I am a firm believer in propolis. Started taking it daily in May last year. My allergies always freak out in Mid October. They did not this past year. I am sure that propolis played a major role. I also am eating alot more honey than ever before so maybe it was a combination of the two. I tried to get my wife to take it with me but she did not like the look of it. Well, after she was all snotted up this past fall and I was not, she became a convert.
