The green outer layer of the leaves of Aloe vera yields a bitter, yellow exudate which has very different properties from those of the colourless parenchyma. The bitter leaf exudate has traditionally been used as a laxative. However, research has indicated that the active constituents may have harmful effects and can interact with other medicines and herbal remedies. It should not be given to children or to pregnant or breastfeeding women.

Aloes use crassulacean acid metabolism (CAM), a special form of photosynthesis, to help them conserve water.

⦁ Aloes are also able to utilize crassulacean acid metabolism (CAM), which is an adaptation to the photosynthetic pathway in hot climates that involves the formation of malic acid.
⦁ Thick, succulent leaves so in can live in the desert .
⦁ Aloes, like other succulents, have fleshy leaves that hold water to sustain the plant during a drought.
