Hi there

Well I suppose it is possible.  However, I would strongly urge you to discuss this with your doctor before you start any weaning of medications.  You never want to go cold turkey and just because this is a natural substance does not mean there won't be interactions with your other meds.  Many doctors these days know about supplements so it is best to ask ahead of time.

On a personal note, I do have Rohdiola Rosea in my cupboard.  I tried it for a short time and my thoughts were that it increased my energy and gave me a little zip in my zippyitydoodah.  It was mildly helpful for me.  I don't think it could ever replace my SAM-e that I am taking regularly, however.

It is good to research the supplements and that does get difficult because most links will take you to sites which sell the product. 

Here is the wise geek site with information about rhodiola rosea to start.

And here is a PubMed abstract which gives us this information:

"Rhodiola rosea is a popular plant in traditional medical systems in Eastern Europe and Asian with a reputation for stimulating the nervous system, decreasing depression, enhancing work performance, eliminating fatigue, and preventing high altitude sickness. Rhodiola rosea has been categorized as an adaptogen by Russian researchers due to its observed ability to increase resistance to a variety of chemical, biological, and physical stressors. Its claimed benefits include antidepressant, anticancer, cardioprotective, and central nervous system enhancement. Research also indicates great utility in asthenic conditions (decline in work performance, sleep difficulties, poor appetite, irritability, hypertension, headaches, and fatigue) developing subsequent to intense physical or intellectual strain. The adaptogenic, cardiopulmonary protective, and central nervous system activities of Rhodiola rosea have been attributed primarily to its ability to influence levels and activity of monoamines and opioid peptides such as beta-endorphins."

If you look...there is more research on this supplement as well on the Pub.Med.gov site.  It seems that primarily Rhodiola Rosea is an "endurance" supplement...helps to keep your energy up.

I hope this helps and if you do decide to take it (talk to your doctor first!) let us know how it works out for you.
