Gui Pi Tang

Improve memory: The effect on mice memory behavior was observed by methods of jumping over plates, escaping from dark, and water maze boxes. This demonstrated that the capability of the mice memory was improved by endogastric infusion of 15.0g (raw herbs)/kg of the formula. This formula can reduce the antagonizing effects of scopolamine on the mice memory capability.(2)

Modified Gui Pi Tang can improve memory defects in aged mice. Muscarine induced cholinergic receptor activity and CAT activity in the mice forebrain and cerebral cortex markedly increased.(3)

Affect on immunology and reaction to stress: This decoction and the ethanol extract of it, may promote the phagocyte cellular functions and reactions to stress.(4) It has been demonstrated that in mice, the time period of swimming was prolonged. These results showed tolerance to anoxia, low and high temperatures.(5)

Counteracting a gastric ulcer: The inhibitory effects of Gui Pi Tang on acute stress ulcers and ulcer formation by reserpine were significant, but it was not effective on pylorus ligature ulcer formations. There was not any effect on amount of gastric juice secretion or excretion of pepsin. This mechanism of anti-ulcer effectiveness is perhaps related to inhibition of the central nervous system.(6)

Gui Pi Tang used singly or in combination, can inhibit gastric evacuation in mice with Da Huang induced spleen deficiency, as shown in the increase of the methyl orange residual rate.(7)

Counteracting anemia: The hemoglobin content in hemorrhagic anemic mice may be increased by this formula.(8) Hemoglobin and erythrocyte count in the mice model with a deficiency in blood may be increased by granular form of Gui Pi Tang used in either large or moderate dosage. Sleep time in mice was prolonged when Gui Pi Tang was administered. Mice spontaneous motility time and forelimb lifting time was reduced. The Concentration of specific antibody (hemolysin) increased and swimming time and survival period in anoxia was prolonged.(9)

Other effects: When administered orally to mice, Gui Pi Tang did not result in any toxic effects on the pregnant mice or any lethal and teratogenic effects on the fetus.(10)
