Preservation of phenolic compounds on dried leaf infusion of Bauhinia forficata Link

Abstract Bauhinia forficata Link aqueous extract is usually recommended as a phytomedicine to reduce blood glucose levels and its biological activity has been linked to the presence of phenolic compounds from B. forficata preparations. Several drying processes are used in the production of dry herbal extracts, which may influence the chemical composition and efficacy of final herbal medicines. Due to significant chemical changes, defining appropriate drying processes is essential for phytopharmaceutical drug development. In view of this, we analyzed dried B. forficata leaf infusion (BFLI) extracts by HPLC-UV-MSn, followed by molecular networking analysis to evaluate the chemical profiles from dried extracts yielded by freeze-and spray-drying processes. The main metabolites detected included 11 ferulic/isoferulic acid derivatives and 13 glycosylated flavonoids. The qualitative chemical profiles were alike for both drying processes, whereas the relative abundance of some flavonoids was higher using spray-drying. Taken together, our results showed that freeze-and spray-drying preserved the phenolic profile of BFLI and suggested that spray-drying may be the most suitable to obtain its dried products. Along with studying the chemical profiles of dried herbal extracts, evaluating the influence of drying processes on the quality and chemical profiles of final products is pivotal and may benefit future research.

Effect of herbal medicine daikenchuto on gastrointestinal symptoms following laparoscopic colectomy in patients with colon cancer: A prospective randomized study.

We conducted a prospective randomized study to investigate the effect of daikenchuto (DKT) on abdominal symptoms following laparoscopic colectomy in patients with left-sided colon cancer. Patients who suffered from abdominal pain or distention on postoperative day 1 were randomized to either the DKT group or non-DKT group. The primary endpoints were the evaluation of abdominal pain, abdominal distention, and quality of life. The metabolome and gut microbiome analyses were conducted as secondary endpoints. A total of 17 patients were enrolled: 8 patients in the DKT group and 9 patients in the non-DKT group. There were no significant differences in the primary endpoints and postoperative adverse events between the two groups. The metabolome and gut microbiome analyses showed that the levels of plasma lipid mediators associated with the arachidonic acid cascade were lower in the DKT group than in the non-DKT group, and that the relative abundance of genera Serratia and Bilophila were lower in the DKT group than in the non-DKT group. DKT administration did not improve the abdominal symptoms following laparoscopic colectomy. The effects of DKT on metabolites and gut microbiome have to be further investigated.

The use of complementary and alternative medicine among hypertensive and type 2 diabetic patients in Western Jamaica: A mixed methods study.

BACKGROUND: The simultaneous or intermittent use of alternative treatments and prescription medications for hypertension and type 2 diabetes mellitus can have adverse health effects. OBJECTIVES: To identify beliefs and practices associated with the use of alternative treatments for hypertension and type 2 diabetes mellitus among patients. METHODS: A mixed-methods study including an investigator-administered survey and focus group discussion sessions using convenience sampling was conducted among patients aged ≥18 years during May to August 2018. Descriptive statistics were used to describe and compare demographic characteristics among groups of survey participants using JMP Pro 14.0. Thematic analysis was conducted to analyze the qualitative data using NVivo. RESULTS: Most study participants (87-90%) were on prescription medication for their condition. Of survey participants, 69% reported taking their medication as prescribed and 70% felt that prescription medicine was controlling their condition. Almost all participants (98%) reported using alternative treatments, mainly herbal medications, and 73-80% felt that herbal medicines controlled their conditions. One-third believed that herbal medicines are the most effective form of treatment and should always be used instead of prescription medication. However, most participants (85%) did not believe that prescription and herbal treatments should be used simultaneously. Most (76-90%) did not discuss herbal treatments with their healthcare providers. Four themes emerged from the focus group sessions: 1) Simultaneous use of herbal and prescription medicine was perceived to be harmful, 2) Patients did not divulge their use of herbal medicine to healthcare providers, 3) Alternative medicines were perceived to be highly effective, and 4) Religiosity and family elders played key roles in herbal use. CONCLUSIONS: This study provides useful insights into perceptions and use of alternative treatments by patients that can be used by healthcare providers in developing appropriate interventions to encourage proper use of prescription medicines and alternative medicines resulting in improved management of these chronic diseases.

