I have been putting this off for a year. I hate experiments. I have Alkanet Root and infused it for a couple of days with Sunflower oil. It was very dark in color, the oil was. I used 1 oz to 4 oz of oil. Here is how it worked. Should I have use more. I used one oz to 3 lb loft. At first it was blue, then after 24 hrs it looks more purple, I used Lavender eo.
