Full disclosure
Ingredient Transparency · database check
Full

Every active ingredient lists its own amount on the label.

Why this rating?
  • The label discloses an exact amount for 1 of its 1 active ingredient.
  • No proprietary blends here — you can verify the dose of every single component.

This product contains one active ingredient: wildcrafted Zhu Ru (Bambusa tuldoides) as a dried shavings liquid extract. Bamboo is the whole source material here.

The liquid also contains menstruum, an inactive ingredient used to extract and carry the bamboo.

Does it work?

Couldn't assess
Evidence for Intended Use · database check
By FDA rules, dietary supplements can’t claim to treat, cure, or prevent disease — so labels speak in careful marketing language. We discern each product’s intended use from its name, label claims, and label statements, then grade the clinical evidence for that use. How these ratings are computed
Not assessable

This is a single-ingredient Bamboo product and its label doesn't state a use — see Bamboo's own graded uses on its monograph.

Why this rating?
  • We looked at the product name, claims, and label statements and couldn't find a stated purpose to grade.

The evidence we hold on bamboo for dental caries prevention is insufficient — we don't have enough reliable data to say whether it works for that purpose. If you're considering this supplement for a specific health goal, talk it over with your doctor or pharmacist about whether the current evidence supports it.

The evidence, ingredient by ingredient Bamboo

How safe is it?

Well-documented data
Safety Information · database check
Well characterized

Adverse-effect, pregnancy, and general safety data are on file for most of these ingredients.

Why this rating?
  • We hold adverse-effect (side-effect) data for 1 of the 1 matched ingredient.
  • Pregnancy & breastfeeding safety ratings cover 1 of 1.
  • General safety write-ups exist for 1 of 1.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Properly cooked bamboo shoots are commonly eaten as food, but supplement safety hasn't been well studied. Raw shoots can be toxic.

The product data also notes that bamboo shoots contain cyanide glycosides, though the hydrogen cyanide is eliminated by boiling, fermentation, or superheated steam drying — the processing methods used in supplements. Topically, bamboo shoots have caused contact dermatitis in rare cases.

For pregnancy: there isn't enough safety data on bamboo supplements, so concentrated forms like this extract should be avoided during pregnancy. For breastfeeding: safety is unknown, so avoid concentrated bamboo extracts unless your doctor clears it specifically.

If you're pregnant or breastfeeding, check with your doctor or pharmacist before taking this product.

Known Interaction Concern · database check
Moderate identified

The most serious documented interaction for these ingredients is Moderate. Check your medications for a personalized result.

Why this rating?
  • 1 of the 1 matched ingredient can interact with medications — Bamboo.
  • The most serious interaction on file is rated Moderate.
  • For scale: 5 individual medications appear in the full list. A big number alone doesn't make a product dangerous — what matters is whether YOUR medication is on it, so run yours through the interaction checker on this page.

If you take antithyroid drugs (medications that slow an overactive thyroid), check with your doctor or pharmacist before using this product. Long-term bamboo use may increase how these medications work and raise the risk of side effects, including hypothyroidism.

The bottom line

Scorecard at a glanceFully disclosed formula with no assessable stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.

Zhu Ru is a single-ingredient bamboo extract used traditionally for oral health, though reliable evidence for that use is lacking. The main concern is a moderate interaction with antithyroid medications, which requires your doctor's attention if you take them.

Pregnancy and breastfeeding safety data is too limited to recommend it without clearance from your own healthcare provider — talk it over with them before starting.

Antithyroid Drugs

Theoretically, long-term bamboo use might increase the effects and adverse effects of antithyroid drugs, possibly leading to hypothyroidism.
Animal research suggests that long-term consumption of bamboo shoot can decrease thyroid peroxidase activity, as well as levels of thyroxine (T4) and triiodothyronine (T3). This effect has not yet been reported in humans.

Where does this information come from?

Can I take this while breastfeeding?
Safety during breastfeeding is unknown. The data recommends avoiding concentrated bamboo extracts unless your doctor has cleared it specifically. Check with your doctor or pharmacist before starting.
