We have been living in S Africa for 6 years now and have taken nothing but Demal 200 and Hepatex when traveling on this continent. On a 4 month road trip through many southern African countries with our children again we relied, without exception on Demal 200 and Hepatex. My son then spent 5 months in India, Bangladesh and China and took both the above products on a daily basis. As they have no side effects they are a pleasure to take! I now recommend Demal to all our visitors and to our friends in South Africa when they travel to malaria affected regions. thank you!
