Turnera diffusa, commonly known as Damiana, is an aromatic herb native to Central and South America. Damiana users seek it out for sedative and aphrodisiac properties. Considering this purpose, damiana is also referred to as Turnera Aphrodisiaca, and it was reportedly used by the Mayans to enhance sexual experiences. Damiana?s reputation as a sex herb may be connected to reports that it dilates blood vessels. Damiana reportedly mixes well with other calming herbs such as passion flower, skullcap and chamomile, and it is a common additive to smoking blends or teas. In addition to the aforementioned uses, damiana is also employed as a cough suppressant, stomach herb, anti-depressant herb and an anti-anxiety herb. It is said to help balance moods and female hormone levels while relieving constipation. Some users also find that it helps promote restful sleep. Damiana should be avoided by pregnant women. It has also been linked to fluctuations in blood sugar levels, so it should also be avoided by individuals suffering from diabetes or hypoglycemia.
