Research shows heat in chili peppers can ease sinus problems
Hot chili peppers are known to make people "tear up," but a new study led by University of Cincinnati allergy researcher Jonathan Bernstein, MD, found that a nasal spray containing an ingredient derived from hot chili peppers (Capsicum annum) may help people "clear up" certain types of sinus inflammation.
The study, which appears in the August 2011 edition of Annals of Allergy, Asthma & Immunology, compares the use of the Capsicum annum nasal spray to a placebo nasal spray in 44 subjects with a significant component of nonallergic rhinitis (i.e., nasal congestion, sinus pain, sinus pressure) for a period of two weeks.
Capsicum annum contains capsaicin, which is the main component of chili peppers and produces a hot sensation. Capsaicin is also the active ingredient in several topical medications used for temporary pain relief. It is approved for use by the U.S. Food and Drug Administration and is available over the counter.
"Basically, we concluded that the spray was safe and effective on non-allergic rhinitis," Bernstein says of the study which showed that participants who used a nasal spray with Capsicum reported a faster onset of action or relief, on average within a minute of using the spray, than the control group.
Non-allergic rhinitis is an upper respiratory condition not caused by allergies but instead caused by environmental factors such as weather, household chemicals or perfumes; however, there are some people who have no triggers or don't know what triggers are causing the inflammation, Bernstein says.
This is the first controlled trial where capsaicin was able to be used on a continuous basis to control symptoms. It is considered a significant advance, "because we don't really have good therapies for non-allergic rhinitis," says Bernstein, adding that in previous trials the ingredient was too hot to administer without anesthesia.
The study was funded by Dynova Laboratories. Bernstein, a professor in the division of immunology, allergy and rheumatology at the UC College of Medicine, is a paid consultant for Dynova.

An international team of scientists has proposed a new multi-disciplinary approach in which an array of new technologies will allow us to map biodiversity and the risks that wildlife is facing at the scale of whole landscapes. The findings are published in Nature Ecology and Evolution. This international research is led by the Kunming Institute of Zoology from China, University of East Anglia, University of Leicester and the Leibniz Institute for Zoo and Wildlife Research.
Using a combination of satellite and ground data, the team proposes that it is now possible to map biodiversity with an accuracy that has not been previously...
Heatwaves in the Arctic, longer periods of vegetation in Europe, severe floods in West Africa – starting in 2021, scientists want to explore the emissions of the greenhouse gas methane with the German-French satellite MERLIN. This is made possible by a new robust laser system of the Fraunhofer Institute for Laser Technology ILT in Aachen, which achieves unprecedented measurement accuracy.
Methane is primarily the result of the decomposition of organic matter. The gas has a 25 times greater warming potential than carbon dioxide, but is not as...
Hydrogen is regarded as the energy source of the future: It is produced with solar power and can be used to generate heat and electricity in fuel cells. Empa researchers have now succeeded in decoding the movement of hydrogen ions in crystals – a key step towards more efficient energy conversion in the hydrogen industry of tomorrow.
As charge carriers, electrons and ions play the leading role in electrochemical energy storage devices and converters such as batteries and fuel cells. Proton...
Scientists from the Excellence Cluster Universe at the Ludwig-Maximilians-Universität Munich have establised "Cosmowebportal", a unique data centre for cosmological simulations located at the Leibniz Supercomputing Centre (LRZ) of the Bavarian Academy of Sciences. The complete results of a series of large hydrodynamical cosmological simulations are available, with data volumes typically exceeding several hundred terabytes. Scientists worldwide can interactively explore these complex simulations via a web interface and directly access the results.
With current telescopes, scientists can observe our Universe’s galaxies and galaxy clusters and their distribution along an invisible cosmic web. From the...
