While some say that May water should be collected on the first of May, a day celebrated as Beltane by Pagans, it does not typically rain on that day in many parts of the world. Others say that dew ay be collected rather than rain, but just how much dew are you going to have to collect for that. One solution I heard of involved hanging white sheets out and then wringing the dew from the on May Day, but that also implies that one lives in a damp region. A better solution is to collect water from the first rain in May, whenever that may be. May water can be used for spiritual cleansing, fertility, and youthfulness. You may bottle it up to use throughout the year; a bit added to a bath or splashed on your face should make you feel youthful and energized.
