Identification

Biological Activities

Compounds

Gastrodia is a traditional Chinese herbal medicine that serves as the natural source of the active compound gastrodin. Recent research highlights the significant pharmacological potential of gastrodin, particularly in its ability to enhance neural functions. In studies involving Alzheimer's disease models, this compound was shown to improve learning and spatial memory by reducing neuroinflammation and tau pathology. Furthermore, gastrodin helps restore the structure and function of neurons and the blood-brain barrier by inhibiting specific inflammatory pathways. These findings suggest that the gastrodin found within Gastrodia may eventually serve as an effective therapeutic agent for treating neurodegenerative diseases.

Conditions

Gastrodia serves as a potential therapeutic agent for treating Alzheimer's disease by enhancing learning and spatial memory. It effectively treats Aβ42-induced increases in ADRA1/NF-κB/NLRP3 protein expression through the inhibition of specific inflammatory pathways. The plant also treats BBB dysfunction by restoring tight junction protein expression and improving overall barrier function. Additionally, Gastrodia treats Tau pathology by reducing p-Tau protein expression in the hippocampus and cortex. Finally, the plant treats symptoms of motion sickness induced by rotation, such as impaired locomotion and conditioned taste aversion.
