Arisaema amurense, commonly known as Chinese cobra lily, has been used in traditional Chinese medicine (TCM) for centuries. In TCM, the processed tuber of Arisaema species (often referred to as "Tian Nan Xing") is traditionally used to treat conditions associated with "phlegm," which includes symptoms like congestion, cough, and chest oppression. The herb is believed to have properties that "dispel wind-phlegm" and "relieve obstruction," according to classical medicinal texts such as the Shennong Bencao Jing and subsequent TCM materia medica.

Modern pharmacological studies on Arisaema amurense specifically are limited. Some studies on related Arisaema species and their crude extracts have shown anti-inflammatory and expectorant effects in animal models, which could theoretically contribute to relief of respiratory congestion. However, these studies are preliminary, often not specific to Arisaema amurense, and generally do not meet rigorous scientific standards for clinical efficacy. There are also toxicity concerns, as the raw tuber contains calcium oxalate crystals and requires careful processing before medicinal use.

In summary, while there is a strong historical precedent for the use of Arisaema amurense in managing congestion within traditional medicine systems, there is limited scientific validation to support its efficacy or safety for this purpose.
