Resources and utilization status of <italic>Daphniphyllum calycinum</italic>

As a key raw material for the Chinese patent medicine Fengliao Changweikang， the wild resources of Daphniphyllum calycinum are becoming increasingly difficult to harvest due to the continuous growth in market demand. The lack of breakthroughs in key technologies related to wild domesticated species has rendered large-scale industrial cultivation unachievable to meet medicinal requirements. This paper reviews the distribution status of wild resources of D. calycinum， the research progress in the cultivation technology of wild domesticated species， the application records in herbal literature of successive dynasties， the collection of local medicinal material standards， as well as the traditional medicinal efficacy， modern pharmacological research， and related preparation development status of D. calycinum， aiming to provide scientific basis for its resource protection and sustainable utilization.
