Waltheria viscosissima
Waltheria viscosissima · Accepted scientific name
Scientific literature: Very Sparse (0 studies) · ★☆☆☆☆
Waltheria viscosissima is a resilient shrub native to the tropical regions of the Caribbean and coastal areas. While it is often studied for its various medicinal properties, its physiological effects on the cardiovascular system must be approached with caution. Specifically, certain compounds within the plant may contribute to medical complications such as bradycardia. Furthermore, the consumption of this species can potentially lead to a dangerous drop in blood pressure, known as hypotension. Understanding these risks is essential for anyone exploring the botanical applications of this plant.

Biological Activities
Compounds
Conditions
Waltheria viscosissima induces significant dose-dependent hypotension and bradycardia in normotensive rats. The hydrobutanol extract of this plant is also capable of inducing second and third degree sinoatrial and atrioventricular blockade. Furthermore, the extract demonstrates the ability to antagonize the contractile effects of noradrenaline in isolated rat aortic rings. These observed cardiovascular actions are likely mediated through the stimulation of cardiac and endothelial muscarinic receptors. Overall, the plant's hydrobutanol phase exerts these specific effects on heart rate, blood pressure, and vascular contraction.
