This is basically a hormone extract from ground up pig adrenal glands, which sit right on top of the kidneys, and produce nifty things like cortisol, and adrenaline.
It was commonly used to treat lung disorders such as bronchitis, and asthma. Presumably it would function similarly to a modern day inhaler for someone with asthma.
I’m not sure on the date, but I’m guessing this is post 1970.
