Evidence notes
Limited human clinical trials with modest sample sizes. Some in vitro and animal studies support traditional uses, but controlled RCT evidence in humans is sparse. Traditional use in Amazonian medicine is well-documented but does not establish clinical efficacy by modern standards.
Grade C: Mostly observational or small trials; mechanism is plausible but unproven at scale.
