Skullcap is a nervine. I recommended it to a friend when her son was diagnosed with Bells Pulsy...a condition that came on suddenly (which disfigured his face horribly ...one whole side drooped) At the time he wanted to go to Walter State Community College and because of this ailment he was given a special scholarship. After using skullcap for several days he was normal again! He still retained his scholarship, though , which was great. The doctors had tried a couple things I guess, but nothing had helped at all. It is good for neuralgia. I read once that it helps nerves re-connect properly.
I made a skullcap oil for my friend with PD, which I use on her spine/back during massage treatments. It seems to help her.
