Yes it is used. There are different versions. I've noticed all of them revolve around spices such as cloves and such. These were spices popular in that day and age.
Many individuals, including me, have used this just by diffusing it in the air or opening the lid and waving it under your nose. It is believed to "rid" the air of bad germs. Germs that make us sick. It actually smells very nice. You'll find in all versions the predominant scent is that of cloves! An antiseptic amongst many other things.
Or that has been my experience.
