    Default Does anyone have experience with Grapefruit Seed Extract (GSE)

    Does anyone have experience with Grapefruit Seed Extract (GSE)

    I have read that GSE can kill AFB, has anyone used this as a preventative for AFB? I donít want to use Tylan or Terramycin if I can avoid it. Many have warned me that if I donít do something to prevent AFB I could lose all my hives quickly. See article text http://www.izs.it/vet_italiana/2004/40_2/39.htm

    My mother swears by it for different (human) health reasons, but I've never heard of it used in beekeeping. Curious to see what others have to say.

    VERY interesting. Imagine the possibilites for another "Natural" way to help with a devastating disease like AFB.

    I'm trying to go as "treatment free" as possible.... but AM going to try HOPGUARD this year for mites. Hoping for good results.

    from http://en.wikipedia.org/wiki/Grapefruit_seed_extract
    There are conflicting scientific demonstrations of the efficacy of GSE.[1] Suspicions about the true nature of the active compounds in GSEs arose when synthetic additives were found in commercial products.[2] Suspected counterfeit grapefruit seed extracts were adulterated with synthetic preservatives.[8][9][10] When preservatives were not present in some of the extracts, laboratory tests found the natural extracts had no natural antimicrobial attributes of their own.

    5] Some manufacturers of GSE have stated that their extract has compounds nearly identical to benzethonium chloride, but a 2001 study supervised by chemist G. Takeoka has documented that commercial GSE preparations contain the synthetic compound benzethonium chloride that could not have been made from GSE.[5]
