CONTEXT: Phyllanthus amarus Schumach. and Thonn. (Euphorbiaceae) is traditionally known to improve general liver health. However, its effect on hangover is unknown.

OBJECTIVE: This study evaluated PHYLLPRO™, a standardized ethanol extract of P. amarus leaves for protection against oxidative stress and recovery from hangover symptoms.

MATERIAL AND METHODS: Ten days daily oral supplementation of 750 mg/day followed by intoxication was evaluated in a randomized placebo-controlled (containing only excipient), crossover study in 15 subjects (21-50 years old), for oxidative stress, liver damage, alleviating hangover symptoms (Hangover Severity Score: HSS) and mood improvement (Profile-of-Mood-Scores: POMS).

RESULTS: PHYLLPRO™ was able to remove blood alcohol in the active group while the placebo group still had 0.05% at 12 h post-intoxication (p < 0.0001). For HSS, the active group showed reduced hangover symptoms while there were higher levels of nausea, headache, anorexia, tremulousness, diarrhoea and dizziness in the placebo group (p < 0.05) at hour 10 post-intoxication. Increased fatigue at hour 2 and tension (p > 0.05) from baseline to hour 22 was reported in the placebo group using POMS. Significant anti-inflammatory group effect favouring the active group, by the upregulation of cytokines IL-8 (p = 0.0014) and IL-10 (p = 0.0492) and immunomodulatory effects via IL-12p70 (p = 0.0304) were observed. The incidence of adverse events was similar between groups indicating the safety of PHYLLPRO™.

DISCUSSION AND CONCLUSION: Preliminary findings of PHYLLPRO™ in managing hangover, inflammation and liver functions following intoxication, is demonstrated. Future studies on PHYLLPRO™ in protecting against oxidative stress and hangover in larger populations is warranted.
