The root of the ginger plant is well known for its use as a cooking spice in China, Japan and Southern Asia. It was described by the thirteenth century(26)explorer Marco Polo in his writings. Ginger’s use is even discussed in the "Talmud", the book that explains Jewish(27)religious laws. The ginger plant has yellow-green flowers with(28)purple edges and yellow spots. Its root is used to(29)add taste to several kinds of food including soups and(30)cookies. It also is used to make tea.
    Recently scientists have been studying the ginger root for possible use as a medicine. Ginger contains several(31)chemical substances and scientists in Denmark did a study three years ago that showed ginger can reduce the threat of heart attack and(32)stroke. During the weeklong study, women were given 70 grams of uncooked(33)onion each day or 5 grams of uncooked ginger.
    American researchers at Louisiana State Medical Center tested gingers for possible use in preventing(34)motion-sickness which is a condition that affects many people who travel by plane or boat. The study showed that ginger does not work to prevent that kind of stomach sickness, but a study by British researchers found that ginger does work to prevent stomach sickness during(35)surgery.
