The experimental design in the study

Groups	Drug	Dosage ( mg/kg )	Average volume per rat (mL)
A	CMC-Na	50	1.74
B	Eugenol	50.3	1.63
C	Aspirin	55.2	1.73
D	AEE	50	1.65
E	AEE	100	1.72
F	AEE	200	1.76
G	Aspirin + eugenol	55.2 + 50.3	1.68

Note: A: CMC-Na group, B: model group, C: aspirin group, D: AEE low dose, E: AEE medium dose, F: AEE high dose, G: Ratio 1:1, integration of aspirin and eugenol, molar ratio 1:1, 0.3067 mmol. In order to compare the difference between AEE and its precursors, the mole of the doses in medium-dose of AEE, aspirin and eugenol groups are the same as 0.3067 mmol. The averaged intragastrically volume in different groups were approximate equal
