Arisaema amurense, commonly known as Chinese cobra lily, is a plant traditionally used in Chinese herbal medicine. Historically, the tuber (often processed as "Tian Nan Xing") has been employed in traditional Chinese medicine (TCM) formulations to address respiratory conditions such as cough, phlegm, and bronchial congestion. Its reputed effects are primarily due to its ability to "dry dampness and expel phlegm," which aligns with TCM concepts rather than modern pharmacology.

The traditional use of Arisaema amurense for bronchial support is well-documented in classic Chinese materia medica texts, where it is frequently cited as an ingredient for treating issues related to excess mucus, asthma, and chronic bronchitis. However, its use is often cautioned due to the raw tuber's toxicity, and it is typically processed to reduce harmful effects before medicinal application.

Scientific validation for its efficacy in supporting the bronchial system is limited. Modern research on Arisaema amurense is sparse, with few studies addressing its pharmacological properties for respiratory health. Most available studies focus on related species or on isolated compounds with general anti-inflammatory or antitussive effects, but not specifically on its bronchial applications in humans. As such, its reputation for supporting the bronchial system rests mainly on traditional usage rather than robust scientific evidence.
