Whole leaf traditional tobacco can be used as an offering to ancestoral spirits. You may tie it (as pictured) and hang on the wall over the altar or simply place in a bowl that’s specifically for them.
It’s also burned when asking for guidance or as an offering. I gift these bundles to the spirits that reside on my land as a way of showing respect.
If you choose to burn it please Be responsible and use a fire safe container in a well ventilated area.
