Recipe for the Treatment of Cardiovascular Diseases

Prescription for the treatment of cardiovascular diseases

Honey and horseradish therapeutic treatment is based on an ancient tradition of folk medicine and can be used by patients suffering from angina pectoris with painful cardiac perfusion (ischaemia).
For the preparation peel and grate the horseradish, so much that you can fill a tablespoon with it. Then mix the grated horseradish with a tablespoon of acacia honey until a homogeneous mass is obtained. The mass must be stored dark and cool. The preparation is slowly consumed with a teaspoon one hour before breakfast each morning until the prepared amount is used up.
Since honey dampens the pungent taste of horseradish and horseradish in turn softens the overly sweet taste of honey, the blend has a pleasant taste.
There is increasing evidence that foods rich in flavonoids and beekeeping products such as propolis, bee pollen and bee bread, after some time of ingestion, reduce the risk of cardiovascular disease by eliminating free radicals present in the body Associated with atherosclerosis occur more frequently. The menu includes foods rich in flavonoids such as broccoli, carrots, black currants, grapefruit, white lemons, pomegranates, dark chocolate, soybeans, oranges, apples, tomatoes and onions, as well as the aforementioned bee products.

Mixed Forests and their Benefit

Mixed Forests and their Benefit

How Importsant is the Forest

The forest is more than just a habitat for plants and animals, a supplier of wood or the piece of nature in which we take our Sunday walk. An intact forest fulfills many other functions – which makes it all the more important for it to be sustainably managed and protected.

mixed forests and their benefit

mixed forest in autumn

The forest is not in vain considered the “green lung” of our planet: it purifies the air, stores carbon dioxide and supplies fresh oxygen. Even a single tree, for example a 25-meter-high beech, produces enough oxygen during the summer to create breathing air for ten people. At the same time, thanks to the enormous leaf area of ​​1,600 square meters, such a tree looks like a dust filter – it takes us a ton to get it out of our air in one year.

In addition, for the development of the child a varied stay in nature is of great importance. Take advantage of all the opportunities that the forest offers to escape the stress and hectic pace of everyday life with your child. Not a few children, so-called “Zappelphilippe”, get tablets prescribed to come to rest. But is this always appropriate? Bringing calm and balance into the life of your offspring is a goal that parents can achieve with simple means and, on top of that, a lot of fun.

Another important aspect when considering the weather development is that a healthy mixed forest, due to the water-retaining ability of the forest soil preserves the landscape from soil erosion (= erosion) by rapidly draining surface water. The forest can also prevent the risk of ground slippage, as the widely branched root network of the trees provides support for the soil.

You see, the mixed forest has many tasks to fulfill. Conserving mixed forest is therefore an important requirement. setzt auf ökologische Wirtschaftsweise

Environmental Awareness in Daily Life

Environmental Awareness in Daily Life

Renew environmental awareness daily

The fact that I have to sharpen my environmental awareness every day makes me think. Why is it so difficult to reorganize regular processes in my view of the environment? Man is just a habit animal.

But at least I realize that I’m making mistakes. It starts with brushing my teeth in the morning. I turn on the water to moisten the toothbrush and let it run until I’m done. What a waste! As much as 7 liters of water just flow into the drain. But since I know that by 2050 more people from Wassernot will be leaving their country than today for fear of war and persecution, I have put an end to this bad habit. This message has sensitized my environmental awareness.

environmental awareness towards the water

At Planet Wissen you can read that in Germany per day / person 123 l of drinking water are consumed. Thanks to our efficient water cycle, compared to other EU countries, this is comparatively little but still a huge amount, considering how much of it is wasted. Take care. Whether washing dishes, showering or brushing your teeth – the water runs much longer than necessary.

Water is the basis of existence

Water is the basis of existence for all life on this planet. More than two-thirds of its surface is covered with water, but only a tiny fraction of it can be used by humans. Useful, clean water is getting scarcer. According to the World Health Organization (WHO), in 2012 around 783 million people did not have sufficient access to clean drinking water.

In any case, the handling of water can not be called sustainable. The straightening of rivers hurts the ecosystem enormously. Also, the ability to pump water through man-made piping systems and thereby use dry soils as arable land has harmed nature extensively. Both the Aral Sea and the Dead Sea, from whose tributaries water is drained, are gradually drying up. Source: Planet Knowledge

Of course, we do not have any of the water from the Aral Sea or the Dead Sea – but if you read that 1/3 of the world’s largest groundwater reserves are acutely endangered, you should at least start thinking …


Beekeeping At School

Beekeeping At School

Schulimkerei hat mit der Imkerei in der Schule begonnen. Das erste eigene Projekt der Schulimkerei findet an der Adolf-Kußmaul Grundschule in Graben-Neudorf statt. Kinder der vierten Klasse nehmen hier an einer Imker AG teil, die ihnen ein Gefühl dafür gibt, mit Bienen umzugehen.


beekeeping at school

Sie lernen, dass der Umgang mit Bienen sehr viel Freude macht, wenn sie sich den Tieren richtig nähern. Sie lernen auch über die Bedeutung der Bienen für unser tägliches Leben. Dazu gehört zu erfahren, welche Lebensmittel uns ohne Bienen nicht zur Verfügung stünden. Die Grundkenntnisse der Imkerei werden vermittelt und damit ein Verantwortungsgefühl für die Umwelt und Respekt vor der Natur.

