Is American ginseng (Panax Quinquefolius) safe to take on a daily basis if one tends to be a bit (kidney) yin deficient? I'm referring to a daily dose of a couple of grams (dried) steeped in hot water 2-3 times then eaten.

I need a relatively inexpensive general tonic. I'm in OK shape overall, but I have tendency towards qi deficiency. I practice taiji somewhat regularly. Should I combine the ginseng with some other herbs to balance things out?
