We stopped by Aunt Bess 's house and she gave me a dose of the cure - all castor oil . Now castor oil is NASTY and if you were n't sick before , it would make you sick , believe me ! That dose of castor oil must have been a real cure because I did n't get sick at school again .
According to the above context, answer the following question.
Why does Aunt Bess prefer to use castor oil as a curative agent for sickness ?


She has seen success with the oil in her own health , so is passing on the cure
