More specifically, the present invention relates to a composition for stimulating cell growth, especially for stimulating epidermal cells and hepatic cells, which contains aloesin as an active ingredient. Aloesin is a component of Aloe vera, for which an effect for blocking ultraviolet ray from skin and an activity as mushroom tyrosinase inhibitor have been disclosed in the prior art. However, accordint to the present invention, it has now been identified that aloesin has the novel pharmacological use as a cell growth stimulating agent which has never been disclosed in the prior art.
