Is citric acid making a vomiting?

Answer 1

The question is not quite clear. If it is meant to mean "Does citric acid cause vomiting?" The answer would usually be no. Citric acid is the acid found in citrus fruit, such as Oranges and lemons. The acidity would not cause vomiting, as the stomach uses hydrochloric acid to digest food, and is able to cope with quite strong concentrations. The citric acid could cause vomiting if too much was consumed at once, but even water can cause vomiting if taken in very large quantities.
