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 0.05) 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.

Background. Physta is a proprietary product containing a freeze-dried water extract of Eurycoma longifolia (tongkat ali), which is traditionally used as an energy enhancer and aphrodisiac. We aim to evaluate a 300 mg combination of Physta and Polygonum minus, an antioxidant, with regard to sexual performance and well-being in men. Methods. Men that aged 40-65 years were screened for this 12-week randomized, double-blind, placebo-controlled, parallel-group study. Outcome measures included validated questionnaires that aimed to evaluate erectile function, satisfaction with intervention, sexual intercourse performance, erectile hardness, mood, and overall quality of life. Results. 12 subjects in the active group and 14 in the placebo group completed the study. Significant improvements were noted in scores for the Sexual Intercourse Attempt diary, Erection Hardness Scale, Sexual Health Inventory of Men, and Aging Male Symptom scale (P < 0.05 for all). Three adverse events were reported in the active group and four in the placebo group, none of which were attributed to study product. Laboratory evaluations, including liver and kidney function testing, showed no clinically significant abnormality. Conclusion. Supplementation for twelve weeks with Polygonum minus and the proprietary Eurycoma longifolia extract, Physta, was well tolerated and more effective than placebo in enhancing sexual performance in healthy volunteers.
