Arisaema erubescens, also known as "Cobra Lily" or "White-Flowered Arisaema," is a plant used in traditional medicine systems, particularly within Ayurveda and Traditional Chinese Medicine (TCM). In these systems, various species of Arisaema have been used for respiratory ailments, including bronchial conditions such as coughs, bronchitis, and asthma-like symptoms. The tuber, after proper processing to reduce toxicity, is typically the medicinal part used. In TCM, similar species like Arisaema consanguineum (part of the same genus) are used to "resolve phlegm" and "open the orifices," which broadly translates to supporting bronchial and respiratory health.

However, there is only limited scientific research specifically addressing Arisaema erubescens and its effects on the bronchial system. Most available evidence is anecdotal or based on traditional usage rather than modern pharmacological studies. Some preliminary studies on related species suggest possible anti-inflammatory and expectorant effects, but clear, targeted evidence for bronchial support in humans is lacking. Additionally, the plant contains toxic compounds that require careful processing before medicinal use, emphasizing the need for caution.

In summary, the use of Arisaema erubescens for bronchial support is primarily justified by traditional knowledge rather than robust scientific validation.
