I can give you an authoritative answer, because I am a rural girl born and raised, the root of shepherd's purse must not go, nor because it is nutritious, even if it tastes bad, but it is nutritious and delicious. You can search on Taobao. The price of wild shepherd's purse with roots will be higher than that of ordinary shepherd's purse, so I will sell wild shepherd's purse on Taobao. My signature is wild shepherd's purse with long roots. Once a buyer contacted me after buying my shepherd's purse, saying that my shepherd's purse had too big roots but few leaves. She asked if the root could be eaten, and said that she would wait until the shepherd's purse leaves were bigger. I told her that shepherd's purse roots were edible. Immediately after she bought jiaozi, she bought five catties of shepherd's purse from my house, and later she bought 6438. 10 years, I ate fresh shepherd's purse again. I hope I can help you.
