I was on herbs for 10 years for crohns disease. It's difficult to say if they worked or if my body got better with time and diet and fitness.
However with my TBI I am entrusting a friend who has done her masters in homeopathy.

She is focusing on the injury and keeping my nervous system calm.

The trouble is a side effect of a TBI as you will know is a lack of emotion. So once again who knows if it's the homeopathy or the physical brain change that will result in me being a calmer person.