Can herbal medicinal products or preparations alleviate neuropathic pain in adults? A Cochrane Review summary with commentary.

BACKGROUND: Several medicines have been shown to be effective in treating neuropathic pain, but they can have damaging side effects, therefore people are now trying herbal products to help relieve pain. OBJECTIVE: The aim of the Cochrane Review was to evaluate whether herbal products/preparations have an analgesic effectiveness in neuropathic pain and whether any side effects are associated with their use. METHODS: The population addressed were adults aged ≥18 years, suffering from chronic neuropathic pain. Studies that investigated the effects of herbal products/preparations for the relief of neuropathic pain compared to any or no interventions were included. RESULTS: Included studies did not show that herbal products/preparations have reduced pain intensity of 30% or above and there was no observable reduction in the total pain score. CONCLUSIONS: There is insufficient evidence to suggest that herbal products/preparations have any efficacy in any neuropathic pain conditions. The current evidence is of very low quality resulting in serious uncertainties about the estimates of effect observed.

Current herbal medicine as an alternative treatment in dentistry: In vitro, in vivo and clinical studies.

Since the time that human population comprehended the importance of general health maintenance and the burden of disease, there has been a search for healing properties in the natural environment. Herbal medicine is the use of plants with medical properties for prevention and treatment of conditions that can affect general health. Recently, a growing interest has been observed toward the use of traditional herbal medicine alongside synthetic modern drugs. Around 80% of the population, especially in developing countries relies on it for healthcare. Oral healthcare is considered a major part of general health. According to the world health organization (WHO), oral health is considered an important part of general health and quality of life. The utilization of natural medications for the management of pathologic oro-dental conditions can be a logical alternative to pharmaceutical methods due to their availability, low costs, and lower side effects. The current literature review aimed at exploration of the variety and extent of herbal products application in oral health maintenance including different fields of oral healthcare such as dental caries, periodontal maintenance, microbial infections, oral cancers, and inflammatory conditions.

Application of Herbaceous Medications for Inflammatory Bowel Disease as a Complementary and Alternative Therapy.

BACKGROUND: Conventional medicine for the treatment of IBD is prevailingly composed of sulfadiazine, 5-aminosalicylic acid, glucocorticoid, and immunosuppressants, which have the merits of alleviating intestine inflammation, but long-term use of these drugs may cause toxic side effects; additionally, these drugs may be expensive. In the pursuit of novel and more economic therapies, patients may increasingly look at complementary and alternative medicine (CAM). Recently, CAM is increasingly favored by the general public on account of its safety, low toxicity, and effectiveness. As a branch of CAM, herbal plants and their extracts have a significant effect on the treatment of IBD. Treatment of IBD with herbaceous plants has been reported, but specific mechanisms and effects have not yet been elaborated. METHODS: English abstracts were identified in PubMed and Science Direct by multiple search terms, such as "herbal," "CAM," "IBD," "ulcerative colitis," "abdominal pain," and so on. Full-length articles were selected for review. RESULTS: Herbaceous plants and their extracts have been shown to be effective against IBD in many studies, and herbaceous plants may be effective in treating symptoms such as abdominal pain, diarrhea, mucus, and bloody stools. CONCLUSIONS: Herbal medications could be used as a complementary and alternative treatment for IBD, but they require more rigorous scientific testing.

What motivates new, established and long-term users of herbal medicine: is there more than push and pull?

