Thank you for your question, lybrate-user! hypertension can be easily managed at this age with the help of ayurveda and natural lifestyle. However, your concern for your father's general weakness (as presumed by the medicine you've seek suggestion for) can be resolved by taking Dr. Vaidya's herbofit which not only revitalises the body but also helps it gain the fitness needed by the body. For hypertension, I suggest you to continue the regular prescription and start pranayama for a stress-free life.
