The wikipedia article cited states that no studies have proven its ability to kill pathogens.
Simply google: Grapefruit seed extract tea tree staph.
There are several science articles stating the same thing.
G.S.E. combined with tea tree kills one strain of MRSA.
G.S.E. combined with Geranium oil kills the other strain of MRSA.
So dont listen to the wiki article author tell you that there is "no scientific evidence".

I put grapefruit seed extract dilluted with warm damp cotton pad.
Today I used 6 drops GSE with spoonful coconut oil and a capsule of activated charcoal on a flat cotton pad and taped it to my neck on what I thought was a spider bite, but the level of itchiness has me mega concerned and additional bumps around it. I'm catching it VERY early, so I will continue this until its gone. I recommend this combo for your grandma's knee. Do it everyday until its gone. Change it often
