The natural mummy of Saint Davino Armeno (11th century) is preserved in the church of Saint Michele in Foro in the city of Lucca (Tuscany, Central Italy). The body of Davino is one of the oldest Italian mummies of a Saint, and his paleopathological study was performed in 2018. In the present research, we investigated the arthropod fragments and botanical remains collected from the body, coffin, and fabrics of Saint Davino. Entomological analyses outlined the presence of 192 arthropod fragments. Among these, Diptera, Muscidae ( Hydrotaea capensis and Muscina sp.), and Phoridae ( Conicera sp.) puparia were the most abundant. Regarding Coleoptera, Ptinidae ( Anobium punctatum ) were the most frequent, followed by Cleridae ( Necrobia sp.), Trogidae ( Trox scaber ), Curculionidae ( Sitophilus granarius ), and Histeridae ( Gnathoncus ). Cocoons of Tineidae and Pyralidae moths were found, along with a propodeum joined to the petiole and a mesopleuron of an Ichneumoninae parasitoid. Numerous metamera of Julida and three scorpion fragments were also found. Botanical samples indicated the presence of a quite broad botanical community, including gramineous species, olives, evergreen oaks, and grapevine. Overall, entomological data allow us to argue that Saint Davino was first buried into the soil, probably in a wooden coffin, thus supporting the historical-hagiographic tradition according to which he was buried sub divo in the cemetery of Saint Michele. The preservation of the body as a natural mummy may have been facilitated by burial in a coffin that prevented direct contact of the corpse with the earth. Botanical remains offer confirmation of a late medieval urban environment rich in horticultural areas and trees, giving us a landscape that is very different from the current Tuscan city., Competing Interests: The authors declare no competing interests.

Parietaria diffusa M. et K., Urtica dioica L. (Urticaceae) and Sambucus nigra L. (Caprifoliaceae) are plants usually used in popular medicine of central Italy for treating numerous diseases, first of all Herpes zoster. Several plant products have been described as potential antiviral agents, with special attention being devoted to those having retroviruses as etiological agents, including acquired immunodeficiency syndrome (AIDS), in which a retrovirus, the designated human immunodeficiency virus HIV, has been clearly identified as the primary cause of this disease. The present study proposes a preliminary screening of the antiviral activity of Parietaria diffusa, Sambucus nigra and Urtica dioica preparation against the feline immunodeficiency virus (FIV) infection. The feline immunodeficiency virus is a widespread lentivirus of domestic cats sharing numerous biological and pathogenic features with the human immunodeficiency virus (HIV). FIV infection in cats has therefore been proposed as an animal model for AIDS studies with respect to pathogenesis, chemotherapy, and vaccine development [Pedersen, N.C., 1993.

The essential oil obtained by hydrodistillation of the fresh aerial parts of Mentha microphylla C. Kock (Lamiaceae) collected on the Gennargentu Mountains (Sardinia, Italy) has been investigated by gas chromatography (GC) and GC/mass spectrometry (MS). The main constituents that resulted were pulegone (34.1%), piperitenone oxide (32.9%), and piperitenone (11.3%). The presence of small amounts of compounds such as ethyl hexanoate, 1-octen-3-ol, nonanal, and ethyl 2-methylbutanoate could justify the particular odorous profile of the plant, resembling the aroma of milk and other dairy products such as mozzarella.

We analysed the mycorrhizal types of two coastal Mediterranean plant communities. Plants belonging to 82 species of 46 families growing in two Mediterranean study sites located within a Regional Natural Park in Italy (Macchia Lucchese) and in a National Park in Croatia (Brijuni) were assessed for the type of their mycorrhizal associations. Mycorrhizas occurred in 83% and 90% of the plant species surveyed in Macchia Lucchese and in Brijuni, respectively. On the basis of macroscopic and microscopic characteristics, six different mycorrhizal types were found, and their co-occurrence in the same plant community showed the large mycorrhizal diversity in Mediterranean vegetation. Different occurrence patterns of mycorrhizal types have been recognised in diverse habitats within Macchia Lucchese, from sand dune plant communities to sclerophyllous woodland. Mycorrhizal type abundance calculated on a floristic basis was very different from that obtained using a vegetation cover index.

Tuscany is an area rich in traditions, many of an ethnobotanical nature, and those of veterinary practice are of special interest. Almost a 100 different plant species are used to treat animals; sometimes old remedies are used to cure similar human ailments, other times the cure is used exclusively for veterinary treatment.

The therapeutic uses and methods of administration of 70 plants in the traditional medicine of Sarrabus (south-east Sardinia, Italy) are documented. Among these species, some were not reported previously for Sardinia, while others turn out to have an original therapeutic use.

From an ethno-pharmacobotanical point of view, Tuscany is a region with very rich and interesting traditions. The Tuscan Archipelago, particularly due to its geographical position and its history, presents a large variety of plant species used in popular medicine in numerous pathologies, including several viral infections. Over 100 species of plants are used in popular medicine in this region.
