Put the candy, herbs and corn into a large preserving jar (approx. 2 l capacity) with a well-closing lid (alternatively 2 milk glass bottles of 1 l capacity each). Close the jar tightly and shake well.
Place the herb mixture in a warm, light place for 14 days, shake 1-2 times a day. After 14 days, strain through a gauze cloth. Pour the Swedish Bitters into well sealed bottles and store in the dark.
Always drink Schwedenbitter diluted: mix 1 teaspoon with 1 cup of warm water or herbal tea.
