In traditional herbal medicine the following notes apply to the species of this plant: The petals are applied externally as an astringent[240]. They are also made into a preserve and used as a tonic that helps to put on weight[240]. The buds (the report does not say if it is leaf or flower buds) are aperient, astringent, cardiac and tonic[240]. They are used for removing bile and cold humours[240]. The fruit of many members of this genus is a very rich source of vitamins and minerals, especially in vitamins A, C and E, flavanoids and other bio-active compounds. It is also a fairly good source of essential fatty acids, which is fairly unusual for a fruit.
