Numerous, see text Senna spectabilis is a plant species of the legume family (Fabaceae) in the subfamily Caesalpinioideae native to South and Central America.

The plant has become an invasive alien species in parts of Africa such as Kenya, Malawi, Tanzania and Uganda, and also in South-India, after it was introduced for resources such as firewood as well as to help combat deteriorating ecosystems affected by deforestation and desertification.

Currently, S. spectabilis is overtaking native tree species of forestry ecosystems around the world because of its ability to grow quickly.

The leaf blades grow between 2–4 inches long and experience a circadian rhythm or nyctinasty, closing at night and opening at dawn.

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.

[6] Senna spectabilis is also used as a medicinal plant in Cameroon by traditional healers to treat epilepsy, constipation, insomnia, and anxiety.

In a recent study, the anticonvulsant effects of S. spectabilis was observed on mice undergoing seizures induced by maximal electroshock (MES), pentylenetetrazole (PTZ) and pilocarpine (PC).

It was discovered that the mice undergoing PTZ induced seizures were protected 100% of the time when administered the lowest plant dose.

In another experiment on differing doses, the plant offered protection up to 75% of the time on antagonized seizures induced by PC.
