There is "take care of", "care about" and "take care about", which all mean different things. to take care of = to look after or to provide care for For example: She took care of her mother when she became sick to care about = to feel concern or interest for For example: I hope that you will stop smoking because I really care about you. to take care about = to be careful about For example: If you want to stay healthy, you better take care about what you eat.

To take care is to fix a problem or help someone. And example for fixing a problem would be: I need to take care of that leaky sink. Here's an example to help someone: I need to take care of my grandmother because she is sick. As for Take care about... I don't know what you mean. I've never heard someone say "take care about" before. Maybe "Take care about holding that vase"? That means to have care and take care of the vase, so you don't drop it or break it. But then again, no one says that.

As Viviane said, take care about means to be careful about something. One thing to keep in mind though, this is more of a British way of speaking. An American would understand it, only it'd sound unusual to them (us).
