Use in Chilean folk medicine
In the Los Lagos Region of southern Chile R. spinosus is one of three plant species believed in local folk medicine to be antidotes to the anticholinergic poisoning caused by the dangerous hallucinogenic plant Latua pubiflora ( Solanaceae ). It is used by the shamans of the indigenous Huilliche people who employ Latua to enter trance in machitun healing rituals.
