I love this bottle. There was a small Rexall Drug Store in my hometown that I used to enjoy going to. I like the colors of the label and the bottle design. This bottle has lump alum in it. It can stop the bleeding of minor cuts or nicks, much like a styptic stick. The stick is used for spot treatment, and the alum is used for larger areas. The bottle also states that it can be used as an astringent, gargle, or occasional douche. Ammonium Alum.
