Mortality time of parasitic leeches treated with different concentrations of aqueous extract of A. indica.

No	Group	Mortality Time (min) Mean ± S. D	Mortality (%)
1	Normal control	720.00 ± 00	0
2	Positive control (Formalin 0.25%) (v/v)	3.77 ± 0.25 #	100
3	A. indica (25 mg/mL)	42.65 ± 9.20 #,$	100
4	A. indica (50 mg/mL	11.69 ± 1.11 #,$,%,	100
5	A. indica (100 mg/mL)	6.45 ± 0.45 #,$,%,*	100

Each value represents the mean ± S.D. of six parasitic leeches per group. ^# Significance at p < 0.05 compared with the control group. ^$ Significance at p < 0.05 compared with the formalin-treated group (0.25% v/v); ^% Significance at p < 0.05 compared with A. indica (25 mg/mL); * Significance at p < 0.05 compared with A. indica (50 mg/mL).
