A Critical Approach to Evaluating Clinical Efficacy, Adverse Events and Drug Interactions of Herbal Remedies
Phytotherapy research : PTR (2016) · Review
A critical narrative review of published systematic reviews and meta-analyses of herbal remedies. It pools no data of its own.
Both points are doses of a standardised saffron extract (affron) in adults with low mood. A 4-week RCT in 128 adults (PMID 28735826) gave 22 or 28 mg a day: mood improved at 28 mg (POMS total mood disturbance versus placebo, d = -1.10) with no effect at 22 mg. A 12-week RCT in 202 adults with subclinical depressive symptoms (PMID 40414301) confirmed a smaller benefit at 28 mg (DASS-21 depression, d = 0.39). Doses above 28 mg were not compared with lower ones in these trials, so no optimal dose or safety ceiling is plotted. The cited depression meta-analyses pool trials without comparing doses.
The points come from one dose-finding RCT of the Ze 440 extract in 162 women with PMS over three cycles, at 8, 20 or 30 mg a day (PMID 23022391). Total symptom scores improved more at 20 mg than with placebo or 8 mg, and 30 mg did not improve them further than 20 mg, so the curve is flat above 20 mg. All three doses were well tolerated, and no higher dose of this extract was tested. A meta-analysis of 3 trials of characterised extracts (Ze 440, BNO 1095; 520 women) found Vitex users 2.57 times more likely to remit (PMID 31780016). A broader pooled effect was large but rated explorative because of high risk of bias, heterogeneity (I² 91%) and publication bias (PMID 28237870).
AI-estimated from published studies. Interpret as directional guidance.
Saffron has a higher evidence score (7.5/10 vs 7/10) and wins in 3 of 3 categories.
Both Saffron and Vitex score equally (90) for support mood.
No documented interaction was found in the data searched. This does not establish that this exact combination is safe.
Saffron, EPA omega-3, SAMe have real adjunct evidence — but these aren’t a substitute for care, and some interact dangerously.
Ashwagandha, L-theanine, magnesium, saffron — what actually helps stress, and the safety caveats.
The transition years (40s): cycle changes, mood, sleep, brain fog — foundations, vitex, and starting muscle work early.
