A lot of the medical advice has probably been superceded and some of the chemicals they advocate using in the house have probably been judged unsafe and or improved on but basically it's quite a good introduction to hayfever and what it means to be allergic.

Also asks some interesting questions like: why didn't hayfever appear until the late 19th/Early 20th Century? They postulate that perhaps cars are involved somehow but they're unsure how. I'm sure myself that it possibly has some roots in the digging up of land to put roadways on them and the fact that smaller, small-pollen bearing plants took over the hedgerows, along with the fact that the traffic churns up dust when it's dry.
