- Dosing considerations for Oregano.
Oregano is used for respiratory tract disorders such as coughs, asthma, croup, and bronchitis. It is also used for gastrointestinal (GI) disorders such as heartburn and bloating. Other uses include treating menstrual cramps, rheumatoid arthritis, urinary tract disorders including urinary tract infections (UTIs), headaches, and heart conditions.
The oil of oregano is taken by mouth for intestinal parasites, allergies, sinus pain, arthritis, cold and flu, swine flu, earaches, and fatigue. It is applied to the skin for skin conditions including acne, athlete's foot, oily skin, dandruff, canker sores, warts, ringworm, rosacea, and psoriasis; as well as for insect and spider bites, gum disease, toothaches, muscle pain, and varicose veins. Oregano oil is also used topically as an insect repellent.
In foods and beverages, oregano is used as a culinary spice and a food preservative.
Possibly Effective for...
- High cholesterol. Clinical research shows that taking oregano after each meal for 3 months can reduce low-density lipoprotein (LDL or "bad") cholesterol and increase high-density lipoprotein (HDL or "good") cholesterol in people with high cholesterol. However, total cholesterol and triglyceride levels are not affected.
- Parasites in the intestines. Taking oil of oregano for 6 weeks can kill the parasites Blastocystis hominis, Entamoeba hartmanni, and Endolimax nana.
Insufficient Evidence to Rate Effectiveness for...
- Bleeding disorders (hemophilia). Early research suggests that oregano might not prevent bleeding after dental procedures in people with hemophilia.
- Wound healing. Early research suggests that applying an oregano extract to the skin twice daily for up to 14 days can improve skin color, stiffness, and thickness, but does not improve itching, pain, or scars, in people who have had portions of skin removed surgically.
- Repelling insects.
- Indigestion and bloating.
- Painful menstrual periods.
- Heart conditions.
- Other conditions.
Natural Medicines Comprehensive Database rates effectiveness based on scientific evidence according to the following scale: Effective, Likely Effective, Possibly Effective, Possibly Ineffective, Likely Ineffective, and Insufficient Evidence to Rate (detailed description of each of the ratings).
