Symptoms are identical to those of ricin, except abrin is more toxic by almost two orders of magnitude; the fatal dose of abrin is approximately 1 / 75th that of the fatal dose of ricin ( though the abrin in ingested seeds may be absorbed much more slowly than the ricin in " Ricinus communis " even if the seeds are chewed and the coat penetrated, allowing time for successful rescue efforts in at least some cases . ) Abrin has an of only 0.56 ?g / kg in mice, and Kingsbury lists a toxic dose in humans at 0.00015 % body weight, or approximately 0.1 mg for a 150 lb human.
