Given the possible risks and unsubstantiated benefits, people should not consume Aloe vera . People who choose to consume it should at least look for products made with a charcoal filtration process to decolorize and remove anthraquinones, and monitored to ensure than aloin levels are low (., 1 part per million or less). Some solid or semi-solid products have much higher levels of aloin. However, low levels of aloin do not guarantee safety, since it is not known for sure exactly which components of Aloe vera triggered cancers in rats.
Semi-crystalline cellulose polymers react at pyrolysis temperatures (350–600 °C) in a few seconds; this transformation has been shown to occur via a solid-to-liquid-to-vapor transition, with the liquid (called intermediate liquid cellulose or molten cellulose ) existing for only a fraction of a second.  Glycosidic bond cleavage produces short cellulose chains of two-to-seven monomers comprising the melt. Vapor bubbling of intermediate liquid cellulose produces aerosols , which consist of short chain anhydro-oligomers derived from the melt.
