    Absolutely love this herbal wormer! I’m huge into herbal medicine but am always skeptical on other brands out there until I came across SLH! I used this wormer on two horses I got this year, a two year old and a rescue mare in her late teens who was in rough shape upon arrival. This wormer worked so well for the both of them. Not only did it take care of any potential worms/parasites but I also noticed it helped with their coats as well. I will definitely continue to keep using this wormer! Love that it comes in a resealable bag and with a scoop too! The wormer smells garlicy, but my horses don’t even seem to notice!

    I am so impressed with this product! In the past, using only chemical dewormers, my horse’s egg count from a fecal test would be anywhere from 500-800 eggs/gram. After using Silver Linings Herbal Wormer for a few months last year, his egg count went down to 300 (tested at the same time of year). This year, after using the product consistently for a whole year (and no chemical dewormers), his egg count went down to 32!

    I have been using #13 herbal wormer for a year and a half now on my personal and training horses. I originally was not sure how well it would work but I was tired of using paste dewormers and it upsetting my horses digestive system every time. After about 4 months I asked my husband, ” is it just me or do all the horses look like hippos”. I had not changed their feed quantities and they all put on extra weight and looked so thick in a good way. They also did not have the digestive issues that always followed paste deworming. Needles to say, they have all been put on less feed, and I am forever sold on using herbal wormer #13. Thank you silver Lining Herbs for making great products I can trust to work.

    I own 5 horses and it is impossible to work them all with paste and know they are getting as much as they need plus having to rotate wormers is expensive and exhausting. Silver lining herbs has made working horses so easy!!! My horses love this stuff. It is so easy to feed it right in with their grain. It is an amazing product and covered all areas horses need to be work free.

    I have been using SL’s herbal wormer for the past ten years. My horses do well with this and I get good results when I do fecal parasite counts. I just want to tell you how delighted I was when I opened my most recent order to find the complimentary magnetic 2020 de-worming with the moon schedule! Silver Lining ROCKS!

    While I found it great this product works so well I feel I must add that if your horses have worms then so does the owner. Medical doctors will never mention doing a parasite cleanse. If your going to treat the animals you love you should also treat yourself. Find a Holistic doctor and you will find they use these exact same herbs that you just gave your horse.

    This is a fantastic product, no more chemical deworming paste. My horses are staying parasite-free.

    After only a month of using the Digestive Support and the Herbal Wormer, my mare stopped rubbing her tail as frequently, tested 100% negative for eggs in her manure, began gaining weight and her coat began to become shinier.

    I am writing to say Thank You for creating such wonderful products. After my 21 year old gelding was diagnosed with EPM, I was looking for a way to keep him comfortable and healthy. Unable to afford the pharmaceutical treatments, I began looking for other means. I had heard about your products throught a barrel racing website and decided to give them a try. I purchased the suggested EPM products (#11, 13, 24, 30). After only 7 days, my gelding went from leaning on the fence, not wanting to move, to being back out in the pasture wandering around and eating. While he still has his “bad” days, I am amazed at the progress he has shown in such a short time. He went from needing to be put down to being comfortable and happy agian. Thank you again for your products.

    I have written to you several times recently for help and advice for my appaloosa mare, Dixie, for her fight against EPM – I would like you to know that her improvement over the last week to 10 days has been nothing short of a miracle!! Her in-coordination is barley perceptible, even at a trot. Her mood and appetite have greatly improved – She is my old Dixie again, bright, friendly, and quite bossy, demanding treats and attention. I can only attribute the changes to your wonderful products, CNS Support, Worm Foe, Immune Support and LCR! Thank you for your advice and many, many thanks for your wonderful products!!

    While dealing with the consequences of EPM (2004) on my gelding, Traveller, a massage therapist suggested I check out Silver Lining products. I called and talked to Mr. Young and found his advise to be extremely helpful. Before giving Traveller #11 CNS Support, my therapist was telling me she felt heat in his poll area. One week after starting him on #11, she felt no heat. He also had many strange episodes similar to colic or a seizure over a 5 month period in 2005-2006. Based on a blood test, my vet suggested he had an ulcer. I put him on the #29 LCR, and he has not had those episodes since (2 years later). I also used the #24 Immune Support and #13 Worm Foe. Today, at age 23 he is looking better than ever, is able to be ridden lightly, and is still my “Old Reliable.” I am currently giving him #11 and #18.

