The main active components of olive leaf extract are oleuropein and hydroxytyrosol,with good photoprotective and antioxidant effects. Oleuropein is an important benzoic acid schizocycloalkene alkaloid compound with strong antioxidant capacity. Studies have shown that it can slow down the oxidation of low-density lipoprotein, prevent coronary heart disease, atherosclerosis, as well as soothe smooth muscle and lower blood pressure.
How to Use Olive Leaf Extract?
Olive leaf extract can be used externally or internally.
1. Add 5-10 drops of olive leaf extract to your facial cleanser or lotion to get the most out of olive leaf's skin benefits.
2. Take olive leaf extract directly into capsules or orally to support immune function, promote cardiovascular health, and boost antioxidant capacity. It can also be taken with a meal or with a snack.
3. You can also make tea directly from olive leaves. In general, olive leaf extract is generally safe when used in moderation. In some cases, olive leaf extract may cause dizziness in people with low blood pressure. Because it can further lower blood pressure, do not take olive leaf with blood pressure or blood sugar lowering medications.
Active Ingredients
Oleuropein is distributed throughout the olive tree, but the content is different in different parts, with the highest content in the leaves. The study found that there are several groups of active molecules in olive leaves:
• Isolation of iridoid derivatives (oleuropein and verbascoside)
• Flavonoids (luteolin, apigenin, luteolin and pelargonin)
• Flavonol (rutin)
• Flavans (catechols)
• Substituted phenols (tyrosol, vanillin, vanillic acid, caffeic acid)
• Glycoside (luteolin)
• Enzymes (lipase, peroxidase)
• Other molecules such as oleocanthal, N-pentane, oleanolic acid, malic acid, lactic acid, tartaric acid, coliforms, tannins, glucose, sucrose, mannitol and essential oils.
Hydroxytyrosol in natural olives has excellent antioxidant activity, and the ability to absorb oxidative free radicals is 30 times that of vitamin C. As a new generation of anti-aging ingredients, hydroxytyrosol is also a popular anti-aging whitening ingredient. It is a natural polyphenolic compound with various biological and pharmacological activities. It is not only used in the synthesis of cardiovascular drugs, but also as a safe and efficient antioxidant.
