  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.

    • 1 Tola is 12 grams.
      1 Pala is 48 grams.
      But taking Narasimha Rasayana in a dose of 48 grams is not possible.
      Consider its dose as 1 teaspoon once or twice a day.

      • If I am not wrong 1 Tola = 12 Masa (11.66 gm)

      • Hello doc,I had consulted a doctor for hair fall and premature grey hair.also for few pre menstrual symptoms…following r d medications prescribed.
        -tiktakam n drakshadi kashayam with manibhadralehyam early morning n evening.
        -abhrabhasmam,kantasinduram n brahmarasayanam after breakfast n after dinner
        -mix of asokarishtam,mridwikarishtam n kumaryasavam ,narasimharasayanam and kanmadasinduram after lunch n before dinner.i took them for 2 months n took break ..pms trouble relieved. I was asked to continue so it’s been 1 month now again…no pms ,less hairfall, but no improvement in grey hair. In fact I see new grey hair….how long would it take to see improvements.

  2. I had premature greying problem and I consulted doc who suggested this along with other medicine. I have a doubt since it is butter based, will I gain weight if I use this.

  3. Sir,

    Can i give this rasayana to my 1.5 year son for weight gain beacause he is underweight and not using any diery items.

  8. hi i am 28 years old. i had premature greying problem. i am under ayurveda treatment for the last 3 moths. i tried manoll syrup some vitamin supplements like bioc bsfo etc. for the last 40 days i have been taking narasimha rasayanam along with liveplus and bhringarajasava. there is no change.. how long it will take to see some change. is there any success cases that you know.

  9. For how long have I to take this to improve my hair growth.

  10. Ashish pandya says:

  13. thanga raj says:

    i m 25 year old. i have gynocomastia. can i use narasima rasayam

  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.

  21. Hello iam 40yrs I have hypo thyroid iam 68kgs 5’6″ and I feel week and hair fall Dr suggested this medicine will I gain weight if ii take 1/2tspoon of this medicine how long I should take
