... that taking St John's Wort can weaken the effects of the blood thinnerphenprocoumon? Source: "Die Wirkung von Phenprocoumon kann durch gleichzeitige Gabe von Johanniskraut-Zubereitungen abgeschwächt werden. The effect of phenprocoumon can be weakened by concomitant use of St John's Wort preparations." ([1])
Overall: Article is new enough, long enough and looks well sourced. Hook is cited and interesting. No copyvio detected (although a lot of the sources are in German). Looks good to go! BuySomeApples (talk) 04:43, 27 August 2021 (UTC)[reply]
