#abstract says Cecropia pachystachya (#ambay) is effective against P. falciparum malaria in mice; the active ingredient is tormentic acid; roots have the best therapeutic index (i.e. lowest toxicity at active dose). #herbal #medicine

This seems particularly interesting to me for #3D printing because alginate gels fast when there’s enough ionic calcium present, which can be controlled by temperature.
