Basil’s beta-caryophyllene can reduce inflammatory bowel disease risks.

4. Calming Benefits

Pets can get anxious or nervous in many instances that don't pose real danger. For instance, your dog can get anxious during travel or when they are in the presence of many people outdoors. In such instances, basil can act as a calming agent.

In fact, the herb is safer and better compared to most prescription medicines for anxiety. This explains why many certified calming dog supplements have some basil in them.
