What is this page for?

Around that, we add a pharmacist’s high-level view of the product as a whole — what’s inside, the evidence for its stated use, how transparent the label is, and what safety data exists — so you can see the full picture in one place. It’s educational information from our licensed clinical databases and the clinical staff at HelloPharmacist — not medical advice — and we don’t sell or endorse products. Our editorial policy

HelloPharmacist Scorecard of Tu Si Zi by Herbal Terra
Our pharmacy team’s full take, with four database checks built into the cards below — a summary of what is known, not a grade of the product itself.
What’s inside
Full disclosure
This product contains one active ingredient: Tu Si Zi dried seed liquid extract, which is dodder seed. The liquid is suspended in menstruum, an inactive carrier.
Does it work?
Couldn't assess
The evidence for dodder isn't established yet in the data we hold. For both depression and atopic dermatitis (eczema), the research is too limited or unreliable to rate whether it works.
That doesn't mean it won't help you — it means we need more solid studies to know.
How safe is it?
Well-documented data
Dodder is generally well tolerated when taken by mouth. At high doses, it may cause intestinal colic (cramping) and diarrhea.
A combination product containing dodder seed extract has been reported to cause loss of appetite, mild indigestion, and a heavy feeling in the stomach, though it's unclear whether dodder alone caused those effects. Traditional use suggests keeping daily doses to no more than 8 grams of dodder aerial parts.
Human safety data are limited, so you should use this cautiously and under guidance from a healthcare professional. The safety information for pregnancy and breastfeeding is not reliable enough — it's best to avoid it during pregnancy and while breastfeeding.
Meds to double-check
No known interactions
No interactions are documented in our data for the ingredients we could check. That's not a guarantee that none exist — it means more safety research may be needed.
Check your exact medications with the tool on this page, and talk with your pharmacist if you have questions.
The bottom line
Scorecard at a glanceFully disclosed formula with no assessable stated purpose. No medication interactions are currently documented, and safety information is well characterized.
Tu Si Zi may be worth considering if you're interested in traditional herbal support, but the evidence for its effectiveness isn't established yet. Because human safety data are limited, talk with your pharmacist or doctor before starting, especially if you're pregnant, breastfeeding, or take other medications.
