Rating (out of 5): 1

Bitter Grass (commonly referring to species such as Andropogon virginicus or related grasses) has been used in certain traditional medicine systems, most notably in some regions of Africa and Asia, for its purported health benefits, including use as a remedy for congestion and conditions believed to involve the lymphatic system. Historical records and ethnobotanical surveys indicate that decoctions or infusions of Bitter Grass have been used as part of folk medicine to "clear blockages" or "purify the blood," which, in traditional frameworks, may refer to symptoms of lymphatic congestion or related disorders. However, there is a lack of clarity and consistency about which specific plant is being referenced as "Bitter Grass," and no rigorous clinical studies have been conducted to validate these uses. The evidence supporting its effectiveness is thus weak, consisting primarily of anecdotal accounts and traditional practices rather than scientific validation. No significant bioactive compounds with proven lymphatic effects have been isolated from Bitter Grass in peer-reviewed research. Therefore, while there is some documentation of its use in traditional medicine for congestion-like symptoms, modern scientific evidence is lacking, and the historical evidence is limited in both scope and quality.