    Thanks for the info on the shipping. That’s what I like about your company, you’re prompt. I have been using the training formula and the parasite foe for about 4 months now, and I really see a big difference in my horse. Anytime I can get something natural into my horses’ system, the better I like it! Thanks for putting out a great product!

  15. Sheila Morlas Rocklin

    I just wanted to tell you how pleased I am with your #13 Worm Foe. I have had my mare Kalyssa on it for about 5 years now and she has been on different pastures at boarding facilities with other horses. I just got a fecal check done and the results were “1 egg per Gram” !!! That is an extremely low, low count! I have not paste wormed her in about 6 years, and by the looks of it I will never chemically worm her again. Thank you for such a wonderful product!

    Silver lining herbs wormer for horses really works. I was totally a doubter……but it really works. I have our horses on a typical worming routine ….and yet found worms after only the first dose of these herbs. I was taken surprised and so glad i took a chance on this wonderful product.

  17. Jessica Lopez

    A few months ago I bought your wormer formula for my horse. She was having serious colic problems that she had never had before, and was abnormally sensitive about her stomach. Guess what: After the first 5 days of application, her stomach felt better and the bloated-apearence of her sides began to lessen. After the first full 10 days, she was much happier and easier to work with. I have been using the product since, and her health and attitude have improved. Thank you so much for listening to your gutt and searching for healthy alternatives for equine wholeness. My horse and I are truly grateful! Keep up the good work.

    The herbal wormer has really helped with the managment of our mare’s weight and has actually improved her mood! I guess that means she is more comfortable. Keep up the great work and products and thank you, thank you, thank you!

    My 29-year-old horse, Topper, has been a part of my life since we had his mother bred. Two years ago, he was diagnosed with E.P.M. (equine protozoal myeloencephalitis). This virus attacks the brain and the central nervous system, which was manifesting itself in Topper’s losing control of his hind quarters. Traditional medicine could only offer me a drug that had no guarantee and chances of side effects, which was disconcerting to me, especially considering his age. I did some research and was so blessed to find Silver Lining Herbs. After a couple weeks of giving Silver Lining’s herbal supplement protocol for E.P.M., Topper improved drastically. Even my vet was amazed telling me “whatever I was doing; I needed to keep it up!!” Two years later, the herbs continue to make a difference. There is a direct correlation between the supplements and his improvement. If the recommended dosage is slightly decreased or a day is missed, his previous symptoms resurface. Silver Lining Herbs are a necessity in maintaining Topper’s health.

    Today I received the results of the fecal egg count from the veterinarian and…drum roll, please, it is ZERO for the third time in a row! I give Thoroughbred ex-racehorse “Splendid High” aka “Mel” the herbal wormer every month for 10 days as directed, culminating on the full moon. ( I get a kick out of those directions!) I have the vet send in the fecal egg count every Fall and Spring around exam time to document and be sure it is working. I can say for sure that Splendid High awards it his highest prize as he nickers for it (as I mix it in his oats and pellets–both organically grown, as our way of staying as free of toxins as possible). No nasty paste and no icky taste *and* it works…he gives it his splendid endorsement, indeed! Thank you so much Silver Lining Herbs for your excellent and effective product! A solid 24 karat gold endorsement from a 24 carrot horse with a heart of gold….

    Our Arabian mare had a really high fecal count (over 4,000) and I was told that at that high levels you don’t want to “play around with herbal supplements”. I was even told by the vet that he had never seen any herbal dewormers work at so high counts. As I know how toxic the pharmaceutical dewormers can be we still went to ahead and gave our mare nr 13, and sure enough she was worm free after only one month! It’s happened twice, so I’m convinced this is really effective. I also like the fact that he doesn’t have any diatomaceous earth in it.

    I tried various other natural worming methods and #13 is the first one that actually worked! I also suggest using the ‘start 3 days before the full moon’ to begin the 10 day regimen of this Herbal Wormer as going this route is what finally put my mare below the 200 epg fecal result. HIGHLY recommended.
