Beneficial effects of Haritaki in Alzheimer's disease
Terminalia Chebula: Alzheimer
Scientific experiments and studies on the beneficial effects of Haritaki in Alzheimer's disease.
The studies confirm a neuroprotective efficacy of Haritaki. Furthermore, Haritaki extracts and their constituents AChEI are shown to have both antioxidant and anti-inflammatory effects, which are currently important for the treatment of Alzheimer's disease.
Neuroprotective effect of Terminalia Chebula extracts and ellagic acid in PC12 cellsAfrican Journal of Traditional Complementary Alternative Medicine 2017 Jun 5;14(4):22-30. doi: 10.21010/ajtcam.v14i4.3. eCollection 2017.
The methanolic and water extracts of Terminalia chebula and ellagic acid exhibited the strongest neuroprotective activity against Aß25-35-induced PC12 cell damages at 0.5-5.0 µg/ml. The ellagic acid also exhibited partial neuroprotective activity against H2O2-induced PC12 cell damages at 0.5-5.0 µg/ml. The methanolic and water extracts of T. chebula and ellagic acid protected PC12 cells from Aß25-35-mediated cell damages and enhanced cell viability thorough two key mechanisms by: (1) inhibiting ROS production and (2) reducing calcium ion influx. Conclusion: The T. chebula represents a promising plant-source as medicine in the application for the treatment of AD. Further investigation focusing on the active component of T. chebula extracts e.g., ellagic acid is crucial to verify the neuroprotective efficacy and mechanisms in vivo.[Link to the scientific study]
A Review on Potential Mechanisms of Terminalia chebula in Alzheimer's DiseaseAdvances in Pharmacolgical Sciences 2016;2016:8964849. doi: 10.1155/2016/8964849. Epub 2016 Jan 28.
The current management of Alzheimer's disease (AD) focuses on acetylcholinesterase inhibitors (AChEIs) and NMDA receptor antagonists, although outcomes are not completely favorable. Hence, novel agents found in herbal plants are gaining attention as possible therapeutic alternatives. The Terminalia chebula (Family: Combretaceae) is a medicinal plant with a wide spectrum of medicinal properties and is reported to contain various biochemicals such as hydrolysable tannins, phenolic compounds, and flavonoids, so it may prove to be a good therapeutic alternative. In this research, we reviewed published scientific literature found in various databases: PubMed, Science Direct, Scopus, Web of Science, Scirus, and Google Scholar, with the keywords: T. chebula, AD, neuroprotection, medicinal plant, antioxidant, ellagitannin, gallotannin, gallic acid, chebulagic acid, and chebulinic acid. This review shows that T. chebula extracts and its constituents have AChEI and antioxidant and anti-inflammatory effects, all of which are currently relevant to the treatment of Alzheimer's disease.[Link to the scientific study]
Terminalia chebula extract prevents scopolamine-induced amnesia via cholinergic modulation and anti-oxidative effects in miceBMC Complement Alternative Medicine 2018; 18: 136.
Terminalia chebula Retz. (Combretaceae) is a traditional herbal medicine that is widely used in the treatment of diabetes, immunodeficiency diseases, and stomach ulcer in Asia. However, the anti-amnesic effect of T. chebula has not yet been investigated. The present study was designed to determine whether T. chebula extract (TCE) alleviates amnesia induced by scopolamine in mice. We also investigated possible mechanisms associated with cholinergic system and anti-oxidant effects.
