ABSTRACT
The term rasayana in Ayurveda is mentioned way back in the Caraka Samhita as an agent that confers long life, youthfulness, freedom from disease, a strong body, maintenance of faculties leading to a gleaming complexion, powerful voice, good eyesight, acuity of mental faculties, and acute hearing-in effect retaining one’s faculties throughout one’s life.1 With such an enticing prospect, it is little wonder that this concept has aroused great interest in interpreting these outcomes in modern scientific terms.
