While I agree with the soaking in alcohol first before adding herbs to oil, I don't believe that alone will change the colour of the salve. I follow Kami's technique and it is the blending of the herbs that pulls out the chlorophyll from the plants. The final result changes the colour of salves and oils greatly. This can be a good or bag thing. For instance, when I use Kami's technique to make my calendula infused jojoba oil, I get a very orange face oil, that is not attractive in the least. I have also given my very green salve to someone, who didn't like the green because it stained clothes. So, while I believe Kami's technique results in a superior product, it is not for all.
