  1. Dear Sir,

    I have a Sanskrit-Hindi translated Ashtanga Hrudaya. In that, under the
    Narasimha Rasayan section, it is written that, it has to be taken in 1 PAL

    Sir, please let me know how much is 1 PAL in grams.

    Also, i would like to know that these units of measurement like PAL,
    TOLA etc are they all same or are they different in Ashtanga Hrudaya, Bhaishyajratnavali, Rasatarangini and other texts.

  14. Sir,
    I am Taking 1 teaspoon everyday of narasimha rasayan for hair growth .
    But i hav a doubt if i gain fat .
    Is so pls Tell me …
    THank you

  15. hi sir,
    since i have a problem of hair fall , my doctor suggested me to take narasimha rasayanam. iam over weight also i.e iam 23 years old and my weight is 65. so my query is that if i take this will i gain more weight..?

    • If it is in a lesser dose of half a teaspoon a day, it would not contribute to weight gain.
      If you are above 5.4 feet, then 65 kg is not a big weight issue. Your Body Mass Index would fall within 25, indicating good height and weight ratio.
      Exercise for at least half an hour a day, to counter the weight gain effect of Narasimha Rasayana.

  16. i am having heavy hair fall can i use it or can you suggest me some other?

  17. my doctor asked me to take one spoon after food morning and night. Is it fine to take this medicine after food.

  18. Hello,

    I am suffering from Hypo Thyroid and have had terrible hairfall in the last 3 months.. Will Narasimha rasayanam help in my case?

  19. I am 24 yrs old and about 60 kgs. I have hair fall problem. Can i use this product ? I am concerned as it is butter based, will it increase my belly size ?? (I am prone to a belly by hereditary)

  20. Hello Doctor,

    Can you tell me…..
    1) the difference between taking N.Rasayanam after breakfast, and before breakfast on empty stomach? Does it work differently if taken on empty stomach?
    2) Can this medicine be used daily lifelong?
    3) Can this medicine be used alongwith Ajaswagandhadi leham / Ajamamsa Rasayanam?

    Thank you!

    • 1. Not much difference. But it is better to take it before food.
      2. Better to limit its usage for 2 – 3 months of time only.
      3. Yes, but this, with the other, will contribute to weight gain. You will have to exercise and do diet control to counter this effect.
