   • Selon Usman RM (2019)

     Extrait ether extract was used to evaluate the anti-inflammatory & analgesic effects in carrageenan-induced paw edema and anti analgesic activity effect in hot plate method. venusta are used as a general tonic & a treatment for diarrhea, vitiligo, cough, & common infections & inflammatory diseases of the respiratory system.

   • Selon --Veloso CC (2012)

     Extrait venusta hydroethanolic extract (PvHE) was used to evaluate the anti-inflammatory & analgesic effects in carrageenan-induced paw edema, peritonitis induced by lipopolysaccharide, acetic acid-induced writhing & formalin-induced paw-licking tests in Swiss male mice. venusta are used as a general tonic & a treatment for diarrhea, vitiligo, cough & common infections & inflammatory diseases of the respiratory system.

   • Selon de Carvalho Veloso C (2014)

     Extrait Pyrostegia venusta is used in traditional Brazilian medicine as a general tonic to treat any inflammatory disease. Accordingly, we investigated the effects of hydroethanolic extract of PV flowers (PvHE) supplementation for the treatment of inflammatory & metabolic dysfunction induced by high-refined-carbohydrate (HC) diet Material & methods The BALB/c mice were fed chow or HC diet for 8 weeks.

   • Selon Thales D (2014)

     Extrait venusta had CV values that were better than the commercial anti-inflammatory, which showed CV values below the negative control. Cell viability (CV) assays were done using macrophage RAW 264.7 cell lines and compared to four commercial anti-inflammatories (acetylsalicylic acid, Indometacina, Betametasona, and Piroxicam).

   • Selon Moreira CG (2015)

     Extrait venusta were evaluated in Swiss mice on edema model induced by croton oil, and further the N-acetyl-b-d-glucosaminidase (NAG) activity, cell infiltration & cytokine & reactive species oxygen (ROS) levels. venusta have significant antiinflammatory & Hyperpigmentant effects, demonstrating different topical and systemic effects through two animal models.

   • Selon Silva RMG (2012)

     Extrait This study aimed to investigate the antitumor & cytotoxicity activities of Kielmeyera coriacea & Pyrostegia venusta extracts. venusta showed 25.82 ± 5.15, 38.40 ± 8.28, 15.75 ± 4.44 & 13.38 ± 7.92, with their concentrations for the antitumor bioassay, and the positive control showed 25.80 ± 6.14.

   • Selon Bhat M (2022)

     Extrait The current investigation was aimed to biologically synthesize silver nanoparticles utilizing Pyrostegia venusta leaf aqueous extract. The antimicrobial activity was done against bacterial & fungal pathogens like Enterococcus faecalis, Escherichia coli, Candida albicans & Candida glabrata and finally subjected to anticancer activity & cell apoptotic pathway assessment against African green monkey kidney (COS-7) cell line.

   • Selon Zari S (2015)

     Extrait Pyrostegia venusta (Ker Gawl.) Miers is a plant species of the family Bignoniaceae, which is originally endemic to Brazil. This study reviews the published literature on wound healing, Hyperpigmentant & antitumor activity of P.

   • Selon Figueiredo CR (2014)

     Extrait Pyrostegia venusta heptane extract containing saturated aliphatic hydrocarbons induces apoptosis on B16F10-Nex2 melanoma cells & displays antitumor activity in vivo.

   • Selon Moreira CG (2015)

     Extrait Leaves of Pyrostegia venusta are popularly used to treat vitiligo; however, none in vivo study showed its ability. venusta either by gavage (300 mg/Kg) or topically (10%) increased epidermal melanin level (116.5 ± 13% & 100 ± 16.9%, respectively), diminished dermal depigmentation (36.0 ± 6.7% & 38.2 ± 6.2%, respectively), as well as tissue TNF-α levels (68.2 ± 11.6% & 99.2 ± 12.1%, respectively) & cell infiltration (basal levels and 94.3 ± 9.17%, respectively).
