I heard that "Ginseng" is considered as gold or more valuable in some places!
Anyway, ginseng has many health benefits as you have mentioned here. One thing, the pharmaceutical agents promote about ginseng is that it increases the sexual power in male. I haven't tested in me :P
In Oman, we have multiple vitamin type medicines, which also contain a portion of ginseng extract. The price of those vitamins are higher than the non-ginseng vitamins.
Yeah ginseng have many health benefit :)
