Olive leaf can improve nerve growth in certain parts of the brain and protect the nerves from oxidative damage. Although trials on humans have not been conducted yet, an animal study indicates that oleuropein in olive leaves lowers and even avert the buildup of beta-amyloid protein plaques in the brain – which can result in the death of nerve cells and the onset of Alzheimer’s disease.

Olive leaves appear to be also effective in fighting Parkinson’s disease. The antioxidants contained in the herb, mainly oleuropein, can combat oxidative damage and inhibit the death of nerve cells that produce dopamine, a symptom of Parkinson’s.

Precautions and Side Effects

Some of the potential side effects of olive leaf include:

Stomach Problems: Due to how powerful olive leaves are, an excessive consumption of the extract can lead to stomach irritations or in some cases, excessive diarrhea. The herb is, therefore, recommended to be taken with food. As a tea made from olive leaf and with drinking extra water, excess toxins can be flushed out of the body. For people who experience these gastrointestinal side effects, they should stop using the supplement and consult with a doctor.

Heartburn: There are reported cases of some people experiencing heartburn when they drink olive leaf tea, but this isn’t often the case for people who take olive leaves in the form of supplements in tablets or capsules.

Inflammation: The herb contains powerful anti-fungal, antibacterial, and antiviral properties. However, when the pathogens responsible for diseases get killed, they release toxins into the body. This makes the body’s immune system to kick back by detoxifying itself of toxic material which causes inflammatory reactions such as muscle soreness, headache, joint pain, sweating, and fever.

Lightheadedness: Few people have reported side effects like dizziness after using olive capsule supplements. This seems to be common in people who already have low blood pressure, especially as olive leaf has a hypotensive effect on the body.

Drug Interactions: Ironically, olive leaves can also elevate blood sugar levels and lower blood pressure. For those undergoing conventional treatments for hypertension or diabetes, the interactions with the herb could lead to certain health complications.
