Surprising
A sesame oil dab lowered phlebitis severity more than a common herbal alternative in 108 patients on an IV heart drug — but the trial was open-label, so patients and nurses knew who got what.
This is a single, unblinded trial in a hospital setting, so while the effect was large and statistically significant, the result needs replication before it applies to everyday use — treat it as an intriguing signal, not settled science.
Hospital patients receiving an IV heart medication (amiodarone) were randomly assigned to have sesame oil, Nigella sativa oil, or nothing applied around the IV site. Over the 74-hour monitoring period, the sesame oil group had the mildest vein inflammation — only 25% developed any phlebitis compared to 80.6% in the control group — but because neither patients nor staff knew which oil was used, the lack of blinding could have influenced how inflammation was scored.
Where this fits in the evidence
This is among the first studies we've indexed on Sesame for Reduced Phlebitis Severity — treat it as an early signal until more research accumulates.
