Grass Pollen Extract Usage

Two double-blind, placebo-controlled studies found that grass pollen extract can help reduce symptoms of benign prostate enlargement (technically called benign prostatic hyperplasia, or BPH). ¹ One small, double-blind study found evidence that a product containing grass pollen, the pistils (seed-bearing parts) of grass, and royal jelly (a product made by bees) may be helpful for PMS . ² Another small double-blind study found benefit with the same combination for treatment of menopausal symptoms . ³

Grass pollen extract has also shown promise for treating prostatitis . In a six-month, double-blind study of 60 men with non-bacterial prostatitis, use of the grass pollen extract was more effective than placebo in relieving symptoms. ⁴ Grass pollen has additionally been investigated for its usefulness in treating (inflammation or infection of the prostate), prostate cancer, ⁵ and high cholesterol . ⁶ Animal studies also suggest that it may protect the liver from damage by some types of poisons. ⁷ However, the scientific evidence for all of these other proposed uses remains very weak.
