Summer Eczema in Horses: Black Cumin & Zeolite as a Natural Solution

Sweet itch in horses is one of the most common and distressing skin conditions in horse keeping – and for many horse owners, it is an annual recurring topic full of worry, grooming effort, and the desire for genuine relief. It is estimated to affect 5–10% of all horses in Central Europe, especially Icelanders, Friesians, and Shetland ponies. The cause is an allergic overreaction to the saliva of Culicoides midges – with the well-known consequences: severe itching, rubbing, hair loss, and open sores.
The good news: with the right combination of protection, adapted feeding, and nature-based supplements such as organic black cumin and zeolite, the midge season can be made significantly more relaxed for many horses – from the inside and the outside. The challenges that horses and their owners face in summer are well explained in the article: Horses in summer - How to correctly use heat, insects & zeolite.

1. Sweet itch in horses – Causes and what is really behind it

Sweet itch is a common skin condition that affects many horses. It is an allergic reaction to the saliva of biting midges, particularly of the Culicoides species. These midges are especially widespread in warm regions and often appear during the summer months. The condition causes severe itching, skin redness, swelling, hair loss, and open wounds in affected horses.

The midge bites trigger an allergic reaction in the horse's immune system, leading to inflammation and skin irritation. Some horse breeds, such as Shetland ponies and Icelandic horses, are more susceptible to sweet itch due to genetic predisposition.

In recent years, the use of black cumin and zeolite has emerged as a potential solution for alleviating the symptoms of sweet itch in horses. Black cumin has anti-inflammatory and anti-allergic properties, while zeolite can contribute to detoxifying the body and supporting the immune system.

In this blog, we will take a closer look at the use of black cumin and zeolite and explain how they can help reduce the symptoms of sweet itch and improve your horse's well-being. We will also provide tips on preventing sweet itch and share testimonials from horse owners who have successfully used these natural approaches.

2. Sweet itch in horses: Causes, symptoms, and effects

Sweet itch, also known as summer eczema or summer dermatitis, is a dermatological condition that affects horses. It is caused by an allergic reaction to the saliva of certain midge species, especially Culicoides midges. These midges are known for their small, biting stings, which trigger a hypersensitive immune response in some horses.

The causes of sweet itch are diverse. It is assumed that genetic predisposition plays a role, as certain horse breeds are more sensitive to midge bites. Furthermore, environmental factors such as high humidity, warm temperatures, and a high number of midges in the area can increase the risk of sweet itch.

The symptoms of sweet itch are usually unmistakable. The most common ones include intense itching, skin redness, swelling, hair loss, and the appearance of open wounds. Horses with sweet itch tend to rub themselves more, which can lead to further skin injuries. The itching and skin irritation can cause significant discomfort for the horse and even lead to infections if the skin is damaged.

The effects of sweet itch on a horse's well-being can be significant. In addition to obvious physical discomfort, sweet itch can also lead to stress, irritability, and behavioral changes. Constant distraction due to itching and restlessness can negatively impact the horse's concentration and performance. Therefore, it is important to take effective measures to alleviate symptoms and improve the horse's quality of life.

In the next section of our blog, we will take a closer look at the potential benefits of black cumin and zeolite in the treatment of sweet itch in horses.

Why the combination of black cumin and zeolite makes sense

Black cumin and zeolite act on different levels – and therefore complement each other well.
Black cumin press cake contains essential oils, fatty acids, and the active ingredient thymoquinone. Studies show this to be anti-allergic, anti-inflammatory, and immunomodulatory – addressing exactly where sweet itch originates: the immune system.
Clinoptilolite zeolite acts purely physically in the digestive tract. It binds toxins, mycotoxins, and ammonium before they enter the blood – thereby relieving the body from the inside. A less burdened organism tends to react more calmly to external stimuli like midge bites.

The combination of both substances in one product has a practical background: many horse owners were feeding both components in parallel anyway. A joint powder simplifies dosing and ensures that both substances are given daily and in the correct quantity.

Important: Organic quality for black cumin is not a marketing argument, but has a specific reason. Pesticide residues in conventionally grown black cumin can trigger allergic reactions themselves – exactly the opposite of the desired effect. For sensitive horses with sweet itch, this is particularly relevant.

