Résumé
Plectranthus barbatus (synonym Coleus forskohlii) is a medicinal herb from the Lamiaceae family used traditionally for various respiratory, cardiovascular, and digestive ailments [PMID:20178070, PMID:31989223].
Contexte
Plectranthus barbatus, also known as Coleus forskohlii or Brazilian boldo, is a tropical perennial herb belonging to the Lamiaceae family [PMID:20178070, PMID:31803808, PMID:38024105]. It is widely cultivated in India and used in Hindu, Ayurvedic, and folk medicine across Brazil, tropical Africa, and China [PMID:20178070, PMID:31803808].
Usages traditionnels
Major ethnobotanical uses include treating intestinal disturbances, liver fatigue, respiratory disorders, heart diseases, and certain nervous system disorders [PMID:20178070, PMID:20186655]. It is also used for bronchitis, asthma, hay fever, angina, and abdominal disorders [PMID:31989223].
Composés actifs
The plant contains essential oils, abietane diterpenoids, and 8,13-epoxy-labd-14-en-11-one diterpenoids [PMID:20178070, PMID:20186655]. A primary active constituent is forskolin, a labdane-type diterpenoid found exclusively in the cork tissue of the roots [PMID:33928347, PMID:32893572, PMID:36985280]. Other identified compounds include flavonoids, cinnamic acid derivatives, and organic acids [PMID:38024105].
Mécanisme d'action
Forskolin acts by stimulating the enzyme adenylate cyclase, which increases the concentration of cyclic adenosine monophosphate (cAMP) [PMID:23023353, PMID:25726172, PMID:38623169]. In the eye, this activates the ciliary epithelium to reduce aqueous humor inflow, thereby decreasing intraocular pressure [PMID:23023353].
Preuves cliniques
Preuve CGlaucoma
Topical application of forskolin is capable of reducing intraocular pressure in humans, rabbits, and monkeys [PMID:23023353].
Preuve DHypertension
Hydroethanolic extract of P. barbatus leaves promoted an endothelium-dependent vasodilator effect in the aorta of spontaneously hypertensive rats [PMID:38024105].
Preuve DAllergic Bronchospasm
Intravenous or intratracheal administration of forskolin prevented bronchospasm in sensitized guinea pigs in a dose-related fashion [PMID:2410281].
Sécurité et effets indésirables
A cytogenetic assay in Allium cepa indicated that forskolin may cause genotoxic effects, including significant reductions in mitotic index and increased frequency of chromosome aberrations [PMID:25726172].
Interactions médicamenteuses
Forskolin may act synergistically with epinephrine, ephedrine, and pseudoephedrine [PMID:23023353]. It may enhance the effects of anti-clotting medications such as warfarin, clopidogrel, aspirin, and enoxaparin [PMID:23023353].
Synthèse des preuves
Evidence consists primarily of pharmacological reviews, in vitro studies, and animal models (D), with some clinical review data (C) regarding glaucoma. There is a lack of high-level human clinical trials (A/B) in the provided text.
