Have your case taken
There are many homeopathic remedies which are known for "lung damage
, " but you can't use homeopathic remedies in a generalized way.
(that is, if you want real benefit). Please consider working with an experienced homeopath who can review your case thoroughly, and find a remedy that applies specifically to you -- all of you, not just your lungs. You are a whole being, and your lungs live in you.
