So much has been said about this plant I can't type as fast and as much it is touted to do so I will hit on the main points of this root herb.
It will help purify the blood as well as improve on brain functions
I highly suggest Siberian Ginseng, it more potent, and has the ability to promote good general health.
Suggested Dosage:
1-3 tablets per day, it is your choice.
