Ageratum is an annual herb that grows about 60 cm high and produces small pretty pink flowers at the top of its hairy stems. In some countries it is considered a weed that is hard to control. Ageratum ranges from Southeastern North America to Central America, but the center of origin is in Central America and the Caribbean. Ageratum is also found in several countries in tropical and sub-tropical regions, including Brazil.
TRIBAL AND HERBAL MEDICINE USES
Ageratum is widely utilized in traditional medicine systems where ever it grows. In Brazil an infusion is prepared with the leaves or the entire plant and employed to treat colic, colds and fevers, diarrhea, rheumatism, spasms, and as a tonic. It is also highly recomended there for burns and wounds. In other countries in Latin and South America the plant is widely used for its antibacterial properties for numerous infectious conditions and bacterial infections. In Africa, ageratum is used to treat fever, rheumatism, headache, pneumonia, wounds, burns and colic.
Ageratum contains many bioactive compounds including flavonoids, alkaloids, cumarins, essential oils, chromenes, benzofurans, terpenoids and tannins. The main plant chemical found in the plant include: 6,7-dimethoxy-2,2-dimethylchromene, 6-demetoxyageratochromene,
6-vinyl-demethoxy-ageratochromene, ageratochromene, alpha-cubebene, alpha-pinene, alpha-terpinene, beta-caryophyllene, beta-cubebene, beta-elemene, beta-farnesene, beta-myrcene, beta-pinene, beta-selinene, beta-sitosterol, cadinene, caryophyllene-oxide, conyzorigin, coumarin, dotriacontene, endo-borneol, endo-bornyl-acetate, ethyl-eugenol,
ethyl-vanillin, farnesol, friedelin, HCN, hexadecenoic-acid, kaempferol, kaempferol-3,7-diglucoside, kaempferol-3-o-rhamnosylglucoside, linoleic-acid, quercetin,
quercetin-3,7-diglucoside, and quercetin-3-o-rhamnosylglucoside.
BIOLOGICAL ACTIVITIES AND CLINICAL RESEARCH
Laboratory research has validated several of ageratum's uses in traditional medicine.
Test tube studies (in vitro) have reported that extracts of the whole plant have an antibacterial action against Staphylococus aureus, Bacillus subtilis, Eschericichia coli, and Pseudomonas aeruginosa. In animal studies, it demonstrated a muscle relaxing and pain relieving effect, confirming its popular use for rheumatism. In Brazil, a water extract of the whole plant was given to human patients with arthritis; 66% reported a decrease in pain and inflammation and 24% reported an improvement in mobility after one week of treatment without side effects. Researchers in Africa confirmed its traditional uses for wound healing in animal studies with rats in 2003. Other research in India reported that ageratum protected mice from radiation damage and prevented ulcers in mice. Both cellular protection actions were attributed, in part, to an antioxidant effect noted for ageratum. Scientists have also discovered that ageratum has an insecticidal effect by interfering with the reproductive cycles of many species of insects. Acute and chronic toxicity studies were conducted in Brazil with rats and researchers reported that ageratum was non-toxic at all dosages tested.
