Brazilian Amazon Red Propolis: Leishmanicidal Activity and Chemical Composition of a New Variety of Red Propolis.

Leishmaniasis is caused by protozoans of the genus , and its treatment is highly toxic, leading to treatment discontinuation and the emergence of resistant strains. In this study, we assessed the leishmanicidal activity and chemical composition of red propolis collected from the Amazon-dominated region of northern Tocantins State, Brazil. The MTT assay was employed to determine the samples' activity against promastigotes and their cytotoxicity against RAW macrophages.

The Anti-Virulence Effect of against and .

In folk medicine, is used to treat skin diseases and mycoses in the Amazon region. We evaluated the anti- activity of the hydroalcoholic extract from the leaves of (EHVG). HPLC-PDA and FIA-ESI-IT-MS were used to chemically characterize EHVG.
