Hair regrowth :The only FDA-approved product for the treatment of male pattern baldness is minoxidil (Rogaine). One of the main causes of male baldness is the presence of 5-α-reductase, an enzyme which converts testosterone to dihydrotestosterone (DHT). The same phenomena causes Benign Prostate Hyperplasia (BPH) in males and there are a increasing number of clinical studies to show that Saw Palmetto is effective as a 5-α-reductase blocker and in treating the prostatis 9.10,11,12 There is a good chance therefore that it may be also be effective in the treatment of androgenic alopecia, although direct claims of this type cannot be made unless a product is FDA approved. Although no research has been officially conducted there is indirect evidence that Saw Palmetto could be effective in reducing the level of DHT which causes the reduction of the hair follicle and thus hair loss, when applied topically 9. Medicinal and other uses : Seminole indians 3,8 and indigenous people of Florida 2 used the seed for food and it was a survival food of early settlers 2. Flowers used as source of honey 3. Fruit used to aromatise cognac 3. Used as a dietary supplement, primarily as an endocrine and anabolic agent 2. Used in complementary medicine to treat prostate problems, especially hypertrophy 1,2. The National Institute of Health in the US is due to spend $29 million over next 7 years to study the efficacy of saw palmetto on prostatic hyperplasia 5. In Germany the Commission E, a panel of medical and pharmacy experts within the German government, has approved the use of Saw palmetto for early stages of BPH at a dosage of 320 mg/day. Fruit traditionally considered, expectorant, sedative diuretic, anti-inflammatory, also used for coughs, colds, irritated mucous membranes 1,2,3, sore throats, asthma, chronic bronchitis, as a uterine and vaginal tonic 2. Also used for infertility, painful periods amd lactation in women. Folk remedy for cancer 2,3. Palmetto berries have also been attributed with aphrodisiac properties 3. References 1. Grieve, M.
