Cold extract
Some medicinal herbs may not be boiled since they loose their curative properties because of the heat.
We can still make a tea from these herbs, called cold extract or macerate. The recommended quantity of herb must be left in cold water to macerate for 8 – 12 hours, and then warm only the resulting liquid, until suited for drinking.
The mix from cold extract and infusion is considered the best utilization method of medicinal herbs.
Leave the herbs overnight in half the recommended water quantity, strain in the morning and boil the remaining herbs in the rest of the water and strain again.
Mix the cold macerate with the infusion. This method allows the use of the active substances soluble either only in cold or only in hot water.
