The Neem tree has long been the overstood prevention of malaria. It acts a disinfectant for the liver, where malaria develops. In the presence of the Neem, malaria is not given the opportunity to develop and is ultimately broken down. The Neem is the most common tree in Ghana and a branch with some leaves is readily available to boil as tea. It is suggested that it is taken once a week, as excess can weaken the liver.
BTW: Had a cerebral malaria attack the other night and luckily had the EPFX unit in house. At 4AM I ran the test and then treated this with frequency looking at my results the value of NEEM in the SCIO db jumped through the roof (means effective) during that test as well. Will get some NEEM ASAP to stop further development.
