Sweetgrass has many ceremonial, practical and sacred uses in Native culture and researchers have confirmed that the plant acts as a bug repellent. Research being presented at a meeting of the American Chemical Society today shows that Hierochloe odorata works best against mosquitoes. The plant's effectiveness is comparable to that of DEET, a chemical used in commercially-available bug sprays. “It gives off a sweet aroma that repels mosquitoes," researcher Charles Cantrell said of the plant in a press release. Cantrell's study was partially funded by the U.S. military through the Armed Forces Pest Management Board. DEET was initially developed in 1994 for military use. Get the Story:
