Place a mason jar onto a kitchen scale and hit "tare" to zero out the weight.
Add your echinacea leaves and flowers to the jar, packing down gently, if needed.
Remember the weight (in ounces) of the flowers and leaves, then add double the weight (in ounces) of vodka.
Add lid and give the jar a good shake to start the process.
Remove the lid and push any flowers or leaves below the surface of the alcohol, replace lid and set on the counter, out of direct sunlight, for two weeks.
Each time you walk by the jar, give it a good shake (at least once daily).
Tincture is ready in 14 days.
