Protocol

Ask the plant first, and offer something before you take anything. Tobacco is what is most often offered here. Say who you are, and say what the medicine is for.

Harvest the mature plants and leave the small ones to grow. Never take the first plant you find, and never take all of them.

Take only what you will actually use. Medicine picked and then left to rot in a bag was taken for nothing.

Leave the ground as you found it. Put back any dirt you dug up, and return any plant material you do not use to the earth.

Do not gather beside roads, highways or trails, where the plants take up whatever has been sprayed or spilled there.

If you are not certain what a plant is, do not pick it and do not put it in your mouth. Ask someone. Being wrong in the field is how people get hurt.
