Cistanche tubulosa (Desert Ginseng)
Desert adaptogen used for 1,800+ years in Chinese medicine to support testosterone, cognitive function, and gut health.
What the evidence says
Most Cistanche studies are mechanism or observational rather than RCTs that measure a clinical effect — keep findings provisional.
Most evidence is from high-quality randomised trials published 2012–2026 with a typical study size of 89 participants.
