Beta Sitosterol is the most abundant phytosterol in the diet. It is also widely distributed in the plant kingdom and found in such botanicals as Serenoa repens (saw palmetto), Curcurbita pepo (pumpkin seed) and Pygeum africanum. These three botanicals are used in the herbal management of benign prostatic hypertrophy (BPH). There is some belief that Beta Sitosterol plays some role in the possible benefits of these herbs in BPH. Beta Sitosterol itself is used as a medicine in Europe for BPH. It is a popular natural alternative used for years by men in Europe. It improves urological symptoms and flow measures.
The structure of Beta Sitosterol is similar to that of cholesterol. It has also cholesterol-lowering activity. A study published by the Lancet showed that men with BPH, who took Beta Sitosterol, had significant improvements with urinary problems. It seems to reduce the cholesterol level in the prostate. It might also work through its anti-inflammatory activity. Regular intake of high levels of Beta Sitosterol might also reduce blood cholesterol levels. The cholesterol lowering property of Beta Sitosterol is the result of a lower absorption of cholesterol.
