The reason we don't discuss brands here is most of us collect wild ginseng and/or grow wild simulated ginseng.
Below is the brand that I take myself...
You got to get out and walk the hills and hollows and look hard to find that brand
I break off a few root hairs or slice off a piece of root and have just a little in my green tea or coffee 3-4 times a week or I will just eat it dry, or fresh and green in harvest season.
The main benefits I have noticed is no sickness (colds, flue, sinus, allergy, strep throat, etc) just never happens anymore.
You can shop around online (ebay) for example, and buy wild root. You might even be able to buy it from some dealers that buy/sell it.
Good Luck !
