Rasayanas are the “wonder” drugs that aid in increasing your natural immunity, enhancing your general wellbeing, improving the functioning of all fundamental organs of the body, and keep the signs of early aging at bay.
The word rasayana is made up of two words: rasa, which means humor of the body, and ayana, meaning source. Rasayana is therefore regarded as the source of all the body humors.
This therapy occupies a prime position in Ayurveda and abides as a distinctive branch that deals with maintaining and ameliorating the body functions, including those of the brain.
Types of Rasayanas
Rasayanas have been categorized in two basic types:
Dravaya Rasayana: This type of Rasayana therapy includes some herb and food types that are indeed beneficial for the optimum functioning of the body as well as the brain.
There are four types of dravaya:
Age-promoting Rasayanas: Some herbs and diets are believed to be of great help in providing stability to life, vitality, and stamina by helping with body and mind fatigue and by augmenting the power of all the five senses. Not only this, these rasayanas provide glow to the skin, sweetness to the voice, and virtually tend to enhance the life span of an individual. Chyavanprash is a popular rasayana, which can be cited as an example, the use of which had restored back youth to Rishi Chyavan.
Brain power enhancing Rasayanas: Regular intake of cow’s milk and ghee (clarified butter) is an effective brain tonic. There are herbs like bramhi, vacha, and shankhpushpi, as well as Ayurveda medicinal formulations like bhrama rasayana which can be taken for long periods of time so as to increase the mental powers of intelligence and memory. Also, these have a stimulating action on the entire central nervous system. Guduchi rasayana is also intellect-promoting and has shown results in promoting powers of grasping, concentration and retention, and also in fighting mental fatigue.
Eyesight promoting Rasayanas: There are some Ayurveda herbal formulations categorized specifically for the benefit of the proper functioning of the eyes (for example, aamalki rasayana). These not only aid in providing clear vision, but also are great of help in problems of decreased eyesight.
Disease combating Rasayanas: In this type, specific rasayanas are given to the patients suffering from some particular disease so as to help eradicate the disease from its roots. For example, bhallataka rasayana is used in diseases of skin and leprosy and pippali rasayana is for respiratory diseases.
Adravya Rasayana: In this type of rasayana therapy, there is no conventional use of medicines. Only the general rules of living and natural regimen of seasons is to be followed. This therapy works in accordance to the science of naturopathy. Man and nature are regarded to be maintaining maximum similarities. Therefore, the laws of nature are inherent in human body. This is the basic idea behind the use of this rasayana therapy.
Let me suggest that for the overall accomplishment of the merits of rasayana therapy, it would be best if both the dravaya and adravya rasayanas are used concurrently.
