Why is it called hair of the dog?

Answered by Randy McIntyre

The term “hair of the dog” is often used colloquially to refer to having another drink to cure a hangover. But have you ever wondered why it is called “hair of the dog”? Well, let me take you back to the origins of this peculiar expression.

Originally, the phrase “hair of the dog” had nothing to do with alcohol or hangovers. It actually originated from an ancient belief and practice of treating a rabid dog bite. In those times, it was believed that the best remedy for a dog bite was to take some hair from the dog that bit you and place it into the wound. This practice was thought to have healing properties and prevent the onset of rabies.

As the concept of “like cures like” became more widely accepted over time, the phrase “hair of the dog” began to be used metaphorically. It was eventually applied to the idea that consuming a small amount of the substance that caused your ailment could alleviate the symptoms or cure you. In the context of alcohol, it meant that having another drink could help alleviate the unpleasant symptoms of a hangover.

Now, let’s dive deeper into the reasoning behind this peculiar belief. When we consume alcohol, our body metabolizes it into acetaldehyde, a toxic substance that contributes to hangover symptoms. Hangovers are often accompanied by symptoms like headache, nausea, fatigue, and sensitivity to light and sound. The hair of the dog theory suggests that by consuming more alcohol, you can temporarily alleviate these symptoms by providing your body with a small amount of the same substance it is trying to process and eliminate.

However, it is important to note that the idea of using alcohol to cure a hangover is not backed by scientific evidence. In fact, it can be counterproductive and potentially harmful. While having another drink might provide temporary relief, it can ultimately prolong the hangover and potentially lead to a cycle of dependency or alcohol abuse.

So, while the phrase “hair of the dog” has a fascinating origin and history, it is crucial to approach it with caution and prioritize responsible drinking habits. It is always best to give your body time to recover and opt for healthier methods to alleviate hangover symptoms, such as staying hydrated, getting plenty of rest, and consuming nutrient-rich foods.

The expression “hair of the dog” originated from an ancient belief and practice of treating dog bites. Over time, it evolved to metaphorically refer to the idea of consuming a small amount of the substance that caused your ailment to cure or alleviate the symptoms. However, relying on alcohol to cure a hangover is not scientifically supported and can have negative consequences. It is important to approach alcohol consumption responsibly and prioritize healthier methods of dealing with hangover symptoms.
