A decoction is a simmered water extraction used for tough plant material like roots, bark, and seeds — parts that a simple hot-water steep can’t fully break down. It’s one of the oldest and most straightforward ways to unlock the deeper compounds hidden inside dense herbs.

1. Chop or crush the root, bark, or seeds into small pieces to maximize surface area.
2. Combine about 1 tablespoon of herb per cup of water in a saucepan, starting with cold water.
3. Bring to a gentle simmer over medium-low heat.
4. Cover and simmer for 15–45 minutes, depending on the density of the plant material (tougher roots need longer).
5. Strain into a mug or pitcher, pressing out the liquid.
6. Drink warm, or refrigerate for later use.

Secret Tips

• Start with cold water and bring it up to temperature with the herb already in the pot — this allows for more even, gradual extraction than adding herb to already-boiling water.
• Chop roots and bark into small, uniform pieces; larger chunks can take significantly longer to fully extract.
• If a recipe combines roots with delicate leaves or flowers, simmer the roots first, then turn off the heat and add the leaves/flowers to steep in the residual warmth, protecting their more delicate compounds.
• A longer simmer isn’t always better — some compounds can start to break down with extended heat exposure, so stick to recommended times for each herb when possible.
