Betel leaves are a mild stimulant that the locals like to chew on for a couple of minutes. Unfortunately, the leaves cause their mouths to water, which in turn is mixed with the red dye of the substance. People then spit this out onto the floor causing red stains along the street. The first impression when you see this ubiquitous marking on the floor may be blood. But, it’s not.
When you’re in Myanmar, you’ll see people chewing this and will become familiar with the red stains that line the streets. Vendors sell large green leaves containing the nut with spices and occasionally tobacco. Try it yourself if you dare.
