not so great for internal [SEP] i am doing a cleansing that calls for castor oil ingesting it and of course i wanted the purest this one looked by the hundreds of oddly similar star reviews about eyelashes like it was it the best so i got it to replace another brand but this one was not better for interal use it kind of ripped right through me in a way not even similar to my other brand i realize now that it says external use only and have read posts from numerous people trying to figure out if that statement is just a precaution to satisfy the fda but after my experience i am going to speculate that there may be more to it than that it might truly need to be used external only i think i will go back to my cheap one to finish my cleanse and gladly in the meantime i may try it on my eyelashes but not inside my eyes
