Perilla seeds, or perilla seeds, have the effect of lowering qi and resolving phlegm, relieving cough and calming asthma (stopping cough and calming wheezing), and can relieve cough and asthma symptoms experienced by patients with lung nodules, but cannot play a better role for those with severe symptoms. Perilla seed is pungent in flavor, warm in nature, and enters the lung and large intestine meridians to treat cough and asthma, intestinal dryness and constipation, and phlegm congestion. It is not suitable for people with lung deficiency cough and asthma, spleen deficiency loose stool (thin and unformed feces), otherwise it will cause adverse effects such as aggravation of cough and loose stool. Chinese medicine treatment for patients with lung nodules requires evidence-based treatment and cannot be generalized. If a patient with lung nodules is characterized by phlegm congestion and qi reversal, with symptoms such as coughing, coughing up phlegm and shortness of breath, perilla can be used to alleviate the symptoms. However, for patients with severe lung nodules, it is not effective in relieving symptoms, and they need to consult with a medical professional and take active and correct corresponding treatment. In addition, the use of perilla seed alone is limited in active ingredients and cannot replace the therapeutic effect of multi-drug combinations. If you have any discomfort and need to use medication, please go to the hospital and use the medication under the guidance of the doctor’s diagnosis.
