(CNN) Even as global health authorities warn of potential dangers and misinformation about an untested natural therapy, the leader of one African country is pushing a traditional tonic to try to treat coronavirus patients across the continent. But the World Health Organization, or WHO, has warned against using untested herbal therapies to treat coronavirus patients without first "establishing their efficacy and safety through rigorous clinical trials" in step with global standards. Along with a photo of himself sipping an amber-colored fluid from a bottle, Rajoelina announced last month that scientists from the country's research institute had developed Covid Organics, or CVO, to treat Covid-19. The WHO country office has "initiated" a conversation with authorities in Madagascar to test and assess the tonic, officials said. Researchers are working on treatment options for Covid-19, and at least 110 potential vaccines are in development, according to WHO.
