According to the Global Biodiversity Information Facility (n.d), Senecio asirensis has the following classification.

Kingdom Plantae
Phylum Tracheophyta
      Class Magnoliopsida
         Order Asterales
               Family Asteraceae

The capitulum is discoid or radiate, usually stalked, often forms corymbose cymes, involucre generally with a single row of phyllaries subtended by small calyculus of much smaller bracts, phyllaries are free with membranous margin.

(Senecio L, n.d).Different authors have put forward the different types of traditional usages of Senecio asirensis, and according to Sher and Alyemeni (2011), it belongs to one of the pharmaceutically essential plants used in the conventional system of Arab system of medicine. The extracts of this plant were utilized for the treatment of livestock ailments at an early age.

Besides, there has been extensive use of essential oils form different medicinal plants, including Senecio asirensis (Srivastava et al., 2019). Authors shave developed and perfected the process of extraction of different types of phytochemicals from Senecio sp. significant focus has been on the pyrrolizidine alkaloids (PA) and its implications in toxicity. The pyrrolizidine alkaloids are toxic to the herbivores, and the plants produce these alkaloids as a strategy against herbivory. The tests indicated very high PA concentrations and diversity amounting to 57 compounds, including the highly toxic 1,2-unsaturated PAs (Castells et al., 2014).

Different workers have highlighted the aspect of plant products as active botanical compounds with pharmacological as well as other properties, and research has authenticated numerous applications in almost all spheres like anti-microbial, anti-fungal, insecticide, repellent, etc. ( Hou et al. 2014, Souza et al. 2015), etc. However, there are also reports of health aspects of the use of Senecio asirensis extract where human health, as well as critical toxicity, has been reported in case of cattle (Panziera et al.,2018); Siedle et al.
