Pennywort Juice (Nam Bai Bua Bok)

Earthy, green, and subtly bitter, pennywort juice is beloved across Thailand as a true “cooling” drink. Known locally as “น้ำใบบัวบก,” it’s made from fresh pennywort leaves blended with water, then lightly sweetened to balance the grassy notes. The result is a garden-fresh taste that feels instantly quenching in the heat. Street vendors typically sell it in clear cups over ice, and many markets offer take-home bottles. If you prefer a cleaner profile, request it with minimal syrup or ask for ice to dilute. Pennywort pairs beautifully with grilled pork skewers, seafood, or anything spicy. Those sensitive to bitterness will still enjoy it when served chilled and slightly sweet. It’s a nourishing, everyday option that’s widely available, budget-friendly, and a real local favorite for hot afternoons.
