Edible Uses

Edible Parts: Flowers Fruit Edible Uses: Tea Fruit - raw or cooked[105, 161, 257]. A bitter flavour[183]. The fruit is quite nutritious, having a relatively high fat and protein as well as carbohydrate content[212]. The fruit can be dried prior to use, it will then lose some of its rank taste[183]. The fruit is about 5mm in diameter and is borne in large clusters making it easy to harvest[200]. Some caution is advised, see the notes above on toxicity. Flowers - raw or cooked. The root is made into a tea-like beverage[105, 161, 183].

Medicinal Uses

Diuretic Purgative The bark and the leaves are used as a diuretic and purgative[212]. The blossoms have been used in the treatment of measles[257].

Known Hazards

Although no specific mention has been seen for this species, the leaves and stems of some, if not all, members of this genus are poisonous[9, 76]. The fruit of many species (although no records have been seen for this species) has been known to cause stomach upsets to some people. Any toxin the fruit might contain is liable to be of very low toxicity and is destroyed when the fruit is cooked[65, 76]. NC State University have noted Cyanogenic glycoside and alkaloids can cause low toxity if eaten.
