“I’ve heard that if you get Asian glow that if you drink pepto bismol before you drink, you won’t turn red, but I don’t get Asian glow so I guess I would never find out first hand. Unfortunately.”
“Asian glow” describes when a person of Asian descent consumes alcohol and experiences flushing of the face, neck, and chest. This is often considered unattractive and embarrassing. This phenomenon stems from a single mutation in the aldehyde dehydrogenase gene, which ultimately prevents the breakdown of alcohol. Because acetaldehyde builds up in the body, creating the symptoms characteristic of Asian glow, the condition is commonly thought of as an allergic reaction. I have definitely heard of drinking Pepto Bismol to quell Asian glow because it contains common digestive enzymes that prevent other conditions, but recommended dosages vary from a capful to an entire bottle. This advice is a modern folk remedy.
