Does the subject want to ask "is it okay to take 20 grams of Radix Cyathulae and Radix Achyranthis Bidentatae each?" You can't. According to the official of the Fourth Affiliated Hospital of Liaoning University of Traditional Chinese Medicine, according to the pharmacopoeia, the dosage of Achyranthes bidentata 6 ~15g is within a reasonable range, and 20g is out of the range, so it is not allowed. Achyranthes bidentata has the effects of promoting blood circulation, dredging channels, nourishing liver and kidney, strengthening bones and muscles, and promoting urination.
