Yam (vegetable)
Dioscorea hispida
Dioscorea hispida is a plant traditionally not associated with any specific medicinal uses. Scientific evidence suggests potential applications in cosmetics, where extracts from this plant have shown stable enzyme inhibitory activities and minimal dermal irritation. Additionally, while studies involving other plants like Bauhinia malabarica indicate virucidal activity against various viruses, no direct evidence for Dioscorea hispida's antiviral properties has been reported. In another study, incorporating lemongrass essential oil into chitosan-Dioscorea hispida starch films enhanced their antimicrobial and antioxidant activities, highlighting its potential in biotechnological applications. Safety assessments of Dioscorea hispida tuber extract up to tested concentrations did not reveal any adverse effects or mutagenicity in acute toxicity and genotoxicity evaluations. No significant drug interactions have been recorded for this plant.
