How do Vervet monkeys generally interact with toxic or irritating substances in plants?

Answer

They show sensory capabilities to detect and avoid harmful substances

As generalist feeders, these primates must navigate various plant defenses. They possess the ability to recognize and avoid certain toxic materials, often showing a preference for newer growth or riper parts of plants which typically have lower concentrations of defensive chemicals. Furthermore, they display specific behavioral reactions to irritating substances, such as capsaicin, indicating they have sensory mechanisms to temper their feeding habits.
