20 Keep Cool for Horses

Rated 4.91 out of 5 based on 11 customer ratings
(16 customer reviews)


Riding an excitable horse in a competition or on a trail ride just isn’t as fun or productive as riding one who has his wits about him. #20 Keep Cool contains herbs known as “nervines,” which maintain a normal nerve impulse in the animal. Thus, you might find #20 Keep Cool helpful in maintaining a calm, cool horse who still knows where his feet are – a state enjoyed by the horse as much as the rider. This formula may be beneficial in supporting the overall nervous system in your horse, and in:

  • For behavioral problem management
  • Helping maintain contentment during separation, travel, and tension caused by changes in the daily routine
  • May also help curb destructive behavior

Note: This herbal combination contains Black Cohosh and should not be used on mares that are in the third trimester of pregnancy as this may cause hemorrhage during foaling. This product also contains Valerian Root, which is a prohibited substance on some venue testing requirements.

    My mustang got so nervous out on trails alone that I couldn’t ride him there unless there was another horse behind him. He even took off with me one day back to the barn and I had to bail off. I don’t always have someone to ride out with so I decided to try the Kool and WOW…He is literally a different horse. Doesn’t make him sleepy but sure does keep him cool and calm. I am able to ride out alone now with no further issues. Thanks for such a great product!!! I am using several other herbs for this horse and my dogs as well. I take them too!!

    My performance bred Quarter Horse gelding is well broke, but he has flight issues when not ridden regularly. I used Keep Cool as recommended this late fall at a large rodear (LOTS of riders & cattle with lots of commotion)
    and he never got flighty. He was focused and calm. I highly recommend Keep Cool!

    I am so thankful for this product, it was literally the difference between keeping and selling one particular horse. It helped with behavioral issues, including self mutalation.

    We bought a pony that had been traumatized by young boys. He would tremble when adults would get near him.

    I had some Keep Cool 20 from a previous horse and started the pony on it. He has made a dramatic change in one week. You can see the change his eyes after 30 minutes. This is the perfect time to train him to be confident.

    I felt the calming change in the horse but the pony is more dramatic. Maybe it is because he was so traumatized and the calming effect is so drastic.

    I am extremely happy with the effects of Silver Lining Herbs. It gives me confidence to use the other products, as well.

    This stuff works like nothing else on the market! I’ve tried lots of “calming” supplements and nothing compares to this price or efficiency wise! Will continue to be a customer forever!

    Our 13 year old gelding “Elmo” is a Sand Peppy Badger. My husband has excellent training techniques( has been training his horses since he was very young) and has been bringing Elmo along so I can use him for barrels. Elmo is a very sweet, loving, respectful boy; however, he had started to get spooky/apprehensive at things like banners hanging on the arena fences, tarps and he even started to go backwards on me when I was walking him toward a barrel in our arena that he has been looking at for 13 years (all his life). My husband took him back to some basic training techniques, which just did not seem to get him past being spooky. My husband said he wanted to get rid of him, but I was just sick over the thought, and suggested he contact SL for suggestions. Well, just after 3 days on Keep Cool #20, he was not as tense, after two weeks on it, he now has the confidence to actually walk up and investigate what has caught his attention, he steps back a step or two, then will approach it again, and within a few seconds, you can actually see his body relax, and he drops his head and starts to accept the scary item. I noticed he is also starting to focus on his job of turning the barrels and he is starting to trust me; have confidence in me as his rider. So we are very please with their recommendation of #20 Keep Cool, and I am adding #41 Equine oil, to use during competition just to keep his focus and take any additional stress off of him, until he has been going down the road and gets exposure to all different types of arenas for at least a year. We think the Sand Peppy Badger breed lends itself to having quirky traits. We have had some friends who were great hands that got rid of their Badgers because they just got tried of dealing with the drama. I can’t thank SL enough for providing a healthy alternative product so Elmo and I can start for filling my dream of running barrels again.

    I have an eighteen year old gelding that I was showing in cutting, who was diagnosed with pre-cataracts in 1995. Last year I was forced to retire him, as his eyesight had deteriorated so badly, especially in his right eye. I met Mickey at a cutting in Baker City, Oregon last summer (2000) and told him that not only was my horse losing his ability to see, but was becoming extremely agitated in the process. We put him on the #20 Keep Cool and the #21 Bright Eyes. His disposition became much better and last month I had his eyes reexamined because it seemed like he was seeing more. His left eye was completely clear and his right eye showed only a slight trace of cloudiness but the lens was clear. I had his shoes put back on him and am riding him again. Not cutting but certainly have not ruled that out. Dear Silver Lining: As a follow up to the letter I sent you a few months ago, I wanted you to know that I am once again cutting on Amos Malfec. Amos was diagnosed with cataracts and was almost blind in his right eye. His disposition became extremely agitated and I was forced to retire him from any riding. We put him on the Bright Eyes, and the Keep Cool for eight months. As his disposition improved, so did his eyesight. As I reported to you several months ago, upon his last exam, the cataracts are gone. I am back to cutting on him and he is teaching a nine year old girl to ride. I have my old friend back, completely. Thank you.

