Synopsis

Source of validity: Traditional
Rating (out of 5): 2

Camellia sinensis, the tea plant (green or black tea), has a longstanding traditional use in various cultures as a remedy for hangover symptoms. In China, Japan, and other East Asian cultures, tea is often consumed following alcohol intake, purportedly to alleviate headaches, nausea, and fatigue associated with hangovers. The rationale is largely based on folk wisdom: tea is thought to help rehydrate the body, stimulate the mind, and speed recovery. Some of these effects may be due to the caffeine content, which can increase alertness, and the presence of polyphenols and antioxidants, which have general health benefits. However, clinical evidence directly supporting the use of Camellia sinensis for hangover relief is limited. A few small studies suggest that antioxidants in green tea may help reduce oxidative stress caused by alcohol metabolism, but these findings are preliminary and not specific to hangover symptoms. Overall, the use of tea for hangovers is primarily justified by tradition, with limited scientific support. The overall evidence rating for its effectiveness in treating or supporting hangover recovery is low (2/5).
