History of
Haarlem Oil for Horses
History of Haarlem Oil Horses | The Genuine Haarlem Oil is produced in a factory equipped with sophisticated, intricate and expensive equipment. The ingredients follow a process that takes several days, in which the particular chemical preparation and difficult analysis has permitted the Tilly Family to preserve the secret of the production for 200 years.

It is therefore left to put forward an irrefutable way, that the new properties acquired by the sulfur in the combination, could confirm that Haarlem Oil is an essential source of bioavailable sulfur in the alimentation.
