Twitching and Ticks

I was talking to my sister the other day and she was telling me how her son is having ticks and twitching of the shoulders(I think this is what a tick is?)as well as obsessive compulsive behaviors.

She's very aware that we are into alternative therapies and is also intereseted in it herself, though not as much as me. I recommended some books to her and told her how well we are doing with our healthy lifestyle(she eats regular grocery store food and uses chemical products). I told her how my son and I were healed from our OCD.

I was wondering if anyone knew of anything specific that could help or has helped them with ticks? Diet is going to play the biggest factor in getting well, of course, but our there any other therapies you know of that could help with ticks.

Thanks!
