I know that there are some First Nations elders who do not approve of the sale of sacred plants, but there are also many who approve, so long as every step of the process is handled in a respectful and sacred manner. I procure several herbs for smudge, tea and smoking from Native peoples, and feel quite sure that the harvesting and bundling is done with pure heart and appropriate prayers. I continue to handle the herbs in a sacred manner. For me, "selling" is a form of energy exchange. It's the easiest one for most people to use, but it certainly isn't the only possibility. And I think that it is important for the exchange of energy to move in both directions, just like breath. Inhale, exhale. Give, receive.
