Abstract: To understand the attitudes and perceptions of traditional Chinese medicine (TCM) practitioners in Beijing TCM hospitals regarding the use of Ephedra sinica Stapf ( E . sinica , Ma Huang). A two-stage cross-sectional study was conducted using a questionnaire survey of TCM practitioners in Beijing TCM hospitals between April 2023 and March 2024. The questionnaire included demographic information, the clinical background of TCM practitioners, and the clinical application of E . sinica . Logistic regression analysis was used to analyze the relevant influencing factors when using E . sinica . Of the 465 questionnaires collected, 441 were valid. Among these, 84.81% (374/441) reported having used E. sinica in clinical practice at least once. The commonly used doses of E. sinica —excluding the pediatric department—were 10 g for high doses, 6 g for medium, and 3 g for low. The three most frequently used formulas for E . sinica included Maxing Shigan decoction, Mahuang decoction, and Xiao Qing Long decoction. The most common TCM patterns treated with a high dose of E . sinica were wind-cold exterior pattern, wind-cold invading the lung, and wind and water combat with meridians congealed by cold. The top three Western medical diagnoses when using E . sinica for treatment were common cold, pneumonia, and upper respiratory tract infections. Nearly half of the respondents reported experiencing adverse reactions from the oral administration of E . sinica , with the most common being palpitations, insomnia, and restlessness. Starting with a low dose and gradually increasing it as appropriate was identified as an effective approach. This study investigated the attitudes and perceptions of TCM practitioners in Beijing TCM hospitals regarding the dose–efficacy–adverse reaction relationship of E . sinica , providing a reference for the safe and effective clinical use of E . sinica .
