HelloPharmacist Scorecard of Yi Yi Ren 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
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 is a liquid extract of Job's Tears seeds (Yi Yi Ren)—a traditional grain also called adlay. The single active ingredient is the dried seed material concentrated into liquid form.

The only other ingredient listed is menstruum, the liquid used to extract the active material.

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 Job's Tears product and its label doesn't state a use — see Job's Tears'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 data we hold rates Job's Tears for hypoglycemia (high blood lipids)—the evidence is insufficient to make a reliable claim about whether it works for that purpose. We don't have effectiveness information on file for other potential uses.

The evidence, ingredient by ingredient Job's Tears

How safe is it?

Some data gaps
Safety Information · database check
Some gaps

Safety data exists for these ingredients, but with some important gaps.

Why this rating?
  • We hold adverse-effect (side-effect) data for 0 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.

Job's Tears is generally well tolerated when used as a cooked food, though concentrated supplement evidence is limited. The safety data advises against use in pregnancy, and there isn't enough reliable data to know if it's safe during breastfeeding.

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

Side effects, ingredient by ingredient Job's Tears

Meds to double-check

Moderate interaction found
Known Interaction Concern · database check

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 — Job's Tears.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: diabetes medications.
  • For scale: 128 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 medications against this product if you take antidiabetes drugs (insulin, glimepiride, glyburide, pioglitazone, and others), theophylline, dextromethorphan cough suppressants, muscle relaxers like chlorzoxazone, or heart medications like diltiazem. All of these have documented Moderate-severity interactions with Job's Tears.

The bottom line

Scorecard at a glanceFully disclosed formula with no assessable stated purpose. Moderate medication interactions have been identified, and some safety-information gaps remain.

Yi Yi Ren may be worth exploring if you're interested in traditional herbal approaches, but several documented interactions with common medications—especially blood sugar drugs, cough suppressants, and heart medications—mean you'll want to check your specific prescriptions first. Talk with your pharmacist before you start, especially if you're taking antidiabetes medication or any of the drugs listed above.

Antidiabetes Drugs

Preliminary evidence shows that constituents of Job's tears might have hypoglycemic effects. Theoretically, concomitant use with drugs that decrease blood glucose levels might increase the risk of hypoglycemia. Some antidiabetes drugs include glimepiride (Amaryl), glyburide (DiaBeta, Glynase PresTab, Micronase), insulin, pioglitazone (Actos), rosiglitazone (Avandia), chlorpropamide (Diabinese), glipizide (Glucotrol), tolbutamide (Orinase), and others.

Likelihood Possible Evidence D
Chlorzoxazone (Parafon Forte, Paraflex)

Animal research suggests that Job's tears might enhance absorption of chlorzoxazone in the small intestine. Single dose and short-term oral administration of Job's tears bran ethanolic extract along with oral administration of a five-drug cocktail containing chlorzoxazone increases chlorzoxazone peak plasma concentration and area under the plasma concentration-time curve (AUC) without altering major cytochrome P450 activities in the liver. This effect has not been reported in humans.

Likelihood Possible Evidence D
Dextromethorphan (Robitussin Dm, Others)

Animal research suggests that Job's tears might enhance absorption of dextromethorphan in the small intestine. Single dose oral administration of Job's tears bran ethanolic extract along with oral administration of a five-drug cocktail containing dextromethorphan increases dextromethorphan area under the plasma concentration-time curve (AUC) without altering major cytochrome P450 activities in the liver. This effect has not been reported in humans.

Likelihood Possible Evidence D
Diltiazem (Cardizem, Others)

Animal research suggests that Job's tears might enhance absorption of diltiazem in the small intestine. Single dose oral administration of Job's tears bran ethanolic extract along with oral administration of a five-drug cocktail containing diltiazem increases diltiazem peak plasma concentration and area under the plasma concentration-time curve (AUC) without altering major cytochrome P450 activities in the liver. This effect has not been reported in humans.

Likelihood Possible Evidence D
Theophylline

Animal research suggests that Job's tears might enhance absorption of theophylline in the small intestine. Single dose and short-term oral administration of Job's tears bran ethanolic extract along with oral administration of a five-drug cocktail containing theophylline increases theophylline peak plasma concentration and area under the plasma concentration-time curve (AUC) without altering major cytochrome P450 activities in the liver.

Where does this information come from?
The product label data comes from the NIH Dietary Supplement Label Database (DSLD); the interaction data is built on the Natural Medicines database and reviewed by HelloPharmacist pharmacists.
