In postmenopausal women undergoing cervical screening, sea buckthorn oil suppositories used for 2 weeks improved vaginal tissue integrity and imaging quality compared to no treatment—performing similarly to prescription estrogen ointment. The improvement made the screening procedure easier to perform and more satisfactory, though this study focused on procedural outcomes, not treating cervical conditions themselves.

Researchers gave 368 postmenopausal women either sea buckthorn oil suppositories, estrogen ointment, or no treatment for 2 weeks before cervical colposcopy, then compared how well the screening procedure went across the three groups.
