Ethnopharmacological approach to the herbal medicines of the "Elements Alpha to Delta" in Nikolaos Myrepsos׳ Dynameron. Part II.

ETHNOPHARMACOLOGICAL RELEVANCE

Dynameron is a Byzantine medical compendium, divided into 24 sections, the "Elements", containing 2667 recipes, most of which inherited by previous physicians of the classic ancient Greek and Hellenistic, and imperial Roman periods.

AIM OF THE STUDY

In continuation to our previous study concerning the first and largest chapter of the "Element Alpha" of Nikolaos Myrepsos׳ Dynameron (Valiakos et al., 2015), this paper focuses on the plants quoted in the recipes of the eight following chapters entitled "About Salts", "About Honeypacks" and "About Spreads", all belonging to the same "Element Alpha"; "About Antitussives" and "About Suppositories" belonging to the "Element Beta"; "About women's Cathartics" belonging to the "Element Gamma"; "About Drossaton" and "About Diachrisma", both belonging to the "Element Delta".

MATERIALS AND METHODS

Our main primary source material was the codex kept in the National Library of France (in Paris) under the number grec. 2243, which is the older and larger codex of Dynameron (Valiakos et al., 2015).

RESULTS

The present study led us to the interpretation of 277 plants under different names, among which we recognized 57 medicinal plants listed by the European Medicines Agency, one of them with negative monograph (i.e. Chelidonium majus). In addition, there are identified taxa related to those quoted by EMA as herbal medicines. The plants appearing in the examined Elements belong to various families of which the most frequent are: Apiaceae 10.11%; Lamiaceae 7.22%; Asteraceae 6.86%; Rosaceae 6.5% and Fabaceae 6.14%.

CONCLUSIONS

A total of 277 species have been catalogued, most of which are referred in our previous publication (Valiakos et al., 2015). Among them, 56 plants still play a very important role in medical practice, as they are used as traditional herbal medicines (www.ema.eu). This evidence is a proof that the use of medicinal plants remains valuable from the ancient times until today. The recipes, in contrast to older medical compendia, contain precise measurements of ingredients and dosages for every drug, which seem to reflect empirical logic.
