Abstract
Corynoxeine, a natural active alkaloid found in Genus Uncaria, has been reported to have anti-depressant effects. In this study, a sensitive and efficient ultra-high performance liquid chromatography tandem mass spectrometry method for quantifying corynoxeine in rat plasma and tissues was established, validated and applied to investigate the pharmacokinetics and tissue distribution differences between normal rats and chronic unpredictable mild stress (CUMS)-induced depression model rats following oral administration. All bio-samples were prepared by methanol protein precipitation method with theophylline as internal standard (IS). Chromatographic separation was conducted on an Agilent ZORBAX Eclipse Plus C18 column using mobile phase A (acetonitrile) and B (0.1% formic acid in water) in gradient elution mode with a flow rate of 0.3 mL/min. Mass spectrometric detection was performed in multiple-reaction monitoring mode with positive electrospray ionization source. The transitions of m/z 383.0→160.2 for corynoxeine and m/z 181.1→124.0 for IS were chosen for quantification. The method showed good linearity, stability, accuracy, precision, recovery, and non-significant matrix effect, which were within the acceptable ranges. The pharmacokinetic results revealed that the absorption and bioavailability of corynoxeine in depression rats decreased compared to normal rats. The tissue distribution of corynoxeine trended to be mostly in the intestine and stomach and the distribution of this compound in intestine tissue of depression rats was significantly increased compared to the normal rats. The pharmacokinetics and tissue distribution profiles of corynoxeine were altered in CUMS-induced depression rats compared to normal rats and these experimental findings could provide beneficial information to the mechanism research and clinical applications of corynoxeine.

Abstract
The Labisia pumila (LP) is a traditional plant that is locally known as Kacip Fatimah, Selusuh Fatimah, or Pokok Ringgang by the Malaysian indigenous people. It is believed to facilitate their childbirth, treating their postchild birth and menstrual irregularities. The water extract of LP has shown to contain bioactive compounds such as flavonoids, ascorbic acid, β-carotene, anthocyanin, and phenolic acid, which contribute extensive antioxidant, anti-inflammatory, antimicrobial, and antifungal. The LP ethanolic extract exhibits significant estrogenic effects on human endomentrial adenocarcinoma cell in estrogen-free basal medium and promoting an increase in secretion of alkaline phosphate. Water based has been used for many generations, and studies had reported that it could displace in binding the antibodies and increase the estradiol production making it similar to esterone and estradiol hormone. LP extract poses a potential and beneficial aspect in medical and cosmeceutical applications. This is mainly due to its phytoestrogen properties of the LP. However, there is a specific functionality in the application of LP extract, due to specific functional group in phytoconstituent of LP. Apart from that, the extraction solvent is important in preparing the LP extract as it poses some significant and mild side effects towards consuming the LP extracts. The current situation of women reproductive disease such as postmenopausal syndrome and polycystic ovary syndrome is increasing. Thus, it is important to find ways in alternative treatment for women reproductive disease that is less costly and low side effects. In conclusion, these studies proven that LP has the potential to be an alternative way in treating female reproductive related diseases such as in postmenopausal and polysystic ovarian syndrome women.

Abstract
At present, cardiovascular disease (CVD) remains the leading cause of morbidity and mortality worldwide, and global trends suggest that this panorama will persist or worsen in the near future. Thus, optimization of treatment strategies and the introduction of novel therapeutic alternatives for CVD represent key objectives in contemporary biomedical research. In recent years, phytotherapy-defined as the therapeutic use of whole or minimally modified plant components-has ignited large scientific interest, with a resurgence of abundant investigation on a wide array of medicinal herbs (MH) for CVD and other conditions. Numerous MH have been observed to intervene in the pathophysiology of CVD via a myriad of molecular mechanisms, including antiinflammatory, anti-oxidant, and other beneficial properties, which translate into the amelioration of three essential aspects of the pathogenesis of CVD: Dyslipidemia, atherosclerosis, and hypertension. Although the preclinical data in this scenario is very rich, the true clinical impact of MH and their purported mechanisms of action is less clear, as large-scale robust research in this regard is in relatively early stages and faces important methodological challenges. This review offers a comprehensive look at the most prominent preclinical and clinical evidence currently available concerning the use of MH in the treatment of CVD from a bench-to-bedside approach.

