Grapefruit Seed Extract Description
The main active components are a group of quaternary ammonium chlorides, including benzethonium chloride that make up about 8-17% of the grapefruit seed extract. Benzethonium chloride is a well-known synthetic antiseptic agent which occurs naturally from the original grapefruit flavonoids by an ammoniation process.
When introduced to the extract, researchers at the University of Florida at Gainesville were impressed by its ability to inhibit the growth of bacteria, mold, and fungi in vegetables and fruits.
Grapefruit seed extract (GSE) has been found to be a broad-spectrum natural antibiotic, capable of killing a wide variety of pathogens. It is highly active against protozoa, bacteria, yeast and some viruses. GSE can be administered for up to several months, which may be required to eliminate certain stubborn infections.
Grapefruit Seed Extract is becoming known as one the best topical and internal antiseptics available and is both bacteriostatic and bacteriocidal at various concentrations.
Suggested Use
External Use:
Grapefruit seed extract is reputed to have been effective in treating hundreds of different organisms including: Shigella, Staphylococcus, Pseudomonas aeruginosa, Giardia lamblia, Diplococcus pneumoniae, Haemophilus influenzae, Mycobacterium species, Campylobacter, Candida albicans, Escherichia coli, Streptococcus, Salmonella, Klebsiella, Proteus, Cholera, Chlamydia trachomatis, Trichomonas vaginalis, Legionella pneumoniae, Helicobacter pylori, Herpes simplex 1, Influenza A2, and measles virus. GSE has been shown to kill both gram-negative and gram-positive strains of bacteria.
Warnings:
If used over a prolonged period, it would be advisable to supplement with a probiotic to prevent bowel disbiosis. If you develop an allergy or sensitivity to this or any other supplement, stop either internal or external use.

Suggested Use
External Use:
- GSE can be used externally as a disinfectant for both intact skin and to prevent infection in wounds.
- A Brazilian study found it to be 100% effective (at 100ppm) for skin disinfection when used as a pre-surgical prep compared to an effectiveness rate of 72% for alcohol and 98% for commercially available surgical soap.
- GSE can also be used internally to treat chronic infections. It is often recommended at a rate of 3 times per day. Dosage should not exceed a total of 1500mg per day.
- Spray or use an eye-dropper to get several diluted drops into each nostril, and then swing the head quickly forward and down (so head is upside-down), forcing the liquid up into the nasal passages. Use up to six times per day.
- GSE is added to one pint of water. Use twice a day as a douche for up to a week, in the treatment of yeast infections.
