परिचयः ॥ Introduction

Rasayana is defined as the means of procuring the best qualities of different dhatus (धातवः। body building tissues) in sharira (शरीरम्।). Rasayana therapy also improves longevity, memory, intelligence, health, youth, complexion, voice, motor power and sensory responsiveness. According to Ayurveda, the body fluid named 'Rasa' is responsible for transport of nutrients to all other tissues that hold the entire body and give its necessary strength. Disease develops in body only when the Dhatus (body tissues) lack strength and thus create seat for vitiated Doshas ultimately leading to development of disease. Thus, proper nourishment, strength and quantity of Dhatus in one's body is essential in order to combat diseases. Rasayana therapies are designed with this aim to improvise the strength of body tissues. Supreme quality Dhatus in addition to provide defense against diseases, help to enhance the other faculties like cognition, complexion, immunity, physical strength etc. Thus, Rasayana is also recognized as rejuvenation therapies that include use of herbs, food, specialized dietary regimen, special health-promoting conduct/behavior and other drugs.

व्युत्पत्तिः ॥ Etymology

The word "Rasayana" is composed of 2 terms.

Place of Rasayana in Ayurveda

Rasayana tantra is a specialty of Ayurveda. It is also known as Jarachikitsa. Various methods to prevent premature ageing, achieve longevity (by preventing diseases and preserving the health), increase the strength, endurance and immunity are discussed under this branch of Ayurveda. The word जरा । ‘Jara’ means Ageing or senility. Thus, Jarachikitsa also signifies the specialty treatments in Ayurveda for diseases occurring in old age. Therefore, this branch is commonly referred to as Geriatrics but its scope is not limited to the subject of Geriatrics in conventional medicine.

Jara : The alternative term for Rasayanatantram

Ayurveda has considered Jara or vardhakya as a natural and inevitable process as well as a Swabhavaja vyddhi (natural disease). Etymologically, the term Jara comprises of Jr+Ana+ Tap.

The term Jara has been derived from the Sanskrit root,

"Irisb vayohanow" which can be explained as "Vayah krta slata mamsadya vastha visesa" which means the muscles and other tissues are loosened under the influence of aging. Totally this term indicates of the' loss' in the period of life span.

A synonym of Jara "Visrasa" is derived from the word "Sramsu adahpatane" which means a degradation / retardation in the physical, physiological and psychological well-being.

Benefits of Rasayana

It was well known to Ayurveda physicians that the delicate cellular machinery of the body suffers from trauma, resulting in wear and tear on different body structures and the deterioration of the functional capacity. For this, procedures of revitalization and rejuvenation (Rasayana therapy) were adopted to increase the power of resistance to disease, these procedures retarded advancement of aging also.

Pretreatment for Rasayana

‘Rasayana’ enhances the functions of the whole body system. ‘Rasayana’ treatment for rejuvenation is done after the system is thoroughly cleansed by ‘Panchakarma’ therapy. ‘Panchakarma’ is essentially a pretreatment equipping the body tissues for ‘Rasayana’ therapy. Shushruta observed that a person, whose system is not been previously cleansed by proper purification remedies, cannot expect good results with ‘Rasayana’ treatment. [Needs editing]
