Glinus lotoides is native to Eurasia and Africa and has become widespread in tropical, subtropical, and warm-temperate areas worldwide. Several varieties have been described, but their delimitations are unclear and need further investigation. The vernacular name “damascisa” is applied to this species, as well as several other plants, which are used in Africa for treatment of diabetes and skin ailments (A. El-Hamidi et al. 1967). In India, the species is used as treatment for diarrhea, boils, and abdominal diseases, as well as weakness in children (K. R. Kirtikar and B. D. Basu 1935). Antihelmintic properties are reported for G. lotoides from several African studies (B. Abegaz and B. Tecle 1980; G. Broberg 1980).
