Apothecary’s Garden is in Canada and has a number of interesting and “off the beaten track” incense materials, as well as tinctures at his Etsy store. The owner does much of the materials collecting all over the world , which you can read about in his blog.
I have tried the Frankincense Rivae, Papyrifera and Neglecta which are nice a a bit different then Omani Greens or the Somalia. I am experimenting with some of the wild collected sap’s for new blends. Nice Etsy shop and a very informative blog. I will add the links onto the left hand side of our blog under suppliers and blogs. -Ross
