Tibetan mother-of-pearl is not a cure for pulmonary nodules. Tibetan motherwort is a kind of endemic plant growing in the Tibetan plateau area, non-toxic, edible, belongs to a kind of food, not drugs, no drug efficacy and effect, so Tibetan motherwort has no therapeutic effect on patients with lung nodules. When patients are diagnosed with lung nodules, they should clarify the situation of the lesions in time, such as benign nodules, small lesions, can temporarily observe the changes in the condition, and need to be surgically resected when they grow up; such as malignant nodules should be operated as soon as possible, which can improve the prognosis, and blindly taking the Tibetan sweet mother of pearl can delay the condition and lead to adverse consequences. When patients are diagnosed with pulmonary nodules, they should standardize the treatment under the guidance of professional physicians, so as to avoid blind treatment, leading to adverse consequences.
