Infusions and Decoctions

Infusions and decoctions are two methods of extracting the active constituents from a fresh or dried herb using water. Infusion is the best preparation method for flowers and leaves. Decoction is the best method for roots and seeds, with one notable exception: valerian root, which should be prepared as an infusion despite being a root.

Tools Needed

Saucepan or tea kettle
Quart-size mason jar with lid
Measuring spoon or scale
Fine mesh strainer

Instructions

Infusion: For Flowers and Leaves

Boil at least 1 quart of water in a saucepan or tea kettle.
In a quart-sized mason jar, add herbs. If using dried flowers or leaves, add 4 to 6 tablespoons. If using fresh, add 6 to 8 tablespoons.
Pour boiling water over herbs in the mason jar and cover.
After a minimum of 30 minutes, remove cover and strain through a fine mesh strainer.
Infusion is ready to drink. Most infusions can be stored in the refrigerator for up to 3 days.

Decoction: For Roots and Seeds

Measure herb root or seed and add to a 2-quart saucepan. If using dried roots or seeds, measure 4 to 6 tablespoons. If using fresh, measure 6 to 8 tablespoons.
Add a minimum of 1 quart of water to the saucepan.
Stir and gently bring water to a boil. Cover and simmer for 10 to 15 minutes.
Cool slightly and strain.
The decoction is ready to drink. Most decoctions can be stored in the refrigerator for up to 3 days.

Exception: Valerian root should be prepared as an infusion, not a decoction, despite being a root. Heat can degrade its active volatile compounds.

Herbs for Infusion (Flowers and Leaves)

Infusions extract the best from delicate plant parts. These herbs make excellent medicinal infusions. Explore each one in the Materia Medica:

Chamomile: Anti-inflammatory, calming, and gentle enough for daily use
Lemon Balm: Uplifting and nervine; steep for 30 or more minutes for full potency
Skullcap: Powerful nervine; best as a strong infusion
Passionflower: Aerial parts infuse well for anxiety and sleep support
Elderflower: Immune-supportive and delicate; a classic infusion herb
Mullein: Leaf infusion traditionally used for respiratory support
Thyme: Antimicrobial; excellent for lung and immune infusions
Lavender: Floral and calming; steep briefly to avoid bitterness

Herbs for Decoction (Roots and Seeds)

Decoctions extract medicine from tough plant material that needs heat and time. Explore these roots in the Materia Medica:

Ginger: Warming root; simmer 10 to 15 minutes for maximum potency
Burdock: Bitter root decoction traditionally used for liver and lymph
Dandelion: Root decoction for digestion and liver support
Licorice: Sweet root; use sparingly; can be added to decoctions as a harmonizer
Yellow Dock: Iron-rich root decoction traditionally used for liver and blood
