History of Genuine Haarlem Oil

Haarlem Oil a natural treasure discovered 450 years ago


THE DUTCH ALCHEMYThe History of Haarlem Oil dates back to the 18th century and its history is connected to the Dutch alchemy.


Claas Tilly is renown elaborating his Medicarnentum Gratia Probatum during the year 1696. The composition of the remedy attributed to Claas Tilly, renowned for its effectiveness in treating kidney and bladder ailments, owed a great deal of its success to Professor Hermann Boerhave. It was Professor Boerhave who contributed the crucial detail in the production process, further enhancing its efficacy. Hermann Boerhave, Professor at the University of Medecin, Leyde, was one of the most famous doctors at this time. As Professor Hermann Boerhave participated in the benefits of this medicine that rapidly found its popularity, the ethics of his profession prevented him from associating his name with an object from an industrial ownership.


The Genuine Haarlem Oil is produced in a factory equipped with sophisticated, intricate and expensive equipment. The ingredients follow a process that take several days, in which the particular chemical preparation and difficult analysis has permitted the Tilly Family to preserve the secret of the production during 200 years. Claas Tilly passed away during the year 1734, after being successful in the affair. His sons, Koning Tilly, followed by G. Koning Tilly succeeded him.


Unfortunately, the business has ended after Claas Tilly’s death. It was probably due to the competition and the numerous imitations that hindered the quality of the product and its reputation. During this era, the reputation of Genuine Haarlem Oil had spread throughout Europe and the other parts of the world. Thus, many families at Haarlem tried to copy this elixir. The only resemblance was having the same name but never the secret of the formula made by Claas Tilly and Hermann Boerhave in 1696 originally.



Thus, it becomes evident that the novel properties acquired by sulfur in this unique combination substantiate Haarlem Oil as an indispensable source of bioavailable sulfur in nutrition.


Studies show the exceptional bioavailibility of sulfur contained in Haarlem Oil and another study shows the SOD action (super oxydismutase).


The understanding of the specific molecular structure’s ability to penetrate the secret remains within the realm of scientific knowledge. During the 1990s, Mr. Charles Stirnweiss, a pharmacist, and Mr. Kirsch, a professor at the Faculty of Metz. Spearheaded a collaborative research effort with the research laboratories of Elf Atochem. This undertaking involved comprehensive investigations and studies. It is up to this generation and the next generation to continue the research and not forget that the alchemists are still working on this elixir. Our knowledge increases; we have the everyday knowledge of biochemistry on the central role of sulfur; but remember that Genuine Haarlem Oil will never change: it is a precious heritage.


Throughout the 18th century, the foundations of modern chemistry were established, and organic chemistry gained prominence during the 19th century. However, it wasn’t until the late 20th century that modern biochemistry reached a level of maturity that allowed for a comprehensive understanding of the intricate mechanisms underlying life.


Evidence has also shown the importance of nutrition and the hygiene of life in maintaining health. Our understanding leads us to recognize that the role of science. In the healthcare field extends beyond the mere discovery of remedies and treatment of illnesses. It also encompasses the provision of essential information for maintaining good health, delaying the aging process, and protecting against environmental aggressors. Often, illnesses take place long before we look after our health. Today, if needed and wanted, everyone can improve or conserve their fundamental health.
