Swedish bitters

Swedish bitters, also called Swedish tincture, is a bitter and a traditional herbal tonic, the use of which dates back to the 15th century.
Origins.
Swedish bitters is said to have been formulated in a similar way to ancient bitters by Paracelsus and rediscovered by 18th century Swedish medics Dr. Klaus Samst and Dr. Urban Hjärne, though this appears to be mistaking the latter for his son, Kristian Henrik Hjärne, who himself invented a bitter.
In modern times, Swedish bitters have been popularized by Maria Treben, an Austrian herbalist. The tonic is claimed to cure a large number of ailments, and to aid digestion. These claims are presented with little in the way of scientific evidence to support them, though empirical evidence provides for a very large database of positive results.
