The field of medicine and health
Antioxidant and anti-aging
Hydroxytyrosol and olivine can lower the risk of oxidative stress-related diseases (e.g., Alzheimer's and Parkinson's) and slow cellular aging.
Application:* Used in health supplements (soft capsules, tablets) or added to functional foods.
Cardiovascular protection
Mechanism: Regulates blood lipids by reducing LDL-C ("bad cholesterol") and increasing HDL-C ("good cholesterol"), inhibiting platelet aggregation, and improving vascular elasticity.
Research: Clinical studies indicate that olive polyphenols reduce hypertension and coronary heart disease incidence.
Anti-inflammatory and immune regulation
Oleuropein inhibits respiratory tract inflammation (e.g., pharyngitis, bronchitis) and alleviates allergic reactions.
*Usage:* Found in cough syrups, throat lozenges, or immune-boosting health products.
Antibacterial and antiviral
It effectively inhibits bacteria like Escherichia coli, Staphylococcus aureus, as well as influenza virus and herpes virus; suitable for use as an external disinfectant or natural preservative.
2. Food industry
Natural antioxidant
Can replace synthetic antioxidants (e.g., BHA, BHT) in oils, meats, baked goods to extend shelf life.
Case: Olive oil extract is commonly used for antioxidant preservation in fried or ready-to-eat foods.
Added to beverages/dairy products with health claims (e.g., "rich in polyphenols").
Application: Health tea from olive leaf extract may help lower blood sugar (consult a doctor).
3. Cosmetics and skin care products
Antioxidant skin care
Hydroxytyrosol and olive polyphenols combat UV-induced skin aging by reducing wrinkles/pigmentation.
Products: Anti-aging creams, essences, sunscreens often labeled "Olive."