BACKGROUND: The use of herbal medicine (HM) has become an essential form of treatment and it is more and more common around the world. Little is known about the reasons that drive people to initially use HM or to maintain their behaviour, and whether the so-called "push and pull factors" known in the context of decision making for complementary and alternative medicine, also play a role for HM use. Here, our goal was to provide answers to these open questions and to analyse the reasons that motivate new, established and long-term HM consumers in detail. METHODS: Thirteen reasons for HM usage, which were previously identified within a qualitative approach, were analysed quantitatively in a nationwide online survey in Germany. Data of 2,192 German HM users from the general population were grouped into new, established and long-term users. We performed a factor analysis in order to identify factors underlying the set of reasons. RESULTS: We discovered a reliable factor associated with longstanding family traditions and cultural importance of HM in Germany. This finding shows that the reasons for HM use require a three-factor structure going beyond the well-known push and pull factors that explain the use of complementary and alternative medicine. In using the identified factors for further calculations, we were able to reveal important group differences and test how the factor scores perform as predictors for the new, established and long-term choice of HM. Our results showed that a high score on the push factor is associated more with initial HM usage, while long-term HM usage is impacted more by high scores on the pull and traditional factors. CONCLUSIONS: Our exploratory survey and analysis of the reasons that underlie HM usage aimed at providing a better understanding of the decision for this treatment form. The findings of our work deliver insights for medical practitioners and health-care providers, including the role of family traditions for HM usage and the finding that new HM users are driven to use this treatment form in part because of negative aspects they associate with conventional medicine.

A systematic review of herbal medicines for the treatment of cancer cachexia in animal models.

OBJECTIVE: The aim of this study is to summarize preclinical studies on herbal medicines used to treat cancer cachexia and its underlying mechanisms. METHODS: We searched four representing databases, including PubMed, EMBASE, the Allied and Complementary Medicine Database, and the Web of Science up to December 2016. Randomized animal studies were included if the effects of any herbal medicine were tested on cancer cachexia. The methodological quality was evaluated by the Collaborative Approach to Meta-Analysis and Review of Animal Data from Experimental Studies (CAMARADE) checklist. RESULTS: A total of fourteen herbal medicines and their compounds were identified, including Coptidis Rhizoma, berberine, Bing De Ling, curcumin, Qing-Shu-Yi-Qi-Tang, Scutellaria baicalensis, Hochuekkito, Rikkunshito, hesperidin, atractylodin, Sipjeondaebo-tang, Sosiho-tang, Anemarrhena Rhizoma, and Phellodendri Cortex. All the herbal medicines, except curcumin, have been shown to ameliorate the symptoms of cancer cachexia through anti-inflammation, regulation of the neuroendocrine pathway, and modulation of the ubiquitin proteasome system or protein synthesis. CONCLUSIONS: This study showed that herbal medicines might be a useful approach for treating cancer cachexia. However, more detailed experimental studies on the molecular mechanisms and active compounds are needed.

Understanding element composition of medicinal plants used in herbalism-A case study by analytical atomic spectrometry.

This review article is focused on element composition of medicinal plants and herbs as well as their decoctions and infusions determined by atomic spectrometry methods. Considering quality and safety of these herbal beverages, widely practiced in herbalism for medicinal and supplementing purposes, element analysis is important, and quality of its results should not raise any doubts about reliability. Hence, original researches devoted to element analysis of decoctions and infusions of medicinal plants and herbs, published after 2000, have been surveyed in details, particularly focusing on sources of elements in medicinal plants, their availability for the intake during preparation of infusions and decoctions as well as different methodological aspects related to element analysis by atomic spectrometry, including sample pretreatment and preparation before measurements, calibration methods used, and verification of reliability of results.

Herbal medicines in the treatment of psychiatric disorders: 10-year updated review.

