A) ARG + WPH intervention increased plasma serotonin levels (expressed as AUC [pm × min]) in 27 healthy volunteers over time in comparison to NV control (WPH + ARG: 350 ± 218, NV set to 0). Statistical significance between treatments was calculated by One Way ANOVA (p > 0.05). Group mean after WPH+ARG intervention was significantly higher than that after NV control treatment as identified by Mann–Whitney Rank Sum test (p < 0.05). Values are shown as mean ± SEM. Plasma serotonin concentrations of the NV control group ranged from 0.40 to 42 pg mL–1. B) Influence of NV control, WPH, ARG, and WPH + ARG intervention on plasma serotonin levels. Statistical significances were tested by One Way ANOVA and t‐test on plasma concentrations over time as well as on AUC values (p > 0.05). Plasma serotonin concentrations are depicted as mean ± SEM.
