The Rasayanas are prepared from natural herbs. An aqueous extract (decoction) is prepared by using combination of herbs by boiling the herbs in a steam boiler by adding eight times purified water and it is reduced to l/8th of the water added initially. Then it is filtered. In this decoction sugar (Jaggery) is added at a temperature of 100 degree C and the temperature is brought down to room temperature. At this temperature the herbal powders, which have to be added are slowly added by continuous stirring and mixing till it attains the prescribed semisolid consistency. This may not be very much agreeable to the consumer sometimes. Children generally do not like to consume such preparations because of the taste, colour and odour. Hence by adding certain ingredients it is made palatable and with a natural aroma to suit the tastes of all age group of people, especially children.
