What Is CBD Oil?

CBD oil is extracted from hemp and infused into a carrier oil such as MCT or hemp seed oil. It contains cannabidiol (CBD)—a non-psychoactive compound with calming, anti-inflammatory, and balancing effects.

CBD oil does not cause a high.

How CBD Oil Works

CBD interacts with the endocannabinoid system (ECS), a regulatory network responsible for:

• Mood and stress levels
• Sleep quality
• Pain perception
• Immune and inflammatory responses

By supporting the ECS, CBD oil may promote:

• Reduced anxiety and daily stress
• Better, deeper sleep
• Lower inflammation
• Enhanced sense of balance and wellness
