castor oil中文是蓖麻油，不是大麻油

首先，castor　oil中文是蓖麻油，不是大麻油。蓖麻和大麻雖然是同屬植物，但是法律上大麻是禁品，所以你說用大麻油，好比說病人應該吸大麻，同樣是使用違禁產品，是違法的。即使醫學上有根據，版主也有根據刪除提倡違法活動的帖子。

其次，"according to the American Cancer Society, "available scientific evidence does not support claims that castor oil on the skin cures cancer or any other disease."[27]" http://en.wikipedia.org/wiki/Castor_oil
