With only a whiff.........

Dropped into a local chemist today and while waiting I blipped this.
There are two cabinets full of oils, potions and tinctures (now there's a word you don't hear too often), beakers, instruments and other wonders from early last century.

I'm guessing there are a few out there who could do with a whiff and I'm also guessing that whatever was in the pouch is now on the list of restricted drugs.
