What’s inside

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.

Tu Fu Ling is a single-ingredient liquid supplement containing sarsaparilla root extract. The liquid also includes alcohol, water, and glycerin as inactive ingredients.

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 Sarsaparilla product and its label doesn't state a use — see Sarsaparilla'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 for sarsaparilla in cancer, psoriasis, and rheumatoid arthritis is not established in the data we hold—we have insufficient reliable evidence to rate it for any of those uses. If you're considering this product for a specific health concern, that's a good conversation to have with your pharmacist.

The evidence, ingredient by ingredient Sarsaparilla

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.

Sarsaparilla appears to be low-risk in food amounts, but safety data for supplement doses in humans are limited. We don't have enough information to recommend it during pregnancy or while breastfeeding—talk with your doctor or pharmacist about whether it's right for you.

Occupational exposure to sarsaparilla root dust can trigger rhinitis and asthma symptoms, though this is relevant mainly to people who work with the raw material.

Meds to double-check

Moderate interaction found
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 — Sarsaparilla.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: heart-rhythm medications; lithium.
  • For scale: 2 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.

Check your exact medications if you take lithium or digoxin (Lanoxin). Both have Moderate-severity interactions with sarsaparilla because of its diuretic effects.

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.

Tu Fu Ling is a straightforward single-ingredient product, but it's not for everyone. If you take lithium or digoxin, you need to check with your pharmacist before adding this.

Pregnant or breastfeeding? The safety data aren't there yet—ask your doctor first.
