The father of Grapefruit Extract (GSE) is undoubtedly Dr Jakob Harich

Jakob Harich (1919 – 1996)

Jakob Harich was born in Yugoslavia in 1919 and educated in Germany. However World War II in which he fought as a pilot interrupted his studies in nuclear physics.
After witnessing the horror of war and later receiving an Einstein Laureate for physics he was inspired to devote the rest of his life to improving the human condition. With this in mind he augmented his studies in physics with a full university course in medicine, specializing in gynaecology and immunology.

He emigrated to the United States in 1957, where he continued his studies at Long Island University in New York. He was particularly interested in investigating natural remedies to fight disease-causing microorganisms without causing any harm to humans.

Jakob was a keen gardener and he had noticed that grapefruit seeds in his compost heap did not rot down like other vegetable matter, and so he decided to investigate.
Just after the war when he was in France, his interest in Grapefruit had previously been sparked whilst eating one for breakfast. Fresh fruit was a rare treat in Europe at that time. He quickly and quite accidentally discovered the very bitter taste of the Grapefruit seed and wondered why.

In 1963 he left New York and moved south to the heart of grapefruit country in Florida.

It was here that he started to look more closely at Grapefruit and discovered a substance concealed in the grapefruit seeds that appeared to be more effective, and at the same time less harmful, than any known antibiotic.
The properties of the grapefruit seed extract were discovered by Harich in 1972.
His initial research had uncovered a broad range of efficacy. He found that the extract from the seeds not only inactivated viruses, but also yeasts, other fungi and parasites. Jakob’s GSE – Grapefruit Extract had been born.

Jakob sought support to be able to carry on his research and approached Dr. Steven Otwell and Dr. Wayne Marshall – leading researchers on the effects of microbes on food, based at the University of Florida, Gainesville. Initially, they were very sceptical about his claims that the grapefruit seed extract destroys many microorganisms at the same time as being safe for humans, but soon they became convinced that grapefruit preparations did effectively protect food against bacteria, fungi and parasites. The renown of the science centre, which was their home base prompted other researchers to take interest in the extract.

In the early 1980’s tests conducted by the U.S. Dept. of Agriculture confirmed that GSE was effective in inhibiting viral strains in cattle and pigs (Foot and Mouth Disease, African Swine Fever and, Swine Vesicular Disease), and was approved for the USDA’s Avian Influenza Eradication Program in 1984.
Sadly, USDA’s promise to investigate further uses for GSE in these areas has never materialized.
Since the mid-1980’s, the production team worked closely with Dr. Harich, to perfect the manufacturing process, open new facilities, and pioneer the use of GSE beyond it’s original application.

Finally, by 1990, physicians and holistic health practitioners in the United States started to appreciate the significance of this remarkable product, and understood the implications for their patients, thereby giving Harich’s work the boost into scientific credibility it deserved.

In 1995 Dr. Harich was invited to Europe as a guest of honor of the Louis Pasteur Institute in France, Europe’s leading AIDS research centre. For several years the Institute had been researching the potential of GSE as a prophylactic against the HIV virus as well as against some of the secondary infections associated with AIDS.
By this time his work had also been valued by farmers in Europe who were using a powdered form of Grapefruit Extract (GSE) in fish and poultry feed to prevent two potentially lethal bacteria infections from Salmonella and E. Coli.

Jakob Harich died in May 1996, having gained the satisfaction provided by making his lifelong dreams come true.  GSE is currently used on an increasingly large scale as a harmless product fighting microorganisms and helping people to stay healthy.
It is good to know that during his lifetime he received the recognition he deserved for a life devoted to a revolutionary approach to controlling dangerous microorganisms.
