Synopsis

Source of validity: Traditional
Rating (out of 5): 2

Tree Peony (Paeonia suffruticosa) root bark, known as "Mudanpi" in Traditional Chinese Medicine (TCM), has a long history of use in East Asian herbal medicine. In TCM, it is often incorporated into herbal formulas for its purported ability to "clear heat" and "cool the blood," which are concepts related to reducing inflammation and infection. Conjunctivitis, described in TCM as "red, swollen eyes" due to "wind-heat" or "liver fire," is sometimes treated with formulas containing Tree Peony, such as "Long Dan Xie Gan Tang." However, the use is based primarily on traditional theory rather than modern pharmacological evidence.

Scientific research on Tree Peony’s direct effects on conjunctivitis in humans is lacking. Some laboratory studies suggest that compounds in Tree Peony root bark (such as paeonol) have anti-inflammatory and antimicrobial properties, which could theoretically benefit inflammatory eye conditions. Yet, these findings are mostly preclinical and have not been validated in clinical trials specific to conjunctivitis. Thus, while Tree Peony is traditionally used in herbal medicine for eye inflammation, the evidence supporting its efficacy for conjunctivitis is weak and primarily based on historical usage rather than robust scientific validation.
