Overview

Tronadora is a shrub with long sharp leaves and yellow trumpet-like flowers. It is used to make medicine. Medicine is usually made from the leaves and stems, although the roots and flowers are also sometimes used.

People use tronadora for diabetes and digestion problems. However, there is no good scientific evidence to support these uses.

Early research suggests that tronadora might have anti-inflammatory effects.
