Sorry folks - Emily H especially but I don't know how magnesium helps in asthma. On one of my jaunts this morning I did look it up in a book in a charity shop(!) - exciting jaunts I have I know. The information was scattered through the book which was actually aimed at taking supplements. If I think it would help I would prefer to have it in food form if poss with my allergies.
Which will be the next question - Which foods are rich in magnesium.
Hope all are as well as possible Thanks SandiX
