I just wanted to say how impressed we were with the product. We used it in conjuction with Malaria tablets in Africa, but used it on it's own in Asia (as there were no tablets we wanted to take). I had complete confidence in the product and some of the tour leaders we met in Africa were also impressed and wanted to promote it to the management of Kumuka [tours]. The tour leaders tend not to take Malaria tablets as they often work year round, rendering the medicine useless, and they felt that Demal was a way to prevent them getting malaria and quite possibly promoting to the African people. Perhaps there may be a way to get this product out there?
