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.
Mucilage, tannin, peptide alkaloids, adouetin X,Y,Y1, and Z, Quercetin.
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.

Uhaloa is a common tropical weed in the savannas of Suriname. It grows up to 6 feet tall and the plant mostly branches near the ground.
The whole plant is tomentose hairy while the serrate alternate leaves are bright green; underneath gray.
These leaves have conspicuous veins.
The fragrant flowers, growing in dense clusters in leaf axils, are yellow.
The small seed capsules hold one shiny black seed each.
In Polynesia the root bark (cortex) is chewed upon for sore throat, while in Hawaii it is used internally for arthritis, neuralgia and chronic cases of asthma.
An infusion of stem and leaves is also used.
Used against the common cold, diarrhea, unwanted pregnancy, painful menstruation and fatigue.
There is a possible presence of tannins; the plant is antibacterial and vericidal.
The leaves and buds are smoked to get a legal high.

• Anti-Inflammatory / Flavonoids: Study isolated three flavonoids from the whole plant of Waltheria indica. 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. Findings support the use of W indica for inflammatory diseases.
• Anti-Pneumococcal: Study of 221 crude extracts from 17 species showed 7 from 6 plants, including Waltheria indica, to have promising in vitro bactericidal activity against Pneumococcus, including penicillin-resistant strains. Results suppport its traditional use in the treatment of pneumococcal infections.
• Anti-Plasmodial: In a study of 13 extracts from 8 different species, five species, including W indica (roots and aerial parts) demonstrated moderate antiplasmodial activity.
