Orientals ascribe to motherwort the power of prolonged life. According to Chinese legend, an emperor who at age seven assumed the throne was alarmed by predictions that he would not live to double that age. After an extensive search for a remedy to prolong life, he chose a brew made from motherwort. Drinking this every day, he lived past age 70. Another legend tells of a youth banished for a minor crime to a valley where the only water supply was in contact with a large amount of motherwort plants. Because he drank this water daily, the youth lived three centuries.
This herb probably derived its name from the fact that it has been used medicinally to prevent miscarriage.
