A 18-year-old female asked:

I fell down the other day and grazed my knee, washed it straight away. a scab is forming and part of it is yellowy-green. could it be infected?

Skin infection: It could be infected. If you have swelling, tenderness and heat in the area this is an indication of a deeper infection. One of my favorite treatments for superficail wounds is acetic acid, which is white vinegar. 1/3 cup to a pint of water. soak for a few minutes and apply antibiotic ointment if you are not allergic to it.
