Background: Herbal supplementation has been used by diabetic patients, unfortunately it has regulatory, safety, and efficacy concerns. Objective: This review was conducted to determine the best evidence in terms of the identified active substance, mechanism of action, pre-clinical and clinical studies of commonly used local herbal preparations. Methods: This is a qualitative review of both local and international published medical literature to identify and summarize information on the use of herbal supplementation in diabetes. Results: After the initial review, the authors identified thirteen herbal preparations that have been investigated for its anti-diabetic properties. Six have extensive studies including randomized controlled trials but cinnamon and fenugreek seed are not readily available locally. Their detailed review eventually focused on four locally available herbal preparations i.e. bitter melon, turmeric, aloe vera and banaba. They decrease glucose absorption and gluconeogenesis, improve glucose utilization and insulin production. Unlike conventional anti-diabetics, herbal preparations also have favorable effect on lipid metabolism and anti-oxidant effect. Bitter melon seems to be the best herbal preparation. But human studies of bitter melon showed it is inferior to conventional anti-diabetic drugs in terms of its anti-diabetic effect but better in terms of its effect on lipid metabolism and anti-oxidant properties. Turmeric, aloe vera and banaba have also been shown to have anti-diabetic effects. Conclusion In summary, herbal preparation may have multiple beneficial effect for patients with diabetes. Use of combined preparations can produce complementation of the effects and may be a promising approach to the use of herbal supplementation as treatment standard among patients with diabetes.

Antioxidant-the word itself is magic. Using the antioxidant concept as a spearhead in proposed mechanisms for staving off so-called "free-radical" reactions, the rush is on to mine claims for the latest and most effective combination of free-radical scavenging compounds. We must acknowledge that such "radicals" have definitively been shown to damage all biochemical components such as DNA/RNA, carbohydrates, unsaturated lipids, proteins, and micronutrients such as carotenoids (alpha and beta carotene, lycopene), vitamins A, B6, B12, and folate. Defense strategies against such aggressive radical species include enzymes, antioxidants that occur naturally in the body (glutathione, uric acid, ubiquinol-10, and others) and radical scavenging nutrients, such as vitamins A, C, and E, and carotenoids. This paper will present a brief discussion of some well- and little-known herbs that may add to the optimization of antioxidant status and therefore offer added preventive values for overall health. It is important to state at the outset that antioxidants vary widely in their free-radical quenching effects and each may be individually attracted to specific cell sites. Further evidence of the specialized nature of the carotenoids is demonstrated by the appearance of two carotenoids in the macula region of the retina where beta-carotene is totally absent.

Background: In the past musculoskeletal complaints were treated with topical preparations from medicinal plants until the advent of NSAIDs. However, because of the side effects of NSAIDs, interest has increased on going back to the use of topical traditional herbal medicines in patients with musculoskeletal pain. Objective: This review was conducted to identify the active substance, its mechanism of action, pre-clinical and clinical studies and propose a topical herbal formulation balancing its analgesic and anti-inflammatory effect with skin care effect among patients with various somatic pain conditions. Methods: This is a qualitative review of both local and international published medical literature to identify and summarize information on the use of topical herbal preparation for the treatment of musculo-skeletal pain. Results: After the initial review, the authors identified six herbal preparations that have been investigated for its analgesic and anti-inflammatory properties in clinical trials. They eventually arrived at a consensus to consider the final combination of ginger, capsaicin, peppermint and virgin coconut oil. Gingerol, a naturally occurring plant phenol, is one of the major components of ginger known to have diverse pharmacologic effects including anti-oxidant, anti-apoptotic, and anti-inflammatory activities in vitro and in vivo. Capsaicin is a highly selective agonist for the transient receptor potential vanilloid 1 receptor expressed in nociceptive sensory nerves. The mechanisms underlying capsaicin-induced analgesia likely involve reversible ablation of nociceptor terminals. Local application of peppermint oil generates a long-lasting cooling effect on the skin and result to muscle relaxation. Ginger, capsicum and peppermint have been shown in clinical trials to relieve musculoskeletal pain and inflammation. Virgin coconut oil on the other hand has no analgesic effect but has been shown in some studies to be favorable for skin conditions and facilitate skin penetration of some substances. Conclusion Using combined preparation may have the advantage of complementation of its effect i.e. analgesic and anti-inflammatory effect of ginger, warm sensation of capsicum and the cold sensation of peppermint.

Plants synthesize certain phytoconstituents for their protection, which, because they are not of primary need, are known as secondary metabolites. These secondary metabolites of plants, have often been found to have medicinal uses for human beings. One such gymnosperm having secondary metabolites of medicinal potential for humans is Taxus wallichiana (Himalayan yew). Besides being the source of taxol, this plant has been investigated for its essential oil, diterpenoids, lignans, steroids, sterols and biflavonoids. Traditionally, it is used to treat disorders of the digestive, respiratory, nervous and skeletal systems. Although pharmacologically underexplored, it has been used for antiepileptic, anti-inflammatory, anticancer, antipyretic, analgesic, immunomodulatory and antimicrobial activities. The present review compiles traditional uses, phytochemical constituents (specifically the secondary metabolites) pharmacological activities and the toxicity of T. wallichiana.

