Rhodiola (Rhodiola rosea)

Rhodiola-herb.jpg

Rhodiola Overview:

Rhodiola was made famous by some earlier research done by Russian scientists in the 1960's. Although a lot of this research still hasn't been released to the public, there has been a lot fo new studies put forward to make up for this loss.

Rhodiola is well revered as an adaptogen for treating fatigue, cognitive decline, depression, and for athletic enhancement. It's considered to be a mild stimulant, though it doesn't produce the "wired" feeling many other stimulants produce. It increases energy levels and makes us more tolerant to stressful situations.

Although there is still a lot of research lacking, we know that Rhodiola can reduce cortisol levels in the body after exposure to stress, however, the details on how this interaction exists is still not well understood. There is also a great deal of confusion around which chemicals are active in the herb, some studies showing the rosavins, others tyrosol and the rhodiolasides. A result from this confusion and dispute is a wide range of differentiation between the "standardised doses" of this herb. Each manufacturer tends to have a preference for one chemical group over the other in their products.
