Zhejiang fritillary (Fritillaria thunbergii), known as "Zhe Bei Mu" in Traditional Chinese Medicine (TCM), has a long history of use for supporting the health of the mucus membranes, especially in the respiratory system. Traditionally, it is used to clear heat, moisten the lungs, and resolve phlegm, making it a common herbal remedy for symptoms like coughs with thick sputum, sore throat, and bronchitis. Classic TCM texts and modern herbal compendia cite its expectorant and antitussive properties, which are believed to help soothe and protect the mucus membranes lining the respiratory tract.

While contemporary pharmacological studies have identified some alkaloids in fritillary species that possess cough-suppressing and anti-inflammatory effects, most research is preclinical and limited in scope. There is some evidence from animal and in vitro studies demonstrating that Fritillaria extracts can reduce airway inflammation and mucus secretion, but robust clinical trials in humans are lacking. Thus, while scientific validation is emerging, current use to support mucus membranes primarily rests on centuries of traditional application and anecdotal reports rather than strong modern clinical evidence.

In summary, Zhejiang fritillary's use for mucus membrane support is deeply rooted in tradition, with moderate but not definitive scientific backing at present.
