Hi luvtocamp, Haven't tried it but I would do some research on valarium. Vitamins and food supplements don't fall under the FDA heavy boot, there is no governmental quality control, not clinical trials that obserev vits and food suplement effects on diferent organ systems or potential drug interactions.
The reason why I say this is because Ginsing would be a common homeopath remedy for fatigue, if someone that had thyroid problems they would experience fatigue, The common medical treatment is Thyroid replacement meds "synthroid" but Ginsing counters the effects of this most commonly used thyroid med. So you would actually loose any benefit from both the med and the suplement. The folks at the health food store may rave about some new supplemts abilities and potential for good, but these folks aren't mediclly trained and don't consider possible drug interactions as supplemtns are not considered drugs.
Untill several negative events occur that land people in the ER that can be traced to a drug/supplument interaction, it takes time to get the word out not to mix specifc herbal supplements with specific meds.
Be sure to tell your doc about Vits and herbal suplements as well as any prescribed med or OTC med so the big picture can be looked at without anything homepathic that seems benign being left out of the equation.
On that note, I do belive herbal meds can and are beneficial in many areas of medical treatment, but you need to be sure it's not going to interact with any med or condition you might have. That being said, once cleared by your doc, I do hope it helps in whatever way it's claimed too, although supplements don't have the clinical trials to back that claim. They may do a minimal trial to vouch for it's effectiveness but not the the same double blind trial with a control group and effects on entire organ systems being evaluated that the FDA would require to back any claim made by a pharma manufacturer.

Take care, Dave
