My mother kept a bottle of terpin hydrate in the medicine cabinet for years "just in case." Mom considered it to be somethiog of a magic bullet because the family doctor of my childhood and an aunt who worked in a drug store were both fans of the stuff.
We were spoon-fed Tennessee moonshine with a little bit of honey and lemon when we were kids. Best thing ever for breathing issues. In fact, Dad used to go to the mountains to get a gallon at a time for a local doctor that made his own cough medicine.
