Generally speaking, the effects and functions of wild perilla leaves mainly include relieving superficies and dispersing cold, regulating qi and harmonizing the stomach, resolving phlegm and relieving cough, detoxifying and reducing swelling, and regulating qi to stabilize pregnancy. The specific analysis is as follows:
1. Relieve Superficial Cold Syndrome
Wild perilla leaves are warm in nature and pungent in taste; they can disperse cold pathogens, alleviating symptoms caused by colds such as chills, fever, headache, nasal congestion, and clear nasal discharge. When cold pathogens invade the body, consuming wild perilla leaves can help expel external cold pathogens, relieve discomfort, and promote recovery.
2. Regulate Qi and Harmonize the Stomach
Wild perilla leaves can promote gastrointestinal motility, regulate the qi of the spleen and stomach, and improve gastrointestinal discomfort such as abdominal distension, nausea, vomiting, and loss of appetite. When qi stagnation occurs in the spleen and stomach, consuming wild perilla leaves can help regulate qi circulation, enhance digestive function, and maintain gastrointestinal comfort.
3. Resolve Phlegm and Relieve Cough
Wild perilla leaves have the function of resolving phlegm, helping to dilute respiratory tract mucus, promoting the expulsion of phlegm, and simultaneously relieving cough symptoms. When coughing with excessive phlegm and thin sputum is caused by cold pathogens invading the lungs, consuming wild perilla leaves can reduce cough frequency and improve breathing difficulties.
4. Detoxify and Reduce Swelling
Externally applied, wild perilla leaves can alleviate skin problems such as sores, swellings, rashes, and itching; when taken internally, they can assist in relieving abdominal pain and diarrhea caused by poisoning from fish or crab. When experiencing related discomforts, appropriate use of wild perilla leaves can help reduce swelling and itching and alleviate toxic reactions.
5. Regulate Qi and Stabilize Pregnancy
Wild perilla leaves can regulate qi circulation, relieving nausea, vomiting, chest and abdominal distension, and other pregnancy-related reactions caused by qi stagnation during pregnancy. If related discomfort occurs during pregnancy, consumption under professional guidance can alleviate symptoms and support a healthy pregnancy.
Wild perilla leaves are warm in nature; individuals with yin deficiency and excessive internal heat should not consume them in excess to avoid aggravating internal heat. Those with allergic constitutions should use them cautiously to avoid allergic reactions such as rashes and itching. As an adjuvant dietary therapy, they cannot replace medical treatment for diseases; timely medical attention is necessary for severe symptoms. Special populations, such as pregnant women, should consult a qualified physician before use to ensure safety.
