Fu Ling (Poria cocos) is a well-known medicinal fungus in Traditional Chinese Medicine (TCM), where it has been used for centuries. Its traditional indications include promoting urination, draining dampness, strengthening the spleen, and calming the spirit. In TCM, kidney infections are not described in the same biomedical terms as in Western medicine; however, symptoms such as urinary difficulty, cloudy urine, and swelling may be interpreted as manifestations of "damp-heat" or "dampness" affecting the urinary tract or kidneys. Fu Ling is commonly included in herbal formulas intended to "drain dampness" and "support kidney function" according to TCM theory. It is regarded as a mild diuretic and is often combined with other herbs to treat urinary tract symptoms, which could overlap with kidney infection presentations.

There is limited scientific evidence supporting Fu Ling's efficacy specifically in treating bacterial kidney infections (pyelonephritis) as defined by modern medicine. Some laboratory studies suggest Poria cocos may have anti-inflammatory, immunomodulatory, and mild antimicrobial properties, but these findings do not directly translate to clinical efficacy for kidney infections. Therefore, its use is primarily justified by tradition, with a low level of scientific evidence supporting its application for this condition.

In summary, Fu Ling's use for kidney infection is rooted in traditional practice rather than robust scientific validation. Anyone considering using it for this purpose should consult a healthcare practitioner, especially since kidney infections can be serious and typically require prompt medical treatment with antibiotics.
