It must be dried lotus leaves to make tea. It's summer now, so you can pick lotus leaves by yourself, especially those with big leaves, neat leaves and green colors. Wash and dry in the sun until 70% to 80% dry. Tear the dried lotus leaf into small pieces and seal. When making tea, you can put 15-30 grams every day, or you can put a bag of tea leaves in a teapot or a big teacup and pour boiling water. It is best to stew for 5-6 times. Moreover, even if the tea is cold, its effect will not change. It is best to drink it before meals. It will take some time for this method to be effective. Moreover, lotus leaves have the effects of clearing heat and promoting diuresis, promoting hair growth and clearing yang, cooling blood and stopping bleeding, and are also very beneficial to the body.
