Semi-chronic toxicity: compared with the control group, a dose of 0.6g and 3g Soi rung granule / kg of rabbit weight (5 times greater than the clinical dose) was used for 8 weeks continuously, which caused microscopic morphological changes of the rabbits liver with different levels, which increased AST, ALT level (p < 0.05) but did not affect the metabolic function of liver, haematopoietic functions as well as function of glomerular filtration, macroscopic and microscopic morphological kidney of experimental rabbits (p > 0.05).
