Oil of seed is taken for chronic inflammatory skin conditions. High in gamma-linoleic acid, which helps normalize hormones and blood pressure. Leaves and bark stem used for asthma. Evening primrose, also commonly called sundrop, hogweed, King�s cure-all, fever-plant and evening star, was used as food and medicine for centuries by native North Americans. All plant parts are edible. Oenethera biennis gets the common name evening primrose because it blooms after sunset and throughout the night, with the flowers closing up during daylight hours.
