Japanese Ladyslipper
Cypripedium japonicum
Cypripedium japonicum, a species of orchid native to Japan and parts of China, is not traditionally used in any known medical or folk practices. Scientific studies have identified key mycorrhizal fungi such as Lycoperdon nigrescens and Russula violeipes that are crucial for the growth of this plant. Additionally, a study found that South Korean households value conserving Cypripedium japonicum at an average annual willingness to pay of KRW 3,770. Research has also noted gray mold disease on the plant, likely caused by a strain of Botrytis cinerea. The chromosome count for Cypripedium japonicum is diploid with 2n = 2x = 22 chromosomes. No major safety concerns or known drug interactions have been recorded for this species.
