Tar water

Tar-water was a medieval medicine consisting of pine tar and water. As it was foul-tasting, it slowly dropped in popularity, but was revived in the Victorian era. It is used both as a tonic and as a substitute to get rid of "strong spirits". Both these uses were originally advocated by the philosopher George Berkeley, who lauded it in his tract Siris: A Chain of Philosophical Reflections and Inquiries, Concerning the Virtues of Tar Water. It was regarded by medical experts to be quackery.

The use of tar water is mentioned in the second chapter of Charles Dickens's Great Expectations. Young Pip and his brother-in-law, Joe, were often force fed it by Mrs. Joe, Pip's elder sister, whether they were ill or not, as a sort of cruel punishment.

The physician Cadwallader Colden extolled the virtues of pine resin steeped in water. This concoction also was called "tar water".

George Berkeley suggested that tar from pine or fir be stirred for three or four minutes with an equal quantity of water and the mixture allowed to stand for 48 hours. At this time, the separated water is drawn off to be drunk, at the rate of one half-pint night and morning "on an empty stomach". Fresh water is added to the unused portion and again stirred to provide more of the preparation, until the mixture becomes too weak.

Explorer Henry Ellis praises tar water as "the only powerful and prevailing medicine" against scurvy during his 1746 voyage to Hudson's Bay (although his editor, James Lind, notes that "a want of greens and herbage" was the chief cause of the outbreak).

Fleuriot the lieutenant, who suffers from consumption in second degree, is mentioned to have been advised to take tar water in aid of his battle against the ailment, by Sarrazin the general in Memoirs of Vidocq by Eugène François Vidocq:
