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.
