Two ancient herbs. Thousands of years of trust.
Oil of oregano and black seed oil have been used across cultures for centuries, studied by modern science, and trusted by generations long before the supplement industry existed.
We chose these two because they've stood the test of time — and because we could trace exactly where they come from and why they've earned their place in traditional medicine.
“Three of the most-studied herbs in traditional medicine — the same ones our great-grandmothers used, backed by modern research.”— Jonathan, Resilia CEO
Oil of Oregano & Carvacrol
Oregano has been part of traditional wellness in Mediterranean cultures for centuries, but its reputation isn't just historical. The active compounds in oil of oregano, primarily carvacrol and thymol, have been the subject of hundreds of peer-reviewed studies.
Carvacrol and thymol are two powerful compounds studied for their role in supporting the body's defenses, and oregano oil is widely used to support immune health.†
For gut health specifically, the evidence is meaningful. Oregano oil has been researched in gut-rebalancing protocols and in relation to unwanted bacterial overgrowth.
In one small study, oregano oil was included as part of a treatment approach for small intestinal bacterial overgrowth; after ten weeks, nearly half of participants showed improvement. Individual results may vary.

Your grandmother didn't need a wellness trend to tell her these worked.
Oil of oregano and black seed oil have been trusted across cultures for thousands of years. Not because of a study, a subscription box, or a social media post. Because they worked then, and they remain part of wellness traditions now.
Black Seed Oil and its History
Used for over 3,000 years. Still earning its reputation.
Black seed oil is extracted from the seeds of Nigella sativa, a flowering plant native to the Mediterranean and Western Asia. It has been used for over 3,000 years and is referenced in historical texts across Middle Eastern, African, and South Asian healing traditions.
Modern research has begun to catch up with that tradition. Black seed oil contains thymoquinone, a compound researched for antioxidant and immunomodulatory effects.†
Research has examined black seed oil in relation to natural killer cell activity, T-cell function, and cytokine balance. In plain terms, researchers are studying how it may help the immune system respond appropriately rather than simply stimulating it in one direction.
We include it alongside oregano oil because the two ingredients address complementary aspects of immune and gut wellness.†
