Can olive extracts cure diabetes
Olive leaf extract - effect and application
It is no secret that olive oil has a particularly high health value among all edible oils. However, highly concentrated olive leaf extract is even more effective than pure olive oil. As the name suggests, it is obtained from the leaves of the olive tree and, in contrast to the olive fruits and their oil extracts, which are mainly used as food, is a naturopathic remedy. It is used, among other things, for digestive complaints, liver diseases and skin problems. But why is olive leaf extract so much more effective than other extracts from the olive tree? Our contribution to the topic provides information.
Olive leaf extract - areas of application
Taken as tea or vital capsules, the extract of olive leaves is effective against a variety of diseases, including:
- Skin and hair problems,
- Liver disease,
- Cardiovascular diseases
- and metabolic disorders.
Of course, the oil extract of olive fruits also has similar effects. However, the healing effect here is rather preventative on nutrition, whereas the extract of the olive leaves acts as a real medicinal substance.
The olive leaf
The evergreen leaves of the olive tree are up to ten centimeters long and have a distinctive, elliptical shape, which is divided in the middle of the leaf on both sides by a striking central rib. While the upper side of the leaf has the classic dark to gray-green color of the olive leaves, the underside is colored silvery gray and has small leaf hairs.
Olive leaves stand out due to their comparatively leathery and hard surface. This is indispensable for the leaves in order to be able to survive in the hot, dry and sunny climate of the olive tree's regions of origin. Leaves that are too thin and soft would burn up here in no time at all. In addition, the nature of the olive leaves is also determined by their ingredients. These consist largely of essential oils with a low water content, which also contributes to the viscous consistency of the leaves.
As is well known, the olive tree has been cultivated as a useful plant for a very long time. The oldest finds, which prove the cultural use of the tree, go back to the fourth millennium BC. However, this mainly concerned the use of olives and olive oil.
The medicinal properties of olive leaves, on the other hand, only attracted greater attention relatively late. It is known today that the ancient Egyptians relied on the disinfecting effect of pressed olive leaves for the mummification of corpses, but this only became medically significant in the Middle Ages.
One of the first to describe it was the famous herbalist Hildegard von Bingen. She recommended olive leaf tea in the 12th century for ailments and diseases of the digestive tract as well as high blood pressure and thus also helped the olive leaf extract to gain more international reputation.
Nowadays, olive leaf tea is a popular remedy, especially in the Mediterranean region. But the benefits of olive leaf extract are also being rediscovered more and more in Germany and the rest of Europe. It is now even sold in capsule form and is supposed to ensure that the extract is easier to take without the bitter taste typical of olive leaf tea.
Olive leaf extract - medicinal properties
By and large, olive leaves have the same ingredients as all other parts of the olive tree. However, some plant substances are particularly highly concentrated in the leaves of the useful wood, which also explains why olive leaf extract is so much stronger than olive oil. Above all, it is the plant substance oleuropein, which is found in the olive leaf in about 3000 times higher concentration than in olive oil and thus has a much greater healing effect.
Oleuropein is one of the so-called terpenes and especially one of the bitter substances. These are known for their digestive effects, which is why olive leaf extract specifically helps with digestive problems such as constipation or flatulence. In addition, oleuropein also has an intense one
- and immune boosters
Effect so that even infections localized in the gastrointestinal tract can also be treated, such as those that occur in gastritis or forms of colitis. Other inflammatory infectious diseases, such as respiratory, urinary tract and skin infections, can also benefit from the active ingredients in the olive leaf extract in this context.
The extract can even show positive effects on inflammatory diseases of the musculoskeletal system such as rheumatism or arthritis.
Another beneficial property of oleuropein is its antioxidant effect. It plays an important role with regard to heart and vascular diseases, as these are often caused by the oxidation processes of pollutants or the deposition of vascular plaque.
The administration of olive leaf tea to patients with high blood pressure or arteriosclerosis by Hildegard von Bingen had a method. And even metabolic diseases such as diabetes or high cholesterol indicate the use of oleuropein-containing olive leaves
- blood sugar lowering,
- lowering cholesterol,
- as well as strengthening the heart and circulation
Act. A number of other active ingredients can be found in olive leaves that share or strengthen the healing properties of oleuropein. Especially other terpenes from the class of iridoids such as
- Elenolic acid,
- Maslinic acid
- and oleanolic acid,
But also various flavonoids, which give the olive leaf extract its typical golden yellow color, are worth mentioning in this regard. The aroma that arises in the olive leaf extract as well as in the olive leaf tea is bitter-sweet, depending on the ingredients, with a green-natural note.
