Function of Gastradia Elata Extract

(1) Sedation: Tianma extract can counteract the central excitatory effect caused by caffeine. Can significantly antagonize pentylenetetrazol-induced convulsions, prolong the latency period of convulsions, reduce mortality or increase the amount of half-convulsions. Aspalathin can significantly reduce the role of glutamate (excitatory amino acids), reduce the glutamate-induced lactate dehydrogenase (LDH) leakage and neuronal cell mortality.

(2) anti-inflammatory and analgesic: Tianma on a variety of inflammatory reactions have inhibitory effects, can reduce capillary permeability, directly against 5-HT and prostaglandin E2 inflammatory response. Tianma on a variety of experimental pain has an inhibitory effect
