Is there any asanas for Rhinitis.
Not that I’ve heard of, specifically. A whole yoga practice can help you see where the inflammation is coming from, and a bit of inversion (lying on your bed, scooch your head and neck off of it so you can look straight out at the wall opposite you) can move stuff – and hopefully it moves to where you can excavate it rather than to where it is more difficult to excavate.
Let’s see what more experienced folks say . . .
Try the kriya (cleansing technique) called neti. Get yourself a neti pot and neti salt and learn how to clean your nostrils the yoga way.
