Anger Management Herbal Remedies?

I have a brother who I think has some anger management issues. He is such a kind and lovely person but if he is pushed to his limits, it is difficult for him to control his anger. He sometimes end up saying things that hurt the other person verbally. I am just wondering whether there are herbal medicines that someone can use to calm him down and give him more control over his reactions.

I recommend that you look into Bach Flower remedies. They are appropriate for mood-related issues.
There are many excellent anger-management courses. Meditation courses may be helpful. Vipassina, or "mindfulness" meditation, helps a person to stay in the moment, helping to recognize when anger is approaching. It is very easy to do and does not consists of any religion or dogma.
