Juglans cinerea Butternut is a mild cathartic and does not constipate. It is for this reason that it is frequently used as a habitual laxative. It has been used historically for the treatment of Dysentery and hypatic conditions and as a general vermifuge.

The Butternut (Juglans cinerea), also occasionally known as the White Walnut, is a species of walnut native to the eastern United States and southeast Canada, from southern Quebec west to Minnesota, south to northern Alabama and southwest to northern Arkansas. It is a deciduous tree growing to 20 m tall, rarely 30 m, and 40-80 cm stem diameter, with light gray bark. The leaves are pinnate, 40-70 cm long, with 11-17 leaflets, each leaflet 5-10 cm long and 3-5 cm broad.