Hier, wie später auch an anderen Schulen, ist es Ziel, dass die Kinder durch die Imkerei in der Schule an Bienenstöcken praktisch den Umgang mit Bienen selbst erforschen und sowohl ihren ökologischen, als auch den ökonomischen Nutzen erkennen. Wir finden landwirtschaftlich Flächen, die sich für die Anlage von bienenfreundlichen Blumenwiesen anbieten. Dort zeigen wir den Kindern, wie sie zu größerer Biodiversität beitragen können.

In theoretischen Unterrichtsstunden werden sie mit Hilfe von Buch- und Internetrecherchen an Aufgaben herangeführt, die sie dann in der Praxis lösen. Bei dieser Gelegenheit weisen wir auch auf die Kooperation mit der Imkerin und Kinderbuch Autorin Undine Westphal hin. Sie steht uns bei unserem Schulprojekt mit Rat und Tat zur Seite.

Umweltbewusstsein gehört zu den wichtigsten Themen für die Zukunftsgestaltung der Kinder. wird einen wichtigen Beitrag dazu leisten. Nachhaltigkeit und Umweltverantwortung muss ein zentrales Anliegen für junge Menschen werden. Man kann nicht früh genug damit beginnen.

Honey against Infections


Honey against Infections

The best-known and most widespread use of honey in the field of bronchial diseases, ie cough, runny nose, hoarseness, is the proven home remedy: warm milk with honey. Here, the emphasis is on the word ‘warm’, because the milk should not be warmer than 35 – 40 degrees, otherwise all enzymes and beneficial ingredients of honey would be destroyed by the excessive heat.
In a very old study in 1970, more than 500 patients with chronic bronchitis and about 300 asthmatic patients were treated with the following treatment: The respiratory tract was treated with a honey atomizer via the mucous membranes. In addition, the patients had honey for slow dissolution in the mouth. More than 400 of the brochitis patients were virtually symptom-free after 14 days, and about 270 of the asthma patients felt a significant improvement in their condition after the same treatment.
In the last 10 years alone, about 30 studies have dealt with this topic. American studies from 2010 and 2011 compared conservative treatment with honey-treated children to pertussis and showed that honey had significantly better healing effects than traditional methods and, as has often been emphasized, without significant side effects. In addition, the quality of sleep of sick children and their parents improved. A very ‘simple’, but extremely effective method of making known and employing patients with products from the hive is the so-called Porpolair device, in which propolis and / or propolis aerosol oils are vaporized and released into the ambient air. The enriched air is somewhat reminiscent of beehive air, making breathing much freer and promoting the well-being of patients with respiratory diseases.

Apilarnil – the least known bee product

Apilarnil – hormones against fatigue

Apilarnil is the least known bee product and was discovered by the Romanian apitherapist Nicolae V. Iliesiu.
This is an extract of the entire contents of 7 day old drone cells, i. Both the 7-day-old drone larvae and the nutrients in the cells such as honey, pollen and propolis are used. For the production, the cells are comminuted as a whole, homogenized, filtered and freeze-dried. It can be kept for several months at -5 to -20 degrees.

The chemical composition

Like royal jelly, Apilarnil consists of 65-75% water, the rest dry substances, proteins, carbohydrates, lipids (fats), hormones, 19 different amino acids, vitamins A, B1, B2, B6, C, D as well as minerals and Trace elements such as calcium, phosphorus, zinc, selenium, iron.


Overall, the ingredients are similar to those of royal jelly, but the high proportion of male hormones allows for other indications. Apart from the fact that the product because of its nutrients, vitamins and sex hormones is a kind of concentrated feed for humans and animals, it is particularly suitable for ill and weakened people as an energy donor because of its easy digestibility. As Nicolae Iliesiu, who discovered the Apilarnil more than 30 years ago, in his 1991 published in Romania book ‘Apilarnil’ published in various Romanian clinics studies show, there are also healing successes with Apilarnil (often in combination with others Bee products applied) at:
all kinds of states of exhaustion
Metabolic diseases such as diabetes, gout
mental and emotional depression caused by the aging process
Immune system weaknesses (infections, influenza infections)
Impairment of the neuro-vegetative system
Erectile Dysfunction
Dysfunctions of the endocrine system
Menopausal symptoms