    I have a retired Standardbred gelding I call Black Jack, or BJ for short. He turned 21 last year. He is a sweet guy, and for the past five years he’s been turned out with only mares. Last April my TWH mare, his special girlfriend, jumped the fence into the gelding pasture. BJ was frantic, running the fence and calling her for probably five minutes until we got all the geldings shooed away and her halter on so I could take her back to the mare pasture. BJ checked her out and herded her away from the fences, and everybody went back to grazing. When the time came for them to come in for evening feed, BJ was still out, standing under a tree with three of his favorite mares around him. Nobody was moving. I grabbed his halter and lead, and went out to get him. Up close I saw he had his left rear leg cocked and the girls were all looking right at me. I haltered him but he didn’t want to move. It was a very long, slow trip back to the barn, BJ was really hurting. Gave him some bute for the night and scheduled the vet for the next morning. The vet did an ultrasound on the tendons in his leg…he’d torn the meniscus in his stifle nearly an inch. Vet said stall rest, a Previcox daily, and shockwave therapy every three weeks for four months. BJ was not a happy camper after the first couple of days, and I had to find something to keep him from kicking the stall walls and hurting himself more. I pulled out the catalogs and decided to try the #20E Keep Cool added to his morning supplement bag. In just two days, he’d become Joe Cool. The combination of the Keep Cool and the Previcox was working. No more kicking or protesting. He spent a total of five months in his stall. Vet did another ultrasound in early October – 95% healed, keep him on Keep Cool and Previcox, and he could go back out with his mares. I was terrified the first time I walked him out to the girls. I thought he’d try to run off to them, but he was cool, calm, and collected. He just strolled along with me, no pulling or calling the girls. They were good too, they all stopped eating, stood still and watched us approach. I took his halter off and he walked calmly over to nuzzle his favorite ladies first, then greet the rest. I watched them for a couple hours, and nothing bad happened. He was happy to be back with his ladies. In November it snowed. The vet said to bring him in for the winter – no point risking sucking mud or ice causing a re-injury to his leg. In January we started turning him out alone in our indoor arena. On Jan 4, someone left a door open and he could see the other horses outside. He got himself all worked up and bowed the tendon in his right foreleg. Ice, wrap, more Keep Cool and Previcox, and back to his stall for two months. Now it’s March and he’s once again getting turned out in the indoor with the doors closed so he can’t see the other horses. Still on Keep Cool and Previcox. BJ’s doing well so far. When most of the mud is dried up, he’ll get to go out on a lead line to graze. I will keep him on the Keep Cool for quite a while, until that bow is completely cold. I cannot say enough good things about Keep Cool. It is a major reason my dear old boy is still with me. Without it, he would not have survived the past eleven months. Thank you, Silver Lining Herbs, for your wonderful product, and thank you, Horse Health USA, for your great service and overnight delivery. BJ and I will be forever grateful!

    The next step was to put Prince on Keep Cool for a few months to try to address the distractibility and lack of focus. It calmed him enough so that I could actually teach him some things. I was able to eventually take him off the Keep Cool, the training stuck and we haven”t needed it again.

    Silver Lining Herbs is a product that I 100% believe in and would love to carry. I have specifically seen the most difference in my mare since she has been on Keep Cool. She is so much more focused and it has completely done away with her nervous jitters. Thank You!

    I am a new user of SL products and I am very impressed with the results. My Dash ta Fame gelding was thin and very nervous when I got him a few months ago. On a scale of 1 – 10 for nervousness he scored a 9 if not a 10. He is not scared, just nervous, and was muscles on bones basically and his ribs were apparant, his spine was noticable, and his neck and shoulders were thin. My horse was unhappy, even though he had always had good quality hay or pasture 24 X 7. When I got him I added 8 lbs of Total Equine daily – which is twice as much most horses. After a few months on my feed plan he remained thin and always hungry, never gaining any weight and just nervous with lots of nervous habits like pawing, chewing anything in reach, stamping his feet, and pawing his face. He didn’t know how to walk or trot. Go was lope or run. A month ago, I started giving my horse #20 Keep Cool for relaxation thinking that this would solve his nervousness and help him gain weight. In two weeks he became a 2 for calmness – extremely relaxed – all bad habits are now gone, which is wonderful. After Keep Cool he was still not gaining any weight, so a few weeks ago, I tested his accupressure points and then called SL to ask for product recommendations. SL recommended #37 Kidney and #30 Digestion which I have been giving my horse for the past several weeks added to Keep Cool. Presently my horse is relaxed and gaining weight nicely. I would guess that he has put on at least 50 lbs in muscle with more to go. I am very satisfied with the results of using the SL products and I would recommend them to others. In the case of my horse, his situation was probably a lifelong condition that prevented him from reaching his maximum level of performance between the inability to keep weight on and the nervousness he was a bit of a mess. At this point it seems like I have a totally different horse simply by adding the right SL products to his daily feed ration. I now have big plans for my horse, which will become reality soon. Thanks Silver Lining!

    Our gelding began to forget he was gelded and started “bothering” our mare. We noticed immediate results with Keep Cool and we definitely recommend this! Our vet offered some crazy horrible options like hormones that would affect us too! So thankful for a healthy herbal option that works AND is safe! 🙂

    Keep Cool has really worked well for my mare! She needed her surroundings to be slow, quiet and non intrusive, in other words, move slow at all times to prevent exaggerated reactions and explosions. Only a few days of use and she was very relaxed and handled all the lights, speakers, horses, action and crowds at a National competition. She performed relaxed and focused. I am a believer and will continue to order this product.
