Published articles of Psidium guineense Swartz.

Hot aqueous extract of  P. guineense  fruit perciarp  had  in-vitro  inhibitory  activity  against  Staphylococcus  aureus,  Escherichia  coli   and  Aspergillus  niger. Ethanol  extracts  from  the  peel  and  pulp  of   P. guineense  and its various factions exhibited antibacterial  activity  against   Streptococcus  mutans  strains. The antimicrobial activity of the  P. guineense  species may be  attributed  to  secondary  metabolites,  taninns, fl avonoids, terpenes and aldehydes present in the fruit.   Psidium  guineense   is  used  in  treating  diarrhoeas  in  Argentinean  traditional  medicine.  In  the  interior  of Brazil,  a  decoction  of  the  bark  or  roots  is employed  to  treat  urinary  diseases,  diarrhoea and dysentery and is considered to be diuretic.  In  Costa  Rica,  the  decoction  is  said  to  reduce varicose  veins  and  ulcers  on  the  legs.  A  leaf decoction  is  taken  to  relieve  colds  and bronchitis.

USES:  Bark:  Bark  is  boiled,  and  the  water  drunk  as  an  anti-diarrheal  by  the  Guyana  Patamona. Leaf: Leaves are boiled, and the water drunk as a treatment for coughing or as an anti-diarrheal, by the Guyana Patamona. Fruit: Juice of the young fruit is squeezed and used as an anti-dysenteric or for “bad-belly”, by the Guyana Patamona. [Medicinal Plants of the Guianas (Guyana, Surinam, French Guiana) ]
