Cistanche is a worldwide genus of holoparasitic desert plants in the family Orobanchaceae. They lack chlorophyll and obtain nutrients and water from the host plants whose roots they parasitize.
Growth

Growing in arid climates, cistanche is a parasitic plant that connects to the conductive system of a host, extracting water and nutrients from the roots of the host plant. Cistanche is native to the Taklimakan desert region of Xinjiang Uyghur Autonomous Region northwest China where it grows on host desert plants tamarix and haloxylon ammodendron.[1]
Uses

Along with other members of the genus, Cistanche deserticola is the primary source of the Chinese herbal medicine cistanche (Chinese: 肉苁蓉, pinyin ròucōngróng). The main sources of cistanche are Cistanche salsa and Cistanche deserticola, although it may also be obtained from Cistanche tubulosa, Cistanche sinensis, and Cistanche ambigua. The drug, known in Chinese as suosuo dayun, is collected in spring before sprouting, by slicing the stems of the plant. Cistanche deserticola has been placed on CITES Appendix 2, a list of endangered species not banned from trade but requiring monitoring. With increased consumption of cistanche, the population of the species has decreased and its area of distribution has shrunk. Aside from over-collection or indiscriminate collection, an important factor in the diminished supply of cistanche is a loss of the host, Haloxylon ammodendron, which is widely used for firewood.
