Evaluating birch leaf tea as a functional herbal beverage: Beneficial impact on the urinary tract, and metabolism in human organism.

Herbal teas are considered as a potential constituent of novel functional beverages consumed daily. One of the commonly used herbal teas is silver birch (Betula pendula Roth) leaf infusion, traditionally used in urinary tract diseases. In this study, the potential of birch leaf infusion as a functional beverage, emphasizing its active ingredients' bioavailability, anti-inflammatory, and antiadhesive properties concerning urinary tract health, was investigated.

HPLC-DAD-MS fingerprints of phenolics of selected Polygonum taxa and their chemometric analysis.

Many Polygonaceae taxa such as Bistorta officinalis, Persicaria amphibia, Persicaria hydropiper, Persicaria lapathifolia, Persicaria maculosa, Persicaria mitis, Polygonum aviculare occur naturally in the entire territory of Poland and are also common in other European countries. Many of these species are also utilised as medicinal plants. In this manuscript we establish the phytochemical profiles of selected taxa from the Polygonaceae focusing on phenolics.

Phytotherapy of mood disorders in the light of microbiota-gut-brain axis.

Background: Clinical research in natural product-based psychopharmacology has revealed a variety of promising herbal medicines that may provide benefit in the treatment of mild mood disorders, however failed to unambiguously indicate pharmacologically active constituents. The emerging role of the microbiota-gut-brain axis opens new possibilities in the search for effective methods of treatment and prevention of mood disorders.

Purpose: Considering the clinically proven effectiveness juxtaposed with inconsistencies regarding the indication of active principles for many medicinal plants applied in the treatment of anxiety and depression, the aim of the review is to look at their therapeutic properties from the perspective of the microbiota-gut-brain axis.

The contribution of phenolics to the anti-inflammatory potential of the extract from Bolivian coriander (Porophyllum ruderale subsp. ruderale).

Porophyllum ruderale subsp. ruderale is a food product used for seasoning in Central and Southern America. The present research aimed to investigate the chemical composition of an extract prepared from aerial parts of P.

Antiadhesive activity of hydroethanolic extract from bean pods of Phaseolus vulgaris (common bean) against uropathogenic E. coli and permeability of its constituents through Caco-2 cells monolayer.

Ethnopharmacological Relevance: Phaseaoli pericarpium (bean pods) is a pharmacopeial plant material traditionally used as a diuretic and antidiabetic agents. Diuretic activity of pod extracts was reported first in 1608. Since then Phaseoli pericarpium tea figures in many textbooks as medicinal plant material used by patients.

Gut microbiota metabolism and the permeability of natural products contained in infusions from herb of European goldenrod Solidago virgaurea L.

Ethnopharmacological Relevance: Solidago virgaurea L. (also known as European goldenrod) is a pharmacopoeial plant material popularly used by patients in the form of an infusion. It was traditionally used in Europe and North America for the treatment of urinary tract conditions.

Characterization of herbal teas containing lime flowers - Tiliae flos by HPTLC method with chemometric analysis.

Linden trees are a source of food products called lime flowers (Tiliae flos), traditionally used in the form of infusion for the treatment of feverish colds and coughs. Lime flowers should include flowers of Tilia cordata Mill, T.x europaea L.

High molecular pyrogens present in plant extracts interfere with examinations of their immunomodulatory properties in vitro.

The widely accepted strategy to justify the use of medicinal plant extracts in diseases with inflammatory background is their examination on in vitro models using immune cells. It is also a key initial step of research for active principles, which could be then isolated and tested on more advanced models, becoming new pharmacologically active lead molecules. The crucial aspect which has not been so far addressed in this context, is the presence of pyrogens in plant preparations.

Ellagitannins Stimulate IPEC-J2 Cells Monolayer Formation and Inhibit Enteropathogenic Growth and Adhesion.

herb (LSH) was applied in diarrhea therapy since ancient times. Despite empirically referenced therapeutic effects, the bioactivity mechanisms and chemical constituents responsible for pharmacological activity remain not fully resolved. Taking into consideration the historical use of LSH in treatment of diarrhea in humans and farm animals, the aim of the study was to examine in vitro the influence of LSH and its -glycosylic ellagitannins on processes associated with maintaining intestinal epithelium integrity and enteropathogenic (EPEC) growth and adhesion.

Antibacterial and anti-inflammatory activity of bistort (Bistorta officinalis) aqueous extract and its major components. Justification of the usage of the medicinal plant material as a traditional topical agent.

Ethnopharmacological Relevance: Bistort rhizome (Bistorta officinalis) is a traditionally used plant material popular in Europe and Asia in the treatment of diarrhea and as a topical agent for skin conditions. It contains tannins mostly condensed flavan-3-ol derivatives. However, the in-depth phytochemical investigation of infusions from this plant materials is still lacking.

The influence of procyanidins isolated from small-leaved lime flowers (Tilia cordata Mill.) on human neutrophils.

Linden flower is a wildly used plant material among patients in the treatment of common cold symptoms and mucosa inflammations. However, the structure and bioactivity of flavan-3-ol derivatives present in infusions from flowers of Tilia cordata have not been studied so far. The aim of current study was to isolate and identify main procyanidins present in the flowers of small-leaved lime and to evaluate their influence on the inflammatory response of human neutrophils ex vivo.
