Not natural, not safe: Grapefruit Seed Extract
https://www.sciencebasedmedicine.org/not-natural-not-safe-grapefruit-seed-extract/"...
GSE is claimed to be produced from the seeds of the grapefruit (Citrus x paradisi). The production method isn’t clearly described but different manufacturers say they grind the seeds and pulp in water, and then process this chemically to yield an extract. The methodology of production doesn’t appear standardized, nor is it disclosed in sufficient details to given consumers any assurance that the product is consistent (in content) or safe to consume.
...
There is a serious problem with commercially available GSE products sold on the market. There’s an over 20-year history of adulteration of GSE products with synthetic antibacterial disinfectants and cleansers. The first report appeared in the 1990s when testing of a commercially-available GSE product found benzalkonium chloride and triclosan, which were not found in an extract of the seeds themselves. A 1999 study tested six products. Five were effective inhibitors of bacteria and fungus in test tubes. In all five products, the synthetic preservative benzethonium chloride was detected. Three extracts also contained triclosan and methylparaben. The one GSE product with no additives also had no efficacy. The investigators also tested their own seed extract, as well as pulp. No antibacterial or antifungal properties were noted. In their own words:
...
GSE products have the potential to cause significant drug interactions. One case report notes that a GSE product significantly increased the levels of warfarin (Coumadin), which means a significantly increased risk of bleeding for patients taking the drug. Upon further examination of the product it was determined that the active ingredient was actually benzethonium chloride. Benzethonium is an antiseptic that is for surface disinfection and is also in consumer products like mouthwash.
...
There is no evidence suggesting that actual grapefruit seed extract has any meaningful antibacterial, antifungal, or antiviral effects. Repeated testing over the past 20 years has demonstrated that any GSE efficacy is due to product adulteration with one or more synthetic chemical disinfectants. Adulterated or not, there is no reason to take GSE at all. The fact that it continues to be widely sold is testament to the ineffectiveness of regulations that should put consumer safety ahead of a manufacturer’s right to sell a dodgy product."
