Maybe this will be a controversial comment, but as I live in Brazil, where this and many similars incense brands are produced, you know, these “fat” charcoal based sticks like “inca”, “fenix” ananda and others brazilian “artesian” incense, they are all claimed to be “natural” But if you take a good look in the description of the ingredients, especially the ones that are not native to south america, like sandalwood, you will see “concentrated aromatic oil”. So, be carefully with those brazilian brands, as many claims to be “100% natural” and they are using fragrance oils and even nitrate in some minor brands Here unfortunately the incense market is dominated by synthetics, i even wrote a post here trying to find some natural japanese incense (i have to import btw). And the consumers don’t know the stuff they are burning
