IPC: A23L21/25
Filed: 2015-07-06
Abstract: The present invention relates to a ginkgo leaf pill. More specifically, the present invention relates to a ginkgo leaf pill prepared by mixing ginkgo leaves along with nuts after detoxification of ginkgo leaves. With regard to the administration of pills, liquid herbal medicine is hard to store, easy to spill, and highly spoilable, thereby causing inconvenience. Instead, by producing the herbal medicine in a form of pill, it is possible to minimize odor production while being convenient to eat and store. Although ginkgo leaves are enriched in nutrition and contain various components excellent in preventing various adult diseases, ginkgo leaves, however, contain 4-methoxypyridoxine (MPX), a toxic component innoxuous to human body, and also produce stinking smells when taken. To this end, the ginkgo leaf pill is produced by grinding ginkgo leaves, nuts, licorice, and ginger, and then processing the ground ingredients into a pill form. According to the present invention, the ginkgo leaf pill prevents adult diseases and promotes national health.
