Original Swiss Herb Candy is tasty and pleasantly refreshing. The recipe for the original, world-famous Swiss herb candy has changed almost nothing since 1940. It is kept completely secret, but it has only been revealed that its power comes from 13 Swiss herbs: horehound, pimpernel, speedwell, marshmallow, lion's foot, elderflower, mallow, mint, sage, yarrow, primrose, plantain and thyme.
