Background: Functional dyspepsia (FD) is a common gastrointestinal disease that is highly prevalent worldwide. Because of its heterogeneous pathophysiology, treatment options for FD can be difficult to choose; in this context, complementary and alternative medicine modalities have been suggested as promising options., Aim: To evaluate the efficacy of a traditional Persian medicine, jollab, in reducing patients' FD symptoms., Methods: In a double-blind randomized clinical trial, 160 patients with a diagnosis of FD were enrolled and treated with either jollab or placebo (15ml, t.i.d., four weeks, orally). The outcomes reported were changes in symptom frequency and severity as recorded in patients' diaries and evaluated with the Short Form of the Leeds Dyspepsia Questionnaire (SF-LDQ), and physical examination., Results: The response rate was higher in the treatment group (78%) than in the placebo group (31%) according to per-protocol sample analysis (P < .001). Symptoms of FD disappeared significantly more frequently, and the rate of concomitant synthetic drug consumption was significantly lower, in the jollab group compared to the placebo group at the end of the trial. Mean total symptom frequency and severity according to the SF-LDQ score was 1.55 ± 2.78 in the treatment group versus 5.61 ± 3.80 in the placebo group at the last follow-up time point (P < .001). A promising safety profile for jollab was observed throughout the trial., Conclusions: In patients with FD, jollab appeared to be more effective than the placebo. Complementary and alternative therapies such as the use of this traditional medicinal substance may be beneficial in relieving symptoms of dyspepsia [ACTRN12613000584730]., (Copyright © 2015 Elsevier Inc.

Ethnopharmacological Relevance: By studying the Iranian Traditional Medicine (ITM) Pharmacopoeia, we have collected information about medicinal plants which had been used to manage cancer-like disorders over eight hundred years, from medieval to the early modern era. Exploring the ITM herbal knowledge, the selected species have been subjected to MTT assay for examining their in vitro cyototoxic activity., Materials and Methods: Cancer was reviewed through the ITM and some terminologies were acquired. Five ITM Pharmacopoeia in Arabic and Persian languages from 10th to 18th century AD were explored. These Pharmacopoeia contained the ITM plants which were used to cure cancer and cancer-like diseases. The ITM names were matched with the scientific names. Then the medicinal plants were collected, authenticated and were evaluated for cytotoxic activity using MTT assay, against MCF-7, HepG-2, A-549 and HT-29 cell lines. Finally, the apoptosis induction ability of the most cytotoxic medicinal plant was investigated by activated caspase 3 inspection in MCF-7 cell line., Results: Six species of the evaluated medicinal plants revealed cytotoxic activity. The most cytotoxicity was observed in Tanacetum polycephalum subsp. argyrophyllum (K.Koch) Podlech with IC50 values of 28.3 μg mL(-1), 53.9 μg mL(-1) and 43.3 μg mL(-1) against MCF-7, A-549 and HT-29 cell lines, respectively. Caspase 3 activation was also observed in MCF-7 cells by Tanacetum polycephalum subsp. argyrophyllum. This is the first time that the cytotoxic activity of this species has been reported., Conclusion: In the present study, some reliable references of ITM have been introduced and though many technical difficulties, linguistic problems and some other hindrances were encountered during the study, using traditional medicine texts for medicinal plant selection could be considered as a helpful starting point in the field of cancer drug discovery., (Copyright © 2014 Elsevier Ireland Ltd.

Ethnopharmacological Relevance: Medicinal plants are an important element of medical system. These resources are usually regarded as part of cultural traditional knowledge. We present for the first time the results of an ethnobotanical survey in Kohghiluyeh va Boyer Ahmad province of Iran, conducted between 2008 and 2010. This information could be the basis of an evidence based investigation to discover new drugs., Materials and Methods: Ethnobotanical data were analyzed by use-reports in addition important indices like relative frequency of citation (RFC) and cultural importance index (CI) were calculated. Totally 23 informants were interviewed., Results: Our study reports 138 traditionally used plant species, belonging to 52 plant families from this province. Asteraceae and Lamiaceae are the dominant locally used families. The highest number of species and application were reported for digestive system disorder, metabolic disorder and respiratory system, respectively. The part of the plant most frequently used was the aerial part (31.9%), leaves (14.8%) and fruits (11.7%). The plants are used both for medicinal and non-medicinal purposes. Daphne mucronata Royle. and Teucrium polium L. have the largest value of relative frequency of citation and cultural importance index, respectively., Conclusion: Kohghiluyeh va Boyer Ahmad has good ethnobotanical potential for medicinal plants. This study is the first contribution to the ethnobotany of this region. We have gathered from this province some considerable knowledge about local medicinal plants for treating common health problem that is ready to be further investigated in the laboratory., (Copyright © 2012 Elsevier Ireland Ltd.
