Does St. John S Wort Cause Any Side Effects?

My 16 year old s_grandson had wisdom teeth removed and has been on hydrocodone. It has been a week and now he has developed cold sores so I gave him st Johns wort 1.8 g one time for the cold sores. I am so afraid I have made a mistake in doing so. How likely is it that there could be a bad reaction and what bad reaction could he have?
