Hello; I just wanted to mention that a friend who had just returned to Australia from Papua New Guinea came down with a chronic attack of Malaria (vivax) and, as I still had the original bottle of Demal 200 in my fridge I asked him to try it. Well he was so sick he would try anything, and yes he was completely cured in 6 days, he had been suffering regular reccurrences of Malaria for 3 years, unfortunately he used the whole 15ml bottle so I need to order some more. Kind Regards Richard McKeown
