My horse hasn't felt this good in years! One of my horses has moon blindness and sinus allergies. The moonblindness gets worse when the sinuses flare up, so I was looking for something to help with sinus and eye issues. When my homeopathic vet retired I was forced to find new meds. After days of researching ingredients, processes and more, I finally found this (wasn't easy to find). I am using it in conjunction with a targeted eye relief supplement (also not easy to find) from another company and I've waited about 8 weeks to ensure consistent results. The results have truly been amazing! The swelling above the eye is down, the eye is clearer (as clear as it can be), she isn't suffering from what I equate to a migraine headache, and is so much happier. Obviously I can't say which med is doing what exactly, but I know for a fact that her allergy and sinus flareups have been almost gone, and with the up and down winter weather lately, I 100% would have seen sinus issues in the past. I am so absolutely thrilled! I cannot say how glad I am that I found this product and feel 100% safe giving it to my horse.
