A decoction is a method for extracting oils, volatile organic compounds, and other chemical substances from hard plant materials such as roots and bark.
When making herbal decoctions, the ingredients are in most cases 30g (2 tablespoons) of dried herb and 500 ml of water.
Simple Decoction
1. Crush and mash the herbs
2. Place them in a bowl and add boiling water
3. Cover the bowl with a lid and let it stand overnight
4. Replace the water that has been lost by evaporation
5. Place the water with the herbs in an enamel pan.
6. Bring to boil slowly
7. Simmer for about 20 minutes while keeping the lid covered
8. Using a muslin cloth, strain and press all the liquid
Reduced Decoction
Follow the simple decoction’s procedure until step 5.
6. Heat until steam comes out while keeping covered with a lid
7. Turn the heat low and steam for about 1 hour until you see that the liquid has gone down to 250 ml.
8. Using a muslin cloth, strain and press all the liquid
When stored in a cool place, this will keep for around 4-5 days.
Preserved Decoction
You can preserve a decoction longer either by:
- Adding 450g sugar or honey to 200 ml of decoction. This should be taken in dosages of 1 teaspoon 3 times daily.
- Adding liquors such as vodka or brandy at a ratio of 1:2. This should be taken in dosages of 1/4 cup daily.
- Pouring a very thin layer of vegetable oil on the surface of the decoction and then sealing. When need to use arises, just draw the oil off and pour the decoction from it. It should be taken in measurements of 3 teaspoons 3 times daily.
