Pharmacokinetic and pharmacodynamic study of interaction of Rhodiola rosea SHR-5 extract with warfarin and theophylline in rats

Significant pharmacokinetic/pharmacodynamic interactions between various herbal products and drugs being substrates of cytochrome P450 have recently been reported. The aim of this study was to determine whether Rhodiola rosea SHR-5 extract interacts with warfarin and theophylline when administered concomitantly. Thus, concomitant treatment of rats with theophylline and SHR-5 did not give rise to significant effects on the pharmacokinetics of theophylline. Simultaneous administration of SHR-5 and warfarin did not alter significantly the pharmacokinetics or the anticoagulant activity of warfarin. It is concluded that SHR-5 might be of value in the treatment of patients with mild or moderate depression, and that its interaction with co-administered drugs is likely to be negligible.     

The Effects of Rhodiola rosea L. Extract on Anxiety,Stress, Cognition and Other Mood Symptoms

This trial evaluated the impact of a Rhodiola rosea L. extract on self‐reported anxiety, stress, cognition, and other mood symptoms. Eighty mildly anxious participants were randomized into two different groups of either Rhodiola rosea L (2 × 200 mg dose Vitano®, 1 tablet taken before breakfast and 1tablet before lunch) or a control condition (no treatment). Self‐report measures and cognitive tests were completed at four testing sessions over a period of 14 days. Relative to the controls, the experimental group demonstrated a significant reduction in self‐reported, anxiety, stress, anger, confusion and depression at 14 days and a significant improvements in total mood. No relevant differences in cognitive performance between the groups were observed. Rhodiola rosea L (Vitano®) presented a favourable safety tolerability profile. Although this was a non‐placebo controlled trial, it is unlikely that the findings were the result of placebo effects as changes appeared gradual and were specific to certain psychological measures. However, we cannot determine a causal relationship; further investigations are recommended to support the effects of Rhodiola rosea L. extract on stress related symptoms.

In vivo Th1 and Th2 cytokine modulation effects of Rhodiola rosea standardised solution and its major constituent, salidroside

Although Rhodiola rosea (L.) is used widely and disseminated in Oriental medicine, its in vivo effects on cytokine modulation remain unclear. Among the biologically active components of Rhodiola rosea, salidroside was suggested to be the most active compound. The objectives of this study were to assess the toxicity and cytokine modulation effects of Rhodiola rosea standardised solution (RRSS) and salidroside. Quantitative high pressure liquid chromatography (HPLC) analysis determined the content of salidroside in RRSS to be 4.39% (w/v). Groups of Balb/c mice were fed daily with different doses of RRSS or salidroside, with CAPE or distilled water used as positive and negative controls, respectively. The acute and subacute toxicity tests did not reveal weight differences, pathological changes, or abnormalities in liver or kidney function indices among the treated groups. Ovalbumin‐primed mouse cytokine assays demonstrated that both T helper (Th1) (IL‐2 and IFN‐γ) and Th2 (IL‐4 and IL‐10) cytokines were significantly increased by feeding with RRSS in a dose‐ and time‐dependent manner (p < 0.05). Moreover, the cytokine modulation effects of salidroside were less prominent than that of RRSS treatment and not dose‐dependent. These findings suggest that increased secretion of both Th1‐ and Th2‐pattern cytokines can be achieved with RRSS and salidroside treatment. Copyright © 2011 John Wiley & Sons, Ltd.

Rhodiola rosea extract protects human cortical neurons against glutamate and hydrogen peroxide-induced cell death through reduction in the accumulation of intracellular calcium

The aim of this study was to investigate the neuroprotective effects of a titolated extract from Rhodiola rosea L. (RrE) and of salidroside (Sa), one of the major biologically active compounds extracted from this medicinal plant, against oxidative stressor hydrogen peroxide (H₂O₂) and glutamate (GLU)‐induced cell apoptosis in a human cortical cell line (HCN 1‐A) maintained in culture. The results obtained indicate that exposure of differentiated HCN 1‐A neurons to GLU or H₂O₂ resulted in concentration‐dependent cell death. A 24 h pre‐treatment with RrE significantly increased cell survival and significantly prevented the plasma membrane damage and the morphological disruption caused by GLU or H₂O₂, indicating that neurons treated with RrE were protected from the neurotoxicity induced by the oxidative stressor used. In addition, RrE significantly reduced H₂O₂ or GLU‐induced elevation of intracellular free Ca²⁺ concentration. The results obtained have also shown that Sa caused similar effects in all experimental models used; however, the potency of the action was lower than that of the extract containing corresponding quantities of Sa. These findings indicate that RrE has a neuroprotective effect in cortical neurons and suggest that the antioxidant activity of the RrE, due to the structural features of the synergic active principles they contain, may be responsible for its ability to stabilize cellular Ca²⁺ homeostasis.

Adaptogenic and central nervous system effects of single doses of 3% rosavin and 1% salidroside Rhodiola rosea L. extract in mice

Rhodiola rosea L., or 'golden root', is a popular plant in traditional medicine in Eastern Europe and Asia, with a reputation for improving depression, enhancing work performance, eliminating fatigue and treating symptoms of asthenia subsequent to intense physical and psychological stress. Due to these therapeutic properties, R. rosea is considered to be one of the most active adaptogenic drugs. To confirm and extend results obtained in the few preclinical and clinical studies available in English language journals, the purpose of the present study was to re-investigate the effects produced by a single oral administration of an R. rosea hydroalcohol extract (containing 3% rosavin and 1% salidroside) on the central nervous system in mice. The extract was tested on antidepressant, adaptogenic, anxiolytic, nociceptive and locomotor activities at doses of 10, 15 and 20 mg/kg, using predictive behavioural tests and animal models. The results show that this R. rosea extract significantly, but not dose-dependently, induced antidepressant-like, adaptogenic, anxiolytic-like and stimulating effects in mice. This study thus provides evidence of the efficacy of R. rosea extracts after a single administration, and confirms many preclinical and clinical studies indicating the adaptogenic and stimulating effects of such R. rosea extracts. Moreover, antidepressant-like and anxiolytic-like activities of R. rosea were shown in mice for the first time.
