What is Citricidal®? Citricidal® is synthesized from the polyphenolic compounds found in grapefruit seed and pulp of certified, organically-grown grapefruit.

Originally developed by German researcher Jacob Harich (1919-1996) as an anti-parasitic agent, grapefruit seed extract (GSE) was further researched by University of Florida at Gainesville as an effective means of protecting fruits and vegetables from mold damage, who found that GSE could also inhibit growth of bacteria, mold and fungi.

When used at appropriate doses, no other known antibiotic exhibits such safety and versatility - GSE is highly active against many disease-causing pathogens, including protozoa, bacteria, yeast and some viruses. GSE can be administered for up to several months, which may be necessary for some stubborn, chronic infections.GSEis also being used to benefit pets and animals of all sizes. Its uses are only limited by ones imagination.
