Since the actual amount of these unlisted chemicals can vary greatly and they are prohibited for internal usage, several natural health professionals advise against ingesting GSE health products.
They conclude that any antibacterial activity in grapefruit extract products is likely attributable to these synthetic additions and not to the grapefruit extract itself.American Botanical Council researchers from Austin, Texas reported in a 2012 investigation that many grapefruit seed extract products on the market today include synthetic compounds that are not stated on their labels.

Mechanism of action and in vitro toxicity – PubMed Who should not consume extract of grapefruit seeds?Ĭan extract of grapefruit seeds be harmful? Grapefruit seed extract used topically can occasionally cause skin irritation. Even at lower doses, it was clear that GSE breaks the bacterial membrane and releases the cytoplasmic contents after 15 minutes of contact.: The efficiency of processed grapefruit-seed extract as an antibacterial agent: II.
With the use of scanning transmission electron microscopy (STEM), the antibacterial mechanism of GSE was uncovered.
Initial findings indicate that GSE has antibacterial activities against a broad spectrum of gram-negative and gram-positive pathogens at safe dilutions. However, test findings revealed that at a dilution of 1:512, GSE remained bactericidal but was fully harmless. These studies demonstrated that GSE remained both toxic and bactericidal at doses ranging from 1:1 to 1:128. Gram-negative and gram-positive isolates were added to progressive dilutions of GSE (twofold concentrations ranging from 1:1 to 1:512) to assess bacterial activity.Īt the same dilutions, in vitro tests with human skin fibroblast cells were also conducted to investigate toxicity.This study examined GSE for antibacterial activity at varied time intervals and concentration levels, as well as tissue toxicity at varying concentrations, in an effort to establish if a microbicidal and nontoxic concentration existed, and if so, for how long.Mechanism of action and in vitro toxicity – PubMed Objectives: Recent testimonials indicate that grapefruit-seed extract, also known as GSE (Citricidal), is effective against over 800 bacterial and virus strains, 100 fungal strains, and a huge number of single- and multicellular parasites. The antibacterial efficacy of processed grapefruit-seed extract: II. Commercially available GSE is made from the seed, pulp, glycerin, and synthetic preservatives all blended together. GSE is prepared by grinding the grapefruit seed and juiceless pulp, then mixing with glycerin.
