Ginseng Extract is extracted from the root and leaf of Panax ginseng C. A. Mey, which is the specie of slow-growing perennial plants with fleshy roots, belonging to the genus Panax of the family Araliaceae. Ginseng is found only in the northern hemisphere, in eastern Asia (mostly Korea, northeastern China, Bhutan and eastern Siberia), typically in cooler climates.

UMMC warns that women who are pregnant, breastfeeding or at high risk for breast cancer should avoid ginseng. The extract may negatively interact with diabetes medications, blood thinners, antidepressants and antipyschotic medications. In addition, people on certain types of ADHD medications, such as amphetamines or methylphenidate, should avoid ginseng because it may enhance the stimulant effect of these drugs and increase their side effects.
