 Pharmacological actions: ①.adaptogenic actions and anti-stress; ②.aid muscle recovery and increase physical work capacity; ③.enhances memorisation and relieve neurodegenerative diseases; ④.immune system protection; ⑤.relieve depression; ⑥.cardioprotective effect and relieve cardiac problems; ⑦.anti-carcinogenic effect and prevent cancer; ⑧.antioxidant activity. ⑨.antibacterial effects, ⑩.other activities and findings.

 Adaptogenic actions and anti-stress: Rhodiola rosea has long been known as a potent adaptogen. Adaptogens increase the body's non-specific resistance and normalize the functions of the body, consuming adaptogens generates a degree of generalized adaptation or non-specific resistance that allows our physiology to handle the stressful situation in a more resourceful manner, adaptogens work by increasing the ability of cells to manufacture and use cell fuel more efficiently. Some common claimed adaptogenic properties of Rhodiola rosea are to relieve asthenic conditions including a decline in work performance, sleep disturbances, poor appetite, irritability, hypertension, headaches, and fatigue, developing subsequent to intense physical or intellectual strain, influenza, other viral exposures, and other ailments.

 Rhodiola Rosea component:salidroside Aid muscle recovery:Rhodiola rosea could shorten recovery time after prolonged workouts, it stimulates muscle energy status, glycogen synthesis in muscles and liver, muscle protein synthesis and anabolic activity.

 Increase physical work capacity:Rhodiola rosea increased physical work capacity and dramatically shortened the recovery time between bouts of high-intensity exercise. Endurance is the capacity to maintain work despite fatigue.

 Enhances memorisation and improves learning: Rhodiola rosea enhances memorization and concentration ability over prolonged periods.

 Relieve neurodegenerative diseases: Rhodiola rosea has potent neuroprotective effects, it has beneficial effects for the treatment of Alzheimer's disease and other neurodegenerative diseases.

 Rhodiola Rosea component:rosin Immune system protection: Rhodiola stimulates and protects the immune system. It protects the immune system by making a person less susceptible to stress, it can enhance B cell immunity.

 Anti-carcinogenic effect and prevent cancer: Rhodiola increases anti-tumor activity by increasing the body's resistance to toxins, its identified anti-oxidant compounds have significant free-radical scavenging activity, it can significantly increase survival rate in other experiments with various types of cancer, including adenocarcinomas.

 Rhodiola Rosea component:rosavin Relieve depression: Rhodiola could enhance the transport of serotonin precursors into the brain, the herb has been used to boost one's mental state. Rhodiola rosea alleviated fatigue, irritability, distractibility, headache, weakness, and other vegetative symptoms.

 Cardioprotective effect and relief of cardiac problems: Rhodiola is effective for cardiac problems caused or aggravated by stress, it protects the heart in various ways.

 Rhodiola Rosea component:rosarin Antioxidant activity: Rhodiola rosea protect the nervous system from oxidative damage by free radicals. Studies attribute its antioxidant activity to phenolic compounds, polysaccharide, and oligomeric proanthocyanidins.

 Its antioxidant activity helps protect the skin, it is useful in minimizing the adverse skin responses associated with such oxidant species.

 Its antioxidant activity helps prevent atherosclerosis, the oligomeric proanthocyanidins have an anti-atherosclerosis function.

 Rhodiola Rosea component:tyrosol Antibacterial effects: studies found that dried Rhodiola rosea root has strong antibacterial effects against Staphylococcus strains.

 Other activities: studies found Rhodiola rosea and its preparations has other useful properties and activities, including significant anti-inflammatory activity and analgesic activity, radioprotection activity, alpha-glucosidase inhibitory activities, angiotensin-converting enzyme (ACE) inhibitory activity, indicating its uses in the management of type II diabetes and hypertension.

 Medicinal efficacy: Traditional folk medicine used Rhodiola rosea as an adaptogen to increase physical endurance, increase the resistance to different stress conditions, enhance work performance and productivity, and longevity, prevent high altitude sickness, stimulate the nervous system, relieve fatigue, and as an antidepressant to relieve depression, headaches, anemia and sleep difficulties, impotence, gastrointestinal ailments, infections, and nervous system disorders, extenuate anxiety, cognitive dysfunction, etc.

 Except for the traditional uses, according to modern findings, Rhodiola rosea, and its preparations could be used to prevent cancer and protects the immune system, protects the heart from harmful blood lipids, eliminate heart disease risk factors including raised blood pressure, cholesterol level and potassium level; its phenolic components (salidroside, rosavins, and p-tyrosol) can be used for neuroprotection to prevent and relieve neurodegenerative diseases including Alzheimer's disease, used to enhance learning and memory function including memorization and concentration ability, protect skin keratinocytes, its oligomeric proanthocyanidins could be used to prevent atherosclerosis, its ethanol or water extracts and phenolic contents can be used for hypertension and type II diabetes, to relieve pain and inflammation, etc.
