I personally use it for skin conditions and aching muscles myself. Healing wounds and fading scars and on bruises and as a general tonic for my skin on a daily basis if I have enough supplies of homemade tincture and floral water. I am a pretty healthy person thankfully so don't ever seem to get respiratory problems thus but am getting older as we all are so anything good for maturing skin will naturally win my vote hahaha
I really feel like I still have more to learn about this plants power though, it's one of my absolute top 5 for health and longevity.
