White sage endangered? Since when? People all over are growing it in their gardens, including me.
But anyway, smudging with sage seems to work great for me. I use feathers to spread the smoke, and made a chant for each time I've done it. You can make your own, or use something like, "Negative is not welcome in my home. Be gone! As I cleanse this space, so shall it be done. As I cleanse, you are banished from me. As I will it, so mote it be." Then put up a protection of your choice. I use crystals in my windows. Hope this helps you. Blessed be...
