Cistanche tubulosa, also called Desert Ginseng, is a holoparasitic desert herb with thick, succulent, flowering spikes bearing dense yellow to brownish flowers emerging from sandy soils near its host shrubs. It is native to arid and semi‑arid desert regions of northwestern China and adjacent Central Asian deserts, where it has been integrated into Chinese and other Asian materia medica for roughly two millennia.
➡️ Its fleshy stems (Herba Cistanche) are harvested, sliced, and dried as a major yang‑tonic rich in phenylethanoid glycosides such as echinacoside and acteoside. It is used in functional foods, teas, and nutraceuticals, particularly in China and Japan, where extracts are incorporated into health beverages and anti‑aging formulations.
Beyond its medicinal stems, Cistanche tubulosa is cultivated as a drought‑tolerant desert crop that stabilizes sandy soils and supports ecological restoration in arid regions.
In traditional Chinese medicine, Cistanche (Rou Cong‑Rong) is classified as a Kidney yang tonic. It is also prescribed to strengthen the lower back and knees, enhance vitality, fertility, and resistance to aging, and moisten the intestines in the elderly. In some regional practices, the whole plant of Cistanche tubulosa is additionally used to manage diarrhea and other digestive complaints.
Documented pharmacological activities for Cistanche tubulosa and closely related Cistanche spp. include antioxidant, anti‑inflammatory, immunomodulatory, neuroprotective, anti‑aging, anti‑fatigue, hepatoprotective, osteoprotective, memory‑enhancing, antiapoptotic, and potential anticancer and metabolic‑regulating effects.
Cistanche appears to support testosterone by promoting its natural production and boosting growth hormone release. It’s thought to do this in part by increasing the activity of key steroidogenic enzymes and engaging the ghrelin receptor.
In one preclinical study, extract of Cistanche tubulosa increased serum testosterone and progesterone, alongside marked improvements in sperm count, motility, and morphology. These effects were associated with higher testicular expression of key steroidogenic enzymes such as CYP11A1 and CYP17A1, suggesting that the extract boosts sex hormone production by up‑regulating steroidogenesis in the testes.
Another examined the effects of a Cistanche tubulosa aqueous extract on the gut microbiome in and found that supplementation restored lactic acid bacteria levels, improved damaged intestinal morphology, and moderated antibiotic‑induced shifts in microbial metabolic pathways, suggesting a prebiotic‑like role in maintaining gut homeostasis.
