When I received this commiphora resin I wasn't sure what to do with it. It was new to me and I needed to go through all the steps of evaluating properly. Of course it needed to be tinctured before I could do that. I measured the resin & alcohol and added them to a jar. I tucked it away in a cabinet and completely forgot about it. Months passed before I remembered it was there. It had been tincturing for over a year when I thought to use it in my Nymph (A Midsummer Night's Dream Scent Event) perfume. I used a rather large percentage in my formulation and I must say it adds a rich warmth and mild sweetness to my blend. I like what it adds to my perfume, so much so that I plan to buy more. Anyone interested in purchasing this commiphora resin, along with a couple others can do so from the African Aromatics site. These resins are shipped from South Africa by natural perfumer Sophia Du Toit.
