Just because something is herbal, it does not mean it won't increase risk of bleeding. Fish oil and garlic are common ones. Ginseng is another, and there are two types of ginseng in the supplement noted in the above post. It all depends on the dose and your sensitivity. If there is a large enough dose to actually have a pharmeceutical effect, it probably can also cause side effects.
Just be sure to look up the ingredients of these things.
