Bromeliaceae

Common Names:
Annasi (S)
Anassappalam, Annasa (T)
Pineapple (E)
Ama, Kautukasanjaka, Paravati (Sa)

Traditional Knowledge

Useful plant parts :
Leaf and young fruit

Uses in traditional medicine :

  • Juice of leaves is used in high doses as a purgative
  • Infusion of leaves is diuretic, diaphoretic, aperient, refrigerant and digestive
  • Juice of young fruits is a vermifuge and used in violent purging, flatulence, distension of abdomen, uterine contractions, jaundice and diarrhoea
  • Oral intake of young fruits acts as an abortifacient

Scientific Research

Chemical constituents:

Proteolytic enzyme mixture: bromelain, lactone: 4-hydroxy-2, 5-dimethyl-3( 2H )-furanone butyric acid esters and other esters, phenolic compounds: S-sinapyl-L-cysteine, N-L-γ-glutamyl-S-sinapyl-L-cysteine, and S-sinapylglutathione from fruits

Bioactivity :

Bromelain: interferes with growth of malignant cells, inhibits platelet aggregation, fibrinolytic, anti-inflammatory, skin debridement properties; ethanol extract of leaves: antidiabetic, antidyslipidaemic,  antioxidative

Clinical:

Bromelain may be effective in ameliorating physical symptoms and improving general well-being in healthy adults suffering from mild knee pain

Note :

Ripe fruits are edible
