What is the purpose of Activated Charcoal in medical treatment?

Activated charcoal is primarily used in medical treatment for its ability to absorb toxins present in the gastrointestinal tract, making option B the correct choice. When a person ingests a toxic substance, activated charcoal can bind to the poison, preventing its absorption into the bloodstream. This is particularly effective for certain types of poisoning, allowing the body to excrete the toxins without them causing further harm.

The use of activated charcoal is most effective when administered shortly after the ingestion of a toxin, as it needs to interact with the substance before it is absorbed into the system. Its mechanism involves a large surface area that enables it to trap various chemicals and poisons, reducing their availability for absorption in the intestines and facilitating their elimination from the body.

In contrast, the other options do not accurately reflect the primary use of activated charcoal. It is not indicated for alleviating allergic reactions since such reactions typically require antihistamines or other specific interventions. It does not promote digestion or administer nutrients as its role is not related to digestion or providing essential nutrients to the body. Therefore, understanding the specific function of activated charcoal highlights its importance in managing certain poisoning situations effectively.
