on

Olive leaf extract refers to a supplement that is derived from the leaves of the olive tree (Olea europaea). Numerous scientific studies have revealed various health benefits that are associated with the use of olive leaf extract.

According to the studies, the uses of olive leaf extract range from promoting a healthy blood pressure to boosting the immune system and the general health of the cardiovascular system.

What Is Olive Leaf Extract?

The current health professionals first used olive leaf extract in the year 1995. The initial results of its use were very positive. Olive leaf extract is emerging as a promising herbal product that has numerous applications. Studies have shown its potency against common conditions.

The primary chemical ingredients that are present in olive leaf extract include hydroxytyrosol and oleuropein. Other components of the leaf extract include oleanolic acid, oleacein, and oleanolic acid. Studies have shown that hydroxytyrosol is readily absorbed in the intestines. It is metabolized and quickly excreted in urine in the form of glucuronide conjugates.

The bioactive substances that are found in olive leaf extract have antihypertensive, antioxidant, and anti-inflammatory properties. The bioactive substances are also hypocholesterolemic and hypoglycemic.

Uses for Olive Leaf Extract

1. Reducing the Risk of Cancer

Several studies have revealed the ability of olive leaf extract to reduce the risks that are associated with cancer. Oleuropein bioactive has been shown to play a fundamental role in the extract's anticancer effects.

The antioxidant property of oleuropein has been demonstrated to prevent the development of the cancer cells at their early stages. The initial stages of cancer development involve the destruction of the DNA by the reactive oxygen species. The antioxidant property of oleuropein prevents this from taking place.

The extract has been shown to inhibit signaling pathways and growth factors that are essential for the growth and stabilization of cancer cells in the human body. The oleuropein bioactive has also been shown to inhibit an enzyme that is responsible for the provision of energy derived from dietary carbohydrates.

Other mechanisms of action against cancer include prevention of inflammation, which is another requirement for tumor growth. Oleuropein also prevents the response by malignant cells to estrogen in breast cancer. The bioactive compound also inhibits the production of enzymes that are required by cancerous cells to metastasize and invade healthy cells.

2. Neuroprotection

Olive leaf extracts have the ability to protect the central nervous system from the destruction that may be caused by conditions such as stroke and Alzheimer's. The anti-inflammatory effect of olive leaf extract minimizes the damages that may be caused to the brain.

They also reduce the damages that may arise from oxidative stress. Olive leaf extract also offers protection against oxidative stress that may result from a neurodegenerative disease. The extract works by preventing abnormal proteins from accumulating in the neurofibrillary tangles as seen in individuals with Alzheimer's.

3. Arthritis

Since ancient times, olive leaf extracts have been used in the management of arthritis. Recent studies have revealed that the herbal product can be used in preventing the development of various types of arthritis such as gout and osteoarthritis.

Gout is a musculoskeletal disease that results from the accumulation of uric acid crystals in the body. Uric acid is a product of the metabolism of DNA and RNA by xanthine oxidase enzyme. Oleuropein has been shown to prevent the breakdown of the nucleic acids by inhibiting xanthine oxidase.

The bioactive substance has also been shown to improve symptoms that present with rheumatoid arthritis. It produces similar benefits in individuals diagnosed with osteoarthritis.

4. Diabetes

Chronic elevation of blood sugar levels is associated with an oxidative stress all over the body that leads to rapid tissue damage and inflammation. Management of diabetic patients is aimed at lowering the blood sugar levels and minimizing complications that result from the inevitable blood sugar spikes.

Lab studies that were conducted in animals have shown that olive leaf extract has a real promise in the management of diabetic patients. The mechanism of action of the extract includes slowing the breakdown of starches to simple sugars. Olive leaf extract is also capable of slowing the absorption of simple sugars from the intestine and enhance its uptake into tissues. The extracts also prevent tissues from oxidant damage that may arise when glucose binds to proteins.

Olive leaf extract is also capable of increasing the amount of other natural antioxidants in the body. A study that was performed in humans showed that a daily consumption of 500mg of olive leaf extract could help reduce the levels of hemoglobin A1C levels. Elevated levels of the hemoglobin A1C levels is a standard marker of long-term exposure to raised levels of blood sugar.

5. Blood pressure

Studies have shown that a daily intake of 500mg of olive leaf extract can be beneficial to patients with high blood pressure. The product has been demonstrated to reduce both systolic and diastolic pressures.

Risks And Side Effects

According to WebMD, olive leaf extract is safe when it is administered by the oral route. It is also safe to apply it on the skin. However, there are some reports of delayed allergic responses and contact dermatitis when olive leaf extract is used on the skin.

There is inadequate evidence to support the safety of olive leaf extract. Pregnant and breastfeeding mothers are cautioned against using high amounts of olive leaf extract.
