Are there any ill effects from swallowing phlegm?
While there is no evidence to suggest that swallowing phlegm is harmful, there are some possible side effects. For example, it can cause nausea or an upset stomach. Additionally, swallowing large amounts of phlegm can make it difficult to breathe, so it is important to clear excess mucus from the lungs to prevent this from happening.
