In recent decades, the study of historical texts has attracted research interest, particularly in ethnopharmacology. All studies of the materia medica cited in ancient and medieval texts share a concern, however, as to the reliability of modern identifications of these substances. Previous studies of European or Mediterranean texts relied mostly on authoritative dictionaries or glossaries providing botanical identities for the historical plant names in question. Several identities they suggest, however, are questionable and real possibility of error exists.

Aim of the study
This study aims to develop and document a novel and interdisciplinary methodology providing more objective assessment of the identity of the plants (and minerals) described in these resources.

Materials and methods
We developed an iterative experimental approach, using the 13th century Byzantine recipe text John the Physician's Therapeutics in its Commentary version (JC) as a case study. The methodology has six stages and relies on comparative analyses including statistical evaluation of botanical descriptions and information about medicinal uses drawn from both historical and modern sources. Stages 1–4 create the dataset, stage 5 derives the primary outcomes to be reviewed by experts in stage 6.

Results
Using Disocorides’ De Materia Medica (DMM) (1st century CE) as the culturally related reference text for the botanical descriptions of the plants cited in JC, allowed us to link the 194 plants used medicinally in JC with 252 plants cited in DMM. Our test sample for subsequent analyses consisted of the 50 JC plant names (corresponding to 61 DMM plants) for which DMM holds rich morphological information, and the 130 candidate species which have been suggested in the literature as potential botanical identities of those 50 JC plant names. Statistical evaluation of the comparative analyses revealed that in the majority of the cases, our method detected the candidate species having a higher likelihood of being the correct attribution from among the pool of suggested candidates. Final assessment and revision provided a list of the challenges associated with applying our methodology more widely and recommendations on how to address these issues.

Conclusions
We offer this multidisciplinary approach to more evidence-based assessment of the identity of plants in historical texts providing a measure of confidence for each suggested identity. Despite the experimental nature of our methodology and its limitations, its application allowed us to draw conclusions about the validity of suggested candidate plants as well as to distinguish between alternative candidates of the same historical plant name. Fully documenting the methodology facilitates its application to historical texts of any kind of cultural or linguistic background.

However, they are usually not accessible as few scientists with an interest in premodern materia medica are also qualified philologists. Therefore, a balance has to be struck to translate these texts while preserving information on how reliable we believe a given translation to be. In this paper, we conduct a case study on the vernacular version of Ioannes archiatrus. Methods The present study forms part of the output of a multidisciplinary Wellcome Trust Collaborative Award combining humanities and sciences. We deployed a multi-layer tagging system to systematise pharmaceutical terminology and to translate these terms while providing confidence factors for individual words. In a second step, we used AntConc, a freeware concordance software, to analyse our primary source and visualise patterns in the text. Results Our methodology created a readable text that made it possible for the ...

Currently, little is known about the products' place in people's health care strategies and their views about such products. The aims of the study are to gain insight into the public's perception of herbal medicine/general use of herbs for health, as well as on the growing of plants for medicine. Core to the research was a survey that covered participants' views about herbal medicines. Data were collected online and from visitors at the Eden Project, as well as some other garden events. Survey responses were categorized and analysed using Qualtrics. Overall, 408 participants participated though numbers varied across questions. Results show that herbal medicines are popular, particularly amongst the 36‐ to 55‐year‐old age group. Participants mostly used herbal medicines for minor self‐limiting conditions. Popular reasons for use included that plant medicines are natural and have fewer...
