Whole Herbs: Long Dan Xie Gan Tang formula is composed mainly of roots, so the boiling time should be at least 40 minutes, the dregs are strained out and the "tea" is taken warm or at room temperature. Good quality herbs will permit a second boiling.
Using a container made of ceramic, glass, or stainless steel (Don't use aluminum, iron or copper) boil 1 packet of herbs in 2-3 quarts of water until 2 cups of medicine remain. Adjust the lid to regulate water evaporation.
Strain herbs; save and refrigerate for a second boiling. Drink 1 cup in the AM. And 1 cup in the PM. If desired, repeat the following day, using the saved herbs from the refrigerator.
Tips on Boiling & Taking Chinese Herbal Decoctions
The potent odors and flavors of Chinese herbs are legendary. Boiling the herbs and drinking the tea will provide the fullest experience of these medicines. Be sure to ventilate the room to reduce the strong odors. Holding your nose (or your breath) while drinking the herbs virtually eliminates the taste, and taking something sweet afterwards will eliminate any aftertaste.
Always refrigerate herbs and medicine you intend to re-use or take later. Reheat refrigerated liquids to room temperature before drinking them.
