Taking Dr. Shulze's herbs during first trimester of pregnancy

Hi there,
I am 8 weeks pregnant and I would like to know if it is safe to use Dr. Shulze's (or any herbal remedy for that matter) Cold & Flu tonic, Echinacea Plus tincture, and Intestinal formula 1 pills.

(The main herbs in those tinctures are: Echinacea angustifolia, purpuria, garlic, Cayenne, Senna Leaves, boneset flower, quaking aspen, pleurisy root, ma huang, yerba santa leaf, elecampane root, osha root, sage, elder flower, yarrow flower, wild cherry, horehound, kola nut, goldenseal rhizome, and lobelia )

I have a flu with low fever (99.1) for several days now and would like to treat it naturally.
Thanks in advance,
