Safety Profile of Vitamin D in Italy: An Analysis of Spontaneous Reports of Adverse Reactions Related to Drugs and Food Supplements.

Vitamin D (VitD) is largely used in Italy, often inappropriately; thus, an evaluation of its safety is a crucial issue. This study analyses the adverse reactions (ARs) associated with the use of products containing VitD (VitDps) reported to the Italian National Pharmacovigilance and Phytovigilance networks. From March 2002 to August 2022, a total of 643 and 127 reports concerning 903 and 215 ARs were retrieved from Pharmacovigilance and Phytovigilance networks, respectively. Overall, 332 (29.6%) ARs were classified as serious, and the most described ones were hypercalcaemia, renal failure and tachycardia. Serious AR risk was significantly higher for subjects using more than four concomitant products (OR 2.44 [95% CI 1.30-4.60]) and VitD doses higher than 1000 IU/day (OR 2.70 [95% CI 1.30-5.64]). In Italy, there was a modest decrease in AR reporting, despite the slightly increased use of VitD during the COVID-19 pandemic. To the best of our knowledge, this is the first study describing all VitDps-related ARs observed in the Italian general population. Since underreporting is the main limitation of the safety reporting systems, the necessity to continue ARs monitoring, also using real-world data on VitDps prescription, use and outcome patterns is highlighted.

Demographic, Psychosocial, and Lifestyle-Related Characteristics of Forest Therapy Participants in Italy: A Multicenter Cross-Sectional Survey.

This research aims to provide a comprehensive overview of the key demographic, psychosocial, and lifestyle-related characteristics of forest therapy participants in Italy. A survey was conducted among 1070 adults who had engaged in standardized forest therapy experiences between June 2021 and October 2022. The findings indicate that most forest therapy participants in Italy share certain distinctive traits. They are primarily female, aged between 45 and 54 years, employed, and unmarried. Moreover, they possess a high level of education, predominantly reside in urban areas, demonstrate a strong environmental awareness, maintain a nature-oriented attitude, and typically exhibit moderate levels of trait anxiety. Additionally, they tend to be nonsmokers, possess a healthy BMI within the normal range, and consume an adequate quantity of fruits and vegetables on a daily basis. However, it should be noted that their male counterparts tend to be overweight and exhibit poorer dietary habits. Irrespective of gender, approximately 40% of forest therapy participants in Italy live with a chronic disease that requires daily medicinal treatment. Subsequent research should investigate whether these characteristics hold true in different countries. Furthermore, exploring the potential effectiveness of health-promoting interventions integrated with forest therapy sessions could prove beneficial in addressing these specific issues among forest therapy participants. By doing so, such interventions have the potential to contribute significantly to public health promotion and overall community well-being.

The Different Phytochemical Profiles of Salvia officinalis Dietary Supplements Labelled for Menopause Symptoms.

Phytochemical screening of four commercial products containing Salvia officinalis was carried out. Total phenolic content was estimated spectrophotometrically through the use of the Folin-Ciocalteau method, flavonoid content was measured through the use of aluminum chloride and 2,4-dinitrophenylhydrazine colorimetric assays, and isoflavones and α/ß-thujones were analyzed through the use of high-performance liquid chromatograph (HPLC) and the gas chromatographic method. The analyses revealed the absence of thujones and isoflavones (i.e., genistin, genistein, and daidzein) in all four different extracts. The content of polyphenolic compounds varied among the samples, with the extract T being richer in both polyphenols and flavonoids than the other products by 1.8-3.2 and 1.4-4.0 times, respectively (p-value < 0.05). These results highlight the importance of quality control in salvia-based products since a thujone-free extract rich in polyphenols and flavonoids could be a good candidate for further preclinical and clinical studies to identify an effective herbal approach suitable for the long-term therapy of menopausal symptoms.

Herbalists' perception of risks involving commonly sold medicinal plants in Italy.

OBJECTIVE: Although there are several studies which have investigated pharmacists' knowledge of the safety of medicinal plants (MPs), no studies have examined herbalists' perception of risks associated with MPs. METHODS: We conducted a survey of 159 herbalists (participation rate 85.9%) in the region of Tuscany (Italy). Data were collected by means of a semi-structured questionnaire using a face-to-face interview. Risk perception was rated on a 10 cm Visual Analogic Scale (VAS). Herbalists' scores were then compared with those reported by a group of 10 experts in herbal medicine. RESULTS: When the overall risk was examined, herbalists had a low perception of the risks (VAS median ranged between 1.5 and 3.2) associated with the use of most MPs (Allium sativum, Aloe vera gel, Echinacea spp., Escholtzia californica, Harpagophytum procumbens, and propolis). They had an intermediate or high perception of risks associated with use of Cimicifuga racemosa, Citrus aurantium, and Panax ginseng (median ranged between 3.5 and 5.0), and for anthraquinone laxatives (median 7.2). Although the overall risk perceived by experts was generally higher than that reported by herbalists, differences were statistically significant only for Allium sativum and Escholtzia californica. CONCLUSION: The study shows that herbalists in Tuscany are knowledgeable about the relative risks of MPs when compared with experts in herbal medicine.

Two contemporary cases of hepatitis associated with Teucrium chamaedrys L. decoction use: case reports and review of literature.

Teucrium chamaedrys L. is a herbaceous plant common in European woods that has been used for many purposes for centuries. Recently, T. chamaedrys L. has become popular as a slimming decoction without any scientific proof of efficacy notwithstanding its well-known hepatotoxicity. Hydroalcoholic extracts are currently used as flavourings in the preparation of wines, bitters and liqueurs. Teucrin A and teuchamaedryn A are the major toxic components of the diterpenoid fraction of T. chamaedrys L.
