Hi Kerrieann,
I took SJW for a time a few years ago to help me when I was feeling particularly low, and found it really very good. It just made me a bit more cheerful. The only side effect I 'suffered' was I got a suntan much more easily! As I have pretty low blood pressure anyway I have no idea if it increased it. I felt fine, physically. Not very helpful, I'm sorry. I guess 2 days is a short time, I don't know if it would have any effect so quickly - it is said you need to take it for a month or so before you really see an improvement in mood. So the raised blood pressure could be something else? Can you consult a qualified herbalist?
