Abstract

BACKGROUND

The present study aimed to evaluate the impacts of lavender and metformin on polycystic ovary syndrome (PCOS) patients.

METHODS

We performed a randomized, double-blind clinical trial including 68 females aged 18 to 45, fulfilling the Rotterdam criteria for PCOS. The patients were randomized to receive lavender (250 mg twice daily) or metformin (500 mg three times a day) for 90 days. The serum progesterone was measured at baseline and after 90 days, one week before their expected menstruation. Moreover, the length of the menstrual cycle was documented.

RESULTS

Our results showed that lavender and metformin treatment notably increased the progesterone levels in PCOS patients (increasing from 0.35 (0.66) and 0.8 (0.69) to 2.5 (6.2) and 2.74 (6.27) ng/mL, respectively, P 3 ng/mL. Lavender and metformin remarkably attenuated the menstrual cycle length in PCOS patients (decreasing from 56.0 (20.0) and 60 (12.0) to 42.0 (5.0) and 50.0 (14.0) days, respectively, P < 0.001). Furthermore, the decreasing effects of lavender on the menstrual cycle length were greater than the metformin group; however, it was not statistically significant (P = 0.06).

CONCLUSION

Lavender effectively increased progesterone levels and regulated the menstrual cycles in PCOS patients, similar to metformin. Therefore, lavender may be a promising candidate for the treatment of PCOS.

How strong is the evidence?

Evidence Hub reads this as a randomized trial, done in people. Its evidence level is 2 of 5 (High · randomized trial). Randomized trials of a reasonable size are the strongest single-study design.
