Euonymus atropurpureus

Also known as arrow-wood, bitter ash, burning bush, indian arrow and spindle tree. Wahoo is a deciduous shrub found in some areas of North America. It grows up to 25 feet high, and has smooth branches. The leaves are elliptic and pointed, and have fine hairs underneath. Cymes of 7 or more purple flowers bloom on the bush during June. The fruit of the plant is scarlet in colour, and is a four-lobed capsule containing brown seeds.

The bark of the wahoo plant is cardiac, diuretic, expectorant, laxative and tonic. It was commonly used in the 19th century as a diuretic drug. Chest and lung congestion, indigestion and fever have all been treated with this plant, and it was once popular as a cardiac drug due to it's digitalis-like effect on the heart. The leaves and fruit of wahoo have been known to cause symptoms of poison such as nausea, cold sweat and prostration.
