Are at hand any herbal remedies for tourette's syndrome?
Answer: No, however, stress can increase tics, so a stress free (as much as possible) environment is best.
Tourettes is Neurological, or to be more specific, Neurobiological. Think of it this way: A character with TS 's software is fine (aptitude for research, ability to function), but their hardware is wired incorrectly and this cause tics.
Tourettes is lifelong and there is not a cure. However, I do not believe it is a mental syndrome as stated by your other answerer.
It is a spectrum disorder and severe cases can be treated with DBS (Deep Brain Stimulation) similar to Parkinsons. You can't do that near a mental illness!
My son have this disorder. He plays chess, scores high-ranking on IQ tests, is sweet, smart and funny. He have friends, chores and homework just approaching everybody else. I would not trade him for the world.
There are no known or functioning herbal remedies for any mental disorder, none beside enough medical backing to be accepted by any scientific community. Here's this, if you really believe it will work (for yourself, merely saying) then it purely might, w00t to the placebo effect. Yes, but it would require some research, dementias i believe are usually cuased by a weaking nerve or "misguided" as i approaching to call it nerves that hold a protein difficisioncy, so all you would enjoy to do is figure out what that protein is.
