Traditionelle Medizin mit Pflanzen und Buch auf dem Tisch

When Prof. Pahnke published his findings regarding the use of Greek mountain tea (Sideritis scardica) in Alzheimer’s disease a few years ago, this caused a boom in the centuries-old home remedies. His commitment brought him the title “Alzheimer’s hunter”. Prof. Pahnke has done us a great favor by participating in a video series, in which the development of Alzheimer’s and his relevant research are clearly explained.

The passion with which he pursues the topic is not just a matter of chance. On his website, based on his research results, there is a lot of positive feedback from patients who take a combination preparation of Greek mountain tea and St. John’s wort. You can read all reports here.

The beginning

At the beginning of his studies, Prof. Pahnke examined many plant extracts for their suitability for treatment of Alzheimer’s. The problem that the scientists were facing was to find a substance that activates the transport molecules in the brain – a main problem in the treatment of the disease. Plant extracts have been used for many years to treat mental illnesses or diseases of the brain. Prof. Pahnke started his studies with these plants over ten years ago.

The focus was initially on Humulus lupulus (hops), Camellia sinsensis (green tea), Hypericum perforatum (St. John’s wort) and Ginkgo biloba, all of which are used in the field of neurological diseases. After a brief review of the available studies, Ginkgo biloba was quickly eliminated because its effect on Alzheimer’s had already been examined. Unfortunately without positive results (you can find more information here).

Hops and green tea were also soon eliminated. St. John’s wort is already used to treat neurological diseases, especially mild to moderate depression. When the researchers examined the effect of St. John’s wort on Alzheimer’s symptoms in a mouse experiment, a promising effect was clearly recognizable.

Best results by combining St. John’s wort and Greek mountain tea

Prof. Pahnke and his team have found that St. John’s wort extract, (80% ethanolic extract), activates the “waste disposal” in the brain to remove the amyloid. In patients with Alzheimer’s disease, its consumption led to an improvement of the dementia symptoms, the ability to speak and the day-night rhythm.

Encouraged by the results with St. John’s wort, the scientists looked around for other suitable plants. After a long search, Prof. Pahnke’s team came across Greek verbena or Greek mountain tea, (Sideritis scardica). In the Balkans, the plant is well known as a tea infusion. It is mostly drunk in case of colds or stomach problems. The Greeks affectionately call it “health tea”. A wide variety of remedies for colds or for strengthening the immune system based on Greek mountain tea has been on the market since 1960.

After several tests, the scientists were able to demonstrate a biological effect of Sideritis scardica (Greek mountain tea) extract in Alzheimer’s dementia. The number of plaques in the brain was reduced by 80%, the number of nerve cells was normalized and the ability to learn was improved. A detailed explanation can be found in our video series

There are many sub-species of Greek mountain tea, but only the sideritis scardica variety showed this effect. (If you are more interested in how Prof. Pahnke approached the use of Greek mountain tea, we recommend our blog article “Greek mountain tea: Consumption as tea or extract?” In this article, Prof. Pahnke answers some frequently asked questions on this topic.) 

The combination of Greek mountain tea (40 % ethanolic extract) and St. John’s wort (80% ethanolic extract) appears to be particularly useful as both plant extracts have shown an effect on Alzheimer’s symptoms. Greek mountain tea dissolves the plaques in the brain, while St. John’s wort removes them. This interaction is crucial.

The positive side effect of St. John’s wort is also the mitigation of the depressive symptoms that are often associated with Alzheimer’s dementia.

Of course, it must be said that extracts from Greek mountain tea or St. John’s wort cannot cure Alzheimer’s. However, many relatives of Alzheimer’s patients report that their condition has improved significantly after taking the combination preparation (Renovare 500). Read the detailed reports here.

Greek mountain tea and St. John’s wort are also herbal products. Greek mountain tea, (Sideritis scardica), does not have any known side effects or interactions. St. John’s wort can temporarily activate the liver degradation enzymes. Therefore, if you are taking other important drugs, you should adjust your body to a lower dose. You will soon find out more about St. John’s wort on our blog. If you would like to know more about this in advance, you will find an explanation by Prof. Pahnke in our video series.
