Grapefruit Seed Extract

Grapefruit seed extract, also referred to as citrus seed extract, is prepared from the seeds, pulp, and membranes of the grapefruit (by-products of the juice). It was originally developed by a nuclear physicist, Dr. Jacob Harich, in 1972. Since then, it has been used for human and animal health, skin care, and cleaning purposes. It is claimed to be non-toxic, quickly bio-degradable, and environmentally safe.

Grapefruit Seed Extract Benefits

Grapefruit seed extract has been shown to be effective against bacteria (including Escherichia coli, Staphyloccus aureus, Salmonella typhi, Streptococcus pyogenes, and Klebsiella pneumoniae), viruses, fungi, and parasites. However, according to this research[1], only commercial preparations that contain synthetic preservatives (like benzalkonium chloride - a common synthetic antimicrobial used in cleaning products) were shown to have this benefit. No antimicrobial activity was detected with all-natural products.

Unlike antibiotics, grapefruit seed extract, if used correctly, does not harm “good” bacteria or become resistant to microorganisms.

Grapefruit seed extract benefits many conditions, including:

  • colds and flu
  • sore throat
