We recognize that creature have found way to get themselves intoxicated or gamy by eat up certain plant or ferment yield , but recently , scientist have start studying the ego - medication of animals — a subdivision of skill nickname zoopharmacognosy . This is how we get a line elephant might have a way to contribute on labor .
Researcher H. T. Dublin expend a year observing a group of elephant . She charted their regular diet , and the paths they walk to see intellectual nourishment . One day , a female elephant conk off on her own . hard pregnant , she still take the air for miles until she got to a Sir Herbert Beerbohm Tree that Dublin had n’t seen any elephant eat before . The elephant champ the tree until nothing was result but a soapbox , and the next mean solar day went back to her normal feeding pattern . Four days afterward , the elephant delivered a healthy sura .
Dublin thought the behavior was renowned , but did n’t put too much emphasis on it . Even though elephant pregnancy hold up about 22 months , the fact that there were four days between the elephant wipe out the tree and delivering the calf made the connection between them seem weak . Still , when Dublin enquire about the industrial plant , she found that Kenyan women sometimes used it to bring on Labor Department , or to bring on abortion . The plant , boraginaceae , is a relative of Borago officinalis , which was also used by women near the Mediterranean to induce labor . Humans in many part of the earth use the plant , or its cheeseparing relatives , to bring on Labour . This sighting indicates that elephant might be using it for exactly the same determination .
If the elephant are using it , the question is how they got their aesculapian knowledge . Elephants are a matriarchal gild in which former females teach younger ones how to exist , how to witness food , and where to find water . It ’s possible that aesculapian knowledge is also passed from old to jr. generation . It ’s also potential that the behavior is instinctive . When an elephant is late in her pregnancy , she might crave that plant the style humans starve calorie - rich food or vitamin - rich food when they ’re starving .
