Anti-diarrheal plants of central Anatolia: Do they inhibit diarrhea-causing bacteria?

Infectious diarrhea results in 2 to 5 million deaths worldwide per year, and treatments that are safe, effective, and readily available are under investigation. The field of medicinal ethnobotany focuses on plants that are used by different cultural groups for treating various diseases and evaluates these plants for efficacy and cytotoxicity. In the present study, ethnobotanical research was conducted with Central Anatolian villagers in Turkey. Folk concepts and etiologies surrounding diarrhea were analyzed, as were salient plant-based remedies for diarrhea. Reviewing the literature, 91 plant species were described as anti-diarrheal in all of Turkey. In Central Anatolia, villagers described 35 species. For continued research via bactericidal and bacteriostatic bioassays, 15 plants were selected. Methanolic and aqueous extracts of medicinally used plant parts were evaluated for inhibitory properties against 10 diarrhea-causing bacteria in the first bioassay, and later 21 bacteria in a second assay utilizing spectrophotometry. The cytotoxic properties were also evaluated in an Alamar Blue Assay using HepG-2, PC-3, and SkMEL-5 human cell lines. While several extracts showed bactericidal and bacteriostatic properties, the methanolic extract of R. canina galls inhibited the most bacteria at the lowest concentrations. They were not cytotoxic. Thus, R. canina methanolic gall extracts were selected for bio-assay guided fractionation. Antibacterial activity was maintained in the third fraction which was composed of almost pure ellagic acid. The bioassay was repeated with standard ellagic acid, and the polyphenol retained potency in inhibiting multiple bacterial strains. Several other extracts showed promise for safe, effective anti-bacterial remedies for diarrhea.

Annona sp: Plants with multiple applications as alternative medicine - a review

Annona species have been used as a natural remedy for a variety of illnesses with antiparasitic, antispasmodic, antidiarrheal, antiulcer, sedative, analgesic, hypotensive, and vermifugal effects. These properties are due to the presence of a number of bioactive compounds on the leaves, fruit, seeds, and stem. The aim of this review is to show the main species of Annona, their medicinal properties and the chemical constituents that may be related to these effects. In the leaves it is possible to find acetogenins, annopentocins A, B, and C, cis- and trans-annomuricin-D-ones, goniothalamicin, arianacin, and javoricin, related to anticancer properties. Quercetin-3-O-glucoside, also found in the leaves mediates antidiabetic and antioxidative effects. In the fruit are found annonaine, nornuciferine and asimilobine, associated to antidepressive effects. In the seeds are found muricatetrocin A and muricatetrocin B, longifolicin, corossolin, corossolone, uvarigrandin A, bullatacin, squamotatin. These acetogenins are associated with anticancer effects. Cyclosquamosin B, quercetin, and cyclosquamosin from the seeds have respectively vasorelaxant, antithyroidal and, antiinflammatory activity. In the stem parts there are several components as N-trans-feruloyltyramine, N-p-coumaroyltyramine, and N-trans-caffeoyltyramine, lignans, syringaresinol, syringaldehyde, beta-sitosterol and beta-sitosterol-beta-D-glucoside which exhibit antiplatelet aggregation activity. Copaene, patchoulane, 1H-cycloprop (e) azulene and kaur-16-en-19-oic acid found in the barks exhibit significant central as well as peripheral analgesic and antiinflammatory activities. The properties of the biological compounds in Annona species support information that may provide validation for its medicinal uses, but further studies should be performed to establish ideal and safe doses of consumption to ensure the effectiveness of the benefits. © 2012 Bentham Science Publishers.

Exploring the use of Viagra in place of animal and plant potency products in traditional Chinese medicine

Recently, conservationists have debated whether consumers of animal and plant potency products used to treat erectile dysfunction (ED) in traditional Chinese medicine (TCM) might be switching to Viagra, consequently consuming fewer of these animals and plants. To address this question, a survey examined the medical decisions of male consumers of TCM in Hong Kong who were over the age of 50. As predicted, these consumers reported selectively switching to Western medicines to treat ED, but not to treat other health ailments. These findings provide support for the possibility that Viagra may have conservation benefits for certain species.

