Olive leaf has been known as one of the most effective herbal medicines in traditional medicine since ancient times. This small but characteristic leaf is full of active and useful compounds that directly affect the health of the body. One of the main compounds found in olive leaves is oleuropein, which is known as a strong antioxidant. In addition to its antibacterial and antiviral properties, olive leaves help strengthen the immune system and reduce inflammation. The use of olive leaves in various forms such as tea, extract and even as a supplement is popular in many countries and scientific research has confirmed these benefits. In the following, we will learn more about the amazing properties of this plant.
Olive leaf properties
Strengthening the immune system and fighting diseases
Olive leaf is one of the most powerful natural boosters of the immune system. Antioxidants in this leaf, including oleuropein, directly fight free radicals in the body and protect cells from oxidative damage. This property makes the body more resistant to pathogens such as viruses, bacteria and fungi. In addition, the compounds in olive leaves can increase the production of immune cells and improve the overall function of the immune system. Consuming tea or olive leaf extract regularly, especially in the cold seasons of the year, can reduce the possibility of contracting infectious diseases.
Lowering blood pressure and improving cardiovascular health
Olive leaf has significant effects in lowering blood pressure. The active compounds of this plant can prevent vasoconstriction and help dilate the vessels, which leads to a decrease in blood pressure. Research has shown that oleuropein present in olive leaves, in addition to reducing blood pressure, also reduces the level of bad cholesterol (LDL) and prevents the accumulation of plaques in the walls of arteries. These features help prevent cardiovascular diseases and reduce the risk of heart attacks and strokes. Therefore, consuming olive leaves can be part of a healthy diet to maintain heart health.
Blood sugar regulation and diabetes control
Controlling blood sugar levels is one of the biggest challenges in the lives of people with diabetes. Having anti-diabetic properties, olive leaf can help regulate blood sugar. The compounds in this leaf increase insulin sensitivity and improve glucose absorption by cells. Research has shown that regular consumption of olive leaf extract can reduce fasting blood sugar levels and even hemoglobin A1c in diabetic patients. Also, this plant helps to prevent complications caused by diabetes such as damage to blood vessels and nerves.
Anti-inflammatory properties and chronic pain relief
One of the most important properties of olive leaf is its anti-inflammatory properties. Chronic inflammation in the body can be the cause of many diseases such as arthritis, heart disease and even cancer. The anti-inflammatory compounds found in olive leaves help reduce inflammation by reducing the production of inflammatory molecules in the body. Regular consumption of this leaf can help relieve chronic pain caused by inflammation, such as arthritis or muscle pain, and improve people’s quality of life.
Skin and hair protection
Olive leaf has amazing effects on skin and hair health due to its strong antioxidants. By neutralizing free radicals, this plant prevents premature skin aging and helps reduce wrinkles. Also, the antibacterial properties of olive leaves can help treat acne and other skin problems. Using tea or extract of this plant, in addition to improving skin health, also helps strengthen hair follicles and prevents hair loss.
Detoxification and improvement of liver function
The liver is one of the most important organs in the body for eliminating toxins, and olive leaves can improve the function of this vital organ. The compounds in the olive leaf help cleanse the liver of toxins and harmful substances and strengthen its function. Regular consumption of olive leaves can help prevent liver diseases such as fatty liver and promote overall health.
Cancer prevention
Antioxidants in olive leaves play an important role in preventing cancer. By fighting free radicals, these compounds prevent DNA damage and genetic mutations that can lead to cancer. Studies have shown that consuming olive leaves can help reduce the risk of various cancers, including breast, prostate, and colon cancer.
Increase energy and reduce fatigue
Olive leaf not only helps to improve the overall health of the body, but can also increase energy levels. This plant reduces fatigue and increases body energy by improving blood circulation and providing oxygen and nutrients to cells. Olive leaf tea is a great choice to start an energetic day.
Help to lose weight and control appetite
If you are looking for a natural way to lose weight, olive leaves can be a good option. This plant helps to burn fats by strengthening the body’s metabolism. In addition, the blood sugar regulating properties of olive leaves can prevent a sudden increase in sugar and false appetite and help control weight.
Harms of olive leaves
Excessive lowering of blood pressure
Olive leaf is beneficial for people suffering from high blood pressure due to its blood pressure lowering properties, but its consumption can be dangerous for those with low blood pressure. This herb may lower blood pressure to the point of causing dizziness, weakness, or even dangerous hypotension. In such cases, people may feel tired or lethargic all the time. If you have naturally low blood pressure or are taking blood pressure medication, you should avoid olive leaf or consult your doctor.
Interference with diabetes medications
Due to its ability to reduce blood sugar, olive leaf can be useful for people with diabetes. But this property can be problematic in people who use blood sugar control drugs. Concomitant use of olive leaves with these drugs may cause a severe drop in blood sugar (hypoglycemia), which causes symptoms such as tremors, weakness, excessive sweating, and even loss of consciousness. Therefore, diabetic patients should use olive leaves carefully and under the supervision of a doctor.
Allergic reactions and sensitivities
Some people may be allergic to olive leaves. These sensitivities can appear in the form of skin reactions such as itching, redness and inflammation or even more severe symptoms such as shortness of breath and swelling. People with a history of allergy to olives or related products should use caution before consuming olive leaves. If you experience allergic symptoms after consuming this plant, it is better to stop using it immediately and see a doctor.
Digestive disorders
Consuming too much olive leaf or its extract can cause digestive problems. Some people may experience symptoms such as stomach pain, diarrhea, or nausea. These problems are usually caused by the effects of the compounds in the olive leaf on the walls of the stomach and intestines. To avoid these complications, it is better to limit the consumption of olive leaves to the recommended amount and avoid overdoing it.
Decreased calcium levels and risk of osteoporosis
Some studies have shown that long-term and excessive consumption of olive leaves may cause a decrease in calcium levels in the body. This can lead to weakened bones and an increased risk of osteoporosis. Although this effect is rarely reported, people who are at risk of osteoporosis should use olive leaf with caution and consult their doctor.
Possible risks for pregnant and lactating women
Pregnant and lactating women should avoid consuming olive leaf or use it with great caution. Although there is no conclusive evidence on the negative effects of olive leaf during pregnancy, the active compounds of this plant may stimulate uterine contractions and increase the risk of premature birth. Also, the effect of olive leaf on mother’s and baby’s milk has not been fully investigated and it is better to avoid its use during this period.
Possible effects on thyroid function
Olive leaf may affect thyroid function. Some studies have shown that high consumption of this plant can disrupt the production of thyroid hormones and lead to problems such as hypothyroidism. People who have thyroid diseases or take medicines related to these diseases, should be careful in using olive leaves and consult their doctor before using them.
Risk of interaction with anticoagulants
Olive leaf has anti-inflammatory and blood-thinning properties, but this property can cause problems for people who take blood-clotting drugs such as warfarin or aspirin. Concomitant use of olive leaf with these drugs may increase the risk of bleeding. If you are taking blood thinners, it is best to avoid olive leaf or do so under the supervision of your doctor.
