What the supplied evidence actually contains

No systematic review of aromatherapy for postoperative nausea and vomiting (PONV) was found in the searched records. The closest item is a small randomized trial (n=35 women after cesarean section, three arms) of peppermint aromatherapy vs placebo vs standard antiemetics, reporting nausea on a 6-point scale at baseline, 2, and 5 minutes . Computing group mean severity from the reported distributions:

Caution: the placebo group apparently hit zero nausea for all patients at both timepoints while peppermint scores merely redistributed, which is internally inconsistent with the authors' conclusion of superiority — a red flag for measurement or reporting problems. Other reviews cover insomnia, dementia, and cancer outcomes, not PONV . Bottom line: no PONV-specific systematic review is available in this dataset; the single small trial is low-quality and internally inconsistent, so effectiveness for adult PONV remains unestablished. Missing: pooled RCTs with PONV incidence, rescue antiemetic use, and adequate odor-placebo blinding.

My training data may over-represent positive complementary-medicine trials and under-represent null results, so I weighted internal-consistency red flags heavily.
