Possible, but the science behind the pill is pretty interesting.
It is basically just the 2 most active ingrediants in Ginsing, isolated and concentrated, and put into a capsule.
The chinese have used it for ~2000-5000 years. I am guessing that use started when it did a better job then any other plant or remedy in their environment. And they are still using it! That is a pretty long trial run...
