Candidly, if she isn't willing to help herself, there is probably little you can do. That is, if course, the reason I asked the question. With that in mind, she certainly has options....
It certainly sounds like she is eligible for a restraining order (RO). An RO is based on acts of violence or threats of violence. To obtain an RO, she would need to go to the local courthouse and request a petition for an RO. She would fill out the petition for review by a judge. If the judge felt that she was reasonably in fear for her safety, the RO would be issued. In that event, the husband would be prohibited from having any contact with your friend.
If there is anything recent, she could potentially have him arrested. If there have been any recent incidents of battery (an unlawful touching) or assault (placing her in fear for her safety), she could call the local police department and provide the details of the events. If the officers felt the had probable cause, he could be arrested and criminally prosecuted.
She could file for divorce. This is, of course, the most extreme remedy, but it certainly seems worth exploring. If she is indeed being abused, she should certainly consider separating herself from her abuser.
If she is interested in pursuing any of these matters, first, you should begin with your state bar association. The Ohio State Bar has a website, it is located at www.ohiobar.org.
I do not know your county of residence but your county bar association likely has a similar site that will be more specific to your location.
Additionally, Martindale Hubbell is a national organization that rates attorneys across the country. Their website is located at http://www.martindale.com/.
Another nationwide website is located at http://www.avvo.com/. This site lists attorneys by geographic location and area of practice.
Additionally, there is quite likely a legal aid society in your area. A quick internet search and/or phone book search should locate the society closest to you.
