In the Salvia plant transmission, we spoke about the 'White Sage' which has been over-harvested + so the invitation is to either grow this where you live, if your local climate + soil is adapted or work with your native sages to create smudge bundles. I asked this question to a ceremonialist maybe 20 years ago in my homeland of Britain re if local sage could be used and the response i received was that the person had tried but that the climate then did not allow the development of sufficient essential oils for the sage to burn well and it proved difficult to light. With climate change, this reality will also have changed. Harvests can be timed for when the plant is at its peak and the sun has been particularly active. Where i live now in the South of France, the sunlight does allow the bundles i have created to catch light fairly easily 💚
