Background: Cough is one of the most common medical symptoms for which medical advice is sought. Although cough is a protective reflex responsible for clearing the airways from secretions and foreign bodies, it can be a troublesome symptom that causes discomfort to patients. Due to the increasing interest in herbal remedies in the both developed and developing countries, in the current study, we aimed to overview medicinal herbs containing essential oils used as antitussive agents according to the Traditional Persian Medicine [TPM] textbooks. We summarized the relevant scientific evidence on their possible pharmacological actions. Methods: To collect the evidence for treatment of cough or “seaal” [cough in ancient books] from TPM sources, five main medicinal Persian manuscripts were studied. The antitussive herbs were listed and their scientific names were identified and authenticated in accordance with botanical reference books. ScienceDirect and PubMed online databases were searched for related mechanisms of action of the reported medicinal plants. Results: The number of 49 herbs containing essential oils were recommended in TPM for the treatment of cough; 21 of them had at least one known mechanism of action for cough suppression in the scientific literature. According to this review, most of the cited medicinal plants were assessed for either nitric oxide inhibitory or antitussive/expectorant activities. Conclusion: In addition to advantageous effects of antitussive herbs noted by TPM, the present review highlighted some recent evidence-based data on these promising candidates that could be used as an outline for future research on their medicinal use.

The immune modulating effects of selected herbs deserve careful studies to gain evidence-based support for their further development. We have been working hard on many items of medicinal herbs to gain insight into their immunomodulatory effects relevant to cancer treatment in particular, while infection control is not excluded. Nine of them have been selected to give the results of our exploration on their biological, particularly immunomodulatory activities. Since Hong Kong people especially favor one medicinal mushroom, viz. Coriolus versicolor, a number of clinical trials using Coriolus for cancer-related studies are included in this review. While immune modulation platforms are being built for relevant studies, a brief account on the research targets and related procedures are given.

This study was carried out in order to set up an inventory list of medicinal plants used in traditional medicine to treat diabetes for which an ethnobotanical test was carried out on 670 diabe c subjects in the Western region of Algeria (Chlef, Mostaganem, Mascara, Oran, Sidi-bel-Abbes, Saida and Tiaret) using a survey. 24 an hyperglycemic medicinal plants were listed of which Berberis vulgaris, Zygophyllum geslini, Erythraea centaurium and Olea eu- ropea represented a broad spectrum of use. Likewise, the an hyperglycemic recipes were prepared mainly in decoc on (45.37%) and infusion (39.62%), and from leaves (42%) and aerial parts (16%). A very valuable data base has been reported for further research, especially for some elds such as phytochemistry and phytopharmacology that aim to identify new natural principles.

ABSTRACTAn ethnobotanical study of medicinal plants was carried in the province of Sidi Kacem (Morocco), whose objective is to make an inventory of medicinalplants used in traditional therapy against respiratory, digestive, and cutaneous infections; also to describe their mode of use practiced by the localpopulation. The tool of the study was a questionnaire completed by 200 citizens of four investigated areas, determined by the stratified samplingtechniques, 40% practiced phytotherapy. The survey consists of a section on the informant, and another is interested in plants used by the population.The analysis of information has established a catalog of 73 species identified with their use of frequencies, partly used and the method of preparation.They belong to 39 families; the most dominant are Lamiaceae, Apiaceae, and Asteraceae. The leaves are the most used part in decoction to treat thethree types of infection mentioned above. These results allow us to create a database about this region’s plants characteristic. They will be useful toestablish further studies on their chemical properties and biological activities.Keywords: Province of Sidi Kacem (Morocco), Phytotherapy, Ethnobotanical survey, Infections, Catalogue of plants.
