What is antimicrobial activity of medicinal plants?
Antimicrobial Activity of Medicinal Plants Correlates with the Proportion of Antagonistic Endophytes. Medicinal plants are known to harbor potential endophytic microbes, due to their bioactive compounds.
How effective are herbal antimicrobials?
Herbal drugs are more effective than conventional antimicrobials: Studies have revealed that barring a few (Carvacrol from Oregano oil, thyme oil, ajowan oil, cinnamaldehyde in cinnamon and cinnamon oil) they are less effective than common antibiotics1-4.
What are antimicrobial plants?
Extracts of various herbs and spices (for example sage, thyme, clove, garlic) have been shown to have antimicrobial activity. Some mosses and lichens also contain antimicrobial compounds.
Which medicinal plant has high antibacterial properties?
Among the three medicinal plants, B. ciliata extracts displayed potential activity against bacterial pathogens. Cold water extract of Bergenia ciliate showed the highest activity against B. subtilis, which is comparable with a zone of inhibition exhibited by ceftriaxone and erythromycin.
When did antimicrobial activity of medicinal plants increase?
When we reviewed the number of articles published on the antimicrobial activity of medicinal plants in PubMed during the period between 1966 and 1994, we found 115; however, in the following decade between 1995 and 2004, this number more than doubled to 307. In the studies themselves one finds a wide range of criteria.
Are there any medicinal plants that are antimicrobial?
In the present paper, we analyze the past, present and future of medicinal plants, both as potential antimicrobial crude drugs as well as a source for natural compounds that act as new anti-infection agents. In the past few decades, the search for new anti-infection agents has occupied many research groups in the field of ethnopharmacology.
Which is plant extract has the most antimicrobial activity?
Plant extracts of H. perforatum exhibited a remarkable activity against bacterial and fungal pathogens, whereas extracts of Z. capitata did not exhibit any potential antimicrobial activity.
Where are most antimicrobial compounds found in nature?
They are derived from prokaryotic bacteria, eukaryotic microorganisms, plants and various animal organisms. Microbial and plant products occupy the major part of the antimicrobial compounds discovered until now . Plants and other natural sources can provide a huge range of complex and structurally diverse compounds.
