et al, using pure beta-sitosterol which established what a powerful supplement beta-sitosterol complex is for BPH. 7. British Journal of Urology (vol. 78, p. 325-36, 1996) Buck and his colleagues produced a comprehensive review of phytosterols and also explain the 5-alpha-reductase inhibition, lack of side effects and androgen blocking effects. 8. Lancet (vol. 345, p. 1529-1532, 1995) Berges, R. in a randomized, placebo-controlled, double-blind clinical trial of beta-sitosterol in patients with benign prostatic hyperplasia, found that pure beta-sitosterol complex, showed significant improvement in symptoms and urinary flow parameters in the treatment of benign prostatic hyperplasia. 9. Current Therapeutic Research (vol. 55, p. 776-85, 1994) Braeckman et al studied over 500 patients with BPH symptoms and found dramatic improvements in 9 out 10 patients in only 45 days using a high phytosterol content extract of saw palmetto. This is a painstaking and cautious multi-centre open study which proves without doubt the effectiveness and safety of highly concentrated phytosterol extracts in the treatment of BPH. These studies substantiate how 5-alpha-reductase is inhibited so that testosterone cannot be converted to DHT. 10. European Urology, (vol. 26, p. 247-52, 1994) Strauch, G. Compares finasteride drug and saw palmetto in the inhibition of 5-alpha-reductase in healthy male volunteers showing the effectiveness of beta-sitosterol. 11. European Urology (vol. 21, p. 309-24, 1992) Di Silverio and his colleagues showed the effectiveness of very powerful saw palmetto extracts in treating BPH. This was due to the phytosterols exhibiting an anti-estrogenic activity in prostatic tissue of BPH patients. It also showed a powerful inhibition in the conversion of testosterone into dihydrotestosterone by blocking 5-alpha-reductase. 12. Arch Ital Urol Nefrol Androl (vol. 63 p. 341-5, 1991) Carani, C. et al carried out a urological and sexual evaluation of treatment of benign prostatic disease using Pygeum africanum at high doses with positive results. 13. Wien Klin Wochenschr (vol. 23, p. 667, 1990) Barlet, A. had dramatic improvements in a double-blind, placebo controlled, multi-centre study with 263 BPH patients using a Pygeum africanum extract. 14. Med. Sci. Res. (vol. 16, p. 1067-68, 1988) Malini et al., reduced the weight of the dorsolateral prostate using pure beta-sitosterol. 15. Urologe A (vol. 24, p. 49-51, 1985) Vontobel et al., using highly concentrated extract of stinging nettle root, in which beta-sitosterol is the only sufficiently-concentrated active ingredient, effectively treated BPH. 16. British Journal of Clinical Pharmacology (vol. 18, p. 461-2, 1984) Champault et al., dramatically reduced night urination, greatly improved urine flow rate and reduced bladder residual urine when treating BPH using phytosterols, which acted as an anti-androgen to prevent the formation of DHT (dihydrotestosterone) and inhibit 5-alpha-reductase. 17. J Ann Urol ( Paris ) (vol. 18, p. 193-5, 1984) Dufoour, B. showed, in a controlled study, the effectiveness of beta-sitosterol from an extract of African pygeum, on the functional symptoms of prostatic adenoma. 18. Pharmacy (vol. 79, p. 327, 1983) Briley showed that beta-sitosterol inhibited DHT through its anti-androgenic action. 19. Fortschrifte Med. (vol. 101, p. 713-16 (1983) Schmidt et al used a high beta-sitosterol complex from concentrated stinging nettle to improve BPH and also discovered
