Reading Time: 6 minutes Grapefruit seeds contain a couple of important chemical compounds (polyphenols) called limonoids and naringenin. Apparently, these compounds act as antimicrobials AND antioxidants, so in addition to killing off bad microbes they protect your body’s tissues against the excessive production of reactive oxygen species which can occur when such pathogens infect the tissues.

While there have not been many scientific studies performed on humans on how grapefruit seed extract works, test tube studies have proven that it works as well as some prescription drugs for conditions such as fungal infections.

Natural health practitioners and many users (including me!) can testify to its efficacy for a number of different and persistent problems. Additionally, grapefruit grows in many areas, and peoples of various cultures throughout the world have used grapefruit seeds to cleanse the body of harmful organisms.
