Edibility and safety notes

The ripe purple-black berries (but/boot) are sweet and eaten fresh or dried; mountain people in northern Oman gather them every season and they are sold in local markets. Each fruit holds one hard seed, which is not eaten. No toxicity is reported for the fruit; no information was found on eating any other part. The leaves are reported to be eaten by grazing animals and the Omani field guide rates the tree good browse for goats and camels, but no study of its safety for livestock was found. The branches are spiny, so pick with care.
