Is the liquid dark amber or gold color?

It’s a lighter amber and a little sweeter, because of the licorice. It’s good to have on hand, but if you’re a purist I would suggest another brand. It’s too sweet for me.

"Plus" what? Any other herbs such as Echinacea or Goldenseal?

Here are the following ingredients in the Propolis; A proprietary blend of Forsythia (F. suspensa) (Fruit), Licorice (Glycyrrhiza glabra) (Root), Slippery Elm (Ulmus tulva) (Bark), Bee Propolis, Whole Cloves (Syzguim aromaticum), Goldenseal (Hydrastis canadensis) (root), Myrrh (Commiphora myrrha) (Gum), Echinacea (Echinacea purpurea) (Root) Extracts

What are the other ingredients ?

Other ingredients are: Distilled Water, Vegetable Glycerin, Grain Alcohol, and Natural Cherry Flavor (I copied them from the bottle).

what is the concentration?

Amanda, I read the label twice and saw no information about the concentration. You might be able to get your question answered on their website. Now dot com I think.
