Pollen extract versus placebo for hot flashes and quality of life
Randomized, placebo-controlled, parallel-group study in 64 menopausal women. After 12 weeks of daily use, 65% of women taking the pollen extract had fewer hot flashes, compared with 38% on placebo (p < 0.006). Hormone levels didn't differ between the groups, and the authors reported improved quality of life.
