東革阿里葉萃取
除了我們自 1998 年以來一直不變的東革阿里 1:200 根部萃取物之外，我們也生產東革阿里葉部萃取物，而且我們是全球唯一一家以商業規模生產東革阿里葉部萃取物的公司。
相較於根部，葉子中的 eurycomanone 含量是根部的 20 倍。葉子每毫升含有超過 6 微克的金魚子酮，而根每毫升只有 0.3 微克。

由於葉子中含有大量的 eurycomanone，使用葉子的萃取物往往會刺激睪丸素的合成，因此在短期內會比沒有使用葉子的萃取物更容易令人激動。這可能會導致某些人失眠。
科學研究顯示，劑量較高的 eurycomanone 會透過抑制芳香化酶來增加游離睪酮。芳香化酶是一種可分解循環睾酮並將其轉換成雌激素的酵素。這會造成雙重尷尬，因為芳香化酶不僅會降低生物可用性睾酮，實際上還會將睾酮轉換成抗睾酮。Eurycomanone 可限制這種反應。
劑量夠高時，Eurycomanone 也會扮演磷酸二酯酶抑制劑的角色。請注意，西地那非等藥物也是磷酸二酯酶抑制劑。
