Study Findings
• Antibacterial / Phytochemicals: Phytochemical testing of dried leaves yielded resins, alkaloids, saponins, tannins, glycosides and flavonoids while dried stems showed resins, saponins, tannins, glycosides and flavonoids. In vitro studies of AC extracts activity against S aureus, Y enterocolitica, S gallinarum, and E coli, suggesting a potential source for development of new antibacterials.
• Antiulcerogenic / Gastroprotective: Study documents the beneficial cytoprotective effects of the plant extract against ethanol-induced gastric ulcers in rats.
• Analgesic / Antiinflammatory: Study results suggested that AC extract exhibited antinociceptive effect and inhibition of inflammatory reactions induced by neutrophil mobilizing stimuli.
• Antimicrobial: Crude extract studies demonstrated antimicrobial properties on S aureus and Methicillin-resistant S aureus and possible usefulness in skin and wound infections.
• Hemostatic: Study yielded tannins, saponins and flavonoids and confirmed the hemostatic activity of the leaf extract through vasoconstriction and formation of an “artificial clot” to arrest the small vessel bleeding.
• Radioprotective: Study of AC extract showed it to be non-toxic at its highest dose and exhibiting a radioprotective activity in part attributed to the scavenging of reactive oxygen species induced by ionizing radiation.
• Wound Healing: Extract study showed wound healing effect better than normal saline treated controls, an effect attributed to the antimicrobial properties of AC.
• Blood Glucose Lowering / Leaves: Study of aqueous extracts of leaves of Ageratum conyzoides in normoglycemic and STZ-induced diabetic rats showed significant reduction of blood glucose levels.
Study of aqueous extracts of leaves of Ageratum conyzoides in normoglycemic and STZ-induced diabetic rats confirmed the hypoglycemic properties of the leaves of A conyzoides.
• Anti-Inflammatory / Toxicity Study: Study confirmed the anti-inflammatory properties of A conyzoides with no apparent hepatotoxicity.
• Anti-Cancer / Radical Scavenging Activity: Various extracts of A conyzoides were screened in some cancer lines including Human non-small cell lung CA, human colon adenocarcinoma, human gastric CA, and human breast CA among others. Results showed A conyzoides possessed anticancer and antiradical properties.
• Toxicity Study: A 28-day study evaluated the acute and sub-chronic toxicity of A. conyzoides leaves in Wistar rats. Results showed the hydroalcoholic extract is relatively safe when administered orally to rats.
• Comparative Study / Wound Healing / Polyherbal Formulation / Roots: Study in rats of root extract showed wound healing activity, with accelerated healing processes and increased breaking strength. The wound healing of a polyherbal formulation, Ageratum conyzoides with Ficus religiosa, C. longa and T. indica showed better results, attributed to the synergistic action of the plant constituents.
• Chemical Profiles of Leaf, Stem, Root, and Flower: In a study evaluating the chemical profile of plant parts, the leaf showed the most concentration of chemicals, followed by the flower.
• Antioxidant / Leaf / Improved Glycemia: The antioxidant activity of aqueous extract of leaves of Acin the serum of male diabetic rats was evaluated. Results showed lowering of lipid hydroperoxides. Ac had a positive effect on the oxidation-reduction system on STZ-induced diabetic rats, together with improved glycemia.
• Wound Healing Comparative Study / Vs Honey: Study in Wistar rats investigated the wound healing properties of methanolic extracts of Ac compared to honey. Histologically, the day-10 Ageratum sections showed fewer inflammatory cells compared with honey and controls. Also, healed scar sections of wounds dressed with herb extract showed more fibrosis. Healed wounds from Ac group showed significantly fewer fibroblasts.
• Diuretic Activity: Study of aqueous extract of leaves of Ac in albino Wistar rats showed significant diuretic activity. similar to Acetzolamide. at 600 mg/KBW, there was significant increase in concentrations of Na, K, and Cl ions suggesting benefits for hypertension and cardiovascular diseases.
