Yellow Ladyslipper
Cypripedium calceolus

Both the Pink and Yellow Ladyslippers, but more often the Yellow, have been widely used medicinally, although the harvesting of wild Ladyslippers is now prohibited due to their rarity. The Yellow Ladyslipper has also been called by the common name of American Valerian, because of its similar calmative effects. It was widely used during the 19th Century as a sedative and to relieve pain. Large doses can cause disorientation and headaches. All of the Ladyslippers may cause contact dermatitis.
