Edible Uses

Edible Parts: Flowers Edible Uses: Gum Flowers - cooked[144]. Rich in pollen, they are often used in fritters. A gum that exudes naturally from the trunk is edible and is used as a substitute for Gum Arabic in making jellies etc[46, 105, 177]. It is insoluble in water[153] and is of low quality[64]. Larger quantities can be obtained by tapping the trunk[64]. Some species produce a gum that is dark and is liable to be astringent and distasteful, but others produce a light gum and this is sweet and pleasant. It can be sucked like candy or soaked in water to make a jelly.[193]. The gum can be warmed when it becomes soft and chewable[193].

Medicinal Uses
