Traditional Knowledge
Useful plant parts :
Leaf
Uses in traditional medicine :
- Porridge prepared from young leaves is taken in the morning to cure cough and throat infections
- Given to convalescing patients
- Used in the treatment of diarrhoea
Scientific Research
Chemical constituents:
Tropane alkaloid: calystegines from leaves; catechol oxidase was found in soluble and particulate fractions of plant
Bioactivity :
Methanol extract of fresh leaves: bronchospasmogenic; aqueous extract of fruit: inhibits edema, antioxidative; aqueous extract of plant: inhibits immunologic and non-immunologic stimulation mediated anaphylactic reactions and TNF- secretion from mast cells; calystegines: glycosidases inhibitors; phenolics rich extract of fruit: inhibitors of key enzymes relevant for type 2 diabetes and hypertension; flavonoids extracted from fruits: hypolipidaemic
Clinical:
Fruit infusion has reduced total and LDL cholesterol levels and apolipoprotein B levels in blood
Note :
Young fruits are used as a vegetable