Abstract
Because of the widespread use of botanicals, it has become crucial for health professionals to improve their knowledge about safety problems. Several herbal medicines contain chemicals with allergenic properties responsible for contact dermatitis. Among these, one is Rosmarinus officinalis L. (rosemary), a plant used since ancient times in folk medicine; at the present time it is used worldwide as a spice and flavouring agent, as a preservative and for medicinal and cosmetic purposes. The present article aims to revise and summarise scientific literature reporting cases of contact dermatitis caused by the use of R. officinalis as a raw material or as herbal preparations. Published case reports were researched on the following databases and search engines: PUBMED, MEDLINE, EMBASE, Google Scholar, Scopus. The used keywords were: R. officinalis and rosemary each alone or combined with the words allergy, contact dermatitis, allergic contact dermatitis, sensitisation and occupational dermatitis. The published case reports show that both rosemary extracts and raw material can be responsible for allergic contact dermatitis. Two cases related to contact dermatitis caused by cross-reactivity between rosemary and thyme were also commented. The diterpene carnosol, a chemical constituent of this plant, has been imputed as a common cause for this reaction. The incidence of contact dermatitis caused by rosemary is not common, but it could be more frequent with respect to the supposed occurrence. It seems plausible that cases of contact dermatitis caused by rosemary are more frequent with respect to the supposed occurrence, because they could be misdiagnosed. For this reason, this possibility should be carefully considered in dermatitis differential diagnosis.

Abstract
Botanical products sold in the health area are generally intended as drugs, medicinal products, food supplements or substances for therapeutic use. Use of botanicals for improving or to care human health has evolved independently in different countries worldwide. Regulatory issues regarding botanical products designed for the food supplements or medicinal market and their influence on research and development are discussed. European Union (EU) and United States (US) policies regulating these products are focused with comments on the legislations delivered during the last ten years and differences existing in rules between these countries are emphasized. Research and development on botanical products nowdays strongly influenced by the product destination in the market. Addressed and differentiated research for either food supplements or medicinal markets is necessary to purchase data really useful for assessment of safe and effective use for both the categories. The main objective is to catalyze interest of academic and companies' researchers on crucial aspects to be taken into account in the research for the development of botanical products.

Abstract
This study investigated the antidepressant activity of ethanolic extract of U. lanosa Wallich var. appendiculata Ridsd (UL(EtOH)) for two-weeks administrations by using FST and TST on mice. In order to understand the probable mechanism of antidepressant-like activity of UL(EtOH) in FST and TST, the researchers measured the levels of monoamines and monoamine oxidase activities in mice brain, and combined the antidepressant drugs (fluoxetine, imipramine, maprotiline, clorgyline, bupropion and ketanserin). Lastly, the researchers analyzed the content of RHY in the UL(EtOH). The results showed that UL(EtOH) exhibited antidepressant-like activity in FST and TST in mice. UL(EtOH) increased the levels of 5-HT and 5-HIAA in cortex, striatum, hippocampus, and hypothalamus, the levels of NE and MHPG in cortex and hippocampus, the level of NE in striatum, and the level of DOPAC in striatum. Two-week injection of IMI, CLO, FLU and KET enhanced the antidepressant-like activity of UL(EtOH). UL(EtOH) inhibited the activity of MAO-A. The amount of RHY in UL(EtOH) was 17.12 mg/g extract. Our findings support the view that UL(EtOH) exerts antidepressant-like activity. The antidepressant-like mechanism of UL(EtOH) may be related to the increase in monoamines levels in the hippocampus, cortex, striatum, and hypothalamus of mice.

