lmmunopotentiating agents are useful in enhancing resistance to infections in individuals whose immunocompetence
is compromised for one reason or another.
Because of the very wide spectrum of infectious and non·infectious diseases for which preparations
from Azadirachta indica are said to be efficacious, it was suspected that a general immunopotentiating
ability could be part of the mechanisms by which it ameliorates so many disease conditions. Using
the haemolytic plaque technique, an aqueous extract of Azadirachta indica stem bark was shown to
enhance the immune response of BALB/C mice to sheep red blood cells in vivo.
