This estimate was accomplished through a fivefold process: (a) a review of ethnobotanical and microbiological data concerning the Italian vulnerary plants; (b) the development of a scoring system to rank the plants; (c) the comparative assessment of microbiological properties; (d) the assessment of potential cytotoxic effects on keratinocyte-like cells and gingival fibroblasts in culture by XTT cell viability assay; (e) clinical evaluation of the most suitable plant extract as antibacterial agent in a home-made mouthwash. The study assays hexane (H), ethanol (E), and water (W) extracts from 72 plants. The agar diffusion method was used to evaluate the activity against Streptococcus mutans, Streptococcus sobrinus, Lactobacillus casei, and Actinomyces viscosus. Twenty-two plants showed appreciable activity. The extracts showing the strongest antibacterial power were those from Cotinus coggygria Scop., Equisetum hyemale L., Helichrysum litoreum Guss, Juniperus communis L., and Phyllitis scolopendrium (L.) Newman subsp. scolopendrium. The potential cytotoxic effect of these extracts was assessed. On the basis of these observations, a mouth-rinse containing the ethanolic extract of H. litoreum has been tested in vivo, resulting in reduction of the salivary concentration of S. mutans.

Methods: 80 healthy patients with an age range from 10 to 18 years were recruited and randomly distributed into 2 Groups [Group A (n=40) and Group B (n=40)]. Stimulated saliva samples were collected from each subject at baseline (T0) and the plates with the samples were incubated at 37C for 48 hours on S. Mutans and Lactobacilli sensitive agar medium. Salivary colonisation of S. Mutans and Lactobacilli levels were investigated by standard Caries Risk Test (CRT) Bacteria kits. Group A subjects were instructed to rinse with 40ml of an experimental green tea mouth-rinse, for 1 minute, 3 times a day for a week, whereas Group B subjects similarly rinsed, but with 40ml of a placebo mouth-rinse. After the fourth (T1) and seventh (T2) day treatment, new saliva samples were collected and colony counts (CFU...

Cocoa polyphenol pentamers significantly reduce biofilm formation and acid production by Streptococcus mutans and S. sanguinis. In the same way, trigonelline, caffeine and chlorogenic acid occurring in green and roasted coffee interfere with S. mutans adsorption to saliva-coated hydroxyapatite beads. Studies carried out on green, oolong and black tea indicate that tea polyphenols exert an anti-caries effect via an anti-microbial mode-of-action, and galloyl esters of (−)-epicatechin, (−)-epigallocatechin and (−)-gallocatechin show increasing antibacterial activities. The anti-cariogenic effects against α-haemolytic streptococci showed by polyphenols from cocoa, coffee, and tea suggest further studies to a possible application of these beverages in the prevention of pathogenesis of dental caries.

Trotter explored different territories of Libya, mainly Tripolitania, between 1912-1924, collecting plant specimens and the drugs most frequently sold in the markets. The Libyan herbarium currently includes over 2300 sheets of mounted and accessioned plants. The drugs, mostly acquired by Trotter from Tripolitanian markets, were identified and packed in 87 paper sheets or boxes. Trotter added ethnobotanical information for each species when available.

the Oratorio of Girolamini Library, in Naples, Italy. A close
look to the manuscript revealed that it was a latin translation
(end 12th-13th Century) of the Ishaq al Israili Liber de
diaetis particularibus, probably copied at Montecassino.
The manuscript is written in Gothic characters, however
there are still some substantial elements of a late Carolingian
minuscule of transition. The importance of the De
diaetis in the history of Western herbal medicine and dietetics
is discussed, with a focus on the role of barley as a
key plant of Ancient Greek therapy. A parchment sheet is
inserted in the manuscript and contains fragments of De
taxone and Liber medicinae ex animalibus pecoribus et bestiis
vel avibus. The position of the insertion seems not casual,
and has lead to the hypothesis that it could represent an integration
to the manuscript information on the importance
of some animals in human nutrition.
Napoli (PORUN), we found 170 specimens of unknown provenance mixed within the surviving Domenico
Cirillo’s herbarium (18th century). These 170 specimens were strikingly different from the rest and had never
been studied previously. From an initial close examination, we suggested that they may date back to the 16th
to 17th century, and likely have been part of Ferrante Imperato’s historical herbarium. To test our initial hypothesis,
we employed an empirical approach to assess the age and provenance of these specimens. First of all,
we assembled the available literature regarding the history of Italian botanical collections and collectors from
the 16th to the 18th century in the political context of those years. We integrated our historical reconstruction
with results obtained by radiocarbon analyses of the specimens and mounting paper, and watermark and paleographic
analyses. Our combined results are consistent with the hypothesis that these unknown specimens
may have been part of an 80 volumes herbarium that belonged to Ferrante Imperato, one of the earliest natural
historians of our times. Our integrated methodology is novel in the field of historical specimen research and
was critical in generating our final conclusions.