Abstract
Danggui Buxue Tang (DBT), a Chinese herbal decoction used to treat ailments in women, contains Radix Astragali (Huangqi; RA) and Radix Angelicae Sinensis (Danggui; RAS). When DBT was applied onto cultured MG-63 cells, an increase of cell proliferation and differentiation of MG-63 cell were revealed: both of these effects were significantly higher in DBT than RA or RAS extract. To search for the biological markers that are specifically regulated by DBT, DNA microarray was used to reveal the gene expression profiling of DBT in MG-63 cells as compared to that of RA- or RAS-treated cells. Amongst 883 DBT-regulated genes, 403 of them are specifically regulated by DBT treatment, including CCL-2, CCL-7, CCL-8, and galectin-9. The signaling cascade of this DBT-regulated gene expression was also elucidated in cultured MG-63 cells. The current results reveal the potential usage of this herbal decoction in treating osteoporosis and suggest the uniqueness of Chinese herbal decoction that requires a well-defined formulation. The DBT-regulated genes in the culture could serve as biological responsive markers for quality assurance of the herbal preparation.

Abstract
Safety pharmacology studies help in identifying preclinical adverse drug reactions. We carried out routine safety pharmacology with focus on cardiovascular variables and pharmacokinetic herb-drug interaction studies on rats fed with standardized traditional hydro-alcoholic extract and technology-based supercritical extract of Cassia auriculata for 12 weeks. Our studies indicate that both these extracts are pharmacologically safe and did not show any significant adverse reactions at the tested doses. The traditional hydro-alcoholic extract did not show any significant effect on pharmacokinetics; however, the technology-based supercritical extract caused a significant reduction in absorption of metformin. Our results indicate the need to include pharmacokinetic herb-drug interaction studies as evidence for safety especially for technology-based extracts.

Abstract
Traditional medicine refers to health practices, approaches, knowledge and beliefs incorporating plant, animal and mineral based medicines, spiritual therapies, manual techniques and exercises, applied singularly or in combination to treat, diagnose and prevent illnesses or maintain well-being. In the last decade traditional medicine has become very popular in Cameroon, partly due to the long unsustainable economic situation in the country. The high cost of drugs and increase in drug resistance to common diseases like malaria, bacteria infections and other sexually transmitted diseases has caused the therapeutic approach to alternative traditional medicine as an option for concerted search for new chemical entities (NCE). The World Health Organisation (WHO) in collaboration with the Cameroon Government has put in place a strategic platform for the practice and development of TM in Cameroon. This platform aims at harmonizing the traditional medicine practice in the country, create a synergy between TM and modern medicine and to institutionalize a more harmonized integrated TM practices by the year 2012 in Cameroon. An overview of the practice of TM past, present and future perspectives that underpins the role in sustainable poverty alleviation has been discussed. This study gives an insight into the strategic plan and road map set up by the Government of Cameroon for the organisational framework and research platform for the practice and development of TM, and the global partnership involving the management of TM in the country.

METHODS: Cinnamon extract was used to treat murine macrophage cell line (Raw 264.7), mouse primary antigen-presenting cells (APCs, MHCII+) and CD11c+ dendritic cells to analyze the effects of cinnamon extract on APC function. The mechanisms of action of cinnamon extract on APCs were investigated by analyzing cytokine production, and expression of MHC antigens and co-stimulatory molecules by quantitative real-time PCR and flow cytometry. In addition, the effect of cinnamon extract on antigen presentation capacity and APC-dependent T-cell differentiation were analyzed by [H3]-thymidine incorporation and cytokine analysis, respectively. To confirm the anti-inflammatory effects of cinnamon extract in vivo, cinnamon or PBS was orally administered to mice for 20 d followed by induction of experimental colitis with 2,4,6 trinitrobenzenesulfonic acid. The protective effects of cinnamon extract against experimental colitis were measured by checking clinical symptoms, histological analysis and cytokine expression profiles in inflamed tissue.
RESULTS: Treatment with cinnamon extract inhibited maturation of MHCII+ APCs or CD11c+ dendritic cells (DCs) by suppressing expression of co-stimulatory molecules (B7.1, B7.2, ICOS-L), MHCII and cyclooxygenase (COX)-2. Cinnamon extract induced regulatory DCs (rDCs) that produce low levels of pro-inflammatory cytokines [interleukin (IL)-1β, IL-6, IL-12, interferon (IFN)-γ and tumor necrosis factor (TNF)-α] while expressing high levels of immunoregulatory cytokines (IL-10 and transforming growth factor-β). In addition, rDCs generated by cinnamon extract inhibited APC-dependent T-cell proliferation, and converted CD4+ T cells into IL-10high CD4+ T cells. Furthermore, oral administration of cinnamon extract inhibited development and progression of intestinal colitis by inhibiting expression of COX-2 and pro-inflammatory cytokines (IL-1β, IFN-γ and TNF-α), while enhancing IL-10 levels.
CONCLUSION: Our study suggests the potential of cinnamon extract as an anti-inflammatory agent by targeting the generation of regulatory APCs and IL-10+ regulatory T cells.

