Some of the ingredients in Holland & Barrett's Aloe Vera Colon Cleanse are known to have laxative and gut stimulating properties. The Aloe Vera Colon Cleanse tablets are, therefore, able to act as a colon cleanse.
Aloe Vera Cleanse, manufactured by Holland & Barrett, contains aloe vera gel as its active ingredient. It also contains a number of other herbs, including buckthorn and dandelion root. Aloe vera latex is a strong laxative, but Aloe Vera Cleanse only contains aloe vera gel. Buckthorn acts to relieve constipation, and dandelion root is a laxative.
The Food and Drug Administration banned the use of aloe vera latex as a laxative in 2002 due to lack of information about its safety. It is possible that oral consumption of aloe vera latex can cause cancer and kidney damage.
