A Review on: Morphological, Phytochemical and Medical Important of Some Wild Euphorbiaceae Poisonous Plants

The plants are very important for living organisms, there would be no life on earth if plants did not exist. Furthermore, when animals or humans consume many plants, they can have negative consequences. Plant toxicity is associated with a multitude of chemical toxins such as alkaloids, glycosides, proteins, and amino acids. There are numerous examples of poisonous species present in different families, one of them Euphorbiaceae. Euphorbiaceae is one of the four largest cosmopolitan families of flowering plants with 313 genera and around 8100, species. Morphological, phytochemical properties and medical uses for 11 wild species of Euphorbiaceae growing in Saudi Arabia were collected in this paper. Two species (Euphorbia fractiflexa and Jatropha glauca) don’t have data for its chemical and medical properties and need a lot of study. For the species growing on the Saudi Arabia, all studied species need further study except for Euphorbia granulata and Ricinus communis.
