In addition to what I posted on the group wall in response.
I found this during my most recent study, I have yet to try it but I trust the source as genuine:
Activity can be modulated in the brain hemispheres by breathing through the opposite nostril. If you want to increase left-brain function close the right nostril, or to increase right-brain function close the left nostril. Specifically for the lungs you could try Alpha Lipoic, L-carnitine, Essential Fatty Acids, N-Acetyl-Cysteine (NAC). Use the leaves, flowers and seeds of borage and you will find it to be a Godsend for normalizing and calming. Make teas of borage, chamomile, elderflower, lemon balm, marshmallow, mullein and peppermint. Eat bioflavinoid rich foods...spinach, berries, elderberries, red peppers...think max color.
