What is Tonic Water?

Originally, tonic water was used for the delivery of quinine, which is a drug that fights malaria. Quinine comes from South American cinchona tree bark. During the early 1800’s, a British military officer stationed in India invented the gin and tonic, after realizing that the alcohol made the medicine more tolerable.

Summer is a time for warm day foods and clear liquor beverages. Tonic water is effervescent and has a bitter taste, which makes it a perfect partner with gin for summer alcoholic drinks.

But wait – excessive drinking of alcohol is bad for your health, so does that mean that tonic water is also bad for you? Basically, it just depends on the type of tonic water, its nutritional content, its ingredients and how much you drink.
