If you specifically want CS teas, try the Apricot Honeybush. It doesn't have any of those things in it. Last time I was pregnant, I read the labels on all the teas voraciously, and had a list of "not recommended" herbs. This time I'm more with the attitude that most of those so-called risks aren't. If you look around, some people recommend avoiding ginger during pregnancy, yet I live on the stuff to combat nausea (and every doctor/midwife I know has recommended it for that purpose).
From my herbal encyclopedia:
Chicory - is considered... to be a mild tonic, diuretic and laxative.
If you're eating raddicchio or endive or Treviso, those are all chicory.
Chicory root has a very high level of folic acid, and the leaves have a high level of potassium.
Hawthorn - Scientists have discovered that hawthorn dilated blood vessels, allowing blood to flow more freely and thus lowering blood pressure. In addition, it acts directly on the heart muscle to help a damaged heart work more efficiently. Hawthorn works slowly and appears to be toxic only in large doses...
In the 3 herbal books I just consulted, none of them said anything about avoiding either of these herbs during pregnancy.
