forest, and dry valleys. The plant requires full sunlight and well-drained soil to grow. S. spectabilis can flourish in a variety of different soils from moist, clay, sand, loam, slightly alkaline, and acidic soils even in poor black cotton soils. However it has difficulties adapting to soils with high aerosol salt concentrations. There are no known diseases that affects the plant. Today the species can be found in tropical areas all around the world due to its invasive nature. Taxonomy and systematics Senna spectabilis was long placed in the genus Cassia, or in the non-monophyletic Cathartocarpus assemblage, or separated – together with its relative Senna peralteana – in Pseudocassia.

Cathartocarpus humboldtianus Loudon Cathartocarpus speciosus (DC.) G.Don Cathartocarpus trinitatis (DC.) G.Don Pseudocassia spectabilis (DC.) Britton & Rose In addition, one or two varieties of this species are recognized: var. excelsa (Schrad.) H.S.Irwin & Barneby with the synonyms: Cassia excelsa Schrad. (see also above) Cassia fastigiata Nees (Cassia fastigiata Vahl is a synonym of Senna surattensis (Burm. f.) H.S.Irwin & Barneby) var. micans (Nees) H.S.Irwin & Barneby – may belong into Senna macranthera (Collad.) H.S.Irwin & Barneby (= Cassia macranthera Collad.).

The plant can be used as a treatment for ringworm and skin diseases. After extracting a leaf on alcohol there was significant antifungal activity, which suggests it can be used with infections caused by Candida albicans. The plant is effective against food borne pathogen B. Senna spectabilis also produces several substances that we deem necessary for metabolism, in which they are also used as a medicine or pharmaceutical drug. Pharmaceuticals that can produce piperidine alkaloids, pentacyclic terpenoids, and anthraquinones. It is also used in both eastern and western
