Haarlem oil (Dutch: haarlemmerolie), also called medicamentum gratia probatum, is a dietary supplement. The potion is a mixture of sulfur,herbs and terebinth oil. It is produced in Haarlem, Netherlands.
It was invented in 1696 by Claes Tilly and was marketed as a cure for many ailments.
The word haarlemmerolie (with a lowercase 'h') is now used in Dutch to indicate a fix for all problems. For example: "lowering taxes will be like haarlemmerolie for the economy". This is also used sarcastically.
