You can make a tea from the leaves and use it in a cleansing bath. To make the tea, add two tablespoons of the dried leaves to two cups of boiling water. Allow the mixture to steep for ten minutes, strain it, and then pour it into your bathwater.
You can also dry the leaves and use them as incense to cleanse your home and raise the spiritual vibrations. Or add the flowers to other incenses to add strength and purity.
Nasturtium flowers will help you invite magick and power of spirit into your life. Simply allow yourself to connect with their essence by opening your heart and your mind.
