Do acupuncture or herbal medicine help improve concentration?

Maybe it's also due to the weather or health... these days, I find it hard to concentrate on work or studying. It's more difficult to focus for a long time than before. And somehow, my concentration keeps getting scattered. Of course, it could be a mental strength or willpower issue, but I wonder if traditional Korean medicine might help. I also think that improving blood circulation with acupuncture might make my mind clearer. Does anyone have any related experiences or stories to share?
