Silica gel is non-toxic, and non-reactive and stable with ordinary usage. It will react with hydrogen fluoride, fluorine, oxygen difluoride, chlorine trifluoride, strong acids, strong bases, and oxidizers. [22] Silica gel is irritating to the respiratory tract and may cause irritation of the digestive tract.
Canisters are commonly filled with silica gel and other molecular sieves as desiccants in drug containers to keep contents dry Silica gel in a sachet or porous packet. A desiccant is a hygroscopic substance that is used to induce or sustain a state of dryness (desiccation) in its vicinity; it is the opposite of a humectant.

Gel packs are often made of non-toxic materials that will remain a slow-flowing gel, and therefore will not spill easily or cause contamination if the container breaks. Gel packs may be made by adding hydroxyethyl cellulose, [2] sodium polyacrylate, superabsorbent polymer or vinyl-coated silica gel.
Good question. I came here wondering if I could use silica gel in a reaction instead of sodium silicate. The article (now) sounds like it doesn't clearly know: "Silica gel is a granular, vitreous, highly porous form of silica made synthetically from sodium silicate." "Synthesized" would be much clearer than "made synthetically."
Catalyst poisoning is the partial or total deactivation of a catalyst by a chemical compound. Poisoning refers specifically to chemical deactivation, rather than other mechanisms of catalyst degradation such as thermal decomposition or physical damage.
