It works very well on a variety of symptoms/ailments. I gave it to my son for anxiety and it was helpful, I also tried it myself when anxious and noticed a calming/relaxing effect. My mother has taken it for chronic pain and it has helped her. I know numerous people who use it, all with benefit. It is also supposed to help with epilepsy and a whole plethora of other things.

Edit: There are various strengths available, the stronger it is the less you need to take. I have only tried the one without THC since THC is the psychoactive 'high' element and not as likely to help reduce stress.
