A line of natural Homeopathic medicine manufactured by NatraBio (http://www.natrabio.com/). The line is composed of several different types of medicines in pill, liquid, and spray forms. It includes treatments for pet allergies, pollen allergies, dust allergies, mold allergies, and others.
I am currently using their Pollen/Hayfever Relief medicine to treat my seasonal allergies, and it is working very well. I would recommend this medicine in particular, and Homeopathic medicine in general, to anyone who has environmental allergies.
