Question

How many times can the breastmilk soup be boiled? There’s not enough water, and my family has some herbal medicine that can be used for making soup, which includes ingredients like Poria cocos. It’s mainly for increasing milk supply. When making the soup, one dose of the medicine is divided into two parts, and half of it is cooked with pork ribs using a pressure cooker. I want to ask, for this type of medicine that is used to increase milk supply, how many times can it be boiled in the pot before it should be discarded? Can it be cooked in a pressure cooker? At 6 months old, is it still effective to increase milk supply at this time?
