Edibility and safety notes

No reliable information was found on whether people can eat this plant or whether it is poisonous, so it should not be eaten. A whole-plant extract is recorded in the UAE as a traditional eye remedy; this is folk use, not a sign of safety. The Omani field guide records it as not grazed by livestock; no source was found on toxicity to animals.

This guide is a hobby project, not expert advice. Never eat a wild plant, or feed it to animals, on the strength of this page alone. Read the disclaimer
