Bee pollen products reportedly alleviate the symptoms of menopause without hormonal changes. One study even showed that pollen had some anti-hormonal effects. The present study was a randomized trial of women over 18 without residual but with severe menopausal symptoms on therapy of either tamoxifen or aromatase inhibitors. They were given either a mixture of pollen and honey (sunflower) or pure honey and did not know which they were receiving. The honey was thought to be a placebo. They were treated for 14 days and then given a 14 day break, after which they were switched to the other treatment.
