Primary Ingredient

Oil of Oregano

Mediterranean-Sourced, Ultra-High Carvacrol
Our oregano oil is sourced from wild Mediterranean oregano (Origanum vulgare) and concentrated to a powerful 20:1 ratio. Each serving delivers the equivalent of 6,000mg of raw herb, standardized for maximum carvacrol content—the compound responsible for oregano's antioxidant and immune-supporting properties. Unlike cheap oregano supplements that use low-potency extracts or marjoram substitutes, we use only genuine Origanum vulgare with verified carvacrol levels. The difference? Real results you can feel.

Carvacrol, Oregano's Active Compound

Carvacrol is the compound oregano is best known for. It is one of the most-studied plant actives for supporting your body's natural defenses and everyday immune health.

Gut Microbiome Support

Oregano oil supports a balanced gut environment and healthy digestion, part of why it has been a staple of Mediterranean wellness for centuries.*

Potent Antioxidant Protection

Carvacrol provides antioxidant support, helping protect against everyday oxidative stress.*

Seasonal Support

Oregano has a long history of traditional use through the change of seasons. It is here to support your body's natural defenses year round.*

Black Seed Oil

Ancient Wisdom Meets Modern Science
Nigella sativa, commonly known as black seed or black cumin, has been called 'the seed of blessing' for over 2,000 years. Referenced in ancient texts and used across cultures from Egypt to India, this powerful seed has earned its legendary reputation. Our cold-pressed black seed oil is rich in thymoquinone—a potent compound studied in over 900 peer-reviewed papers for its remarkable effects on immunity, inflammation, and cellular health. It works synergistically with oregano oil to create a formula greater than the sum of its parts.

Everyday Immune Support

Thymoquinone is black seed oil's signature active. It is here to help support the body's natural defenses through everyday challenges.*

Healthy Inflammatory Response

Thymoquinone is included to support the body's normal inflammatory response and to add antioxidant support alongside oregano's carvacrol.*

Synergistic Enhancement

When combined with oregano oil, black seed oil amplifies overall effectiveness. The compounds work together through complementary mechanisms of action.

2,000+ Years of Traditional Use

Called 'the seed of blessing' in ancient texts, black seed has been used across cultures for millennia. Modern science is now validating what traditional healers knew all along.
