What is it
Marjoram (Origanum majorana) is a culinary herb in the mint family used traditionally for digestive complaints and as a tea. As a supplement it appears as leaf extract, tea, or essential oil. Limited clinical research has looked mainly at hormonal/metabolic markers in women with PCOS, with most other uses resting on traditional use and lab data.

hormonal and insulin markers in PCOS
Biomarker supportA small randomized trial of marjoram tea in women with PCOS reported improved insulin sensitivity and a reduction in adrenal androgen (DHEA-S) levels compared with placebo. This is a single small study measuring hormonal/metabolic biomarkers, not clinical outcomes such as ovulation, fertility, or symptom resolution. The finding needs replication.
Bottom line: One small trial shows favorable hormonal/insulin biomarker shifts in PCOS, but clinical benefit is unproven.
digestive comfort
Mechanism onlyMarjoram is traditionally used as a carminative for indigestion and bloating, and lab studies show antispasmodic and antioxidant activity in its constituents. There are essentially no controlled human trials confirming a digestive benefit, so this use is supported by tradition and mechanism only.
Bottom line: Traditional digestive use is plausible but lacks controlled human evidence.
