Artemisia argyi （Asiatic wormwood) is a medicinal herb used in TCM. In TCM we use Artemisia argyi for moxa treatment。
We also can use leaves to a medicinal herbal tea. But the taste of dried artemisia leaves without being processed in advance is hard to drink because of its very very bitterness in taste.
The pre-processed step helps to reduce the bitterness, afterward stir fry in a dry wok with sliced gingers till all ingredients are fully dried.
Today I used about 2g, water temperature is below 90C, quickly brewing and quickly filter out, I am amazed by its gentle sweetness instead of bitterness. Multiple brewing is possible with this medicinal herbal tea.
