Résumé
Hagenia abyssinica, commonly known as 'kosso', is a multipurpose tree species endemic to the highlands of Ethiopia used traditionally to treat various diseases [PMID:39769960, PMID:40642007].
Contexte
Hagenia abyssinica is a monotypic dioecious tree species from the Rosaceae family distributed in the highlands of Ethiopia [PMID:39769960, PMID:32308725, PMID:28097059]. It is utilized for medicinal purposes, furniture, fuel wood, soil fertility management, and rainwater conservation [PMID:39769960].
Usages traditionnels
Traditionally used in African countries to treat fever, abdominal pain, respiratory illnesses, intestinal parasitic infections, wound healing, cancer, and diabetes mellitus [PMID:40642007, PMID:39769960, PMID:33149648]. The flowers are specifically used as a tea for intestinal parasites [PMID:32041310] and for wound treatment [PMID:32308725].
Composés actifs
The plant contains secondary metabolites including terpenoids, flavonoids, and phenols [PMID:40642007]. Specific constituents include phloroglucinol derivatives (kosins), quercetin 3-O-β-glucuronide, quercetin 3-O-β-glucoside, and rutin [PMID:22896828]. Essential oil components include cis-davanone (14.73%), Aristolediene (9.31%), and cryptone (6.50%) [PMID:38938551].
Mécanisme d'action
Potential antiparasitic activity may involve the inhibition of target enzymes such as acetylcholinesterase (AChE), lactate dehydrogenases (LDH), and glutathione reductase (GR) [PMID:38763 la]. Antidiabetic effects are associated with the inhibition of α-amylase and α-glucosidase [PMID:33987444, PMID:32607006].
Preuves cliniques
Preuve DDiabetes Mellitus
Crude hydromethanol extract of leaves significantly reduced fasting blood glucose levels in streptozotocin-induced diabetic mice [PMID:33149648].
Preuve DDiarrhea
Methanol crude extract of leaves exhibited antidiarrheal activity in castor oil-induced mouse models [PMID:34055027, PMID:33628317].
Preuve DParasitic Infections
Fractions showed anthelmintic activity against Schistosoma mansoni, Clonorchis sinensis, Fasciola hepatica, and Echinostoma caproni, with activity decreasing as polarity increased [PMID:22896828].
Preuve DWound Healing
80% methanol crude flower extract was evaluated for wound healing and anti-inflammatory activity in mice [PMID:32308725].
Sécurité et effets indésirables
Crude extract is considered safe in vivo at doses less than 2,000 mg/kg [PMID:40642007, PMID:33628317]. However, larger doses can cause damage to the optic nerve [PMID:40642007], and high doses have been reported to cause retinal pathology and visual deficits in chicks [PMID:4060151].
Synthèse des preuves
The current evidence is primarily based on in vitro and in vivo animal models (Level D) and literature reviews (Level C). There is a lack of human clinical trials to validate traditional uses.
