This randomized and placebo-controlled study examined the effects of Phyllanthus amarus for the management of hangover symptoms. 15 subjects have been enrolled and received for 10 days a placebo or 750 mg/day of PHYLLPRO®, A P. amarus leaf extract, before alcohol intoxication.

The supplementation accelerated alcohol removal from blood in comparison to placebo at 12-hour post-intoxication (p < 0.0001). The Hangover Severity Score showed lower hangover symptoms in the active group, whereas nausea, headache, anorexia, tremulousness, diarrhea and dizziness were noted in the placebo group (p < 0.05). Higher fatigue and tension were also noted in the placebo group. The assessment of cytokines showed an anti-inflammatory effect of P. amarus.

Therfeore, this small pilot study suggests that a P. amarus leaf extract can reduce hangover symptoms, partly by preventing alcohol-induced inflamamation.
