I grew up in America, but my family is Korean. Which means they had secret techniques for dealing with common issues not known to most stateside.
As an adolescent, whenever I had indigestion from eating too quickly (which happened often), my mother would squeeze my wrist and poke my thumb with a needle. Dark blood would ooze out and within minutes the stomachache would go elsewhere. This actually worked. I don't know how or why it does, but every Korean kid knows this from their childhood.
For those more averse to needles and blood, there is Gas Whal Myung Su. It is a carbonated beverage only sold in pharmacies in Korea, and is useful for treating many discomforts of the tummy. Here, you can probably find it in most Korean supermarkets.
Menthol notes dominate the nose, with peppermint and winter fresh toothpaste immediately coming to mind. It has a very fresh aroma with an herbal backbone. A creamy texture overwhelms the palate, leaving a refreshing mouth-feel behind. The cooling sensation continues down the esophagus and there is an immediate sense of comfort in the stomach. Gas Whal Myung Su should be stored and served at room temperature.
Whoever thought no one would ever write up a tasting for a Korean medicine... just got served (a tasting note!).
