Yin and Yang water sounds very zen and magical, but the master who told me this idea was actually my mom. Called 음양탕 (Eum-yang-tang) in Korean, Yin Yang water is made with one simple ingredient: water itself. It’s rather quite well-known in oriental medicine; by combining the natures of the positive and the negative, this water perks up your system and stimulates circulation. Drinking lots of water is good for you, right? So I figured, might as well boost its function by turning it into Yin Yang water!
