In general, whether drinking water infused with Prunella vulgaris (Summer枯Herb) is effective for pulmonary nodules depends on the specific condition of the nodule. Details are as follows:

For benign pulmonary nodules caused by a heat-related constitution, Prunella vulgaris may have certain supportive effects if approved by a physician. This herb is cool in nature and possesses properties that clear heat and dissipate nodules. For small benign nodules resulting from internal damp-heat or phlegm-fire stagnation, drinking Prunella vulgaris infusion under medical guidance can serve as a complementary调理 approach. However, regular follow-up examinations are necessary to monitor any changes in the nodule.

Prunella vulgaris should not be used if the nature of the pulmonary nodule is unclear or malignancy is suspected, or if the patient has a deficient-cold constitution. The herb cannot inhibit the growth of malignant nodules, and consuming it blindly may delay standard medical treatment. Individuals with a cold-deficient constitution may experience abdominal pain, diarrhea, or other discomfort after consumption. Moreover, Prunella vulgaris has no clear regulatory effect on solid nodules with indistinct borders and may interfere with accurate assessment of the condition.

Always consult a qualified physician before consuming any herbal remedy—do not self-medicate. Maintain a regular sleep schedule, avoid staying up late and excessive fatigue, quit smoking, and stay away from dusty environments. Eat a light diet rich in fresh fruits and vegetables, reduce intake of spicy and irritating foods, and strictly follow medical advice for regular check-ups, keeping records of changes in nodule size and morphology.
