METHODS: An open label, single dose, clinical design comprising healthy volunteers was employed. The study evaluated PK parameters of the four bioactive constituents RESULTS: After oral administration of 2 WS capsules (200 mg each), the participants reported normal physical, hematological, and biochemical parameters with no abnormalities in safety metrics. For the four bioactives, the exposure parameters range between 0.472 and 4.468 ng/mL (C CONCLUSIONS: The present study elucidated the PK of WS and showed that healthy male and female volunteers may safely consume WS capsules at a dose of 400 mg (2 capsules of 200 mg) without any harmful effects.
