Overview A tropical shrub, the whole plant (roots, leaves, buds and flowers) is used against chronic asthma. 
This plant has anti inflammatory and antifungal properties. Other uses include: cortex (root bark); chewed as a very effective natural medicine for sore throat. Internally for arthritis, neuralgia, common cold, cough, bronchial phlegm or mucous, diarrhea, eye baths, fatigue; used as a bitter tonic. Waltheria is used in Brazil against bronchitis and for cleaning difficult healing wounds. Used in the Caribbean for bladder infections. This is one of the best plant medicines for sore throats and a good herb for bronchial or bacterial infections. Phytochemicals Mucilage, tannin, peptide alkaloids, adouetin X,Y,Y1, and Z, Quercetin. Pharmacology In a study of several extracts from different species, five species, including Waltheria (roots and aerial parts) demonstrated moderate antiplasmodial activity. Study of crude extracts from 17 species showed Waltheria to have promising in vitro bactericidal activity against Pneumococcus, including penicillin-resistant strains. In a study three flavonoids were from the whole plant of Waltheria. The flavonoids showed significant dose-dependent inhibition of the production of inflammatory mediator NO, cytokines (TNF-a) and interleukin (IL-12) in activated macrophages, without displaying cytotoxicity. The findings support the use of this plant for inflammatory diseases. Quercetin is a ubiquitous bioflavonoid* with powerful activity against the production of pro-inflammatory cytokines in macrophages stimulated by lipo-polysaccharide. A mixture of bioflavonoids from Waltheria americana a plant used for centuries in India for inflammatory disorders, was found to significantly and dose-dependently inhibit the production of the nitric oxide (NO) and the cytokines tumor necrosis factor-a and interleukin (IL)-12, in lipopolysaccharide and g interferon activated murine peritoneal macrophages, without displaying cytotoxicity (cytotoxicity means being toxic to cells). The major constituent of extracts of this was quercetin. The flavenoid constituents 5,2?, 5?- trihydroxy-3,7,4?-trimethoxyflavone and 5,2,?-dihydroxy-3,7,4?,5?- tetramethoxyflavone show strong antifungal activity. *Bioflavonoids are a large, heterogeneous group of pigmented plant molecules; they may have emerged because of their ability to cope with the immense free radical load associated with photosynthesis. They are polyphenols, but beyond that they have a wide structural diversity. Over 4000 bioflavonoids have so far been described.
