Extracts from Butterbur are an Effective Non-Drowsy Treatment for ’Hay Fever’

22.08.2005


The largest trial so far conducted using Butterbur extract to treat intermittent allergic rhinitis (hay fever) shows that this plant extract is as effective as a commonly used antihistamine (Telfast 180).



In recent years there have been a few reports of small research trials that give a mixed view about the effectiveness of Butterbur extract for treating intermittent allergic rhinitis (IAR). Now researchers from Germany and Switzerland have published results from a randomised, double-blind, parallel group comparison study involving 330 patients in 11 centres. They found that treatment with butterbur extract was as effective at combating symptoms of IAR as treatment with a conventional antihistamine (Telfast 180). In addition they found that Butterbur extract did not cause drowsiness.

‘Despite being a herbal drug, Butterbur Ze339 has now been subject to a series of well controlled trials and should be considered as an alternative treatment for IAR,’ says lead researcher Andreas Schapowal.


Butterbur (Petasites hybridus) is a plant found throughout Europe and Asia and parts of North America. The roots of this plant have been used in herbal remedies for centuries while the leaves have only been introduced recently as a new herbal medicine. An extract can inhibit the body’s ability to produce leukotrienes, biomolecules that are involved in the inflammatory response to allergens. They also help stimulate the body’s production of prostaglandins, chemicals that play a role in reducing inflammation.

Finding an alternative therapy for IAR is important partly because up to 20 per cent of people living in Western countries suffer from it.

‘Because Butterbur does not cause the sort of drowsiness that is so often associated with other anti-histamines it could be particularly useful for patients who can not tolerate other therapies,’ says Schapowal.

Im Focus: Designing Architecture with Solar Building Envelopes

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.

As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...

Im Focus: How to inflate a hardened concrete shell with a weight of 80 t

At TU Wien, an alternative for resource intensive formwork for the construction of concrete domes was developed. It is now used in a test dome for the Austrian Federal Railways Infrastructure (ÖBB Infrastruktur).

Concrete shells are efficient structures, but not very resource efficient. The formwork for the construction of concrete domes alone requires a high amount of...

Im Focus: Bacterial Pac Man molecule snaps at sugar

Many pathogens use certain sugar compounds from their host to help conceal themselves against the immune system. Scientists at the University of Bonn have now, in cooperation with researchers at the University of York in the United Kingdom, analyzed the dynamics of a bacterial molecule that is involved in this process. They demonstrate that the protein grabs onto the sugar molecule with a Pac Man-like chewing motion and holds it until it can be used. Their results could help design therapeutics that could make the protein poorer at grabbing and holding and hence compromise the pathogen in the host. The study has now been published in “Biophysical Journal”.

The cells of the mouth, nose and intestinal mucosa produce large quantities of a chemical called sialic acid. Many bacteria possess a special transport system...

Im Focus: Repairing defects in fiber-reinforced plastics more efficiently

Fiber-reinforced plastics (FRP) are frequently used in the aeronautic and automobile industry. However, the repair of workpieces made of these composite materials is often less profitable than exchanging the part. In order to increase the lifetime of FRP parts and to make them more eco-efficient, the Laser Zentrum Hannover e.V. (LZH) and the Apodius GmbH want to combine a new measuring device for fiber layer orientation with an innovative laser-based repair process.

Defects in FRP pieces may be production or operation-related. Whether or not repair is cost-effective depends on the geometry of the defective area, the tools...
