You can make a decoction out of ginger and use a cotton ball to rub it into the infection site.  Another way this can be used is to make a tea.  There's even ginger candy for those who don't like capsules or teas!  The candies are made from rhizomes and sugars  This doesn't affect the brain so much, mostly the stomach.  Did you know that this herb has a class B recommendation for use of nausea and vomiting in pregnant patients?  That's super cool and I wish more herbals have this recommendation!
