Résumé
Rang Chued (Thunbergia laurifolia) is a Thai medicinal plant recognized for its antioxidant, detoxifying, and hepatoprotective properties [PMID:36518438, 29410686].
Contexte
Thunbergia laurifolia, also known as Rang Chued or Rang-jued, is a medicinal plant from the Acanthaceae family used in Thailand [PMID:36518438, 34829549].
Usages traditionnels
It is used in traditional Thai medicine as an antidote, for decreasing body temperature (antipyretic), to treat mouth ulcers, and as an herbal tea [PMID:36518438, 38735681, 35745006].
Composés actifs
Major bioactive compounds include rosmarinic acid, caffeic acid, and vicenin-2 [PMID:38735681, 34451693]. Other identified constituents include apigenin, gallic acid, carotenoids, chlorophylls (Pheophytin a and Hydroxy Pheophytin a), iridoid glucosides (8-epi-grandifloric acid and 3'-O-beta-glucopyranosyl-stilbericoside), and 5-acetoxyfuranonapthoquinone [PMID:38790743, 12150796, 36170203].
Mécanisme d'action
The herb acts by increasing antioxidant enzyme activities (SOD1, SOD2, CAT, GPx), reducing intracellular reactive oxygen species (ROS), and modulating the p62-KEAP1-NRF2 signaling pathway [PMID:34829549, 36309371]. It also induces the detoxifying enzyme NQO-1 in liver cells [PMID:38790743] and may inhibit MMP-1, MMP-2, and MMP-9 [PMID:32326348, 29410686].
Preuves cliniques
Preuve DLead-induced renotoxicity
Leaf extracts partially recovered renotoxicity by modulating cell signaling pathways in mice [PMID:34466056]
Preuve DParaquat-induced lung and kidney injury
Aqueous leaf extract alleviated lung injury by inhibiting oxidative stress and inflammation, and ameliorated kidney injury by regulating NADPH oxidase in rats [PMID:35317802, 35399379]
Preuve DAlcohol-induced hangover
Leaf extract administered prior to ethanol increased locomotor activity and reduced blood ethanol levels and liver enzyme changes in rats [PMID:40430504]
Preuve DGestational Diabetes Mellitus (GDM)
Ethanolic extract significantly reduced blood glucose and increased insulin levels in a rat model [PMID:38941042]
Preuve DCognitive and emotional deficits
Leaf extract reduced cognitive deficits in olfactorectomized mice [PMID:25609149]
Preuve DCadmium toxicity
Sécurité et effets indésirables
Acute toxicity studies in Wistar rats using oral gavage of water, ethanol, and acetone extracts at doses up to 15,000 mg/kg did not report immediate lethal toxicity [PMID:36518438]. Chronic oral administration (30 days) at 1 and 10 g/kg did not cause addiction behavior in rats [PMID:26817209].
Grossesse et allaitement
A study in a rat model of gestational diabetes showed that T. laurifolia extract reduced blood glucose and increased insulin levels from gestation day 7 until term [PMID:38941042].
Synthèse des preuves
The current evidence consists primarily of in vitro cell studies and in vivo animal models (rats, mice, ducks, rabbits). There is a lack of human clinical trial data.
