Can watermelon frost be swallowed?
Generally, watermelon frost can be swallowed without causing adverse effects on the digestive system. However, individuals with a cold or deficient constitution should use it cautiously. Specific details are as follows:
Watermelon frost is a white crystalline powder made from watermelon and sodium sulfate. Its main functions include reducing swelling and relieving pain, as well as clearing heat and purging fire. It helps alleviate discomforts such as sore throat and mouth or tongue ulcers. It is typically applied topically to the affected area, but some of the powder may dissolve in saliva and enter the digestive tract during swallowing. It usually does not irritate the gastrointestinal tract, nor cause symptoms like nausea or vomiting, or changes in bowel movements such as constipation or diarrhea. Nevertheless, swallowing excessive amounts is not recommended, as it may reduce the amount of medication at the affected site, leading to diminished effectiveness or shorter duration of action.
It is advisable to consult a doctor before using any medication to avoid potential discomfort caused by inappropriate or blind use.
