CONVOLVULACEÆ.
Bindweeds (Convolvulus sepium L. and C. arvensis L.). The creeping rootstocks and foliage, as well as the seeds, are held to be more or less poisonous if eaten in quantity, and as long ago as 1872 Olver recorded (Veterinarian, 1872) that pigs which ate freely of Convolvulus died. These species, when eaten in considerable quantity, appear to be cathartic and purgative, causing symptoms resembling those due to jalap.
