Vaseline (petroleum jelly) is considered safe for human consumption in small amounts, but it is intended for topical use only and not as food. It has been purified multiple times to remove impurities and is generally non-toxic if accidentally ingested. However, it has a very unpleasant taste and texture, making eating it difficult and not recommended. Eating large amounts could cause gastrointestinal discomfort such as abdominal pain, diarrhea, or throat irritation. It is best to use Vaseline only as directed on the skin and avoid eating it deliberately.
In summary:
- Vaseline is safe to swallow in small accidental amounts.
- It is not meant to be eaten intentionally or regularly.
- Large ingestion can cause digestive issues.
- Use it topically for skin protection and healing.
