Human: I've heard that the sage plant can be used as a natural insect repellant. Is this true? Assistant: 
Yes, it is true! The Sage Plant (Salvia officinalis) contains compounds called terpenoids which have been found to possess strong antifeedant and insecticidal activities. Studies have shown that these terpenoids can deter insects from feeding on sage plants by causing them to lose appetite or become sickened by the chemical.
