Background Indian traditional medicine practices use defined rasayana preparations to improve the quality of life in aged individuals. Amalaki Rasayana is one such rasayana prepared from the fruits of Phyllanthus emblica and is popularly used to prevent or treat various age related health conditions. Telomerase activity in the cells maintains telomere length and is implicated in ageing and various diseases wherein the shortening of telomere during ageing is controlled chiefly by the telomerase activity. Objective In the present study, we investigated telomerase activity and telomere length in the peripheral blood mononuclear cells of aged individuals administered with Amalaki Rasayana. Materials and methods Amalaki Rasayana was administered to healthy, aged (45–60 years) volunteers for 45 days after koshta shuddhi procedure. The telomerase activity and telomere length were analyzed on 0, 45th and 90th days of Amalaki Rasayana administration in peripheral blood mononuclear cells from these individuals and compared with age-matched placebo group and young volunteers (22–30 years). The data were compared between the groups. Results The results indicated an increase in telomerase activity with no discernible change in telomere length in the Amalaki administered participants. The comparison between young and aged participants revealed higher telomerase activity in young participants with no significant differences in telomere length. Conclusion The data indicate that the maintenance of telomere length is facilitated by an increase in telomerase activity upon rasayana administration in aged individuals and Amalaki Rasayana may prevent the erosion of telomeres over a period of time in aged individuals to promote healthy ageing.
