My daughter has always struggled with enlarged tonsils, especially during colds or flu, the doctors will not do anything to help in the uk and just keep saying no asthma tests can be done until she turns 5. I bought this thinking it probably wouldn’t help much, wanted to give it a go anyway, told by the doctors that it isn’t worth the money and to keep waiting. Well I’ve used this now a good few times when she’s had a cough or cold and the relief she gets is brilliant. No it doesn’t sort her tonsils out (not tonsillitis) but it certainly helps her airways. I have also recently used on my 4.5month old son during a terrible stuffy nose and cold. We make up 1x cup water and 1/2 tsp salt. Impressed.
