I read that chronic sinusitis can be cause by a fungal infection caused by allergy to moulds. Does the Neti work the same way if the infection is fungal instead of bacterial?
Yes. Jala Neti works on removing anything which is up your nose and in your sinus cavities which shouldn’t be there. Pathogens of many kinds enter the nose all day. It is the job of the cilia (little hairs) to filter out larger particles for blowing out; it is the job of the sticky mucous linings to trap smaller particles for blowing out; and finally it is the job of the sinuses’ runny fluids to flush out the tiniest germs which might get that far in.
