My horse has suffered from allergies for the past 3 years now and I am going to start trying some natural supplements to see if anything helps. He has been on allergy shots for two years now and they have gotten rid of the full body hives he used to have but he is still getting swelling in his glands and over his cheek bones. Has anyone had progress with natural allergy remedies? I am trying to find products that are USEF legal that might help my guy.
He is already on MSM.
TIA!
