The average span of an individual has increased in present times due to better quality of medical help and improved nutrition. Therefore the number of old people in the society has gone up. Rejuvenation or rasayana therapy, prescribed in Ayurveda, is meant to help improve the quality of lives of old people. Charaka, while defining the scope of this therapy, states that through it, the individual is endowed with longevity; memory; intellect; positive health; youthfulness; excellent complexion, voice, strength of the sensory and motor organs and luster. Instead of a society of old and invalid people, it aims at creating a society of youthful vigor-both physical and mental.

Rejuvenation therapy aims at keeping the enzymes in the tissues cells in their normal functioning conditions. These cells are revitalized and their composition is changed. This prevents the process of aging and makes the individual free from any disease in his advanced years. He is able to see as clearly as before and maintain his hearing abilities, as also the glow on his face and the colour of his skin. The sooner the therapy is administered to the individual the better. As the person grows older, this therapy becomes ineffective.

The Rejuvination therapy is administered classically in two ways:

1. Kutipraveshik (Indoor management)
2. Vatatapik (Outdoor management)

For rejuvenation, many drugs are described in Ayurvedic classics, and prescribed by Ayurvedic physicians. The most important ones are Amalaki, Bibhataki, Haritaki, Guduchi and Brahmi. Besides these there are few other Rasayanas which are administered daily increasing the dose with each passing day. The mode of administration, the method of preparation, the dosage, the diet and the precautions to be taken while administering these drugs, vary from drug to drug. Normally, they require the supervision of experts. To obtain the desired effect, the therapy should be followed for a considerable amount of time. The duration of this therapy depends on the age and other physical and psychological conditions of the individual.

There are many pharmaceutical processes to make these drugs palatable. The most common tonic used by Ayurvedic physicians is Chyavanprasha. Ayurvedic physicians consider Chyavanprasha more a food than a medicine. The dosage of this medicine has to be increased gradually. This medicine is absolutely non-toxic.
