Hi! Aloe Ferox (cape or bitter aloes) and Aloe Vera are both in the Aloes family of plants, but the Cape Aloes contains MORE Emodin, which is the constituent, that causes the bowels to go into peristalic action.

Anyhow, you could use Aloe Vera, but you must realize that it probably won't work as a laxative as well as Cape/Bitter Aloes. You'll NEED to call Moutain Rose Herbs and ask for the herbalist-on-staff, and ask him/her, are you selling Aloe Ferox or Aloe Vera?
"THANKS" for your post!
