Taking Herbs and Supplements

My first question is:
Why can ginseng only be taken for one month and then ceased? How long after can you start taking again and what are the side effects, if any? Can this affect surgery if needed?
Second question is:
Can you explain what exactly CoQ enzyme is? Can this be taken daily? Side effects? How does this help the body?
Third question is:
Can several herbs, vitamins, minerals etc. be taken daily? To expand, I am specifically talking about the following: I take these daily, to aid me instead of taking medicines etc., but I am quite concerned as to whether all the below listed can be taken together, with the largest meal of the day (Dinner) at around 6:00 p.m. every night. Please, elaborate or direct me to someone who can help me with this very important issue.
My daily intake: Pycnogenol; CoQ enzyme; was taking ginseng; a multivitamin; selenium; cat's claw; grape seed; was taking feverfew; echinacea; garlic.
Fourth question is:
What do you know about pycnogenol? Elaborate, if you can? Also, is it safe?
