Sichuan Fritillary (Fritillaria cirrhosa), known as "Chuan Bei Mu" in Traditional Chinese Medicine (TCM), is primarily used for its expectorant and antitussive properties, especially in treating coughs and certain respiratory conditions. There is some traditional mention of its use in clearing "heat" and "toxins," which, in TCM theory, may extend to conditions like conjunctivitis (eye redness and swelling), often classified as "wind-heat" invading the eyes. A few historical TCM texts suggest its use in multi-herb formulations for eye inflammation, but it is not a primary or commonly cited remedy for conjunctivitis. Instead, herbs like Chrysanthemum (Ju Hua) and Cassia seeds (Jue Ming Zi) are more directly associated with eye disorders in TCM practice.

Regarding scientific evidence, there are no robust clinical or pharmacological studies supporting the efficacy of Sichuan Fritillary for conjunctivitis. Research has focused on its effects on the respiratory system, antitussive activity, and some anti-inflammatory properties, but not specifically on ocular inflammation or conjunctivitis. Therefore, its use for conjunctivitis is justified by limited traditional references rather than scientific validation, and the overall evidence is weak.
