This preparation, transmitted orally in local traditions, requires professional advice before use due to the lack of precise data on safe dosages. Dosage must be validated with a healthcare professional or recognized pharmacopoeia before use.
The bark is shade-dried then finely ground to obtain a powder, sometimes mixed with honey or warm water according to reported traditional uses. It is recommended to consult a practitioner before any use, as the margin between traditional use and risk is not clearly established. Dosage must be validated with a healthcare professional or recognized pharmacopoeia before use.
Crateva magna is found primarily in the wild near watercourses and wetlands of South and Southeast Asia; its dried bark can sometimes be found at herbalist shops specializing in traditional Asian plants.
