Grapefruit Seed Extract
GSE is an extremely potent and effective broad-spectrum bactericide, fungicide, antiviral and antiparasitic compound., is environmentally safe with a low toxicity to man and animals. It is becoming the disinfectant and sanitizing agent of choice for many hospitals and clinics throughout the United States. It is reported that, ten to fifteen drops per gallon is effective in killing Staph, Strep, Aspergillus, Salmonella and many other pathogenic organisms which are present in hospital carpets. The same 10 to 15 drops per gallon of water is effective when applied from a spray bottle in the loft.
GSE does not produce the negative side-effects associated with antibiotic use. Intestinal flora remain intact with the use of GSE. Chemical measures(like chlorox, and other disinfectants) add stress to the constitution, in some cases resulting in increased exposure to re-infection.
Test also indicate it is effective against many repertory and other infections. 9 drops per gallon of water has been given once a week to my birds as a preventative measure.