This paper provides a 10-year update of the 2007 systematic review of herbal medicines studied in a broad range of psychiatric disorders, including depression, anxiety, obsessive-compulsive, seasonal affective, bipolar, psychotic, phobic, somatoform, and attention-deficit hyperactivity disorders. Ovid Medline, PubMed, and the Cochrane Library were searched for herbal medicines with both pharmacological and clinical evidence of psychotropic activity. This updated review now covers clinical trial evidence for 24 herbal medicines in 11 psychiatric disorders. High-quality evidence was found to exist for the use of Piper methysticum (Kava), Passiflora spp. (passionflower) and Galphimia glauca (galphimia) for anxiety disorders; and Hypericum perforatum (St John's wort) and Crocus sativus (saffron) for major depressive disorder. Other encouraging herbal medicines with preliminary evidence include Curcuma longa (turmeric) in depression, Withania somnifera (ashwagandha) in affective disorders, and Ginkgo biloba (ginkgo) as an adjunctive treatment in Schizophrenia. Although depression and anxiety are commonly researched, many other mental disorders still require further prospective investigation. Although the previous review suggested increasing the adjunctive study of select herbal medicines with pharmaceuticals, this was still only found to sparingly occur in research designs. Aside from this, future focus should involve the incorporation of more biomarker analysis, in particular pharmacogenomics, to determine genetic factors moderating response to herbal medicines.

Herbal Products for Common Auto-Inflammatory Disorders - Novel Approaches.

BACKGROUND: Common auto-inflammatory disorders (CAIDs) constitute a wide array of ailments ranging from acute allergies to chronic conditions. Globally, CAIDs remain one of the leading causes of disability and morbidity. Despite playing a leading therapeutic role, the vast profusion of anti-inflammatory synthetic agents have not been able to fully resolve a panoply of CAIDs. Additionally, contemporary synthetic therapy approaches remain bounded by a wide array of limitations essentially being adverse effects and unaffordable costs. In this advent, the use of herbal products provides an interesting avenue to explore in view of developing such treatment regimens. OBJECTIVE: This review article endeavors to highlight potential herbal products and isolated phytochemicals which can be of benefit in the prophylaxis, management, and treatment alongside avoiding the relapse of CAIDs. CONCLUSION: This review article has highlighted that herbals, herbal products, and isolated metabolites hold a huge potential in the prophylaxis, management, and treatment of CAIDs. Herbals can act on various targets involved in the pathogenesis of inflammatory disorders. In addition, novel approaches for the management of CAIDs are numerous. Indeed, nanoparticles loaded with phytochemicals have been developed to specifically target the colon for IBD treatment. In silico approaches using herbals also offer unlimited avenues to decipher new pharmacophores. Investigating the potential of polyherbal formulations is another unique approach which can be investigated. Given the inefficacy of conventional medicines, the concomitant use of conventional and herbal medicines can also be explored.

A Literature Review of Alternative Therapies for Postpartum Depression.

Postpartum depression is a debilitating disorder that requires greater awareness and treatment. Depending on severity of symptoms, standard treatment calls for individual psychotherapy and medication. Although postpartum depression can lead to negative health outcomes for women and their offspring, numerous barriers prevent women from receiving appropriate care. A review of the literature shows that nontraditional modes of psychotherapy dominate recent studies, whereas data for other complementary options are severely lacking. Further research is needed to help identify cost-effective alternative therapies for treating postpartum depression. Combined with prevention and screening, treatment options that suit women's varied situations and preferences must be explored to increase reception and adherence to treatment and, ultimately, to improve outcomes.

Mechanistic Understanding of Herbal Therapy in Inflammatory Bowel Disease.

The incidence and prevalence of inflammatory bowel diseases (IBD), which comprise ulcerative colitis and Crohn's disease, are increasing dramatically worldwide. Immunomodulators and biological agents can help but cause severe side effects in long-term use. As such, complementary and alternative medicine, in particular herbal remedy, is becoming more and more popular in the treatment of IBD patients. Many natural compounds have been used in clinical trials and some have been proven promising in IBD treatment. To achieve a better understanding of herbal therapy, researchers focus on understanding the underlying mechanisms by using experimental rodent models. The mechanism of the pathogenesis of IBD is complex involving both environmental and genetic factors. IBD is considered as a consequence of impaired epithelial barrier function, gut microbiota dysbiosis, and aberrant immune response. Studies have demonstrated that herbal medicine can improve epithelial proliferation and barrier integrity, restore microbiota homeostasis, and suppress hyper-immune reaction. This review is to summarize current understanding of the molecular basis of herbal treatment of IBD at the levels of epithelial, microbial, and immune regulation.

