I practice most of these and I love EOs. Unfortunately the EOs that are good for lung health are very bad for seizures so I have to avoid most of them, even rosemary.
I stick mostly to the citrus EOs.
That is difficult indeed. Citrus EOs have a lot to offer; what about other mints like spearmint?
Also I was remembering how it helps with lung health to open the chest via various kinds of exercises, putting shoulders back, head up, and sort of putting the chest out, and breathing, doing repetitions. There are hatha yoga poses that help with that and no doubt other ones. These help my lungs, as well as regulated deep breathing.
