The so-called boneless plum mainly refers to a kind of plum with separated pulp and stone. From the point of view of traditional Chinese medicine, this kind of plum is flat and sweet, and has certain effects of clearing away heat and promoting diuresis, promoting fluid production to quench thirst, reducing swelling and relieving annoyance.
