Full title: Effectiveness a herbal medicine (Sipjeondaebo-tang) on adults with chronic fatigue syndrome: A randomized, double-blind, placebo-controlled trial Open access, https://www.sciencedirect.com/science/article/pii/S2213422020303000
So if I read this correctly the questionnaire used as the primary outcome measure, the Checklist of individual strength, which appears to be a fatigue questionnaire, showed no significant between group difference, but other fatigue questionnaires including the Chalder one did show a significant difference. I think the key finding from that has nothing to do with the specific medicine being tested, but the inconsistency between fatigue scales, making them all useless as measures of anything.
I sure would want to know all the herb's chemical properties and any toxicities before ingesting it in a clinical trial.
