Can mouthwash be drunk?
I've heard that using mouthwash can help relieve bad breath. I was wondering, is it safe to swallow mouthwash?

Mouthwash is generally not recommended for ingestion, as it is an external product primarily intended for oral hygiene and care. Its ingredients and formulation are designed to remain in the mouth for a short period and exert their effects locally.
Mouthwash may contain ingredients such as essential oils, flavoring agents, alcohol, surfactants, and strontium chloride. Ingesting these components directly may irritate the gastrointestinal tract and potentially cause adverse reactions such as poisoning, dizziness, or other harmful effects on health.
Although small amounts of residual mouthwash may be swallowed with saliva after rinsing, the quantity involved in such cases is usually minimal and generally does not cause noticeable harm to the body. However, if a large quantity of mouthwash is intentionally or accidentally ingested, prompt measures should be taken, such as drinking plenty of water or consuming plain milk, to help alleviate irritation and discomfort in the gastrointestinal tract. Medical attention may also be necessary in some cases.
If any adverse symptoms occur, seek medical attention promptly. For children, mouthwash should be stored out of their reach to prevent accidental ingestion.
