Fu Ling (Poria cocos) is a traditional Chinese medicinal fungus historically used in Chinese herbal formulas. Its primary traditional functions include promoting urination, strengthening the spleen, and calming the spirit. In Chinese medicine, swollen lymph nodes are often interpreted as a manifestation of "dampness" or "phlegm accumulation," sometimes associated with spleen deficiency or fluid retention. Fu Ling is commonly included in formulas to "drain dampness" and support the spleen, which, in TCM theory, is believed to influence the transformation and transportation of fluids, helping address swelling or edema. There is a long-standing historical precedent for using Fu Ling in formulas targeting glandular swellings, particularly when associated with dampness.

However, there is limited direct scientific evidence supporting Fu Ling’s efficacy for swollen lymph nodes specifically. Some in vitro and animal studies suggest that Poria cocos may have immunomodulatory and anti-inflammatory properties, but these studies are not directly linked to lymphatic or glandular swelling in humans. No robust clinical trials have specifically investigated Fu Ling for the treatment of swollen lymph nodes. Thus, its use for this purpose is primarily justified by traditional practice, not by modern clinical research.

In summary, Fu Ling's use for swollen glands is based on its historical application within TCM frameworks, with only indirect or preliminary scientific support for related actions such as reducing inflammation or modulating immunity.
