The
Cochrane Collaboration , a group ofevidence-based medicine (EBM) reviewers, reviewed the use of "Nei guan" (Acupoint P6) for nausea and vomiting, and found it to be effective for reducing post-operative nausea, but not vomiting.

EBM reviewer Bandolier said that "P6 acupressure in two studies showed 52% of patients with control having a success, compared with 75% with P6 acupressure".
