Weight loss:
One person has experienced weight loss with this product. Upon taking this for cough for 2 months, he had experienced 5 kg weight loss.
The reason for this is, Haritaki – acts as a mild laxative and has shoshana – drying properties. This helps to balance Kapha dosha and lowers the body fat. Hence, Agastya Haritaki makes a perfect remedy if a person is obese and is having respiratory symptoms.

With inhaler

I suffer from asthma and take steroid inhalers. But my mother always gives me Agastya Rasayana whenever I get cold or cough. I find this medicine very effective. Do you think I could take a prolonged course of this and slowly come off the steroid inhalers? Has anyone done this before in your experience?

Yes, this medicine can be taken for a longer period only under the supervision of an Ayurvedic practitioner. Agastya rasayana, if taken for longer duration, acts as a respiratory tonic and it reduces the severity and frequency of asthma attacks.

And in the question, there is a query regarding stoppage of steroid inhalers after the prolonged intake of Agastya Rasayana. This medicine alone might not enable you for that. But it is very effective in reducing the symptoms and intensity of asthma attacks. So, with a good Ayurvedic treatment protocol, you can certainly reduce the frequency of steroid inhalers over a period of 1 – 2 months. Please do consult an Ayurveda doctor in person.


A research study has been conducted on Agastya haritaki to evaluate its therapeutic actions.

      Waiting for your reply….

  4. J’ai commencé un traitement de agastya rasayan car je suis en Inde actuellement mais lorsque je vais rentrer en France où me procurer ce produit ? Merci de me donner une adresse.

  5. Dear Dr.,

    I am a big fan of yours. I read your blog and site and am awestuck at the amount of kindness you have shown to mankind and the world at large…Thanks for all your efforts.

    I have a question – will regular daily intake of Agasthya Rasayanam increase Migraine attacks?


  6. It can be given, but in a very low dose. You will need to consult an Ayurveda doctor directly.

    • If your doctor in Kerala had prescribed this to the kid, then it can be given with little honey.

  7. hello Dr
    i have been taking Agasthya Rasayana ,Past 30 days.It is really amazing for get relief from continuous cough and cold.My doubt is specially based on food intake, during this medicine.My doctor advised – not to take meat in this time.I don’t know,only restriction for oily food or meat?.But i am an non-veg lover.Can you please suggest me with your opinion.

    • The probable reason you were told to avoid meat was, because meat is heavy-to-digest, this may cause impaired digestive fire, causing increase of Kapha and worsening of cough and related symptoms.
      If you just love meat, consider adding a bit of spices to it, while cooking – like black pepper powder, cumin powder etc. It will help in supporting your digestive strength, without affecting your cough in a negative way.
      Do not indulge too much in meat. Have it in limited quantities only.

  8. Sir,
    Recently there was mild mucosal thickening in my frontal Sinus(Ct Scan) which led to slight headache and my Ayurvedic doctor prescribed Agastya Haritaki Lehya(Daily 1 spoon) and other ayurvedic tablets and nose drops. After 5 days of using the medicines, my headache got cured. And now I am getting slight cough with Mucus(yellowish and green). I can feel that the thick green mucus is coming from my wind pipe(trachea). Earlier i did not have this problem. Should I continue using Agastya Haritaki Lehya? Please elaborate your answer. Thanks in advance.

    • Hi, the slight cough and mucus might just be Kapha getting eliminated out of your body. Use Agastya Rasayana for around 6 weeks before stopping it. Drink lukewarm water, avoid ice cream and cold drinks during this period.

  9. Sir which company is good. I had Agastya rasayanam from kottakkal, arya vadya sala, but it had Honey and ghee in equal proportion. Is it safe to take?

    I am sceptical as you have mentioned earlier that honey and ghee should never be taken in equal proportion.

    Also I say they use the same proportion of honey and ghee in Brahma Rasayan and Chawanprash also.

    Many Thank

  10. Agastya rasayana is same as agastya haritaki rasayana.
    Taking Chyawanprash along with Agatya rasayana would be a bit stronger combination and needs direct approval of an Ayurveda doctor.

  11. Hi, Dr
    I have cough from last 3 months with mucus (green & white)
    what do you think using daily 2 spoon twice is enough or i
    can take for 3 times daily.

    Thanks in advance for your reply

    • English medicines can be taken along with this medicine.
      Whenever taking Ayurvedic and English medicines together, it is healthy to maintain a gap of half an hour between the two sets of medicines. Take English medicine first, wait for 30 minutes, then Ayurvedic.

  12. Hi Doctor,
    I searched for agasthyarasayam and they said they have both kottakal and oushadi agasthyarasayanam.Which one is good?

  13. What is the difference between Agastya Rasayana and Dashamoola Haritaki Avaleham?
    Once an ayurvedic doctor had prescribed the latter(Dashamoola) for anemia. It gave relief for cold n cough too. Is this because some of the ingredients are common?

  14. I have been asked by my doctor to take agastya rasayanam and pravala bhasmam in the night to increase the thickness of my hair . Will it help??

  15. Hi, once after sinusitis is completely treated, you can have narasimha rasayana. taking it now, does not look a good idea.

  17. Sir,
    I have been taking agastya Leham, dashamula Leham, vyagharadi Leham with swarnamukthadi tablets for 2 months for sinusitis. How long should i continue this for complete cure?

  18. Hello doctor , I get cough very often and it stays for 2 to 3 months. the first two three weeks it’s a wet cough with high kapha and after that it’s feeri cough and continues for another 2.5 months.

    my doctor has been prescribing Agasthya Rasayanam and Vyaghradhi Leham alternatively. I have been consuming them for the last 2 years but could not identify which one works better.

    My doctor told me it’s a kind of Allergic cough. Which medicine will be better for me.

    I have tried Vyoshadi vatakam, balajeerakadhi kvadham and dashamoola kaduthrayadi kvadham also as per doctors advice.

    Please help..

  19. Hello Dr, you say it has drying properties and that one can loose weight with this rasayanam, so is it still ok for someone with asthma, high vata, dry yellow nasal crust, and already really (too) skinny?

  20. Hi Doc
    Does taking Nutritional medicines at the time of diseased condition aggravates the disease.
    ie after cleansing process only Nutritional medicines has to be given
    Best Regards

    • In Ayurveda, when there is a disease, only if the patient is very weak even to tolerate the medicines, only then nutritional medicines are given. Till the patient recovers from the disease, primary target of medicine is to cure the disease without harming the health of the patient.

      If the patient’s digestion strength is low and if we are supplying nutrition rich medicines, they may further lower the digestion strength in some cases. So, target the disease first, while keeping patient’s strength to tolerate the medicines / treatment in mind.
