CHILCUAGUE
Mexican medicinal plant (Heliopsis longipes) whose root alkamides provide analgesic, stimulant, and vasodilatory effects.
Three published studies confirm bioactivity of Heliopsis longipes root and its main alkamide affinin. Cilia-López et al. (2010) demonstrated analgesic activity comparable to ketorolac and CNS stimulation comparable to caffeine in mouse models. García-Badillo et al. (2021) showed dose-dependent proangiogenic effects of affinin and ethanolic root extract both ex vivo and in vivo. Ruiz-Castillo et al.) characterized the alkamide profile across phenological stages, finding that vasodilatory activity peaks during fructification. Evidence is limited to preclinical animal and ex vivo models; no human clinical trials have been published. Traditional use in Mexican medicine for dental and muscle pain spans centuries but lacks formal pharmacokinetic characterization in humans.
