Claim:
A dosage form comprising at least one non-acidic extract derived from a Boswellia species in an amount effective to enhance a cognitive function in an individual in need thereof, said non-acidic extract being prepared by a process comprising: i) extraction of a Boswellia gum resin with a water-immiscible non-polar solvent to produce a non-polar solvent extract; ii) washing the non-polar solvent extract with aqueous alkali to remove boswellic acids from the non-polar solvent extract to produce an intact Boswellia oil (BOIL); and iii) subjecting said BOIL to distillation to produce a non-volatile Boswellia oil component and a Boswellia volatile oil (BVOIL) recovered as a distillate from said distillation; wherein said non-acidic extract is selected from the group consisting of the non-volatile Boswellia oil component, BVOIL, BOIL, and a mixture thereof.
