Can you inhale sumac or is this a different species than the one that gives the itchy rash?
Staghorn sumac is not poisonous. It mellows out the mullein, adds some depth and helps keep the burn even.
Even so, don't inhale. coltsfoot stimulates coughing. If you need the medicinal properties, a tea is a better use of the herbs.
I'm gonna have to try that blend myself, and those pipes are way cool. Did you make 'em?
I did. Seasoned maple works very well. I was going to work up a bunch for trades, but ran out of seasoned branches.Next year
