While alcohol has been found to have stress relieving benefits (duh) and can function as a sleep aid (double duh), overall, studies find that moderate drinkers tend to live longer. However, here are some specific ailments that may or may not be prevented or cured for those drink or two a day type folks:
Arthritis I remember a few years ago I told my mom about my incurable love of gin. My mom then told me that her aunt used to soak raisins in gin to help soothe arthritis pains. I didn't believe her at all, but rather I just assumed that was a free pass to gin it up. However, according to Nass, this arthritis cure is actually pretty common.
Type 2 Diabetes A collection of 15 studies concluded that drinkers were found to be 30% less likely to develop type 2 diabetes.
Malaria Quinine, which is extracted from cinchona bark, is found in tonic syrup, as well as a few different liqueurs and fortified wines like Cocchi Americano. Quinine was used as a cure for malaria back in colonial times.
Blood Clots Since alcohol is a blood thinner and has been shown to increase HDL or good cholesterol levels, it can also help prevent strokes, heart attacks, and other issues from blood clots.
Memory Disorders Another study found that the ethanol in alcohol can prevent Alzheimer's and dementia by helping the brain resist wear. However, long-term excessive drinking can lead to alcohol related dementia. During a series of problem solving tests, male drinkers were found to perform better than non-drinkers.
Frostbite? My favorite alleged spirituous cure is that of brandy's. It's a common myth that St. Bernards would help save injured skiers in the Alps with small barrels of brandy strapped to their collars meant to keep them warm. While it isn't true because the blood thinning properties of alcohol would make you freeze faster, hopefully it's only a matter of time until dog-delivered barrel-aged cocktails become a thing.
