Rosemary is known to help sharpen mental clarity and stimulate brain function.
The needles of the delightfully fragrant rosemary plant can be used in a tea to treat digestive problems. The same tea can also be used as an expectorant and as a relaxing beverage that is helpful for headaches. Other healing uses include improving memory, relieving muscle pain and spasms, stimulating hair growth, and supporting the circulatory and nervous systems.
