Grass Pollen Extract
Principal Proposed Uses
Other Proposed Uses
Like the more famous saw palmetto, extracts of grass pollen are used to treat prostate enlargement. The grass mixture utilized to make this preparation consists of 92% rye, 5% timothy, and 3% corn. 1 Grass pollen has also been investigated for its potential to treat prostatitis , prostate cancer, symptoms of menopause and PMS, and for reducing cholesterol. Related grass pollen extracts are used for allergy shots. The grass pollen extracts described here have their allergenic component removed, and so can't possibly work to treat hay fever (see Safety Issues below). Grass pollen is also an entirely different product than bee pollen .
Grass pollen extract tablets for prostate disease are available in pharmacies and health food stores or can be ordered from a number of sources on the Internet.
Therapeutic Dosages The recommended dosage for grass pollen extract tablets is between 80 and 120 milligrams (mg) per day. 2
Therapeutic Uses 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). 3,4 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 . 22 Another small double-blind study found benefit with the same combination for treatment of menopausal symptoms . 23Grass 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. 24 Grass pollen has additionally been investigated for its usefulness in treating (inflammation or infection of the prostate), prostate cancer, 8–10 and high cholesterol . 11 Animal studies also suggest that it may protect the liver from damage by some types of poisons. 12 However, the scientific evidence for all of these other proposed uses remains very weak.
