What is Olive Leaf Tea

What is Olive Leaf Tea? 

Olive Leaf Tea uses leaves from the olive tree (Olea europaea). This tree, in turn, belongs to the Oleaceae family. Fossil evidence indicates that it has grown in the eastern Mediterranean basin for some 40 million years. It has since spread and naturalised throughout much of Africa and Asia.

During the course of millennia, the appearance of Olea europaea has changed very little. Most recognise it as being relatively short in size. Indeed, it rarely exceeds heights of 26-49 feet. It grows both fruits and flowers, the latter being small, white and feathery. Its much-loved edibles, meanwhile, need little introduction.

The leaves of the tree, in comparison, have only recently received the recognition they sorely deserve. Before brewing as a Loose Leaf Tea, they are silvery-green in colour. These olive leaves can grow to be 4-10 cm long and 1-3 centimetres wide. Once they reach your morning cuppa, they offer a soft, mellow, herbaceous flavour.

During the 19th Century, subtropical British colonies crushed and brewed them for fever relief. Today, this is just one answer to the question, “What is Olive Leaf Tea Good For?”. As of 2019, we know much, much more about this remarkable beverage

Does Olive Leaf Tea Have Caffeine?

Does Olive Leaf Tea Have Caffeine?

The likes of Green, Black, White and Oolong Tea all come from one plant: Camellia sinensis. This is one of around 60 plants that naturally contain caffeine, with others including Coffea (Coffee) and Theobroma cacao (chocolate). (Read our article, “Caffeine in Tea and Coffee” or “Effects of Caffeine”, for more caffeine-related information).

So, what about this particular brew? Does Olive Leaf Tea Have Caffeine? No. Almost all Herbal Teas, excluding Yerba Mate, are entirely caffeine-free. This is good news for those who’re either caffeine sensitive or those who’re, put simply, looking to cut down. Furthermore, it makes Olive Leaf Tea an excellent choice of beverage before bed.

What is Olive Leaf Tea Good For?

What is Olive Leaf Tea Good For?

What is Olive Leaf Tea Good for, you might ask? The answer is “plenty”! But why? And how? For starters, it boasts antioxidant, antihypertensive, anti-atherogenic, anti-inflammatory and hypocholesterolemic qualities.

Let’s go through this in order. The antioxidants in this Tea, particularly a chemical compound called oleuropein, have a significant influence on your health.

This is because they can combat free radicals in the body, the product of natural, though harmful, human oxidation. In doing this, Olive Leaf Tea’s antioxidants help in reducing the risk of developing several chronic conditions.

Its antihypertensive properties, meanwhile, are the primary reason that Olive Leaf Herbal Tea works in lowering blood pressure. Then there are its anti-atherogenic properties, which prevent or inhibit atherogenesis antiatherogenic effects. This, in other words, refers to it blocking the formation of fatty deposits in the arteries.

Next, its anti-inflammatory properties (as the name suggests) reduce inflammation. This has a significant role to play in improved skin health. Finally, we have its hypocholesterolemic effects - a much-needed support in the fight against “bad” LDL cholesterol.

Already in Germany, Hungary, Japan and the United States, Olive Leaf Tea is prescribable as an alternative Herbal remedy. Is it only a matter of time before the UK adopts this view, too? Below you will find more information on the specifics of “what is Olive Leaf Tea good for?”. 

Olive Leaf Tea Blood Pressure

1. Helps to Blood Pressure

There is a significant amount of evidence supporting Olive Tea’s ability to safely lower blood pressure. One particularly interesting study, conducted by researchers from Switzerland and Germany, used the concept of a “twins” trial. By using identical twins, this increased the power of the resulting data by eliminating some uncertainties caused by genetic variations.

The study saw 20 identical twin pairs, all of whom had high blood pressure, split into two groups. The first group received a placebo while the second group consumed capsules containing Olive Leaf extract. After eight weeks, the researchers concluded that Olive extract  lowered blood pressure due to its remarkable antihypertensive properties.

