Full moon water is a preferred ingredient in many potions because it is charged with the natural powers of the moon. You can make full moon water by placing tap or spring water outside (in a sealed, clear container) with the full moon shining down upon it. You can reserve this specially charged water for washing your tools, herbs, or other ingredients, or you can use it in the potions themselves. For example, I use full moon water in my tea to give it extra power. Full moon water is best used in potions designed to aid in perfecting ideas, working on positive aspects, increasing psychic and physical energy, and enhancing creativity.
New moon water is ideal for potions relating to healing and resting. It is made in the same way as full moon water, but instead of a full moon, you let the light of a new moon shine on it.
