Which symptom is characteristic of Salicylate poisoning?

Tinnitus is a hallmark symptom of salicylate poisoning, which commonly occurs due to the ingestion of high doses of aspirin or other salicylate-containing medications. This symptom is the result of the drug's effects on the auditory system and can manifest as ringing, buzzing, or other auditory disturbances.

Salicylates can cause metabolic disturbances, particularly metabolic acidosis, and can affect various body systems, which may lead to other symptoms like confusion, hyperventilation, or gastrointestinal issues, but tinnitus specifically arises from the interaction of salicylates with the inner ear or central nervous system.

While diarrhea, constipation, and excessive salivation can occur with other medical conditions or types of poisoning, they are not specifically associated with salicylate exposure, making tinnitus the distinctive symptom in this context.