3. Treating sweet itch in horses naturally – 5 proven methods

In addition to using black cumin and zeolite, there are other natural methods that can help in the treatment of sweet itch in horses. Here are some of them:

1. Dietary adjustments: Nutrition plays an important role in treating sweet itch. A balanced, nutrient-rich diet can strengthen the immune system and support skin health. It is recommended to choose low-sugar and low-carbohydrate feeds, as increased sugar intake can raise the risk of inflammation and allergies. Adequate supply of omega-3 fatty acids, antioxidants, and vitamin E can also be helpful. It is best to consult a veterinarian or nutritionist to create a suitable diet for your horse.

2. Skin care: Good skin care is crucial to alleviate the symptoms of sweet itch. Regularly washing the affected areas with mild, hypoallergenic shampoos or special skin care products can help remove dirt and allergens. It is important to dry the skin thoroughly afterwards to avoid moisture accumulation. Applying soothing and moisturizing lotions or ointments can also help reduce itching. At this point, we recommend the zeolite skin powder with organic lavender.
Easy to apply, 100% natural.

3. Insect protection: Since sweet itch is caused by midge bites, effective insect protection is crucial. Use insect repellents specifically designed for horses to ward off midges. Fly rugs with fine-meshed fabric can also help prevent midges from getting through. Ensure that you regularly clear the stable and pasture of standing water and other midge-control measures to reduce the midge population. And start in the stable with litter with zeolite.

The high-quality feed lime with zeolite and organic herbs reduces flies and midges even in the stable.

4. Homeopathic or herbal preparations: There are various homeopathic or herbal preparations that can help alleviate itching and inflammation. These include, for example, aloe vera gel, tea tree oil, or calendula ointment. It is important, however, to use such products only after consultation with a veterinarian or a naturopathy specialist to ensure that they are suitable for your horse and do not cause unwanted side effects.

5. Stress management: Stress can worsen the symptoms of sweet itch. A stress-free environment and good care can help reduce stress in your horse. Regular exercise, turnout, social interaction with other horses, and a calm atmosphere in the stable can contribute to improving your horse's well-being.

What is black cumin and how does it affect horses?

Black cumin, also known as Nigella sativa, is a plant native to various parts of the world, particularly the Middle East. Black cumin seeds have been used for many centuries in both cooking and traditional medicine. They are rich in essential oils, proteins, fatty acids, and various other bioactive compounds.

Black cumin oil is frequently used as a nutritional supplement for horses, especially in the treatment of sweet itch. It has a variety of potential health benefits due to its anti-inflammatory, antioxidant, immunomodulatory, and anti-allergic properties.

The anti-inflammatory properties of black cumin can help to reduce inflammatory responses in the skin during sweet itch. It can soothe itching, reduce skin redness and swelling, and help the horse to rub less, resulting in less skin damage.

Furthermore, black cumin oil can also have an immunomodulatory effect by supporting and strengthening the horse's immune system. This can help to reduce the overreaction of the immune system to midge bites and thus mitigate the allergic reactions that cause sweet itch.

It should be noted that while black cumin can be helpful for many horses, reactions and results may vary individually. Therefore, it is advisable to begin using black cumin oil in consultation with a veterinarian or animal health practitioner and to observe your horse's reactions.

Black cumin keeps midges away

A remarkable feature of black cumin is its ability to emit a scent that keeps midges away. While the oil has a pleasant and spicy smell to us humans, midges seem not to like this scent at all. It is as if the black cumin creates a natural barrier that repels these annoying insects. This fragrant protective shield can be used by horses to protect themselves from the annoying midge bites that cause sweet itch. It is amazing to observe how the horses radiate a subtle hint of this unique aroma, which creates an aura of defense around them. This natural defense against midges makes black cumin oil a promising solution for horse owners who want to protect their beloved four-legged friends from the tormenting itching and symptoms of sweet itch.

Please note that experiences with the smell of black cumin oil and its effect on midges can vary individually. It is possible that the smell is perceived slightly differently from horse to horse. It is recommended to observe your horse's reactions. Steinkraft also offers smaller sample packs. Order now and try out this wonderful product.

