Pygeum contributes to the maintaining of the health of man's prostate. It is mainly used to help the treatment of prostate adenoma BPH, a condition that affects men in the early 40s, but increases with age: 30% of 50-year-olds; 50% of 60-year-olds; and almost 80% of men over 70. BPH include changes in the prostate: increased size and increased density of the tissue.
These changes cause the symptoms of urinary urgency of a small amount, decreased secretion of the prostate, reduced bladder emptying. Incomplete bladder emptying increases risk of infection, inflammation, and edema.
Pygeum africanum is an evergreen tree that grows in some areas of Africa. The bark, which is used, is not collected until the wood is not fully grown. It contains three groups of active ingredients: phytosterols (such as beta-sitosterol), pentacyclic triterpenoids (including ursolic and oleic acids) and ferulic esters of long-chain fatty alcohols (including ferulic esters docosanol and tetracosanoic).
Bark oil contains many active ingredients, waxes, fatty acids, and other lesser-known components. The main biological activity of pygeum is assigned to the compound "phytosterol", known as beta-sitosterol. Phyto (plant) sterols are structurally similar, but with less efficient absorption than cholesterol. The biological effect of phytosterols is similar to that of hormones.
Pygeum helps to maintain blood sugar levels and supports the function of the immune system.
