting harm to the baby. Don't use it while pregnant.[1]Study

Toxicity testing

  • Every part of datura is poisonous, and the seeds are the most poisonous. Drying or boiling doesn't destroy the poison. Poisoning can cause dry mouth and skin, widened pupils, blurred vision, a fast heartbeat, fever, confusion, hallucinations, seizures, coma and death. Get emergency help if someone may have eaten it.[1]Study

Contamination

  • Datura seeds can get mixed into grain and bean harvests. In Uganda in 2019, contaminated food aid poisoned 293 people and 5 died. Symptoms included confusion, dizziness, diarrhea, vomiting, seizures and hallucinations, starting 2 to 12 hours after eating.[2]Study

What does the research say?

Traditional use

These are traditional uses, not proven treatments.

  • In Ayurveda, datura has been used for:

    • wounds, ulcers, burns and swellings (the bark, applied to the skin)
    • rheumatism and sciatica pain (as an ointment)
    • asthma and sinus problems (the leaf, taken by mouth, or smoked)
    • fever, inflammation and toothache

    The seeds have also been smoked for their hallucinogenic effect, and the plant is used in religious rituals.[1]Study

Laboratory & animal research

Lab and animal results show what might be worth studying in people. They don't show that the herb has these effects in humans.

  • In lab tests, seed extracts showed antioxidant activity and killed breast cancer cells. Leaf extracts killed some bacteria and repelled or killed mosquito larvae.[1]Study

    Technical detail: methanolic seed extract DPPH IC50 94.87 µg/mL; MCF-7 IC50 113.05 µg/mL; larvicidal against Aedes aegypti, Anopheles stephensi and Culex quinquefasciatus.

Research in people

  • The 2021 review mentions a study in which people with mild asthma inhaled smoke from datura cigarettes and their airways opened slightly. It gives no details of how many people took part, and no controlled trials in people were found.[1]Study

In short

Every part is poisonous, and drying or boiling doesn't make it safe.
