   • Selon Jameson S (2023)

     Extrait Guava (Psidium guajava L.) tree (Myrtaceae family) bears fruit rich in vitamins, fiber, & other nutrients. Guava has been shown to exhibit a number of biological & pharmacological activities, such as antioxidant, anti-inflammatory, immunomodulatory, antimicrobial, antidiabetic, and anticancer properties.

   • Selon LOK B (2023)

     Extrait The fruits, leaves, & bark of the guava (Psidium guajava) tree have traditionally been used to treat a myriad of ailments, especially in the tropical and subtropical regions. The various parts of the plant have been shown to exhibit medicinal properties, such as antimicrobial, antioxidant, anti-inflammatory, & antidiabetic activities.

     Extrait 2023-Abstarct: The fruits, leaves, & bark of the guava (Psidium guajava) tree have traditionally been used to treat a myriad of ailments, especially in the tropical & subtropical regions. Lok B et al, The Anticancer Potential of Psidium guajava (Guava) Extracts, Life (Basel), 13(2):346.

   • Selon Beidokhti MN (2015)

     Extrait The ethanolic extracts were generally inactive against pancreatic α-amylase, & only bark extracts of Psidium guajava & Vangueria madagascariensis showed good activity with IC50 of 10.6 and 11.6 µg/mL, respectively. The aim of this study was to assess whether inhibition of α-glucosidase [1] & α-amylase [2] by ethanol extracts of 40 Madagascarian plants is the scientific rationale behind their traditional anti-diabetic use.

   • Selon Lin CY (2012)

     Extrait This study analyzed the content of phenolic acids & flavonoids in extracts of Psidium guajava fruit & examined the renal protective effects of guava aqueous extract (GAE) & ethanol extract (GEE) in diabetic mice. GAE or GEE intake at 2 % significantly reduced glucose & blood urea nitrogen levels, increased insulin level in plasma of diabetic mice (p < 0.05).

   • Selon Auteur (2015)

     Extrait Aqueous extract of Psidium guajava fruit was treated with 95% ethanol to collect the water-soluble polysaccharide precipitates. Therefore, the polysaccharide of PG possesses hepatoprotective activity & can be used as a dietary supplementation for protection of liver.

   • Selon Menezes FNDD (2023)

     Extrait This study evaluated whether by-products from industrial processing of acerola (Malpighia glabra L.; AB) & guava (Psidium guajava L.; GB) fruit may stimulate the growth and metabolism of probiotic Lactobacillus & Bifidobacterium & induce changes in human colonic microbiota.

   • Selon Al-Marakby K (2026)

     Extrait One of these fruits is guava (Psidium guajava), which is widely cultivated in humid & subtropical regions. They possess a diverse range of biological activities, including antioxidants, anti-flu, anti-cough, anti-inflammatory, hepatoprotective, antimicrobial, & antidiarrheal properties.

   • Selon Uboh FE (2010)

     Extrait This study considers the effects of aqueous extract of Psidium guajava leaves on the histology & biochemical indices of liver function as well as hematological indices in rats. Serum alanine aminotransferase (ALT), aspartate aminotransferase(AST), alkaline phosphatase (ALP), albumin & total protein levels, as well as the tissue histological assay are known to be useful in assessing the functional integrity of the liver.

   • Selon SAMBO N (2009)

     Extrait The effect of Psidium guajava extract on erythromycin-induced liver damage in albino rats was investigated using 30 normal rats grouped into six Group I & II served as the normal and treatment controls that were administered with normal saline and 100mg/kg body weight of erythromycin stearate daily for 14 days respectively. Histopathological investigation of the liver tissues revealed striking oedema & mild periportal mononuclear cell infiltration of hepatic cords in the liver of rats administered 100 mg/kg of erythromycin stearate & 300/450 mg/kg of PG extract.

   • Selon Lok B (2020)

     Extrait To evaluate the anti-angiogenic & anticancer activities of Psidium guajava leaf extracts against angiogenesis-dependent colorectal cancer. Conclusions: The ethanol extract of P guajava has potential in the treatment of colorectal cancer through the inhibition of angiogenesis.

   • Selon Lôk B (2019)

     Extrait As they are rich in phenols, flavonoids & carotenoids, it is speculated that extracts from guava leaves may possess antiangiogenic activity & in turn, contain anticancer activity on colorectal cancer through their inhibition of angiogenesis. Psidium guajava (Guava) leaves had been traditionally used as a treatment for various ailments in tropical & subtropical countries.

   • Selon LOK B (2023)
