Synopsis

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

Bitter Grass (commonly referring to plants like Vernonia amygdalina or other regional species) has a history of use in traditional medicine for a variety of ailments, including respiratory issues such as congestion. In many African and Asian folk traditions, decoctions or infusions of bitter grass have been consumed or used as steam inhalations to help relieve symptoms associated with colds, coughs, and sinus congestion. The rationale in traditional medicine is often based on the plant’s perceived “cleansing” or anti-inflammatory properties, though the mechanisms are not well-defined.

However, scientific studies specifically investigating the efficacy of bitter grass for congestion are very limited. While some research has identified general antimicrobial, anti-inflammatory, and antioxidant properties in certain species (notably Vernonia amygdalina), there is little direct evidence to support its use for treating congestion in humans. Most available data come from in vitro or animal studies, rather than controlled clinical trials in people with upper respiratory congestion. Thus, while the use is justified by tradition, current scientific validation is weak or absent, and the overall evidence rating remains low.
