Ginseng Roots

Is ginseng root is excellent for increasing sexual verility in men?
I recently visited Korea, and people believe there is a root of ginseng for both sexual potency in men. I also saw that the ginseng products (tea, candy, drinks) are all very expensive. It seems to me that it's just superstition, a famous Korean money-hungry used as an excuse to sell stuff handy. Anyone have any facts on the real quality of ginseng (if any)?
Ginsing not have to factor that and the best comes from Korea. It contains: Panaquilon (internal secretion stimulants) Panaxin (the central organ, the heart and blood vessels stimulant) Panacene (Stimulants medulla and central nervous system relaxation) and Panaxic acid (promotes metablosim and relaxes heart and artery movements) Plus: Amylase and phenolase (Enzyme), vitamin B1 and B2, schingenin and saponins. Some herbal experts feel it is best when taken with gotu kola (fo-ti-Tieng). There's something there, but it is difficult to separate fact from fantasy
