In this study, the pharmacological and toxicological effects along with possible side effects of the classical ayurvedic formulation "Lauhasava" (LSV), which is used in anemia, were evaluated. During this study, various experiments on body growth rate, organ-body weight ratio, tissue hydration indices and body fat ratio were performed to evaluate its efficacy and toxicity. In the body weight study, the LSV treated rats, irrespective of sexes, showed significantly lower body weights than the control group rats. LSV treated mice of both sexes gained less weight than their control counterparts. The study involving comparison of the relative weights of the major organs of rats and mice revealed some significant results. The percentage of lung to the body weight is significantly increased in both sexes of rats. Liver weight in LSV treated rats of both sexes were observed to be increased. The percentage of kidney weight was increased in both sexes of rats, the result being significant in the case of female rats. The thymus weight was found significantly decreased in both sexes of rats. Significant increase in the weight of rats' ovaries was observed. In the tissue hydration index experiment, only the increase in the female kidney was significant. No significant result was found in the fat content of the whole mice and eviscerated mice.
