I developed an allergy to dander as an adult. Boooooo! Going completely plant based vegan nearly 3 years ago has greatly improved my allergic reactions and I can now play and be around animals. But I sill get watery eyes from time to time and some hives every now and then. These Bio-allers drops have really helped! I highly recommend them.Try these instead of the over the counter stuff that makes you feel like a walking zombie!
