does anyone know where and how the saying "hair of the dog" originated?

Answer 1

Meaning:

* If someone has a hair of the dog, they have an alcoholic drink as a way of getting rid of a hangover, the unpleasant effects of having drunk too much alcohol the night before. It is commonly used as a way of excusing having a drink early on in the day.


The Bloody Mary, invented during the Roaring Twenties, is still touted as the ideal morning-after pick-me-up. Another evil-sounding but reputedly effective concoction popularly believed to relieve the symptoms of a hangover is called "Black Velvet" and consists of equal parts champagne and flat Guinness. Hemingway, it is said, relied on a morning-after tonic of tomato juice and beer.

Another is
The saying now refers to having a drink of the same that made you drunk to cure a hangover. So the idea is whatever makes you ill makes you better. In the mid 1500's it was believed that if you were bitten by a mad dog then taking a hair from that dog and placing it across the wound would accelerate the healing process.
