The brand I use says that about their product:

"Our Yerba Mate is 100% air dried through a process that use warm air instead of smoke. That drying system enable the leaves to be free of PAHs. This creates a safe, healthy and light tasting yerba mate."

I don't know if the claim is true or not.

Which brand do you use? I couldn't find an exact match via web search :(

https://matelibre.com/ out of Montréal. They even have them in cans.

Looking at their site, they apparently even make a vodka drink with them now. Uh, caffeine & alcohol drinks is usually not very well received by the government here. I wonder if it'll stir some political drama.

Interesting, thank you for the link.

I'm currently working my way through his podcast back catalogue, and am very much liking the content and his way of delivering it.

Must say I have never heard about smoked yerba mate though.

I wonder if that is something akin to how coffee is roasted?

edit: turns out the smoking is part of the common processing done to dry the leaves. I guess finding a supplier that dries via other methods would then be preferable.

Huberman is great but I wouldn't use any of his product or supplement recommendations, whether paid or not. I mean, Athletic Greens — WTH?

Do you know what his source is? He also recommends taking his preferred brand of dietary supplements which gives me pause about him.

Not sure if he cites this one specifically, but you can look at this one: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6443446/
