Rhodiola Rosea is by far my favourite herb. Hardly any other herb comes close to combining as many versatile properties. It is mostly known to boost ATP/phosphocreatine synthesis, thereby delivering significant benefits in terms of strength and endurance. Beyond this, it possesses other cool benefits such as exerting significant authentic adaptogenic effects (via modulation of hypothalamic serotonin, norepinephrine, beta-endorphin, and opioid peptide levels that change in response to stress); treatment of thyroid dysfunction and adrenal fatigue, without causing hyperfunction; boosting the effectiveness of neurotransmitters such as serotonin, dopamine, and norepinephrine in the brain; treatment of arrhythmia and tachycardia; boosting cognition, concentration, and mental performance; inhibition of C-reactive proteins (an inflammatory compound) and creatine kinase (a measure of muscle damage); promoting healthy sleep and recovery; modulation of anorexia; reduction of hyperglycemia and management of diabetic complications; treatment of infertility in women (even when standard fertility-enhancing drugs fail!) and irregular menstruation; adjustment in sexual dysfunction in men (erectile dysfunction and premature ejaculation) and women; reduction of the toxicity of anti-cancer drugs and enhancement of their effectiveness; prized anti-oxidant effects. All that with few, if any, side effects, even at supra-physiological doses! There is no drug that can even come close to delivering half of these benefits without substantial side effects, even within recommended doses!
