How long should you boil the root of Imperata cylindrica (bai mao gen) in water?

The boiling time of Imperata root (Bai Mao Gen) varies depending on its intended use, but generally ranges from 15 to 60 minutes. 1. Basic Boiling Time: As a traditional Chinese herb, Imperata root is usually boiled for about 30 minutes to ensure adequate release of its medicinal properties. 2. For Specific Symptoms: If used for conditions caused by the common cold, the boiling time can be appropriately reduced to around 15 minutes. If used for hemostasis (e.g., gastrointestinal bleeding, vomiting blood), it is recommended to boil for a longer duration, typically 30 to 60 minutes, to ensure effective hemostatic action.
