Surprising
Crocin from gardenia slashed TNF-α by nearly 2 standard deviations in a meta-analysis — but the same review found it did nothing for two other inflammation markers.
This is the first meta-analysis on crocin and inflammation, so the finding is promising but still preliminary — the large effect on TNF-α needs replication before you can count on it.
A meta-analysis of 13 clinical trials found that crocin, a compound from gardenia, strongly reduced the inflammatory marker TNF-α. However, the same analysis showed no significant effect on erythrocyte sedimentation rate or malondialdehyde, meaning the anti-inflammatory benefit may be narrower than the headline number suggests.
Where this fits in the evidence
This is among the first studies we've indexed on Gardenia for Reduced Tumor Necrosis Factor Alpha — treat it as an early signal until more research accumulates.
