Polyneuropathy – when nerves become a daily burden
Tingling, burning, stabbing pain – especially in the feet, legs or arms. Polyneuropathy affects millions of people in Germany. The symptoms often appear at night or during rest and significantly reduce quality of life. Many patients have been through a long journey of pain, medications and side effects – often without relief.
Cooling can offer targeted support: it slows nerve signals, calms overactive nerve pathways, reduces inflammation and shifts the brain’s focus away from pain. The gate control theory also explains why cold can help: it blocks pain signals by overriding them with cooling sensations.
The good news: Cooling often brings immediate relief – without medication. That’s where Kalter Bruder® comes in.

Kalter Bruder® is a natural cooling gel developed specifically for people with polyneuropathy and nerve-related pain. Its plant-based formula combines menthol, camphor, aloe vera, arnica and devil’s claw, known for their cooling and calming effects.
