Strong evidence
StrongAn approved medicine, or consistent good-quality trials and reviews.
Corkwood
Duboisia myoporoides
Scopolamine, the plant's main alkaloid, is an approved medicine for preventing motion sickness; the US FDA has approved a transdermal scopolamine patch that reaches protective levels in 6–8 hours and lasts up to 72 hours. This evidence is for the purified drug, not the leaf.

Deadly nightshade
Atropa bella-donna
Scopolamine (hyoscine), a related alkaloid of the nightshade family, reduced motion-sickness nausea compared with placebo in a 2024 meta-analysis of 20 studies (risk ratio 0.35).

Devil's trumpet
Datura metel
Not the plant but its alkaloid: scopolamine (hyoscine), from Datura and related nightshades, is a licensed medicine; a 1.5 mg transdermal patch lasting 72 hours prevents motion sickness, with efficacy near 90% in controlled trials.

Toloache
Datura inoxia
Not a use of the plant: scopolamine (hyoscine), a tropane alkaloid of Datura, is an established medicine. A Cochrane review of 14 RCTs (1,025 people) found it more effective than placebo for preventing motion sickness.
