I found this website when searching for recipes to use Japanese quince, drschar.com
It is not cranky and is careful about saying you should always consult a conventional health professional first. It makes a really fascinating read for anyone interested in natural health.
And by the way I discovered that quinces have anti inflammatory properties!
Thanks Buffafly, I'm just having a look - I see they do gluten free products, which will interest a friend of mine... Big website, just trying to find natural health things now

Sorry, not got the hang of cut and paste on tablet! I saw the site you mentioned, bit naughty I think, them, not you!
No, my fault, posted link now
Agree about avoidance if you can, unfortunately I have inflamed lungs and it is impossible for me to avoid all causes so a food that would generally reduce inflammation in the body might help. Also, I seem to recall that there is a theory that AF may be associated with inflammation in some way? seems logical.....
I think I have had asthma since childhood but it was not identified as such until middle age unfortunately as I suffered a lot of ill health. Much better now as I use a regular inhaler and take an antihistamine as well. I am affected by so many things, pollen, dogs, mould, house dust - only alternative is to live in a bubble!
My AF seems to be brought on quite often by a virus. I have noticed a few obvious triggers but I try not to obsess about it as so far I have been quite lucky compared to some.
I know some members are very interested in healthy nutrition and alternative therapies which is why I posted the link
