Silica gel desiccant is insoluble in water and any solvent, non-toxic, odorless, chemically stable, and does not react with any substance except strong alkali and hydrofluoric acid. At the same time, silica gel is the only FDA-certified desiccant, which can be used for direct contact with drugs and food. If you eat it by mistake, don't worry, because it is not absorbed by the stomach, but can be excreted through feces, which is not toxic to the human body. You don't need special treatment after taking it by mistake, unless you have special reactions such as dizziness and vomiting, you generally don't need to see a doctor.
The raw material of lime desiccant is quicklime (calcium oxide), which expands when it meets water and generates a lot of heat. Eating by mistake will burn the skin and stomach, and it will be gradually eliminated because of frequent explosion injuries. If you eat by mistake, you should drink water or milk immediately, but you should control the amount of drinking, and take it per kilogram of body weight 10 ml, with the total amount not exceeding 200 ml. Because overdose may cause vomiting, severe cases need to be sent to hospital for treatment.
