"The floral tips of the plant species Lythrum salicaria L. represent a rich source of total polyphenols, among which with the largest share we mention tannins, and this is why this plant material has a standardized monograph in the European Pharmacopoeia 10.0th edition. According to the literature accessed so far, the plant material has antioxidant, anti-inflammatory, hemostatic, antibacterial and antifungal properties, along with modulatory action on carbohydrate metabolism. Powder microscopic examination is an important step in establishing the identity of the plant species used, highlighting elements specific to the aerial part such as spiral vessels of the stem, fragments of the spongy mesophyll with calcium oxalate clusters cells and anomocytic stomata. The application of the SeDeM method on dried plant extracts represents an innovative trend in pharmaceutical technology and contributes to the collection of data in a structured and standardized form. In this paper, the functions and applications of the SeDeM expert system are illustrated upon the freeze-dried extract of Lythri herba for the purpose of easier identification and standardization. Future applications may include obtaining chewable gums or tablets by direct compression."

"Nowadays we are witnessing an increased interest in phytotherapy and implicitly for herbal products that have lower side effects. One medicinal plant whose popularity has decreased significantly in recent years is Lythrum salicaria L., loosestrife, known in Romanian traditional medicine for its beneficial effects against gastrointestinal diseases. The aim of this study is to evaluate the biological activity of three different extracts (aqueous, alcoholic, acetonic) from the flower tips of Lythrum salicaria L. using the BSLA (Brine Shrimp Lethality Assay) test and the antimicrobial activity of the extracts on two reference bacterial strains which are important for the medical field (Staphylococcus aureus and Escherichia coli) through the diffusimetric method. We demonstrated the fact that the Lythri herba plant product extracts (aqueous, alcoholic, and acetonic) lack acute toxicity, as well as the moderate antibacterial effect on the Gram-positive reference strain, Staphylococcus aureus, thus highlighting the possibility of using the plant in biomedical applications."

"The Lythrum salicaria L. plant, from the Lythraceae family, has multiple beneficial effects on the human body, through pharmacological properties imprinted by its secondary metabolites, namely tannins. Chitosan-based biomedical materials are of increasing interest precisely due to the uniqueness of their properties, namely biocompatibility, nontoxicity, biodegradability, antimicrobial and antioxidant nature. The combination of chitosan with the plant extract aimed at obtaining new matrices, with clearly superior characteristics, compared to each material (chitosan and plant extract). This could be due to the presence of amino groups in the structure of chitosan, known to be active at a pH slightly acidic and which could be chemically bound to the phenolic groups of tannic acids (the predominant components of the plant extract). The study aimed to obtain for the first-time mixtures of different concentrations of aqueous solutions of Lythri herba plant extract with standard chitosan 1 % in lactic acid (1 %) solution, which allowed achieving compatible and stable membranes. Microscopic evaluation of the membranes were made, following the uniformity of the surfaces, the homogeneity, the distribution of chitosan relative to the extract, and their stability in PBS saline buffer. The behavior of these membranes gives us a perspective on their use in dentistry and pharmaceuticals. In addition, the current paper has shown the existence of chitosan in the composition of the obtained membranes and their ability to maintain constant hydration and flexibility over a certain period."
