植物界的非那雄胺——鋸棕櫚

鋸棕櫚是生長在北美的自然植物，比如南卡羅萊那、明尼蘇達、密西西比到佛羅里達州一帶。它的成分主要有脂肪（月桂酸，油酸，豆蔻酸，棕櫚酸）,多糖和植物固醇。

最早被美國印第安人用來治療前列腺疾病及尿道感染，後來經過研究發現，它還可以抑制DHT。我們知道雄脫的發生機制就是：體內的睾酮和二型5α-還原酶代謝生成DHT，然後因為毛囊易受DHT攻擊導致萎縮才會脫髮。

所以只要抑制DHT就可以防脫，鋸棕櫚防脫的原理和非那雄胺是一樣的。

因為有非那雄胺的效果，卻沒有非那雄胺的副作用，鋸棕櫚在國外很有名氣。

有實驗將非那雄胺和鋸棕櫚進行了兩年的對比研究：

題目：Comparitive effectiveness of finasteride vs Serenoa repens in male androgenetic alopecia: a two-year study.

內容：The objective of this open label study is to determine the effectiveness of Serenoa repens in treating male androgenetic alopecia (AGA), by comparing its results with finasteride. For this purpose, we enrolled 100 male patients with clinically diagnosed mild to moderate AGA. One group received Serenoa repens 320 mg every day for 24 months, while the other received finasteride 1 mg every day for the same period. In order to assess the efficacy of the treatments, a score index based on the comparison of the global photos taken at the beginning (T0) and at the end (T24) of the treatment, was used. The results showed that only 38% of patients treated with Serenoa repens had an increase in hair growth, while 68% of those treated with finasteride noted an improvement. Moreover finasteride was more effective for more than half of the patients (33 of 50, i.e. 66%), with level II and III alopecia. We can summarize our results by observing that Serenoa repens could lead to an improvement of androgenetic alopecia, while finasteride confirmed its efficacy. We also clinically observed, that finasteride acts in both the front area and the vertex, while Serenoa repens prevalently in the vertex. Obviously other studies will be necessary to clarify the mechanisms that cause the different responses of these two treatments.

主要內容我總結為：實驗尋找了100名脂溢性脫髮患者，一組每天服用320mg的鋸棕櫚，一組每天服用1mg的非那雄胺，分別服用2年。38%患者服用鋸棕櫚頭髮生長變快，68%患者服用非那雄胺情況有所改善。通過結果發現，非那雄胺對患者前額和頭頂有效，鋸棕櫚主要對患者頭頂有效。

通過研究可以發現，鋸棕櫚對雄脫的恢復是有效的，但有效率極低.....10個人中不足4人用了會有效，最終效果也不及非那雄胺好，它的好處就是副作用極小了。

市面上的鋸棕櫚產品只是保健品，不能取代非那雄胺的治療作用，順手搜索了一下價格，也不便宜，可以拿來治療脫髮，但沒必要，如果真的擔心非那副作用，試試也無妨，但是對自己是否有用就要做好準備了~
