Does perilla (Perilla frutescens) expel roundworms? Is it edible?

Perilla does not have anthelmintic properties and generally is not used for expelling roundworms. It can be consumed as a food seasoning or to alleviate symptoms of mild colds caused by wind-cold invasion or food poisoning from fish or crab. However, individuals allergic to perilla or those with symptoms of yin deficiency and excessive internal heat should avoid consuming it. If any abnormal reactions occur, prompt medical attention is recommended. Detailed explanations are as follows:

Perilla contains volatile oils and can be used in cooking to enhance flavor. For example, adding perilla when preparing freshwater or seafood dishes helps eliminate fishy odors and improve aroma. When experiencing mild symptoms of a cold due to wind-cold, such as chills and slight nasal congestion, or gastrointestinal discomfort caused by eating fish or crab, drinking perilla-infused water may help alleviate symptoms. In these situations, perilla can be used as a supplementary food for symptom relief.

Perilla is warm in nature. People with yin deficiency and excessive internal heat may experience worsened symptoms like oral ulcers or swollen gums after consuming it. Individuals allergic to components in perilla may develop allergic reactions such as skin itching, rashes, or even respiratory tract swelling after consumption. Those with these conditions must avoid perilla to prevent harm to their health.

Before consuming perilla, ensure you understand your body constitution and health status. Do not use perilla as a substitute for professional medical treatment. Seek timely medical care if severe discomfort occurs.