Report on the Regulation of Practitioners of Complementary and Alternative Medicine in Ireland

This report has been written in the context of this interest and in response to a request from the Department of Health and Children. It follows a Forum on regulatory issues that was held at the IPA in June 2001 and attended by many CAM practitioners. The Minister for Health and Children asked the Institute to build on the discussions at the Forum by preparing a report on possible options in the regulation of CAM practitioners in Ireland. The focus of the report is on regulatory and policy issues in general. It is not within the Instituteâ?Ts competence or brief to comment on more specific clinical or technical issues.

Decision-making in pediatrics: a practical algorithm to evaluate complementary and alternative medicine for children.

We herein present a preliminary practical algorithm for evaluating complementary and alternative medicine (CAM) for children which relies on basic bioethical principles and considers the influence of CAM on global child healthcare. CAM is currently involved in almost all sectors of pediatric care and frequently represents a challenge to the pediatrician. The aim of this article is to provide a decision-making tool to assist the physician, especially as it remains difficult to keep up-to-date with the latest developments in the field. The reasonable application of our algorithm together with common sense should enable the pediatrician to decide whether pediatric (P)-CAM represents potential harm to the patient, and allow ethically sound counseling. In conclusion, we propose a pragmatic algorithm designed to evaluate P-CAM, briefly explain the underlying rationale and give a concrete clinical example.

Offer and use of complementary and alternative medicine in hospitals of the French-speaking part of Switzerland.

BACKGROUND: In 2004, complementary and alternative medicine (CAM) was offered by physicians in one-third of Swiss hospitals. Since then, CAM health policy has changed considerably. This study aimed to describe the present supply and use of CAM in hospitals in the French-speaking part of Switzerland, and to explore qualitatively the characteristics of this offer. METHODS: Between June 2011 and March 2012, a short questionnaire was sent to the medical directors of hospitals (n = 46), asking them whether CAM was offered, where and by whom. Then, a semi-directive interview was conducted with ten CAM therapists. RESULTS: Among 37 responses (return rate 80%), 19 medical directors indicated that their hospital offered at least one CAM and 18 reported that they did not. Acupuncture was the most frequently available CAM, followed by manual therapies, osteopathy and aromatherapy. The disciplines that offered CAM most frequently were rehabilitation, gynaecology and obstetrics, palliative care, psychiatry, and anaesthetics. In eight out of ten interviews, it appeared that the procedures for introducing a CAM in the hospital were not tightly supervised by the hospital and were mainly based on the goodwill of the therapists, rather than clinical/scientific evidence. CONCLUSION: The number of hospitals offering CAM in the French-speaking part of Switzerland seemed to have risen since 2004. The selection of a CAM to be offered in a hospital should be based on the same procedure of evaluation and validation as conventional therapy, and if the safety and efficiency of the CAM is evidence-based, it should receive the same resources as a conventional therapy.

Parental attitude towards alternative medicine in the paediatric intensive care unit.

The interest in alternative medicine (AM) is growing. In the USA and Canada, studies showed that 34% of adults and 11% of children use AM. In a prospective cohort study, we investigated the interest in AM among parents of critically ill children in the paediatric Intensive Care Unit (ICU) of a university hospital. From January 1996 to April 1997, we distributed questionnaires to the parents of critically ill children. These strictly anonymous questionnaires were completed at home and returned by mail. Exclusion criteria were short ( < 1 day) or repeated hospitalizations, and insufficient proficiency of the German language. The inclusion criteria were fulfilled by 591 patients; 561 received the questionnaire (95%) and 289 (52%) were returned. Of the respondents, 70% would appreciate AM as a complementary therapy on the ICU, 23% found AM equally or more important than conventional medicine whereas only 7% regarded AM as unimportant. On the ICU, 18% used AM; surprisingly 41% of them did not discuss it with physicians or nurses. An additional 21% would have liked to use AM, but did not do so. Typically, AM-users administered AM also at home to their children and themselves. Their children were however, older.CONCLUSIONS: A substantial proportion of parents used measures of alternative medicine in the intensive care unit, or would have like to do so. However, few had the confidence to discuss this wish with the medical personal. This suggests that alternative medicine is of great interest, even on an intensive care unit. Nevertheless, discussion about alternative medicine seems to be taboo in doctor-patient relations.
