This was such a concern for many governing bodies and regulatory agencies that methods for screening plant extract products for synthetic additives were developed, this, I believe, was in part due to the interactions many of these synthetic disinfectants can have with pharmaceutical products and treatments (12) (16). Although subsequent testing by various extraction companies have shown that when extracted properly, stored properly and sourced organically, there are many inherent qualities to be found (3)(5)(9).

Claiming that the inherent properties of G.S.E were due to containing the synthetic extracts (8). A number of products have been tested in the U.S and have been found to contain these substances, in one study I’ve found, the researchers even made their own batch of weakened extract and found that it had no properties at all. The Controversy surrounding G.S.E is due to some suppliers adding synthetic disinfectants (benzalkonium and benzethonium chlorides) (2) to their products in order to use a minimal amount (if any!)of actual seed and pulp extract. ‘Why?’ he wondered, then, after much research and experimentation, he managed to create a stable extract to work with.

The Discovery of G.S.E in the early 80’s was almost completely by mistake, Dr Harich, an American immunologist who was also an avid Gardener noticed in passing one day that the Grapefruit seeds on his compost pile degraded considerably slower than everything around them. over this article I’ll be looking at the controversy surrounding it as well as discussing how G.S.E works and the potential applications for our Canine Friends. Grapefruit seed extract or G.S.E is a relatively new substance (Less than 40 years old (1)), but has been the subject of much controversy across the scientific and medical industries.
