There is evidence that suggests a relationship among free radicals, brain injury, and brain functionality. The scavenging of free radicals as a possible mechanism for the improvement in intelligence by Student Rasayana (SR) was explored in this study on the effect of SR on lipid peroxidation and lipoxygenase activity. SR inhibited enzymatic- and nonenzymatic-induced rat liver microsomal lipid peroxidation in a concentration-dependent manner (p<0.05). SR also inhibited soybean lipoxygenase-induced LDL oxidation in vitro (p<0.05). In vivo, SR inhibited toluene-induced rat brain microsomal lipid peroxidation (p<0.05).

An interesting finding in this study is that an alcoholic extract of SR increased in vitro a metabolite of arachidonic acid which enhances long-term potentiation, a process associated with learning.

Thus, SR may protect brain functions and increase intelligence through scavenging of free radicals and/or increasing certain metabolites of arachidonic acid.

Student Rasayana is now called Intelligence Plus.