This study aims to explore the evaluation model for the proficiency testing of heavy metal and harmful element residues in pharmaceuticals,and to provide reference for the proficiency testing program and proficiency testing result in the field of residue analysis. The proficiency test result of cadmium determination in honeysuckle as an example. The algorithm A,NIQR,and Horwitz function are used to calculate the assigned value and the standard deviation. Z was obtained at the same time. If | Z | ≤2,the result is satisfactory. If 2< | Z | <3,the result is questionable. If | Z | ≥3,the result is unsatisfactory. In addition,the median value is the assigned value,and deviation(D%) is used. If D% is not more than 16%,the result is satisfactory; if D% is more than 16%,the result is unsatisfactory. After analysis,in the results of questionable or dissatisfied laboratories calculated by algorithm A and NIQR,the deviation error of some data is within the scope of the standard. In the results of the satisfactory laboratory evaluated by the Horwitz function,some data deviation errors far exceed the standard range. The evaluation result of the D% meets the requirements. According to heavy metal and harmful element trace analysis methods,this study is the first to apply D% to the evaluation of the detection ability of heavy metals and harmful elements in pharmaceuticals. This method makes the evaluation result more reasonable,and has important reference significance for the evaluation of other proficiency test results.

This research preliminarily discusses the relations of Dendrobium system growth through chloroplast gene rbcL, matK and the nuclear genome ITS2. The DNA barcoding universal sequence for authentication of the Dendrobium medical plants was slected and the possibility concerning utilizing the DNA barcoding to distinguish the D. huoshanenseand its adulterants was analyzed. Using the universal primer pair of ITS2, rbcL and matK, series of extended sequencing in the Dendrobium were conducted. Meanwhile, considering the different index about amplification and sequencing success rate of each sequence, the intraspecific and interspecific aberrance, the employment of BioEdit and MEGA 5.0 software were applied to establish the systematic tree of the NJ molecular and evaluate the diversified authentication capability of various sequences. The consequence demonstrates that the sequence of ITS2 is not only the largest one both in the intraspecific and interspecific aberrance of the Dendrobium but also has obvious barcoding gap. Considering the few overlap between the intraspecific and interspecific aberrance and the highest percentage regarding the formation of unilateral branch in diverse Dendrobium which have different ITS2 sequences, it can differentiate the species of Dendrobium. Furthermore, due to the inferior success rate of the rbcL and thematK and the lower reliability of NJ systematic tree, the percentage of the unilateral species which are generated by the systematic tree of rbcL and matK sequences is deficient. Therefore, the sequence of ITS2 can serves as DNA barcoding to distinguish the D. huoshanense, the D. moniliform and the D. officinale.

PURPOSE: Herbal preparations have long been used for medical purposes by traditional cultures, and their use is increasing in modern societies. However, many herbal agents produce specific cardiovascular toxicities in humans. We performed this study in order to investigate the clinical characteristics of the cardiac toxicities associated with herbal remedies. METHODS: We conducted a retrospective study of 45 patients (mean age 57+/-10 years) who presented with cardiotoxicity between January 2007 and May 2011 due to ingestion of herbal remedy substances. Patients were identified as suffering cardiotoxicity if they presented with chest pain, EKG abnormality, and elevation of cardiac enzyme. RESULTS: Of the 45 total cases, 17 included hemodynamic instability (37.8%), 7 with increasing cardiac enzyme (15.6%), 2 with cardiac arrest (4.4%) and one case of mortality (2.2%). The cardiotoxic herb group that demonstrated the worst clinical course was Ranunculaceae. CONCLUSIONS: In our study results, 57.6% of the herbal intoxication patients demonstrated the effects of cardiotoxicity. Thus, we recommend careful monitoring of herbal intoxication patients.

Recently the use of herbal preparations as remedies for various medical conditions, has been rapidly increasing in Korea. In our previous study, 38.9% of patients with chronic liver disease were found to use some sorts of herbal preparations. They believe herbal preparations are safe although the ingredients has never been rigorously substantiated. Toxicities of certain herbal preparations are caused by their contaminants and adulterated ingredients or concurrently used conventional drugs rather than specific components of the herbal preparations. Furthermore, in most instances, multiple herbal ingredients are used by the prescribers of oriental medicine. All of these conditions frequently impose diagnostic difficulties. There are myriads of plant-derived hepatotoxic substances which may or may not cause liver injury in individuals. The severity of liver injury depends largely on the toxicity of the substance, the amount of exposure and the individual's susceptibility. These toxic substances cause liver injury not only through the mechanism of intrinsic hepatotoxicity but also through the idiosyncrasy as in conventional drug-induced injury. Therefore, theoretically, it is possible to apply pre-existing CAMs (Causality Assessment Methods) to the assessment of causality in cases with diagnostic difficulties.
