I believe most supplements and “natural” remedies are a scam. I tried various things…nothing worked. Do you really think I wanted to go to a specialist? I am glad I did, as nothing else worked for my dog.
BTW: ASIT (allergen specific immunotherapy) is the most natural treatment available for environmental allergies. No drugs involved. Of course steroids and antihistamine medications and frequent bathing with Malaseb (sometimes twice a week for my dog, even now) may be necessary from time to time to stop the suffering until the ASIT takes effect.
I hope these articles help:

PS: I would not put anything topically on the dog unless prescribed by a veterinarian that has examined her/him, it could make things worse. We ended up at the emergency vet after I applied witch hazel to a rash.
Do not give over the counter meds to a dog unless approved by a veterinarian that has examined the dog.
