Experimental evidence indicates that administration of Boswellia resin, known as olibanum or Frankincense, increases memory power. It is reported that beta boswellic acid, the major component of Boswellia serrata gum resin, could enhance neurite outgrowth and branching in hippocampal neurons. We therefore studied whether Boswellia treatment produces morphological changes in the superior region of cornu ammonis (CA1) in aged rats. ⋯ The total dendritic length of CA1 neurons was approximately 20 % larger in the experimental group compared to control. Results also indicated that the aged rats treated with Boswellia resin had more numerical branching density in the apical dendrites of CA1 pyramidal neurons. The results of the present study show that long-term administration of Boswellia resin can attenuate age-related dendritic regression in CA1 pyramidal cells in rat hippocampus.
