Interesting heritage: Swedenbitters

Here is something I never saw in Sweden:
SWEDENBITTERS, a bitter herbal of many herbs made in Canada, I think. You buy a bottle with dried herbs and prepare it like this:

Empty contents of package into a wide necked bottle containing 750ml vodka. Shake daily. After 8 days, strain through a clean cheese cloth of fine mesh. Shake the bottle before using.

So, a shot of herb-infused vodka that supposedly helps against colds, digestion problems, liver problems, infections... you name it. I found it interesting that out of the 14 herbs in the recipe, only 3 are wild in Sweden.
