Looking at the horoscope of your daughter, it is seen that she is in the mahadasha of Saturn and the antardasha of Mercury . Mercury is debilitated but conjoined with Exalted Venus , therefore its debilitation gets cancelled. The period of the 8th house is considered to be bad on the health front. How bad it can be no one known. I can tell you that there is no method to measure if their is any threat to life or not, and such period which can be considered bad come many times in a natives life. I mean if it was so simple then probably man would have become God. I can only suggest that as it is said that the 8th lord period is not good, you take good care of her and on every Saturday donate something from her hands. As her lagan lord is Moon and it is well placed and strong. Make her wear a silver kara (bangle). Have faith in God all will be fine, and there is no need to panic and have sleepless nights.
