The fruits of ''bhallataka'' – undamaged, undiseased, mature in taste, size and potency, looking like ripe ''jamboo'' fruits should be collected in the month of ''jyeshtha'' and ''ashadha'' and be stored within the granary of barley or black gram. After four months, in the month of ''Agrahayana'' or ''Pausha'' they should be taken out for use by one who has made his body fit through the intake of cold, unctuous and sweet substances. At first ten fruits of ''bhallataka'' should be crushed and boiled in ten times of water, when 1/8 extract remains, it should be filtered and taken mixed with milk after smearing the inner part of the mouth with ghee. Gradually increasing the dose by one fruit per day it should be led to thirty which is the maximum dose. In this way the total number of fruits taken comes to one thousand. When the drug is digested, one should take ''shali'' and ''shashtika'' rice with milk added with ghee. After the treatment is over, the patient should live on milk diet for the period double to that of treatment. By this one attains stable life span of one hundred years without senility. Other impacts of the treatment are as mentioned before. [13]

Here are the verses-
 +
 
 +
The fruits of ''bhallataka'' are irritant, inflaming and are like fire but they assume nectar like properties if used as prescribed. Their use in the above ten forms is described which should be prescribed considering the disease, constitution, and suitability. There is no disorder of ''kapha'' and obstructive condition which is not ameliorated by ''bhallataka'' quickly. Moreover, it promotes intellect and ''agni''.
 +
 
 +
In early days, the old great sages like Chyavana etc, who desiring vital strength, attained immeasurable life span by using these beneficial ''rasayana'' formulations. After attaining longevity they performed as desired, spiritual penance, celibacy and self- medications and ascended to the heaven. Hence those who desire longevity, vital strength and happiness should use the ''rasayana'' methodically and carefully. [17-22]

A ''vaidya'' has to care for the patients as if they were his children or family members. A ''vaidya'', by practicing with compassion towards the ailing, earns much more than wealth. Therefore, a ''vaidya'' should not consider treatment as a business. This advice of [[Charak Samhita]] holds true even today. Those who serve patients with this attitude, get such benefits from the society, which no other profession can get, and unmatched as compared to wealth.

Clinical trials on Rasayana have shown that Ashwagandha (Withania somnifera), Guduchi (Tinospora cordifolia) and Pippali (Piper longum) are effective in the treatment of allergic disorders such as eczema, urticaria, allergic rhinitis, and bronchial asthma; autoimmune disorders such as rheumatoid arthritis or cancer or pulmonary tuberculosis. It provide better and faster relief, prevent recurrences and also improve quality of life.Furthermore, Medhya Rasayana drugs are found effective in stress-induced conditions such as anxiety and insomnia or neurodegenerative conditions such as Parkinson's disease, Alzheimer's disease, and senile dementia. The findings of all these studies indicate that Rasayana has a definite role to play in the maintenance and preservation of health, and appropriate use of Rasayana can help to bring down the prevalence of many diseases, ultimately reducing health-care burden.<ref>Goyal M.