Sweet itch in horses experiences – what horse owners report

"I had been struggling with my mare's sweet itch for years.

The symptoms were truly tormenting for her - constant rubbing, itching, and inflamed skin patches. I tried everything possible, but nothing seemed to really help until I came across Steinkraft and the black cumin-zeolite powder. I was skeptical, but I didn't want to leave any stone unturned. So, I started giving my mare a portion of black cumin and zeolite daily. Within a few weeks, I already noticed a significant improvement. Her itching subsided, the skin became calmer, and the inflammations healed. I have continued the treatment since then, and my mare's sweet itch is significantly under control. I am so grateful for these natural solutions that offer her so much relief." ⭐⭐⭐⭐⭐ Lisa M., Black Cumin Zeolite Powder

"My gelding struggled with sweet itch every year and I was really desperate.

Conventional treatment methods brought only limited success, and I didn't want to constantly give my horse strong medication. I decided to try natural approaches and came across Steinkraft and the black cumin-zeolite powder. I started adding it to my horse's feed daily and sprinkling the affected skin areas with zeolite powder. I was amazed by the results! My horse's sweet itch became less intense and the itching symptoms were significantly reduced. It was a relief to see my horse finally find peace and be able to enjoy the summer months again. I can really recommend this mixture when it comes to treating sweet itch in horses." ⭐⭐⭐⭐⭐ Tim B., Black Cumin Zeolite Powder and Tierkraft Zeolite Skin Powder

"After 10 years, the first summer WITHOUT A RUG

It is the goal of every horse owner to do something good for their darlings during the midge-plagued summer months. I am one of the proud owners of a Friesian mare, which is known to have major problems with sweet itch. They only get through the summer covered in rugs, which is a plague and anything but relaxing. Last year, I started a course with the black cumin-zeolite powder from Steinkraft with her at the beginning of May, and I must say, for the first time in 10 years, my horse managed without a summer rug. It's not that there are no bites at all, but they remained within limits and there were no open sores. It was manageable, and the horse was happy being a horse over the summer. This year, we started the black cumin-zeolite with all our horses at the end of April, combined for my Friesian mare with the zeolite skin powder from Steinkraft, which I applied to the mane crest and tail base, which has a soothing effect. So, from the inside and out. What I also highly recommend is using zeolite bedding, because it keeps biting midges and flies and everything that flies and crawls in check right in the stable. That is a good all-round package for a happy horse over the summer." ⭐⭐⭐⭐⭐ Tanja E., Black Cumin Zeolite Powder, Tierkraft Zeolite Skin Powder, Horsekraft Bedding

Clearly better coat health.

"Dodo was fed the black cumin-zeolite, and we were able to observe a positive effect on his coat. That means his coat is shinier and no longer so dull. The product also helped him super well through the coat change. Especially now from winter to summer. And he doesn't rub himself quite as much anymore. Therefore, not as many hairs are breaking off at the tail. And he has gotten a bit more forelock." ⭐⭐⭐⭐⭐ Patricia, Black Cumin Zeolite Powder

Effects of pesticides in black cumin oil

When choosing black cumin products for our horses, organic quality is of the utmost importance. Pesticides and chemical residues in conventionally grown black cumin can trigger allergic reactions and impair the delicate balance of the horse's body. We at Steinkraft place great value on the use of organic black cumin pomace. Organic cultivation ensures that the black cumin is produced without the use of pesticides or other harmful chemicals. This guarantees a pure and unadulterated quality that is of crucial importance for the health of our horses. With the Steinkraft black cumin zeolite pellets, you can be rest assured that you are giving your horse a product of the highest quality that is free from pesticide residues and optimally utilizes the natural benefits of black cumin. Choose organic quality and ensure that your horse benefits from the best ingredients - for healthy and allergen-free care.

Health practitioners tell me again and again about medicinal herbs and so-called superfoods that then trigger allergies in horses. You want to do something good, and the opposite is the case. The pesticides disrupt the harmony of the horse's body, and perhaps it is then even a good reaction from the animal with the statement: that is not good for me; you see that I am reacting allergically to it.

How is the Steinkraft Black Cumin Zeolite Powder dosed?

