In Aloe vera, which part is primarily associated with a laxative effect?

• A. Latex
• B. Leaf gel
• C. Root
• D. Flower

Answer: (A)

The key idea is that Aloe vera has two different plant parts with distinct actions: the latex and the leaf gel. The latex is where the strong laxative effect comes from because it contains anthraquinone glycosides (such as aloin). These compounds irritate the intestinal mucosa and stimulate peristalsis, while also drawing water into the bowel, which together produce laxation. The leaf gel, in contrast, is rich in demulcent polysaccharides and acts mainly as a soothing, moistening, gentle topical or internal demulcent rather than a stimulant laxative. The root and flower are not the sources traditionally associated with Aloe’s laxative action. So, the part primarily linked to a laxative effect is the latex.
