IV. Plant Herstory:
The Europeans were the first to discover Damiana’s medicinal
properties around the 16th and 17th century. Damiana was discovered to the Europeans while roaming in what is now the area of Baja, California- which back then was Mexico. However, it wasn’t introduced, to America until the late 19th
century in the year 1874, by Dr. F. O. St. Clair.
Damiana was the
favorite sex herb of the Aztecs and Mayans and played a part in their religious
ceremonies. It has been used by breeders to improve the chances of conception in high-strung livestock.
VI. Cultivation and Propagation:
Damiana grows wild in the subtropical regions of the
Americas and Africa, specifically the Gulf of Mexico, southern California,
northern Caribbean Islands and Namibia. Damiana prefers a hot, humid climate. The leaves are harvested when the herb is in flower in the summer. Damian can be planted outdoors in the West and Southwest after the early spring or late winter- after the last frost has ended. Damian is propagated by seeds and
cuttings. She is able to grow in both rich and sandy soil as long as there is good drainage in whatever soil she may be planted in. Damiana needs to grow in
an area that gets about 8 to 10 hours a day of sun. (Damiana is very hardy and if damaged by the frost she may still be able to survive the winter freeze although everything above ground may die, her roots may still survive).
VII. Wild crafting and domesticated harvest:
The leaves and tops are harvested while the plant is in flower. As some of the
active principle is volatile, the tops are preferably dried in the shade,
without the application of heat.
