We've had success using CBD Oil to treat our Autistic son. We started administering the oil to our son a week before his 3rd birthday. Within a few days we saw a massive change in him. He was calmer, had less meltdowns, could tolerate food better, slept better at night and was able to follow instructions - something he had so much trouble doing in the past. After a month of administering the oil to him, we ran out and had to wait about a week for the new batch of oil to arrive. That is when we could really see the difference the oil made to his overall health. During that week, all of his ASD symptoms were back. He displayed erratic behaviour, had several meltdowns, didn't sleep well, had food intolerance, etc. As soon as the oil arrived we administered it again and after a few days he was back to a normal little boy, playing, laughing and interacting with us. We have used the oil in conjunction with a healthy diet and other supplements to get the best results.
