You don't need every herb, bark, or root that has ever existed to produce powerful results. There are many readily accessible, or easily grown herbs, that can be used to help you achieve your goals, like Rosemary.

Rosemary is a powerful, high vibration herb used to cleanse and purify. It can be burned as an incense to clear away negative energy or placed under your pillow to help keep away nightmares. Use it in ritual baths for purification and drink it in teas to aid in dream recall. Rosemary can also be used as a substitute for other herbs.

Medicinally rosemary has anti-bacterial, anti-fungal, anti-inflammatory, anti-aging, and analgesic properties.
Remember, the source of power is inside the weaver. Herbs are tools that embody aspects of your desired result and assist you in achieving your goal. The energy and intent of the user will always affect the outcome.
