Decoction

Preparation method
2 steps
11 herbs prepared this way

Roots, bark, twigs, and berries usually require a more forceful treatment than leaves or flowers to extract their medicinal constituents. A decoction involves simmering these tougher parts in boiling water. Fresh or dried plant material may be used and should be cut or broken into small pieces before decocting. Like infusions, decoctions can be taken hot or cold.

Quantity

20 g dried or 40 g fresh herb (or mixture of herbs) to 3 cups (750 ml) cold water, reduced to about 2 cups (500 ml) after simmering (this makes 3-4 doses).

Steps

Place the herbs in a saucepan. Cover with cold water and bring to a boil. Simmer for about 20-30 minutes, until the liquid is reduced by about one-third.
Strain the liquid through a sieve into a jug. Pour the required amount into a cup, then cover the jug and store in a cool place.

Traditional amounts

Traditional texts describe the preparations below, and where those texts give specific amounts, the amounts are quoted here as part of that record. This is a record of historical practice, not a dosage recommendation - the figures are what the sources say, not what HerbMate tells you to take. Amounts, potency, and safe use vary enormously by preparation, plant part, and person.

Take 3-4 doses (2 cups/500 ml) each day.

Storage

Store in a covered jug in a refrigerator or cool place for up to 48 hours.
