Wort Moon

The full moon that falls in Leo is sometimes called the Wort Moon because its waxing is the auspicious time to gather certain worts, or herbs useful for the leafy part that grows above the ground. (Dried herbs of this type are medicinally and magically effective for only about a year after they are picked, a fact that is ignored by most businesses that market them.) Two herbs traditionally associated with this time were mugwort and vervain.

Mugwort is plentiful in California, and known since Native American times for its power to induce dreams. Drink it as a tea, and fall asleep intending to dream what you need to know. Some herbals give warnings about its possible toxicity, but you would probably have to drink gallons of the stuff to do any harm, and there's no reason why anyone would do that. You'd be up all night peeing, and never get any dreams at all.

Vervain is traditionally used for kidney stones and bladder problems, also to drive away vampires. The Iroquois used it to drive away anybody they didn't want to deal with, but this strategy doesn't seem to have stood the test of time. It apparently works better on vampires than on white people. Vervain has general protective qualities, though, and is also used in divination; you can see the future by gazing into a fire through vervain. Or add some to your mugwort tea for prophetic dreams.