Furthermore, it’s worth noting that this infusion can support heart health in other ways, too. As mentioned previously, Olive Leaf Tea contains high levels of antioxidants, which fight numerous chronic conditions. One such condition is, in fact, cardiovascular disease. So, in other words, it can keep your ticker in check on several fronts. Pretty neat for your new favourite brew, wouldn’t you agree? 

Can Aid Weight Loss

2. Can Aid Weight Loss

This beverage might promote weight loss in a couple of ways. First, it is exceptionally low in calories, which in itself contributes to improved weight management. What’s more, there is a possibility that it might boost the metabolism of fat cells in the body. A study conducted at the University of Southern Queensland and published in the American Journal of Nutrition can explain how.

Australian researchers started by feeding rats a high-carbohydrate, high-fat diet for eight weeks until they developed signs of metabolic syndrome. This brought about increased abdominal fat, fatty liver, hypertension and impaired glucose tolerance. The rats then received Coffee fortified with olive leaf extract for another eight weeks, resulting in improved metabolic signs.

Whether or not these results apply to humans, too, remains to be seen. However, it looks relatively promising. Ultimately, drinking this Tea might help, if only slightly, to get you back into your favourite pair of jeans. What more could you want from your morning cuppa?

Benefits Your Skin

3. Benefits Your Skin Health

Olive Leaf Tea can protect against a multitude of skin conditions. One study, for example, found that the antioxidant oleuropein accelerates wound healing. Another study, on the other hand, discovered that it offered outstanding anti-ageing properties, and could even protect against sun damage. However, this is merely scratching the surface.

There are suggestions that this beverage can, among other qualities, eliminate harmful bacteria from developing into skin-related infections. It might also be beneficial when treating dermatitis.

If that wasn’t enough, it is known to reduce redness, to hydrate and to stimulate the growth of new skin. Ultimately, Olive Leaf tea can give you healthy skin. It’s the gift that keeps on giving when it comes to maintaining a fresh, healthy and  youthful outer appearance.

Keeps you Hair Looking Healthy

4. Keeps Your Hair Looking Healthy

Is your choice shampoo no longer doing the trick? Consider using Olive Leaf Tea benefits when maintaining your luscious locks! Although not yet proven, there is early evidence to suggest that this beverage may contribute to moisture and shine.

Furthermore, it might have the ability to smooth out loose strands while even, potentially, promoting hair growth!

This is according to an animal-based study conducted by Yonsei University, South Korea, which noted that olive extract could stimulate anagen hair growth in mice.

It’s vital to recognise, however, that there may also be some side effects associated with this particular benefit. As such, we recommend consulting a doctor or another health professional before experimenting.

Can Reduce Diabetes Risks? 

5. Can Reduce Diabetes Risks? 

Before we get into this, it’s essential that you note that all research into Olive Leaf Tea and diabetes is in its preliminary stages. As such, The Kent and Sussex Tea and Coffee Company do not endorse its consumption for this purpose. Nevertheless, we’re here to tell you the facts, and there are, indeed, potential correlations between this infusion and reduced diabetes risks.

One New Zealand study conducted by The Liggins Institute at the University of Auckland can explain how this might work. It showed that fresh olive leaf extract could help support blood sugar and insulin levels - crucial to glucose regulation.

Evidence from another study published in the Journal of Medicinal Food might also support such a claim.

Ultimately, Olive Leaf Tea’s (potential) ability to balance blood sugar levels and insulin could lead to the prevention of type-2 diabetes. However, and we can’t stress this enough, it’s vital that more studies are conducted before making any conclusions.

Olive LeaKnown Side Effects Tea Side Effects

Known Side Effects

There is little evidence to suggest that drinking Olive Leaf Tea has any adverse side effects. Some have speculated, however, that it might trigger mild stomach pain and headaches.

A few people might also find themselves allergic to plants in the Oleaceae family. This includes ash trees, lilacs, jasmine, forsythia, privets and, of course, olive trees.

Furthermore, there is a risk that it might interact with certain medicines. Do not drink Olive Leaf Tea, for example, if you’re taking blood pressure medications. If you have any concerns, be sure to talk to your doctor or another health professional. They will, of course, know best.
