echinacea purpurea/抗真菌藥

This study demonstrated that plant extracts containing acetylenic isobutylamides and polyacetylenes, previously reported as occurring in Echinacea, have phototoxic antimicrobial activity against fungi, including clinically relevant pathogenic fungi. Results show that hexane extracts of Echinacea

Background. Recurrent vulvovaginal candidiasis (RVC) is an increasing challenge in clinical practice. Objective. The purpose of this study was to reduce the episodes of RVC through the intake of fluconazole 200 mg/dose with a personalized regimen at growing administration intervals with a probiotic.

In addition to widespread use in reducing the symptoms of colds and flu, Echinacea is traditionally employed to treat fungal and bacterial infections. However, to date the mechanism of antimicrobial activity of Echinacea extracts remains unclear. We utilized a set of ∼4,600 viable gene

Cichoric acid and Dodeca 2E, 4E, 8Z, 10E/Z-tetraenoic acid isobutylamide (alkamides 8, 9) are described as immunomodulating active components of Echinacea. We quantified both substances in 25 Echinacea-containing remedies customary in trade. Concerning both active components, we found highly

BACKGROUND Gastrointestinal and respiratory diseases in calves and piglets lead to significant economic losses in livestock husbandry. A high morbidity has been reported for diarrhea (calves ≤ 35%; piglets ≤ 50%) and for respiratory diseases (calves ≤ 80%; piglets ≤ 40%). Despite a highly diverse

The endophytic fungal community associated with the ethnomedicinal plant Echinacea purpurea was investigated as well as its potential for providing antifungal compounds against plant pathogenic fungi. A total of 233 endophytic fungal isolates were obtained and classified into 42 different taxa of 16

OBJECTIVE A large body of evidence has confirmed a multitude of health benefits of plant products and their derived formulations. Echinacea purpurea (L.) Moench is a good example, widely used due to its therapeutic properties. In the present study, the chemical composition of the different samples

OBJECTIVE We recently showed that daily dietary administration of Echinacea purpurea root extract to normal mice for as little as 1 week resulted in significant elevations of natural-killer (NK) cells (immune cells that are cytolytic to virus-containing cells and many tumor cells). Such boosting of

Chemiluminescence was used as an indicator for phagocytic activity of granulocytes induced by zymosan in whole blood. Luminol was used to amplify the luminescence measured. Methods and conditions of the trial were varied and the dependence on the methods applied became evident. The effects of

BACKGROUND When directly exposed to various echinacea fractions, human leukocytes ex vivo are strongly stimulated to proliferate and to produce immunostimulation and inflammatory cytokines. A comparison of fractions containing lipoidal small molecules and high-molecular-weight water-soluble

Single oral or intravenous doses of the expressed juice of Echinacea purpurea (EP) proved virtually non-toxic to rats and mice. After 4 weeks of oral administration in doses amounting to many times the human therapeutic dose laboratory tests and necropsy findings gave no evidence of any toxic

Extracts of Viscum album (Plenosol) and Echinacea purpurea (Echinacin) are used clinically for their non-specific action on cell-mediated immunity. In vitro we could prove that these two extracts have a stimulating effect on the production of lymphokines by lymphocytes and in the transformation

Echinacea preparations are one of the best selling herbal medicinal products with a well established therapeutic use in the prophylaxis of upper respiratory tract infections. Their consumption is increasing, but information about their ability to inhibit cytochrome P450 enzymes (CYP) is fragmentary.
