Pet-Med Allergy Spray brings together Antimonium crudum, Apis, Galphimia glauca, Urtica urens, Viola tricolor, Tradescantia, a common allergen mix, histamine, and cortisone. In homeopathic use, these ingredients are commonly chosen to support pets with allergy-type skin reactions, itching, swelling, and seasonal irritation.
The extra value in the blend is that it can combine remedies linked with itchy skin, hives-like reactions, and over-response to common triggers.
Galphimia and Urtica are both commonly discussed in allergy support, which helps explain their inclusion here.
