Although the full verdict is still out on Asian ginseng, if the hopes pan out for this herb -- one that has been in use for centuries -- taking it could mean a lot for a man's overall well-being. In fact, the National Center for Complementary and Alternative Medicine states that Asian ginseng is often used to give your immune system a jolt and improve your overall health. Other potential uses include helping your blood pressure, lowering blood glucose and even treating erectile dysfunction [source: National Center for Complementary and Alternative Medicine].
Again, remember to speak with your doctor before incorporating any supplement into your life. Although the National Center for Complementary and Alternative Medicine considers Asian ginseng safe for most people when taken as directed, it does mention possible side effects from long-term use. These include allergic reactions, headaches, stomach concerns and sleep issues. Also, since the herb may lower your blood sugar level, that chat with your doctor is a must [source: National Center for Complementary and Alternative Medicine].
