HelloPharmacist Scorecard of Gan Di Huang Alcohol Free 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 has one active ingredient: rehmannia glutinosa root extract (in dry form). Rehmannia is a traditional plant used in herbal medicine for a range of conditions.

The extract is suspended in a base of glycerin and water — there are no other active ingredients in this product.

Does it work?

Moderate evidence
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

This product doesn't appear to be marketed for a specific use, so we graded Rehmannia's overall clinical evidence instead.

Moderate

Some clinical evidence supports Rehmannia for:

Why this rating?
  • We looked at the product name, claims, and label statements and couldn't find a stated purpose to grade.
  • Since the label doesn't commit to one use, we graded the ingredient's overall clinical evidence instead.
  • On file: Chronic kidney disease (CKD) — rated "Possibly Effective" (Natural Medicines).

The evidence for rehmannia's effectiveness is limited and mixed. For chronic kidney disease (CKD), it's rated possibly effective — meaning there's some clinical support, but it's not considered proven.

For aplastic anemia, atopic disease, osteoporosis, diabetes, and diabetic nephropathy, the evidence isn't established well enough in the data we hold to rate it either way. Talk with your doctor or pharmacist about what you're hoping to address and what your other options are.

The evidence, ingredient by ingredient Rehmannia

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.

Human safety data for rehmannia are limited, and product quality varies between manufacturers, so caution is warranted. The safety information advises against use during pregnancy and while breastfeeding — there isn't enough data to know whether it's safe in either situation.

If you're pregnant, planning to become pregnant, or breastfeeding, speak with your doctor or pharmacist before starting this product. No adverse effects were reported in the data we hold, but that doesn't mean they can't happen.

Side effects, ingredient by ingredient Rehmannia

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 — Rehmannia.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: diabetes medications.
  • For scale: 258 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 with your pharmacist if you take blood pressure medication (antihypertensives) — rehmannia may lower your pressure further. Also check if you take diabetes medication — it could increase the risk of low blood sugar (hypoglycemia).

The bottom line

Scorecard at a glanceFully disclosed formula with some supporting evidence behind its ingredients' uses. Moderate medication interactions have been identified, and some safety-information gaps remain.

Gan Di Huang Alcohol Free is a single-ingredient rehmannia product that may help with chronic kidney disease, but the evidence for other conditions is unclear. If you take blood pressure or diabetes medication, you need to check this product with your pharmacist before starting it.

Avoid it during pregnancy and while breastfeeding unless your doctor says otherwise.

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.
What is rehmannia, and what is it used for?
Rehmannia is a plant root extract used in traditional herbal medicine. In this product, it's studied mainly for chronic kidney disease, where there's some clinical support. It's also been tested for other conditions like anemia, allergic disease, bone health, and diabetes, but the evidence for those uses isn't established yet.

The safety information advises against this product during pregnancy and while breastfeeding because there isn't enough data to know if it's safe. Talk with your doctor or pharmacist about whether this is right for you in these situations.
Are there any side effects?
The data we hold don't report any adverse effects, but that doesn't mean they can't occur. Human safety information for rehmannia is limited overall, so if you notice any unusual symptoms after starting, let your pharmacist or doctor know.
How many active ingredients are in this product?
Just one — rehmannia glutinosa root extract. The other ingredients are glycerin and water, which are inactive carriers.
