Paracelsos (1493-1541 AD), the great alchemist of the Renaissance and father of modern medicine, in 1538 formulated the "elixir of longevity". He called it "universal therapy" and promised that anyone who received it "would harmonize the most important functions of its internal organs and benefit its whole body" in order to achieve "prolonging its lifetime".

Unfortunately, the original recipe was lost or stolen and discovered 250 years later, in an unpublished handwriting. Swedish doctors Dr. Urban Hjarne and Dr. Claus Samst, whose many elements of life are unfortunately not known, worked on this recipe. They were both holders of this secret longevity. The first died at age 83, three times married to 26 children, and the second died at the age of 104 after an accident with his horse. In a manuscript of Dr. Samst explains in 46 points that this "elixir of longevity" stimulates, revitalizes, protects and heals every illness.

Schweden Bitter, pronounced "queven bitter" and means "Swedish bitter", has been widely used in Central Europe, and even today its efficacy against many diseases causes scientific research of the secret of this herbal mixture.

Schweden Bitter is a carefully balanced mixture of 16 herbs, prepared in pure alcohol without any sweetener. This produces a bitter but pleasant, aromatic drink. It is suitable not only for oral use but also extremely effective when applied externally
