Grapefruit seed extract

Grapefruit Seed Extract (GSE), also known as citrus seed extract, is a liquid derived from the seeds, pulp, and white membranes of grapefruit. It is used in various forms, including as a supplement and in personal care products, due to its purported antimicrobial properties.

History

The use of grapefruit seed extract dates back to the 1970s when an American immunologist, Dr. Jacob Harich, discovered its potential benefits. He noticed that grapefruit seeds, which were discarded in his garden, did not decompose like other organic matter, leading him to investigate their properties.

Production

The production of grapefruit seed extract involves grinding the grapefruit seed and pulp into a fine powder. The powder is then dissolved in water and distilled to remove the fiber and pith. The resulting liquid is rich in plant chemicals, including flavonoids, Vitamin C, tocopherols, citric acid, limonoids, sterols, and trace minerals.

Uses

Grapefruit seed extract is used in a variety of applications due to its antimicrobial properties. It is often found in health supplements, personal care products like toothpaste and shampoo, and home cleaning products. It is also used in agriculture as a non-toxic alternative to synthetic pesticides and fertilizers.

Health Benefits

While research is ongoing, some studies suggest that grapefruit seed extract may have several health benefits. These include potential antimicrobial effects, antioxidant properties, and possible benefits for skin health. However, more research is needed to confirm these effects and understand their mechanisms.

Safety and Side Effects

Grapefruit seed extract is generally considered safe for topical and oral use. However, it can interact with certain medications, particularly those metabolized by the liver. Side effects are rare but can include skin irritation and stomach upset.
