text: for anyone with asthma, what christmas trees are best for you? i was told silver tip, but not sure.?   i've had asthma (and allergies) all of my life. i've had all kinds of trees.  you have to remember that people have different types of asthma and different triggers for their asthma. christmas trees don't bother me, but i can walk into a house and tell if you have a cat or a dog. lol.  growing up we did real trees. now i do artificial because i think throwing a tree away is silly and wasteful.
