I have used cinnamon for fungus gnats, I would just blow a table spoon of it in front of my fan, and the powder would go everywhere.
The gnats and also mites hate it, but it starts to smell real funky after a while, especially when combined with Neem oil, and you definitely need to wash your buds after harvest lol.
I eat a lot of curry, curcumin is notoriously hard for the liver to process even with the black pepper.
I use a supplement called Theracurmin that is the most easily absorbed curcumin and excellent for reducing inflammation as are all types of spices used in curries.
