Yes, Clary, taking the Arginine and Ornithine is better than nothing at all. When he sees the benefits maybe he'll add the 3 herbs. None of them are expensive.
Clary, why don't you ask him if he remembers hurting his neck at any time during his youth? Ask him to ponder on it and try to remember. Was he knocked unconscious, or suffer a 'brown-out'?
You see, what happens is the upper vertebrae can be subluxated when there is a whiplash or head injury. This causes impingement on the spinal cord which blocks the life-flow of the nerves. Maybe he just needs to have that vertebrae adjusted to open the 'chi' blockages. I've seen miracles happen that way. The challenge is finding a talented Doctor. Do you happen to live near Lexington KY?