The dosage of the Steinkraft black cumin zeolite powder depends on the horse's weight. As a rule, it is mixed into the horse's regular feed daily as a dietary supplement. With some horses, you have to sneak it in, while others eat it very gladly. One thing seems very consistent: horses that do not like black cumin oil will readily eat this powder mixture. And that is a blessing.

Our tip: we have small trial tubs (100g) - here you can test once if it meets their taste.

How long does it take until you see results when using the Steinkraft black cumin zeolite powder?

Results can vary individually, as every horse is unique. Some horses react really quickly to the powder and show an improvement in symptoms after just a few weeks. For other horses, it may take a little longer until the positive effects become visible. It is recommended to give the powder continuously over a longer period to achieve optimal results. And also to build up a depot in the body. If you haven't detoxified your horse for a long time, then add zeolite for two months beforehand; then everything is more effective.

Can you give Steinkraft Black Cumin Zeolite Powder without hesitation together with mineral feed?

In general, the Steinkraft black cumin zeolite pellets are well tolerated and can usually be given without problems together with mineral feed. However, it is recommended to consider the total dosage of the supplements and consult a veterinarian if necessary. Every horse has individual needs, so it is important to consider specific requirements and possible interactions with other supplements.

Since when has black cumin been used for horses?

The use of black cumin oil for horses has a long history that goes back centuries. Black cumin oil was already used in the traditional medicine of ancient Egypt, Greece, and the Middle East to treat various health problems.

There is no precise information about who discovered black cumin oil specifically for horses, as the use of black cumin oil in veterinary medicine is based on empirical values and traditions. Over time, horse owners and caretakers have recognized the positive effects of black cumin oil on the health and well-being of their horses and have used it as a natural supplement to support the immune system, skin health, and for various ailments.

Nowadays, black cumin oil is used by many horse owners and veterinarians as a natural alternative to support health and for specific needs of the horses.

We at Steinkraft use ORGANIC black cumin pomace to produce the product HORSEKRAFT Zeolite Black Cumin Powder. This press cake contains all the valuable ingredients of black cumin, but it no longer contains any oil that could go rancid. We think that's great! And many horses do too.

FAQ: Sweet Itch in Horses

❓ What is sweet itch in horses? Sweet itch is an allergic skin disease in horses, triggered by the saliva of Culicoides midges. The immune system reacts hypersensitively to the midge saliva, leading to severe itching, skin redness, hair loss, and rubbing. Icelandic horses, Friesians, and Shetland ponies are particularly frequently affected.

❓ When is the best time to start with black cumin for sweet itch? Ideally already in the spring – 4–6 weeks before the midge season begins. This allows a natural depot to build up in the body. Many horse owners start feeding it in April and don't stop until October.

❓ How long does it take for black cumin-zeolite to work for sweet itch? Results are individual. Some horses show improvement after just 2–3 weeks, while for others it takes 4–6 weeks for the effect to be noticeable. Continuous feeding throughout the entire midge season is recommended.

❓ Can black cumin and zeolite be given at the same time as mineral feed? Yes, both products are well-tolerated and can generally be given together with mineral feed without any problems. If giving medication simultaneously, we recommend a time interval of 2–3 hours.

❓ Which horse breeds are particularly susceptible to sweet itch? Icelandic horses, Friesians, Shetland ponies, and other pony breeds are particularly frequently affected. But warmbloods can also develop sweet itch – genetic predisposition plays a major role.

❓ Does zeolite bedding also help against mosquitoes in the stable? Yes – zeolite bedding binds moisture and ammonia, thereby removing the breeding ground for mosquitoes and flies. Many horse owners report significantly fewer insects in the stable since using zeolite bedding.

❓ Is ORGANIC black cumin important or is conventional sufficient? Organic quality is particularly important for black cumin for horses. Conventionally grown black cumin can contain pesticide residues, which can themselves trigger allergic reactions – exactly the opposite of the desired effect. STEINKRAFT uses exclusively organic black cumin cake.

Your horse doesn't have to suffer every summer. With the right preparation starting in spring – black cumin, zeolite, bedding, and skin powder as a holistic package – the midge season can become much more relaxed. For horse and human.
