Andean tubers: traditional medicine and other applications

Tubers are a staple food in Andean highland communities, valued for their rich carbohydrate content with starch being the predominant component. Additionally their consumption is preferred for various health benefits, including anti-inflammatory effects, pain relief, digestive system improvement, diabetes management and wound healing, among others. Several studies have focused on Andean tubers such as Oxalis tuberosa, Tropaeolum tuberosum, Ullucus tuberosus, Arracacia xanthorrhiza and Smallanthus sonchifolius, revealing different compounds with pharmacological effects on humans and strengthening the immune system. Therefore, the objective of this review was to compile information from different databases such as Scopus and Web of Science on research conducted in the last decade on these tubers, highlighting their health benefits and potential for technological innovation for the benefit of the Andean communities that produce these crops. These tubers have been little marketed outside their production areas due to a lack of awareness. Although their applications have been limited, they have shown positive results, making them promising sources of health-beneficial phytochemicals. They could be used in technological developments to benefit health, particularly in addressing diseases that cause the most deaths.
