What does the name Kalter Bruder® stand for?
The name Kalter Bruder® stands for our intensive cooling gel, developed by twin brothers with restless legs from Lüneburg, Germany. With its unique combination of relaxing and pain-relieving medicinal plants and a long-lasting, deep cooling effect, Kalter Bruder® provides noticeable relaxation for restless legs, polyneuropathy and joint pain.
Relieve joint pain effectively.
Joint pain is a common problem, but the causes and treatment options vary greatly - and are often misunderstood. Conditions such as gout, rheumatism or bursitis affect many people and require individually tailored treatments - but they all have one thing in common: targeted cold applications can combat acute inflammation, reduce swelling & relieve pain. However, the wrong application can aggravate symptoms, which is why cold therapy should only be applied to inflamed joints. However, the right diet, exercise and drug therapies are also crucial for success - in consultation with a doctor, of course.
If cold application is advised, the first question is the desired intensity and duration. There are a variety of options here - from ice baths to classic cold packs and alternating baths. For everyday use, expensive and complicated cryogenic devices and cold chambers are of course out of the question. Cold compresses, cold compresses and showers are easy to use, but their cooling effect usually only lasts for a short time. A cooling gel combines the benefits of an intensive and long-lasting cooling effect with simple and targeted application.
