The beneficial role of traditional herbal medicines in the treatment of inflammatory skin disorders has been widely reported. Psoriasis is characterized by uncontrolled hyper-proliferation of keratinocytes, disturbed apoptosis, over-secretion of inflammatory cytokines and angiogenic factors. We have developed a novel aqueous polyherbal formulation (SIRB-001) consisting of 3 herbs; Rheum palmatum L., Rehmannia glutinosa Libosch and Lonicera Japonica in the ratio 1:1:3. SIRB-001 has demonstrated efficacious effects in psoriasis patients...

Diabetic kidney disease (DKD) is the leading cause of end-stage kidney disease, and satisfactory therapeutic strategies have not yet been established. The Shen-Yan-Fang-Shuai Formula (SYFSF) is a traditional Chinese formula composed of Astragali radix, Radixangelicae sinensis, Rheum officinale Baill, and four other herbs. It has been widely used as an effective treatment for DKD patients in China. However, little is known about the molecular mechanisms underlying SYFSF's renoprotection. In this study, we compared the protective effect of SYFSF to irbesartan on the histology and renal cells in type 2 DKD rat model and high-glucose (HG) cultured mesangial cells, respectively...

OBJECTIVES: Chrysophanol, also called chrysophanic acid, is a natural anthraquinone compound found in Rheum palmatum. R. palmatum has been used in oriental medicine in ancient East Asia. Microglial cells represent not only the forefront immune defense in the central nervous system but also the most reactive sensors to various threats. However, activated microglia can exert neurotoxic effects via excessive production of cytotoxic molecules and proinflammatory cytokines. Therefore, modulation of microglial cell activation is important for maintaining neuronal function...

The commitment to improve care processes and patient outcomes is a professional mandate for clinicians and is also seen as an operational priority for institutions. Quality improvement now figures in the accreditation of training programs, specialty examinations, and hospital scorecards. Rheumatologists have traditionally focused primarily on quality problems such as guideline adherence; however, improvement goals should also include other aspects of care that are helpful to patients and are professionally rewarding for practitioners...

Chrysophanic acid, or chrysophanol, is an anthraquinone found in Rheum palmatum, which was used in the preparation of oriental medicine in ancient China. The hippocampus plays a major role in controlling the activities of the short- and long-term memory. It is one of the major regions affected by excessive cell death in Alzheimer's disease. Therefore, neuronal cell-death modulation in the hippocampus is important for maintaining neuronal function. We investigated chrysophanol's effects on glutamate-induced hippocampal neuronal cell death...

Rhubarb was grown and used throughout China for thousands of years. It then found its way to St Petersburg where the Romanovs developed a flourishing trade in the plant to the rest of Europe. James Mounsey, a physician to the Tsar, brought back seeds from Russia to Scotland at considerable risk to himself. He passed some of the seeds to Alexander Dick and John Hope. Both these physicians then grew rhubarb at Prestonfield and the Botanic Garden (both in Edinburgh), respectively. Eventually rhubarb, in the form of Gregory's powder, became a common and popular medicine throughout the UK...

Historically, Chinese herbal medicines have been widely used in the treatment of hyperglycemia, but the mechanisms underlying their effectiveness remain largely unknown. Here, we screened a compound library primarily comprised of natural compounds extracted from herbs and marine organisms. The results showed that emodin, a natural compound from Rheum palmatum Linn, inhibited DPP4 activity with an in vitro IC50 of 5.76 µM without inhibiting either DPP8 or DPP9. A docking model revealed that emodin binds to DPP4 protein through Glu205 and Glu206, although with low affinity...

Emodin is a natural anthraquinone derivative isolated from the Rheum palmatum. Recent studies demonstrated that emodin has anti-cancer activity in different kinds of human cancer cell lines. However, the underlying mechanism has not been very well studied. Our previous studies showed chloride channels is an important target of anti-cancer drugs. Therefore, the purpose of this research was aimed to explore the role of chloride channels involving in the anti-cancer activity of emodin. The proliferation, cell cycle arrest and apoptosis of poorly differentiated human nasopharyngeal carcinoma cells (CNE-2Z) and normal nasopharyngeal epithelial cells (NP69-SV40T) were detected by 3-(4,5-dimethylthiazol-2-yl) -2,5-diphenyltetrazolium bromide(MTT)and flow cytometry...
