Brief Introduction

Quercetin is a plant pigment (flavonoid). It is found in many plants and foods, such as red wine, onions, green tea, apples, berries, Ginkgo biloba, St. John’s wort, American elder, and others. Buckwheat tea has a large amount of quercetin. People use quercetin as a medicine.

Quercetin is used for treating conditions of the heart and blood vessels including “hardening of the arteries” (atherosclerosis), high cholesterol, heart disease, and circulation problems. It is also used for diabetes, cataracts, hay fever, peptic ulcer, schizophrenia, inflammation, asthma, gout, viral infections, chronic fatigue syndrome (CFS), preventing cancer, and for treating chronic infections of the prostate. Quercetin is also used to increase endurance and improve athletic performance.

Main Function

1.Quercetin may expel phlegm and arrest coughing, it can also be used as anti-asthmatic.

2. Quercetin has anticancer activity, inhibits PI3-kinase activity and slightly inhibits PIP Kinase activity, reduces cancer cell growth via type II estrogen receptors.

3.Quercetin may inhibit histamine release from basophils and mast cells.

4. Quercetin may control the spread of certain viruses within the body.

5, Quercetin may help reduce tissue destruction.

6.Quercetin may also be beneficial in the treatment of dysentery, gout, and psoriasis

Artificial biofilms establish the role of matrix interactions in staphylococcal biofilm assembly and disassembly. Elizabeth J. Stewart et al (2015), Scientific Reports https://dx.doi.org/10.1038/srep13081

We demonstrate that the microstructural and mechanical properties of bacterial biofilms can be created through colloidal self-assembly of cells and polymers, and thereby link the complex material properties of biofilms to well understood colloidal and polymeric behaviors. This finding is applied to soften and disassemble staphylococcal biofilms through pH changes. Bacterial biofilms are viscoelastic, structured communities of cells encapsulated in an extracellular polymeric substance (EPS) comprised of polysaccharides, proteins, and DNA. Although the identity and abundance of EPS macromolecules are known, how these matrix materials interact with themselves and bacterial cells to generate biofilm morphology and mechanics is not understood. Here, we find that the colloidal self-assembly of Staphylococcus epidermidis RP62A cells and polysaccharides into viscoelastic biofilms is driven by thermodynamic phase instability of EPS. pH conditions that induce phase instability of chitosan produce artificial S. epidermidis biofilms whose mechanics match natural S. epidermidis biofilms. Furthermore, pH-induced solubilization of the matrix triggers disassembly in both artificial and natural S. epidermidis biofilms. This pH-induced disassembly occurs in biofilms formed by five additional staphylococcal strains, including three clinical isolates. Our findings suggest that colloidal self-assembly of cells and matrix polymers produces biofilm viscoelasticity and that biofilm control strategies can exploit this mechanism.

Growing Your Own Stevia
(Excerpted from Stevia Rebaudiana: Nature’s Sweet Secret, Vital Health Publishing)
If you enjoy gardening, Stevia can be a rewarding herb to grow. While it’s not feasible for most of us to grow sugarcane or sorghum in our backyard, several Stevia plants will fit nicely into a small garden. Recipes utilizing Green Stevia Powder are now available, and the whole leaves add to the flavor of herbal teas.
Stevia rebaudiana is a tender perennial, native to semi-humid subtropical regions of Paraguay and Brazil. Wild plants occur on acid soils that are constantly moist, but not inundated, often near the edge of marshes or streams where the soil is sandy (Brandle et al., 1998). In the garden, too, Stevia doesn’t like to dry out, but standing water will encourage rot and disease. Stevia can be a successful garden plant in most climates with the use of a few simple techniques. Raised beds or hills prevent “wet feet,” while an organic mulch and frequent watering ensure a constant supply of moisture.
In North America, Stevia survives winters only in the warmest areas such as southern California, Florida, and Mexico. Research in Japan indicates a critical winter soil temperature of 32 F to 35 F (Sumida, 1980). Stevia is a weak perennial, so plants grown as perennials should be replaced every few years. In colder areas, Stevia is planted after the last frost and treated as an annual. Longer summer days found at higher latitudes favor leaf yield and Stevioside content (Shock, 1982).
Soil Preparation
While tolerant of most soil types, Stevia prefers a sandy loam or loam. Any well-drained soil that produces a good crop of vegetables should work fine. Incorporating organic matter is the best way to improve heavy, high clay soils. A rich compost made with leaves, grass, hay, kitchen waste, manure, and other organic residues will improve soil structure and supply nutrients. Finished compost may be tilled, disked, or spaded into the soil before planting or used as a mulch later on. A “green manure” crop the previous year such as oats, rye, or legumes will also improve heavy soils. Stevia occurs naturally on soils of pH 4 to 5, but thrives with soil pH as high as 7.5. However, Stevia does not tolerate saline soils
Como crescer Stevia rebaudiana Bertoni Planta
 Qualquer solo bem drenado, que produz uma boa colheita de legumes deve funcionar bem. Incorporando a matéria orgânica é a melhor maneira de melhorar pesados, solos de alta de argila. Um composto rico feito com folhas, grama, feno, restos de cozinha, esterco e outros resíduos orgânicos vai melhorar estrutura e fornecimento de nutrientes do solo. Composto final pode ser lavrada, disked ou spaded no solo antes de plantar ou usado como uma cobertura mais tarde. A “adubo verde” cortar ao ano anterior, como aveia, centeio, ou leguminosas também irá melhorar solos pesados. Stevia ocorre naturalmente em solos de pH de 4 a 5, mas vive com o pH do solo tão alto quanto 7,5. No entanto, Stevia não tolera solos salinos . Fosfato de rocha, farinha de ossos, e greensand oferecer uma ampla gama de minerais. Para a máxima disponibilidade de nutrientes, trabalhar adubos orgânicos no solo, alguns meses antes do plantio, ou misturar com adubo.
Come coltivare Stevia rebaudiana Bertoni piante
 Qualsiasi terreno ben drenato che produce un buon raccolto di ortaggi dovrebbe funzionare bene. Incorporando la materia organica è il modo migliore per migliorare pesanti, terreni argillosi alti. Un ricco compost fatto con foglie, erba, fieno, scarti di cucina, letame, ed altri residui organici migliorerà la struttura del suolo e la fornitura di sostanze nutritive. Compost finito può essere coltivato, disked, o vangato nel terreno prima di piantare o utilizzata come pacciamatura in seguito. A “sovescio” ritagliare l’anno precedente, come l’avena, segale, o legumi migliorerà anche terreni pesanti. Stevia verifica naturalmente su suoli di pH da 4 a 5, ma cresce con terreno pH alto come 7.5. Tuttavia, Stevia non tollera suoli salini.
Mentre un buon compost di solito soddisfa i requisiti nutrizionali, i sintomi di test suolo o vegetali possono avvisare l’utente di carenze. Mark Langan di Mulberry Creek Herbfarm raccomanda basso azoto o fertilizzanti organici. Eccesso di azoto favorisce la crescita rango di sapore poveri. Farina di ossa, farina di sangue, farina di semi di cotone, guano, o letame essiccato fornire azoto che viene rilasciato lentamente. Fosfato o farina di ossa forniscono fosforo. Greensand è una buona fonte di potassio. Fosfato, farina di ossa, e sabbia verde offrono una vasta gamma di tracce di minerali. Per la massima disponibilità di nutrienti, lavorare fertilizzanti organici nel suolo un paio di mesi prima di piantare, o mescolare con compost
