About this collection
Single-ingredient herbal powders, milled fine and sold without anything added to them. The point of a single-ingredient powder is that you can see exactly what you are putting on your skin, and mix it to the strength your skin tolerates rather than the strength a manufacturer chose.
This collection is small on purpose and grows as formulations are finished. Everything in it is for external use, and the directions on each product page say how often is sensible.