beeswax therapy as an alternative treatment

Another not unpleasant bee product application is beeswax therapy.
For the relief of coughs, colds, cold and inflammatory pains of the muscles and tendons and degenerative, traumatic joint diseases beeswax is used alone or enriched with propolis (5-10%). Upon heating, the wax absorbs heat, which is then released to the tissue during use on the body. On the one hand, the skin is able to absorb wax active ingredients and on the other hand to extract toxins and waste products and other waste products from the tissue, so that it is possible to speak of a healing effect during the use of wax. On the other hand, however, the developing body heat of a wound application leads to healing processes.
To use wax, you have at least two options: Either use wax plates, as they are also used by beekeepers for middle walls. These can be purchased in prefabricated shops of beekeepers in 1 kg packages as ready-made plate goods, also in organic quality, or you get the appropriate block product, especially if the wax is to be liquefied. An alternative is provided by the company Wickel & Co., which has been dealing with beeswax and all related equipment for over 20 years and has received a whole series of patents in this area. It is particularly worth mentioning that this beeswax is absolutely free of residues or chemical substances that actually do not belong in the wax. A wax plate can be gently warmed slightly without melting, then placed immediately on the body to be treated and covered with a good cotton, nettle or linen cloth, so that the heat can last longer.
If you want to liquefy the wax, it must be melted in a water bath and while it is still warm 2-3 cm high in flat vessels to be poured. The wax changes very quickly from the liquid to the solid state. Therefore, it should, as long as it is still warm, taken out of the vessel and applied to the body and covered with a cloth.
Or: Immerse gauze compresses in the liquefied wax, then place them, slightly cooled, on the sick spot and cover them with a cloth.
The treatments should take about 15 – 20 minutes.
If you want to create a wax plaster, cut a piece of nettle or linen cloth to the required shape and size, dip it in the melted wax and add propolis. After cooling, this piece is re-heated slightly, then applied to the sick spot for 12-24 hours and covered with a cloth.

Duty of Care for Beekeepers

Duty of Care for Beekeepers

Sorgfaltspflicht der Imker

Inzwischen hat viele Informationen zu Bienen, zum Bienensterben zur Bienenrettung und zum Imkern veröffentlicht. Dabei haben wir immer wieder unsere Philosophie der Nachhaltigkeit betont und auf die Wichtigkeit des Umweltbewusstseins hingewiesen. Dieses Bewusstsein sollte bei unserem Denken und Handeln immer im Vordergrund stehen. Dazu gehört auch die Sorgfaltspflicht der Imker. Es ist uns klar, dass es oft schwierig ist, neue Denkweisen mit alt eingefahrenen Strukturen zu vereinbaren. Allerdings muss man immer offen sein für Neuerungen, wenn man nicht zum ‘alten Eisen’ gehören möchte. Und wer will das schon..? Reden wir hier also einmal über die Sorgfaltspflicht der Imker…
Wenn wir über eingefahrene Strukturen beim Imkern sprechen, denken wir zunächst an Bienenhaltung und Honigernte. Denken wir aber auch an die Sorgfaltspflicht bei der Imkerei? Haben wir immer im Hinterkopf, was das Wichtigste ist – nämlich die Gesundheit und das Wohlergehen der Bienen?
Wenn wir es einmal genau analysieren, behandeln wir häufig die Bienen nicht anders, als Landwirte ihre Kühe, Hühner und Schweine. Sie sind Einnahmequellen und sichern unseren Unterhalt. Der Profit steht klar im Vordergrund. Dann kommt das große Lamento: Die Bienen sterben. Natürlich sind Parasiten und Pestizide Schuld.

Was tun wir aber, um unsere Bienen davor zu schützen? Wir nehmen ihnen den Honig, der ihnen Kraft verleiht und ihr Immunsystem stärkt, um ihn durch Zuckerwasser zu ersetzen. Das entspricht nicht der Sorgfaltspflicht. Mit einem guten Immunsystem könnten die Tiere sich viel besser schützen und würden möglicherweise nicht massenhaft sterben.

Duty of care for beekeepers

Mit eingefahrenen Strukturen meinen wir, dass wir Imker oft nicht über den Tellerrand hinausblicken. Wir denken kurzfristig und berücksichtigen nicht, dass auch der Honigertrag sich nicht reduzieren würde, wenn wir besser mit den Bienen umgehen würden. Bienensterben verursacht höhere Verluste als der Verzicht auf einen Teil der Ernte.
Wir haben über Erfahrungen der Imker gelesen, die diese Tatsache bei ihrer Arbeit berücksichtigen und nur profitieren. Wir sollten es alle einmal versuchen!
Es gibt einiges mehr zu beachten, worüber wir im nächsten Blog berichten.
