These two types are also sources of tannin dyes, and a number of medically used extracts can be taken from them. A certain variety of Tamerisks, namely T. mannifera, excretes a white substance that the Bedouins call manna, a sweet, gummy white substance which some have likened to the manna in the biblical book of Exodus on which the Israelites survived while wondering in the wilderness. Comically enough, the seedpods of some tamarisks can be inhabited by insect larvae and made into a "jumping bean- to entertain children (Moore, Illustrated Encyclopedia, Vol. 2, pp 196, 219).
Fairly recent immigrants to the United States, Tamerisks were introduced sometime in the 1800's when they were first used as landscaping décor, primarily in California. Four separate tamerisk species were introduced, all of which were purely decorative and could be cultivated into small trees or shrubs. They were imported from the Mediterranean, the Gobi Desert, the Tigris-Euphrates River Basin, and Somalia, respectively (Moore, Plant Life 110, 111, 166, 169). Eventually, these forms of flora were used as windbreaks. Being a hardy plant with a massive root system, it also helps prevent soil erosion along rivers. Due to its adaptive qualities and ability to dwell both in deserts and along rivers, tamarisks rapidly spread across the country. The Southwest, with its warm climate, has provided an ideal home for the tamerisk. However, they can be found all across the southern parts of the country from South Carolina to California and as far north as the Canadian border in most of the Western portion of the United States (Muzika and Swearingen). .
As the tamerisk has become more prevalent, its negative aspects have severely overshadowed its meager positive attributes. In fact, the tamerisk is now classified as one of the ten most noxious weeds in the country.
