Cistanche tubulosa (Rou Cong Rong)
What it is
A desert parasitic plant used in TCM as a kidney yang and essence (Jing) tonic for longevity and virility. Contains echinacoside and acteoside with demonstrated neuroprotective and anti-fatigue effects in animal models. A 2024 pilot trial found 100 mg/day improved cognitive scores in mild cognitive impairment. Often combined with Epimedium in traditional formulas. Sustainability concerns due to wild harvesting.
Dose
100–450 mg/day standardised extract (15% echinacosides); traditional decoction 9–15 g/day
Time of day & tips
Take with food in the morning. Choose sustainably cultivated sources. Allow 4–8 weeks for cognitive or vitality effects. Traditional TCM practice combines it with other kidney-tonifying herbs.
