Of course it is effective, but we should pay attention to a few points. In some places, peach blossoms are gone on the third day of the third lunar month or there is no need to use some methods. Choose a good time and place, preferably a sunny day when the local peach blossoms are in full bloom, put them in a clean urn and bury them under the peach trees. No water can enter them, they must be completely isolated from the air. You can't choose a chicken with black hair and black skin. Skin and feet must be black. Stir the peach blossom and chicken blood evenly, and the blood should not be too much or too thin. It will be worse after being applied to the face. It takes three days to wash it. There is a record in "The Secret Garden of Ancient and Modern Times": "Peach blossoms are harvested on March 3, chicken blood is harvested on July 7, and two flavors are applied, and then the color is bright on the third day."
