Polygonatum cirrhifolium, commonly known as "King Solomon's Seal," has a long history of use in various traditional medicine systems, particularly in Ayurveda and traditional Chinese medicine. In these traditions, the plant's rhizomes have been used for a range of ailments, including as a tonic for general weakness, for joint and bone health, and sometimes to address glandular swellings (including swollen lymph nodes). The rationale in traditional systems often relates to the plant’s reputed anti-inflammatory and adaptogenic properties, rather than any specific targeting of lymphatic tissue.

However, there is a lack of robust scientific studies directly validating the efficacy of Polygonatum cirrhifolium for treating swollen lymph glands. Most available information is anecdotal or based on broader traditional uses for "swelling" and "inflammation." No clinical trials or pharmacological studies have specifically addressed its effect on lymphatic swelling or lymphadenopathy. The evidence, therefore, is mainly traditional and not strongly supported by modern research.

In summary, while Polygonatum cirrhifolium is traditionally used for glandular swellings in some medical systems, scientific validation for this specific application remains minimal, and its use for swollen lymph glands should be regarded as based primarily on traditional knowledge rather than direct scientific evidence.
