Citricidal, or grapefruit seed extract (GSE), is the name of a versatile, non-toxic substance made from synthesising some compounds found in the seeds and pulp of grapefruit. Citricidal is an antimicrobial. Researchers say that Citricidal is effective against hundreds of bacterial, viral and fungal strains as well as a number of single and multicelled parasites. You can use it both internally and externally and it also has general household sanitation uses.
The research on GSE in the 1960s at the University of Florida at Gainesville was to create an antiparasitic as an alternative to chemicals to protect fruits and vegetables. Researchers found grapefruit extract not only inhibited the growth of parasites, but also inhibited the growth of bacteria and fungi as well.
Among the most-common ways people use Citricidal is to wash fruits and vegetables and also to wash meats and poultry. While you are at it, you can also sanitise your cutting board or use it to sanitise dishes and cutlery by using it in the dishwasher or by adding it to dishwater or rinse water if you hand wash dishes. In addition, after you finish eating, you can clean your toothbrush by soaking it in Citricidal. However, the household benefits do not stop there. You can also use Citricidal as an all-purpose cleaner for any surface in your house.
Many people use Citricidal externally, but it must be diluted because it can burn the skin. You can use it as a deep-cleaning facial cleanser, but never use it in the eyes. In fact, some people use Citricidal as an ingredient in soap making. But you can also use Citricidal as a skin rinse for minor skin irritations. Some people soak their fingernails in it or apply Citricidal to the cuticle, surface and underside of their fingernails. Some people also use Citricidal on their scalps by putting a few drops of it into a shampoo, just be careful not to get it into your eyes.
Just as you can use Citricidal to clean your toothbrush, you can also use it as a dental rinse or as a gargle. However, you must dilute it if taking it internally. In fact, you can also use Citricidal as an ear or nose rinse, but do not inhale it. You can also use Citricidal to purify water. Among the more controversial uses of Citricidal is as a natural antibiotic. But research shows that Citricidal has an alkalising affect on the body and raises the pH, which is important in fighting bacteria, fungi and viruses because they cannot live in an environment that is alkaline oxygenated.
