George Frederick Laidlaw, The Treatment of Hay Fever by rosin-weed…
“ My experience can be paralleled by many hay fever patients that as long as I remained among the pines, I was in perfect health but on going down into the valley, one breath of fragrant wind blowing over the fields would cause instant itching and swelling of eyes and nose and all the previous hygienic life up at the lake was no protection against the disorder. I have seen the hereditary form develop in three children of one family while they were at the seashore, bathing daily in salt water and living a care-free, active, out-door life, never taking tea, coffee or alcohol and not much meat. ”
