What does Aloe Vera leaf pulp compose?


It is widely claimed  that Aloe Vera composes of more than 200 chemicals that could be benefial to the human body. I sought to find out if this is true and I found an article in a scientific journal called Mollecules, Volume 13(8) published in 2008. The author; Josias H. Hamman gives a summary of the chemical Constitution of Aloe Vera leaf pulp below. He mentions that the active constitutes of Aloe Vera can differ depending on the origin of the leaf but are on average as below.  This strengthens the concept of Aloe Vera’s drinking Aloe Vera Gel for health and beauty benefits.
