Evaluation of 28-day repeated doses oral toxicity of essential oil from Kiaersk leaves on various biological parameters in Swiss mice.

Only a small number of the many medicinally important species in the genus L. have had their safety assessed. , a plant native to Brazil, is reported to exert antinociceptive and anti-inflammatory effects; however, there are no apparent reports of long-term safety following administering of repeated doses.

Essential oil from leaves of Myrciaria floribunda (H. West ex Willd.) O. Berg has antinociceptive and anti-inflammatory potential.

Myrciaria floribunda is a plant that is distributed across different Brazilian biomes such as the Amazon, Caatinga, Cerrado, and Atlantic Forest, and it possesses antioxidant, antimicrobial, and anticancer properties. The antinociceptive and anti-inflammatory properties of the essential oil from M. floribunda leaves (MfEO) were examined in this study using mouse models.

Chemical composition, antinociceptive and anti-inflammatory effects in mice of the essential oil of Psidium cattleyanum Sabine leaves.

Ethnopharmacological Relevance: One of the native species of the genus most often mentioned by traditional people is Psidium cattleyanum Sabine, which is used mostly to treat disorders of the respiratory, genitourinary, and digestive systems. These symptoms are mainly treated by the decoction of the leaves. Additionally, there are gaps in the in vivo and toxicity investigations of this species.

Influence of Seasonal Variation on the Chemical Composition and Biological Activities of Essential Oil from Eugenia pohliana DC Leaves.

The purpose of this study was to analyses the influence of seasonal variation on the chemical composition and antimicrobial, antioxidant and cytotoxicity activities of the essential oil (EO) extracted from the leaves of Eugenia pohliana. Chemical characterization of the samples - by gas chromatography-mass spectrometry - found 35 and 38 components for summer and winter, respectively, of the EO from E. pohliana leaves, totaling 47 different compounds.
