Elderberry coloring oil

  1. Jul 14, 2007 #1
    I found that the leaves of the elderberry tree (Sambucus nigra) can be used to add a green coloring to oils and fats, among other things, is this claim true?

    Also what compound in the edible berries makes it a good pH indicator (red=acid blue=base)? The leaves make good mosquito repellent (tried it, it works, and good).