• Lactation Effect: Study evaluated the effect of Ac leaf extract on the histological structures of non-lactating mammary gland of wistar white female albino rats. After 14 days of treatment, female rat mammary gland showed more secretory activity indicating lactation.
• Methoxylated Flavonoids / Antiprotozoal: The dichlormethane extract from aerial parts have shown prominent activity against bloodstream forms of Trypanosoma brucei rhodesiense, the etiologic agent of East African Sleeping Sickness. Study isolated five highly methoxylated flavonoids along with the chromene derivative encecalol methyl ether. The flavonoids showed activity against protozoan pathogens.
• Haemostatic Effects: Study of methanolic leaf extract in albino rats exhibited haemostatic effects. Results showed significant dose-dependent decreases in the bleeding time, prothrombin time, and clotting time, with a significant increase in plasma fibrinogen concentration. Results suggest haemostatic activity in both intrinsic and extrinsic pathways.
• Psychopharmacologic Effects / Memory / Ach: In a study in mice, Ac produced dose-dependent improvement in learning capacity and retention memory of both young and aged mice. It also reversed scopolamine and natural ageing-induced amnesia in young and old mice, while also indirectly increasing the acetylcholine by reducing the whole brain anticholinesterase activity.
• Inflammatory Bowel Disease / Protective Effects: In a study of acetic acid-induced colitis and indomethacin-induced enterocolitis models in rats, pretreatment with an ethanolic extract produced significant attenuation in biochemical and histopath parameters. Results suggest a possible benefit for use in inflammatory bowel disease.
• Pyrrolizidine Alkaloids in Medicinal Tea: Asteraceae is described as containing toxic pyrrolizidine alkaloids. Evaluation of aqueous extracts of Ageratum conyzoides detected pyrrozilidine alkaloids lycopsamine, dihydrolycopsamine, and acetyl-lycopsamine and their N-oxides. Lycopsamine and its N-oxide are known hepatotoxins and tumorigens. At the time of the report, there are no established safety guidelines on pyrrozilidine alkaloids-containing plants, and their use in Brazil.
• Toxicity Study: Study evaluated the mean lethal dose of an ethanolic extract of Ageratum conyzoides at a daily dose of 500 and 1000 mg kg of extract for 28 days. Results showed no toxic effects in rates, with an LD50 of 10,000 mg kg. Results suggest AC s safe for use in ethnomedicine.
• Antihyperglycemic: Study of crude extracts of leaves and fractions of A. conyzoides in rats showed important antihyperglycemic potential. Result suggest more than one antihyperglycemic compound with different chemical characteristics and mechanisms of action.
• Antioxidant / Cytotoxic: Study evaluating a methanolic extract of A. conyzoides stems for antioxidant activity using a DPPH scavenging assay showed dose dependent scavenging of free radicals. Cytotoxicity evaluation using brine shrimp lethality assay exhibited promising cytotoxicity, comparing with LC50 values of vincristine sulphate.
• Hepatoprotective / Acetaminophen Toxicity: Study evaluated the hepatoprotective effect of acetone and n-hexane extracts of A. conyzoides in wistar rats following acetaminophen induced hepatotoxicity. Results showed restoration of enzyme levels as indication of stabilization of plasma membrane as well as repair of hepatic tissue damages induced by APAP.
• Ovicidal / Larvicidal / Parasitic Nematode Heligmosomoides Bakeri: Study showed aqueous and ethanolic extracts of A. conyzoides have potent anthelmintic activity. The ovicidal activity could be due to penetration of egg shells, segmentation of blastomeres, or paralyses of larvae inside embryonated eggs.
• Anthelmintic / Schistosomicidal / Essential Oil: Study evaluated the schistosomicidal effects of the essential oil of A. conyzoides against adult worms of Schistosoma mansoni. Ac-EO showed activity, although less effective than the positive control, praziquantel (PZQ). Ac-EO caused dose-dependent reduction in the number of eggs. Precocene I and (E)-caryophyllene were identified as two major constituents.
