We originally used Demal200 back in 2004 through 2006 in a remote village setting of Papua New Guinea. We were missionaries in the Sepik Region with a very strong malaria presence. We worked with two other families who were using chloroquine and mefloquine. They all continually got malaria. We started as a family on mefloquine/larium but my wife started suffering with many side effects that scared us. We were recommended by a family member doing research for us about Blueturtlegroup and the demal200 product. Our kids were ages one, two, and four at the time and we never got malaria once. We ended up recommending Demal200 to many missionaries and many still use it. So, recently I went into the thick of the Amazon in a strong malaria area. We were in the State of Amapa again visiting a remote tribal group as I was hosting a missions trip. The missionaries there have had malaria too many times to count so I told them about Demal200 and used it while there and had no issues. I am a strong advocate of your product as I have firsthand experience of using it for long periods of time while malaria was prevalent with never having come down with malaria to date. Many thanks for your great product.