Biological and clinical implications of herbal medicine and natural products for the treatment of inflammatory bowel disease.

Inflammatory bowel disease (IBD) is a group of chronic inflammatory disorders that includes Crohn's disease (CD) and ulcerative colitis (UC). Homeostasis of various regulatory factors involved with intestinal immunity is disrupted in IBD, including the intestinal epithelial barrier, macrophages, and cellular mediators such as cytokines and chemokines. No successful treatment is currently available for the management of IBD. Natural products and herbal medicines have exhibited efficacy for UC and CD in experimental models and clinical trials with the following activities: (1) maintenance of integrity of the intestinal epithelial barrier, (2) regulation of macrophage activation, (3) modulation of innate and adaptive immune response, and (4) inhibition of TNF-α activity. Here, we discuss the major factors involved in the pathogenesis of IBD and the current development of natural products and herbs for the treatment of IBD.

Demystifying traditional herbal medicine with modern approach.

Plants have long been recognized for their therapeutic properties. For centuries, indigenous cultures around the world have used traditional herbal medicine to treat a myriad of maladies. By contrast, the rise of the modern pharmaceutical industry in the past century has been based on exploiting individual active compounds with precise modes of action. This surge has yielded highly effective drugs that are widely used in the clinic, including many plant natural products and analogues derived from these products, but has fallen short of delivering effective cures for complex human diseases with complicated causes, such as cancer, diabetes, autoimmune disorders and degenerative diseases. While the plant kingdom continues to serve as an important source for chemical entities supporting drug discovery, the rich traditions of herbal medicine developed by trial and error on human subjects over thousands of years contain invaluable biomedical information just waiting to be uncovered using modern scientific approaches. Here we provide an evolutionary and historical perspective on why plants are of particular significance as medicines for humans. We highlight several plant natural products that are either in the clinic or currently under active research and clinical development, with particular emphasis on their mechanisms of action. Recent efforts in developing modern multi-herb prescriptions through rigorous molecular-level investigations and standardized clinical trials are also discussed. Emerging technologies, such as genomics and synthetic biology, are enabling new ways for discovering and utilizing the medicinal properties of plants. We are entering an exciting era where the ancient wisdom distilled into the world's traditional herbal medicines can be reinterpreted and exploited through the lens of modern science.

Use of traditional herbal medicine as an alternative in dental treatment in Mexican dentistry: a review.

CONTEXT: Herbal therapies are used worldwide to treat health conditions. In Mexico, generations have used them to treat gingivitis, periodontitis, mouth infections, and discoloured teeth. However, few studies have collected scientific evidence on their effects. OBJECTIVE: This study aimed at searching and compiling scientific evidence of alternative oral and dental treatments using medicinal herbs from Mexico. METHODS: We collected various Mexican medicinal plants used in the dental treatment from the database of the Institute of Biology at the National Autonomous University of Mexico. To correlate with existing scientific evidence, we used the PubMed database with the key term '(scientific name) and (oral or dental)'. RESULTS: Mexico has various medical herbs with antibacterial and antimicrobial properties, according to ancestral medicinal books and healers. Despite a paucity of experimental research demonstrating the antibacterial, antimicrobial, and antiplaque effects of these Mexican plants, they could still be useful as an alternative treatment of several periodontal diseases or as anticariogenic agents. However, the number of studies supporting their uses and effects remains insufficient. DISCUSSION AND CONCLUSION: It is important for the health of consumers to scientifically demonstrate the real effects of natural medicine, as well as clarify and establish their possible therapeutic applications. Through this bibliographical revision, we found papers that testify or refute their ancestral uses, and conclude that the use of plants to treat oral conditions or to add to the dental pharmacological arsenal should be based on experimental studies verifying their suitability for dental treatments.