Abstract
Flos carthami is a traditional Chinese herbal medicine. Clinically, the Flos carthami Injection has been used concomitantly with other Western drugs and may be used concomitantly with β-blockers, such as metoprolol, to treat cerebrovascular and coronary heart diseases, in China. Metoprolol is a CYP2D6 substrate and is predominantly metabolized by this isozyme. However, we do not know whether there is an effect of Flos carthami on CYP2D6 and the consequences of such an effect. Concern is raised regarding the possible herb-drug interaction. In this report, the effects of Flos carthami on the activity of CYP2D6 in vivo and in vitro and on the pharmacokinetics of metoprolol, in rats, are investigated. To assess the inhibitory potency of Flos carthami, the concentration associated with 50% inhibition (IC50) of dextromethorphan metabolism was determined based on the concentration-inhibition curves. The inhibitory effect of Flos carthami on CYP2D6 was also compared with cimetidine in vitro. Flos carthami could significantly inhibit CYP2D6 in rats both in vitro and in vivo (P < .05) and could slow down the metabolic rate of metoprolol as suggested by prolonged t1/2 (67.45%), by increased Cmax (74.51%) and AUC0−∞ (76.89%). These results suggest that CYP2D6 is a risk factor when Flos carthami is administered concomitantly with metoprolol or other CYP2D6 substrates.

Abstract
The classic view on the pathogenesis of drug-induced liver injury is that the so-called parent compounds are made hepatotoxic by metabolism (formation of neo-substances that react abnormally), mainly by cytochromes P-450 (CYP), with further pathways, such as mitochondrial dysfunction and apoptosis, also playing a role. Risk factors for drug-induced liver injury include concomitant hepatic diseases, age and genetic polymorphisms of CYP. However, some susceptibility can today be predicted before drug administration, working on the common substrate, by phenotyping and genotyping studies and by taking in consideration patients’ health status. Physicians should always think of this adverse effect in the absence of other clear hepatic disease. Ethical and legal problems towards operators in the health care system are always matters to consider.

Abstract
Harmonization of the market for herbal medicines is a fundamental requirement for European industries and health professionals and it will also be useful for consumers. Herbal medicines are generally sold as food supplements, but a common regulatory status in the various European countries does not exist. As a consequence, information on clinical indications for use, efficacy and safety are influenced by different opinions, according to the clinical or traditional experience of various folk medicines available in each European country. The European Directive 2004/24/EC released in 2004 by the European Parliament and by the Council of Europe provides the basis for the use of herbal medicines in Europe going forward. The Directive establishes that herbal medicines released in the market need authorization by the national regulatory authorities of each European country and that these products must have a recognized level of safety and efficacy. The safety of herbal medicinal products will be evaluated on the basis of existing scientific literature (data from clinical studies, case reports, pre-clinical studies). When data on safety are not sufficient, it will be communicated to consumers. According to the criteria of safety and efficacy, we will have two kinds of herbal medicinal products in the future: (i) 'well established use herbal medicinal products' (medicinal herbs with a recognized level of safety and efficacy); and (ii) 'traditional use herbal medicinal products'. The later category will include those medicinal herbs that do not have a recognized level of efficacy but are acceptably safe. Even though the fundamental objective of the new European herbal legislation is the harmonization of the market of herbal medicines, important regulations have been introduced, which will contribute to safer use of herbal substances if adopted by the whole of the European community.
