ginseng
n. the root of various plants of the genus Panax, valued for its medicinal properties, particularly in Asian cultures. It has a reputation as an aphrodisiac and is also used to enhance overall physical and mental well-being, boost energy, and relieve stress, but there is little clinical evidence supporting its effectiveness for any of these purposes. Some studies, however, have suggested that ginseng may help regulate blood glucose levels, which has prompted investigation of its potential use as a treatment for diabetes, and may improve immune function. Side effects of ginseng use are infrequent but may include nausea and vomiting, diarrhea, insomnia, headaches, nosebleeds, and blood pressure abnormalities. Additionally, ginseng may interact with anticoagulants, caffeine, monoamine oxidase inhibitors, and oral hypoglycemics.
