Consult personally

Haven't described about delivery normal or cesarean. Was ther any complications or when was the delivery.  Need to know your body type. Dasamularista is commonly used during post partum care. But the initial care should be within 15days lest any complications. The health of new born also matters. The type of food you are taking at present etc.

Consult ayurveda physician for proper diagnosis and root cause of ailment before consuming any medicine

You can use Dashmool decoction after delivery because it helps strengthen the uterus, and it is also very beneficial if you develop a fever. However, if you have a Pitta-dominant constitution, or if you experience mouth ulcers or watery, burning stools, then you should avoid using it.

You can start taking dashamularishta after 40 days post delivery. Not immediately. Take 20ml and after meals twice with lukewarm water. Yes you can even take Balant kadha together with it.
