What symptom indicates absorbed poison?

The correct indication of absorbed poison is characterized by symptoms such as burning, itching, and redness. When a toxin is absorbed through the skin, it can cause localized irritation and inflammation, leading to sensations of burning and itchiness. This occurs because the skin is reacting to the foreign substance that has penetrated its layers. Redness in the affected area is also a common response as blood flow increases to help mitigate the irritant.

Other symptoms like fever and chills, nausea and vomiting, or dizziness and fainting may suggest systemic effects of poisoning or other unrelated medical conditions, but they do not specifically point to absorption through the skin. Burning, itching, and redness, being direct reactions to the contact and absorption of a toxin, provide a clearer indication of poison absorption.
