Ginseng (Panax ginseng (also known as Asian ginseng, Korean ginseng); American ginseng (Panax quinquefolius)) — Uses, Dosage, Side Effects & Safety

Drug class: Herbal supplement; Adaptogen

Overview

Ginseng is a popular herbal supplement derived from the roots of plants in the Panax genus, most commonly Panax ginseng (Asian or Korean ginseng) and Panax quinquefolius (American ginseng). It is traditionally used to enhance energy, improve mental and physical performance, and support overall well-being. Ginseng contains active compounds called ginsenosides, which are believed to help the body adapt to stress, boost immune function, and may have antioxidant effects. Some studies suggest it may help with fatigue, cognitive function, and blood sugar control, but evidence is mixed and more research is needed. Key points for patients: Ginseng is available over the counter in various forms. It is generally considered safe for short-term use, but it can interact with other medications and may not be suitable for everyone. Always consult your healthcare provider before starting ginseng, especially if you have chronic health conditions or take prescription medications.
