How does it work?

There is a lot of natural power in Kalter Bruder ® . The unique, inimitable composition of the medicinal plants aloe vera, arnica, camphor, menthol and devil's claw has been perfected over many years in a small laboratory on Gran Canaria.

Kalter Bruder ® creates a cooling and relaxing effect from the very first application. Particularly stressed or cramped areas of the body benefit from the regenerating and circulation-promoting properties of the ingredients, which can provide relaxation like jumping into an ice bath . Typical areas of application for our customers are complaints such as restless legs, sports injuries, joint pain and polyneuropathy .

What's inside?

Kalter Bruder ® is made up of many herbal active ingredients and it is this sophisticated recipe that convinces many users. The basis is aloe vera, arnica, camphor, menthol and devil's claw.


Arnica, also known as Arnica montana, is a medicinal plant that has been used for centuries for its medicinal properties. It contains various active compounds such as flavonoids and essential oils that have anti-inflammatory and pain-relieving properties. Arnica is often used to treat injuries such as bruises, sprains, and sore muscles. It can also help relieve pain and swelling after surgery or tooth extractions. Arnica can be used in the form of ointments, gels, or tinctures. However, it is important not to apply arnica to open wounds or damaged skin. Allergic reactions can also occur, so an allergy test should be performed before use.


Strictly speaking, camphor itself is not a medicinal plant, but the ingredient of a medicinal plant - the camphor tree. Camphor is obtained from the wood and bark of the camphor tree.

When camphor is used externally, it can promote blood circulation and relax muscles. This has a particularly positive effect on restless legs and other affected areas of the body. In the past, the medicinal plant was used primarily to treat cold symptoms and was valued for its calming and circulation-promoting properties. In modern herbal medicine, camphor is mainly used to treat diseases associated with muscle or joint pain.


Menthol is a natural substance derived from mint oil. It has a cooling and pain-relieving effect and is often used in ointments, creams and inhalation products. Menthol can help with headaches, muscle and joint pain, as well as colds and respiratory problems. It also has anti-inflammatory properties and can relieve itching. However, menthol should not be applied to open wounds or irritated skin. It is important to observe the correct dosage and consider possible side effects such as skin irritation or allergic reactions. Overall, menthol is a natural option for relieving pain and discomfort, but should be used with caution.

Devil's Claw

Devil's claw, also known as harpagophytum, is a medicinal plant with anti-inflammatory and analgesic properties. It is often used to treat joint pain, arthritis and back pain. The active ingredients of devil's claw can reduce inflammation and improve joint mobility. The plant can be taken in the form of capsules, tablets or ointments or applied externally. However, it is important to observe the correct dosage and consider possible side effects such as stomach upset or allergic reactions. Devil's claw is a natural alternative for pain relief, but should not be used without consulting a doctor.

Aloe Vera

Aloe vera is a plant with many health benefits. It contains a variety of nutrients such as vitamins, minerals and enzymes that have anti-inflammatory and healing properties. Aloe vera is often used to treat skin problems such as sunburn, acne and skin irritations. It can also help relieve digestive problems such as heartburn and constipation. Aloe vera can be taken in the form of gel, juice or capsules. However, it is important to check the quality of the product and be aware of any possible allergic reactions. Overall, aloe vera is a natural and versatile plant that offers many health benefits.

Instructions for use

Kalter Bruder ® is a cooling cosmetic sports and massage gel for external use on the skin. It has proven particularly effective for restless and tingling legs , but it is also increasingly used for joint and muscle problems.

You can increase the cooling effect by keeping the gel in the fridge, washing your skin thoroughly beforehand (so that the oily film goes off) and then applying it particularly thickly. It can still be quite moist after you rub it in.

Exercises such as squats before use stimulate blood circulation and can enhance the positive effects.

The gel is quickly absorbed and can be applied several times a day - e.g. directly before going to bed.

The gel cools and stimulates blood circulation. This means that the typical urge to move can be satisfied from within.

Store closed in the original container in a dry and cool place. Protect from direct sunlight and high temperatures.

Please note the safety instructions.

Unglaublich, aber wahr 😊

Seit Jahren „kämpfe“ ich mit RLS. Zudem leide ich an den Füßen unter der Nervenkrankheit Polyneuropathie.
Seit ich Kalter Bruder verwende ist das RLS nachts kaum mehr ein Thema. Auch Schmerzen in den Fußgelenken werden verbessert.
Ich nutze Kalter Bruder abends vor dem ins Bett gehen nach Qigong und/oder nach einer heißen Dusche. Danke 🙏🏻

Frauke Burmester
Nach Skepsis völlig Positiv überrascht

Ich war erst sehr skeptisch 🤨 da ich unterschiedlich stark an restless legs Syndrom leide hat es mich bisher gut durch die Nächte gebracht , ich habe meine Medikamente vollständig abgesetzt und bin glücklich darüber, ich werde es auf jeden Fall wieder kaufen und weiter empfehlen .

Gel „Kalter Bruder“ , das Wundermittel für die Nacht !

Unglaublich , das Gel „ Kalter Bruder“ , wirkt wie ein Wunder !
Die stressgeplagten Nächte sind vorüber, ich kann wieder ohne unruhige Beine und das ständige Herumlaufen schlafen . Super ! Danke !

Produkt der Extraklasse!

Bei der Diagnose RLS ist man ja ziemlich auf sich allein gestellt. Man forscht im Netz und stößt plötzlich auf dieses Gel. Natürlich muß es sofort ausprobiert werden, und............ es hat sich gelohnt! Es ist für mich eine große Hilfe.Ich schlafe zwar die Nacht nicht durch. Massiere auch mind. 2x damit meine Beine. Aber die Beschwerden ( heiße Beine, vor allem sind die Unterschenkel betroffen ) sind nun gut auszuhalten. Allerdings unterstütze ich die Behandlung mit einer DMSO Mischung. Diese hat ja bekanntlich eine Kanalfunktion und läßt das Gel besonders gut einwirken.
Bin also begeistert und werde als Kundin treu bleiben.

Einfach toll

So viele Dinge habe ich schon ausprobiert, nichts hat langfristig geholfen. KALTER BRUDER steht jetzt auf meinem Nachttisch.

Doris Purwin

Bis auf einige Male bin ich zufrieden und hoffe, nach einiger Zeit meinen Tablettenkonsum reduzieren zu können.

Dieter Dernovsek

Wir sind mit dem kalten Bruder sehr zufrieden und können gut durchschlafen. Und haben festgestellt das man Schulter und Gelenk schmerzen auch gut lindern kann.

Kalter Bruder=heißer Tip

Ich benutze das Gel jetzt schon einige Wochen und kann sagen es hilft. Habe gerade wieder eine Zappel Attacke bekommen, Gel aufgetragen und nach ca. 5-10 Minuten wird es deutlich besser und ein angenehmes Gefühl von Kälte und Entspannung macht sich bemerkbar. Da meine RLS Probleme sehr stark Schmerzbezogen sind wirkt es halt nicht immer. Ich bleibe aber dran und werde weiter berichten.

Total begeistert

Meine Frau und ich leiden beide unter RLS und machen seit über zehn Jahren Yoga vor dem Zubettgehen. Das Gel bekamen wir vor drei Monaten und wir waren sofort begeistert – es entspannt die Beine und ich habe seltener Muskelkater.
