Hot water brewing, warm the teapot and teacups with hot water, and drain them afterwards. Take out 2-4g of lavender tea, put it into the warmed pot and slowly fill it with 500ml of boiling water, the lavender tea aroma will then waft out. Leave for about 3 minutes and drink. Back brewing for the second time will take about 7 minutes, and the third time should be left to stand for about 10 minutes. If you put in the boiling water first and then add the herbal tea, it will retain the color of the herbal tea and is more resistant to steeping