By the way: Scientists at the University of Leipzig were able to show through a study that the active ingredients contained in olive leaf extract are able to inhibit the enzyme xanthine oxidase. This is responsible for the development of gout, which is why even gout patients may benefit from using the extract.
Olive leaves as medicinal herbs
The traditional use of olive leaf extract is in the form of tea. It is recommended to use fresh leaves or leaves previously dried on the branch.
To prepare a cup, take about a tablespoon (tablespoon) of the olive leaves, pour 250 milliliters of boiling water over them and then let the tea steep for about 20 minutes. The long steeping time is important because this is the only way to remove the medicinally effective ingredients from the hard leaf herbs. After the tea has drawn through, the leaves are sieved and the tea is drunk in small sips. Up to three cups of the olive leaf tea can be consumed daily.
Tip: Olive leaf tea is a good alternative for people who cannot tolerate olive oil for reasons of intolerance. This is the case with some pollen allergy sufferers, for example.
There are a number of other extraction methods as well as various interesting recipes. For example, you can soak the leaves in high-proof alcohol and get an olive leaf tincture. For this purpose, you fill a large screw-top jar to the brim with olive leaves and then pour vodka or brandy over it.
Well closed, the container then has to mature in the sunlight on the windowsill for two to four weeks. Then the olive leaves are filtered off and the tincture can be stored in a dark bottle protected from light. Diluted with water, such a tincture is used, among other things, to make capsules from olive leaf extract. We have listed a few more interesting recipes for you below.
Bitters with olive leaves
In order to stimulate digestion or to alleviate undesirable accompanying symptoms in existing gastrointestinal diseases, a digestive schnapps can be helpful after a meal. In addition to numerous recipes for bitters made from herbs such as aniseed or fennel, the healing powers of olive leaf extract can also be used for this purpose.
- 700 milliliters of vodka
- 100 grams of cane sugar
- 50 grams of olive leaf tea
- Half a lemon
- Put the olive leaves together with the vodka, the cane sugar and the zest of half a lemon in a previously cleaned mason jar.
- The liquor must then be stored in a cool and dark place for four weeks. Shake the container well every day to allow the sugar to dissolve completely.
- As soon as the four weeks of ripening time have passed, filter out the coarse components and store the bitters in the refrigerator until use.
As an alternative to vodka, you can also use other types of alcohol such as brandy, rum or alcohol, depending on which taste suits you better.
Day cream made from olive leaf extract
Creams and ointments made from olive leaf extract are of course particularly suitable for skin care, as well as for the treatment of skin diseases. Since creams contain other skin-active additives in addition to olive leaf extracts, they can even be used for daily care.
- 35 grams (g) of well-boiled olive leaf tea
- 7 g jojoba oil
- 3 g shea butter
- 2.5 g Lanette O
- 2 g urea
- 0.5 g Rokonsal BSB-N
- a drop of lactic acid
- The production of creams always requires the separate preparation of fatty ingredients (Fat phase) and water-based ingredients (Water phase). For the fat phase, therefore, first heat the fatty shea butter at around 40 degrees Celsius in a water bath and wait until it has completely melted.
- Next, the jojoba oil and Lanette O are mixed in with constant stirring with a whisk. The latter is an emulsifier that ensures that the fat phase mixes well with the water phase later.
- A separate water bath is prepared for the water phase in which you mix the olive leaf tea, urea, lactic acid and the preservative Rokonsal BSB-N one after the other. Urea is known to be an extremely valuable ingredient for skin care, while lactic acid serves as a humectant and pH regulator.
- After preparing the two phases, remove them from the hotplate and let them cool down for a few minutes. At the end of the day, both the fat and water phases must have a temperature of 40 degrees Celsius before they are mixed together. This is done by mixing in the water phase drop by drop with the fat phase. It is best to use a hand blender to make your work easier.
- As soon as the cream has been mixed, it is poured into a clean, dark cream jar. Seal the jar airtight and it is best to store it in the refrigerator as long as you don't need the cream. The cool and light-protected environment extends the shelf life of the olive leaf day cream immensely.

Side effects of olive leaf extract
As with olive oil, hypersensitivity reactions can occasionally occur with olive leaf extract if the user is allergic to pollen. Conceivable side effects then mainly consist of diarrhea and allergic skin reactions. We therefore advise allergy sufferers to test only small amounts of the extract in advance to ensure that there is no intolerance. (ma)
