West African Laburnum, scientifically known as Cassia sieberiana, is an ornamental tree native to West African countries such as Ghana, Guinea, Ivory Coast, Liberia, and Sierra Leone. This tree thrives in full sun and can adapt to various soil types, including light (sandy), medium, and heavy (clay). Standing up to 15 meters tall, it is known for its distinctive yellow pea-like flowers, which create a striking display during spring. The leaves and stems of the West African Laburnum are edible and can be consumed after cooking, although raw consumption is not recommended due to potential toxicity concerns. In traditional West African herbal medicine, the tree is used for digestive issues, such as bloating and indigestion. A decoction of the leaves or stems is commonly prepared to support gastrointestinal health. Additionally, the plant has been traditionally used for pest control and as a natural remedy for dental issues, such as teeth problems. This tree is hardy in zones 10-12 and is drought-tolerant but can also grow in moist conditions. It is an adaptable and ornamental addition to gardens and landscapes, providing both aesthetic value and potential health benefits when used appropriately.

The mechanism by which Cassia sieberiana supports digestion is not fully characterised but may involve compounds that help regulate gut motility and reduce inflammation in the digestive tract.
