Synopsis

Source of validity: Traditional
Rating (out of 5): 1

Chinese Rhubarb (Rheum palmatum) has a long history of use in Traditional Chinese Medicine (TCM), where it is known as "Da Huang." In TCM, bloodshot eyes are often considered a manifestation of internal heat, liver heat, or accumulation of toxins. Chinese Rhubarb is used primarily for its purgative and heat-clearing properties, and is sometimes included in herbal formulas aimed at "clearing heat" from the liver to alleviate symptoms such as redness of the eyes.

Despite its traditional use, there is little to no robust scientific evidence supporting the efficacy of Chinese Rhubarb specifically for treating bloodshot eyes. Most modern research on Chinese Rhubarb focuses on its laxative effects and its potential as an anti-inflammatory or antimicrobial agent. The use for eye redness is rooted in traditional diagnostic frameworks rather than evidence-based clinical trials. Thus, its use for this particular symptom remains primarily traditional, and the evidence supporting its effectiveness for bloodshot eyes is weak.
