When should you take oregano oil with black seed oil?
With a meal, at whatever time you'll remember. There's no proven best time. Many people choose breakfast for routine; others prefer dinner. If you take the serving in two parts, split it between morning and evening meals.
With food or on an empty stomach?
With food is best for most people. Oregano oil can cause heartburn or stomach upset on an empty stomach, and black seed oil can cause burping with a herbal aftertaste. A meal helps with both.[1]
