What did short studies miss?
The 2026 trial reported no adverse events or clinically significant changes in the safety markers it measured over 12 weeks. That is reassuring within this small study, but does not resolve long-term safety. NIH describes loose stools and more frequent bowel movements with Coleus extract and notes the lack of longer-term trials. 1 2
