Rhodiola Rosea L. here means as the root and rhizome of Rhodiola  Rosea L. As rare Chinese medicinal herbs in ancient China, it has  also been used in Tibet medicine.

1. Shape: Perennial herbaceous, with height *5—*5cm.  The root of which is *0—*0cm long, is coarse and  strong,  standing in straight or tilting. Light yellow on the surface of young  root, and brown on the surface of old root. The seed presents  round shape, with length about 2mm. Florescence: April to June;  Fruit period: July to Sep.
2. Gathering: Should be done in Autumn when the leaves turn  withered. Remove broken stem and mud, keep it dry in the  sunshine directly. Not good to gather it in spring, due to the content  of Rosavins in earlier stage of sprouting & blossom is only *0% of that in fruit period.
3 .Distribution:  Most of the Rhodiola Rosea L. plants grow in  hilly area with limestone, & granite, in glacier, grassland or in the  rock of ravine, with altitude of ***0—***0m, of which  distributing widely in Siberia and northern America. Iin China it is  mainly distribute in northern east of China, generally in hillside or  grass slope with altitude of ***0—***0m.
The main chemical composition
There are over *0 kinds of compounds in Rhodiola Rosea L.,  mainly as phenylpropanoids, namely Rosavins including rosavin, rosin and rosarin.

Rosavins:  As one of the effective ingredients in Rhodiola,  Rovasins belong to the kind of phenylethyl glycosides, and the  content is between 0.5—1.5% in Rhodiola rosea.  It’s proved by  study that the Rosavins have pharmaceutical effect for anti-fatigue,  anti-oxidant and stimulating central nervous system , etc.

The major efficacy
1. Improving immunity and anti-cancer activity
The immune system in two ways by Rosavins: First, by specific  direct stimulation of immune defense.  Rhodiola Rosea L. extract  normalizes the immune system by improving T-cell immunity.  It has been shown to increase the body’s resistance to toxins that  may accumulate during infection development.  Second, by making  the body less susceptible to stress. Rhodiola Rosea L. extract can  also enhance B cell immunity by preventing the suppression of B  cell immunity. The scientists from Russia found out that *9% of the  tumor growing in big rat with experiment were inhibited and *0%  of the tumor transferring in big rat were reduced by taking Rhodiola  Rosea L. extract orally. It’s helpful to improve urinary tissue and  immunity for those who suffer from bladder cancer. In all the  experiments to other kinds of cancer, including gland carcinoma  (such as breast cancer, etc.) and tumor in lung, Rhodiola Rosea L.  extract appears great rising in survival ratio.
2. Anti-depression
Rosavins enhances the transport of serotonin precursors,  tryptophan and *-hydroxytryptophan into the brain.  Unbalanced serotonin has been linked to various abnormal mental  states such as clinical depression. Rosavins has been used by  Russian scientists alone or in combination with anti-depressants  to boost one’s mental state.  In one experiment to **8 patients  who take Rosavins, *5% of them more or less reduce or remove  depression effectively.
3. Cardio-protective Activity
Rosavins t has been shown to moderate stress-induced damage  and dysfunction in cardiovascular tissues.  Treatment with it  prevents the decrease in cardiac contractile force secondary to  environmental stress in the form of acute cooling and contributes to  stable contractility.  Pretreatment with Rhodiola Rosea extract  appears to create a beneficial adaptive response in this type of  stress.
4. Anti-oxidant Activity
Rhodiola has potent antioxidant properties.  By limiting the adverse  effects of free radical damage, it’s able to combat diseases  associated with aging.
