What is one substance that can be used to delay the absorption of poison from the digestive tract?

Activated charcoal is effective in delaying the absorption of poison from the digestive tract due to its high surface area and porous nature. When ingested, activated charcoal can bind to various toxins and chemicals present in the stomach and intestines. This binding process prevents the poison from being absorbed into the bloodstream, effectively reducing its harmful effects. The mechanism relies on adsorption, where the charcoal particles trap the poison molecules on their surface, allowing the bound substances to be excreted from the body rather than entering circulation.

This makes activated charcoal a common treatment in cases of certain types of poisoning or overdose, as it can significantly mitigate the impact of the toxic substance when administered soon after ingestion. It is important to note that activated charcoal is most effective if given within a certain time frame after the poison is swallowed, highlighting the importance of quick medical intervention in such situations.

In contrast, the other substances listed, such as aspirin, caffeine, and vitamin C, do not have the same properties or effects in the context of poison absorption, making them ineffective for this specific purpose.
