The korona was the currency in Hungary from 1892 to 1925, so this advertisement comes from then.
The text reads:
A household product you cannot do without is Brázay brand sósborszesz. The price for a large bottle is 2 korona. The price for a small bottle is 1 korona. Instructions for use will be included with each bottle.
 I don't know how to translate sósborszesz. Literally, it means "salty wine alcohol." Hungarian Wikipedia says it is made of water, kitchen salt, fine alcohol, ethyl-acetate, and menthol-crystals, and that the latin name is: Spiritus menthae cum sale. It is called Francovka in Czech and Franzbranntwein in German.
It was used as a remedy for rheumatism and was applied by rubbing it onto the legs to relieve pain and increase blood circulation.
