From plant to use
Simmering roots, bark and seeds so they release their flavour and compounds.
Hard plant parts give up little in a short infusion. That is why many traditions gently boil roots, bark, seeds and berries: a decoction. Think of ginger root, cinnamon bark and the herbal formulas of Ayurveda and traditional Chinese medicine.
