Asthma, pregnancy, obesity

During Asthma and obesity, it is best to avoid this medicine, especially in a dose higher than a teaspoon a day. Consult your doctor for its usage during pregnancy.

Use of Shatavari kashaya

Some versions of Ashtanga Hrudayam mentions Piarvyaha kashaya in place of Varaya Kashaya.
Pivari is a synonym of Shatavari – Asparagus racemosus.
So, some manufacturers use Shatavari kashaya in place of Triphala decoction.
If Shatavari is used, then the potency of the product will be slightly cooler compared to that of Triphala decoction. However, this would not change the overall benefits of the product by a great extent.

Please consult your doctor before taking this medicine.

  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.

    • 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.

    • Hi Dr,
      Thank you for the above link. However one of my friend suggested to take narashima rasayanam to gain weight.
      So is it gonna help me?

  3. 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.

  4. 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!

  12. Hi, if this medicine is advised in a low dose for a shorter period of time, it will not cause any weight gain. Include exercise as part of your routine and continue with your doctor’s advice.

    • as it is having nutritive and rejuvinative property it can be used, along with you can also try mahabringaraja taila application and massage for scalp. it can be consumed quarter table spoon with water before food once daily.

  15. I understand from the web that this is good for hair growth. I am 50 and my hair is thinning.You have also mentioned that diabetics and BP patients should not take this so what do you recommend for hair growth.

  16. hi,
    no, all those medications can be used, since they will do nutrition supplement to your body. hence they will treat you from root cause of your hair fall. use these along with application of tailam.

  17. hi…,
    if at all your digestion capacity is good then no problem. there will not be any side effects. you could practice some yoga, pranayama and dhyana also for sound mind and sleep.
