Overview
•Oregano extract at high equivalent doses (6,000 mg) may cause gastrointestinal upset, heartburn, or allergic reactions in sensitive individuals.
•Thymoquinone from black seed oil is generally well-tolerated at 200 mg but can lower blood pressure or blood sugar, potentially interacting with antihypertensive or antidiabetic drugs.
•Long-term daily use of concentrated oregano oil extracts is not recommended due to potential liver or kidney strain at high doses.
•Not evaluated by FDA; claims for blood pressure, blood flow, and heart vitality lack strong direct clinical evidence for this exact formulation.
