Cistanche Tubulosa and Testosterone: What the Evidence Actually Shows

If you follow the testosterone optimization space, you have probably encountered cistanche tubulosa. This desert plant has surged in popularity across social media and supplement shelves, with claims ranging from increased testosterone and improved libido to muscle growth and anti-aging effects.

But what does the evidence say? As with many supplements that go viral, the truth is more nuanced than the marketing. Cistanche has a long history in traditional medicine and some interesting preclinical research, but there is a large gap between that research and the claims made about healthy men. Importantly, there is also a regulatory safety question that most product pages do not mention.

What Is Cistanche Tubulosa?

Cistanche tubulosa is a parasitic desert plant that grows in arid regions of northwest China and Central Asia, attaching to the roots of host plants. In traditional Chinese medicine, cistanche stems are used as a tonic, and traditional uses include male sexual dysfunction. Those traditional claims are not the same as evidence from controlled trials.

The compounds that get the most attention are echinacoside and acteoside (also called verbascoside), phenylethanoid glycosides that have shown antioxidant and other activity in laboratory studies. Note that several species are sold as “cistanche”. Cistanche tubulosa and Cistanche deserticola are different plants, and research on one does not automatically apply to the other.

What the Animal Studies Show

The animal data is where the excitement comes from. It is worth reading carefully what these studies actually tested:

• Bisphenol A (BPA) toxicity in rats. Male rats were exposed to BPA, with or without cistanche tubulosa extract or echinacoside, for 42 days. The extract and echinacoside reversed the BPA-induced abnormalities in sperm and testicular structure and normalized serum testosterone, alongside increased expression of key steroidogenic enzymes.^[1]
• Diabetic rats. In rats made diabetic with streptozotocin, nicotinamide and a high-fat diet, echinacoside from a cistanche tubulosa extract improved blood sugar and restored hypothalamic gene expression and sex hormone levels.^[2]
• Hydrocortisone-induced injury in mice. Phenylethanol glycosides from cistanche tubulosa at moderate and high doses (145 and 289 mg/kg) improved reproductive function and the declined levels of LH and testosterone in the model mice; the low dose (72 mg/kg) had no significant protective effect.^[3]

The common thread is that these are injury models: the animals had damaged testes or disturbed hormones, and the extract restored them toward normal. That is not the same as raising testosterone above normal in a healthy man, and the doses given to rodents (tens to hundreds of mg per kg) cannot be translated directly to a human capsule.

The Human Evidence

Human research on cistanche tubulosa exists, but it has largely tested other outcomes:

• A placebo-controlled randomized trial in 26 people with pre-symptomatic or mild locomotive syndrome found that 12 weeks of cistanche tubulosa extract improved step width and gait speed in participants over 60, with no change in skeletal muscle mass and no notable adverse effects reported.^[4]
• A randomized, double-blind, placebo-controlled study combined cistanche tubulosa and ginkgo biloba extracts to examine cognitive function in middle-aged and elderly people.^[5]

One 8-week randomized trial in 48 men did measure testosterone, but it used Cistanche deserticola, a different species, at 5 g of extract twice daily (10 g per day) alongside resistance training. Participants had improvements in strength, and the abstract reports improvements in testosterone and cortisol, with benefits described in both trained and untrained men.^[9] That is one study of a different plant at a dose far higher than typical capsules, so it should not be taken as evidence for cistanche tubulosa supplements.

The honest summary is that human evidence that cistanche tubulosa raises testosterone is lacking.

Safety: What the European Regulator Said

Many product pages describe cistanche as completely safe. The European Food Safety Authority (EFSA) looked at a water extract of cistanche tubulosa stems as a novel food for use in food supplements. The applicant proposed a maximum intake of 2 g per day. EFSA noted that the extract is authorised as a prescription drug in China for vascular dementia, and that an integrated analysis of three studies covering 1,076 patients taking 1,800 mg per day reported 12 adverse events judged definitely, probably or possibly related, two of them severe (cerebral haemorrhage and epilepsy). EFSA also noted limitations in the toxicology studies and concluded that the safety of the novel food has not been established.^[6]

Those patients were older adults with vascular dementia, so the findings do not necessarily predict the risk in a healthy young man, and adverse events in a clinical study are not proof of cause. But it is a reason for caution, not for confidence, and it is a reason to talk to a doctor before taking cistanche, especially if you take medication or have a cardiovascular or neurological condition.

How Cistanche Compares to Ashwagandha and Tongkat Ali

Ashwagandha. A 2026 systematic review and meta-analysis of 23 randomized trials (1,706 participants) reported that ashwagandha increased testosterone in men by a mean of 57.43 ng/dL, but not in women, and also reduced cortisol, while noting heterogeneity and the need for more standardized trials.^[7] See our ashwagandha and testosterone guide, or tongkat ali vs ashwagandha for a head-to-head view.

Tongkat ali. A 2022 systematic review and meta-analysis of randomized trials (five in the meta-analysis) reported a significant increase in total testosterone with Eurycoma longifolia supplementation (standardized mean difference 1.35), while concluding that more research is required before clinical use.^[8] See our tongkat ali deep-dive.

This does not make those supplements risk free, and it does not make cistanche useless. It means that, on current evidence, cistanche is not a better-supported option for testosterone than alternatives, and that the supplement claims have run ahead of the research.
