Each treatment consisted of three baths of 10 min at intervals of 24 h. The therapeutic solution was distributed at the edge of the tank: 14 mL of stock solution of L. sidoides; 28 mL of M. piperita solution; water alone; and water + 224 mL of DMSO. After the third bath, 10 fish from each replicate were collected for parasitological and hematological analysis.
