HelloPharmacist Scorecard of Red Henna 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 contains one active ingredient: certified organic Red Henna dried leaf powder liquid extract. Henna has traditionally been used topically for skin and hair, though the evidence for its effectiveness in specific conditions remains limited.

The product also contains menstruum, an inactive ingredient used as a solvent or carrier.

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 Henna product and its label doesn't state a use — see Henna'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 doesn't establish that henna is reliably effective for chemotherapy-induced skin redness (acral erythema), contact dermatitis, chemotherapy-induced nerve damage (peripheral neuropathy), or wound healing. All of these have insufficient reliable evidence to rate.

The evidence, ingredient by ingredient Henna

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.

Henna applied to skin is generally well tolerated, but this product is a liquid extract — closer to oral use — and the safety data for taking henna by mouth is concerning. Oral henna has been linked to upset stomach, kidney injury and failure, hemolytic anemia (breakdown of red blood cells), and in rare cases, serious harm or death.

People with glucose-6-phosphate dehydrogenase (G6PD) deficiency — a genetic condition affecting how red blood cells handle certain compounds — face heightened risk. Pregnancy and lactation safety data advises against use during these times.

Because oral henna carries real risks and little safety data exists for this form, talk with your doctor or pharmacist before taking it.

Side effects, ingredient by ingredient Henna

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 — Henna.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: lithium.
  • For scale: 1 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 lithium, check with your doctor or pharmacist before starting this product — henna may increase lithium levels in your body and your dose might need adjustment.

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.

This product contains henna, which interacts with lithium and carries notable safety concerns when taken by mouth. If you take lithium, you'll want to check with your doctor or pharmacist before using this product.

Given the limited evidence for its effectiveness and the oral safety profile, it's worth discussing whether it's right for you with your own healthcare provider.

Lithium

Henna is thought to have diuretic properties. Theoretically, due to these potential diuretic effects, henna might reduce excretion and increase levels of lithium. The dose of lithium might need to be decreased.

Red Henna by Herbal Terra: Common Questions

Does Red Henna by Herbal Terra interact with any medications?
Yes. Based on its ingredients, Red Henna has a known interaction with 1 medication. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Red Henna contains a single active ingredient, and that one ingredient can interact with many different medications on its own. We check it against each medication and show the mechanism responsible.
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.
Is this henna safe to take by mouth?
Not according to the safety data we hold. Oral henna can cause upset stomach, kidney injury, and breakdown of red blood cells. In rare cases, it's been linked to serious harm. Topical henna (on skin or hair) is generally considered safer, but this is a liquid extract meant for internal use, so talk with your doctor first.
Can I use this if I have G6PD deficiency?
No, not without talking to your doctor. People with G6PD deficiency — a genetic condition — face a heightened risk of red blood cell breakdown when exposed to henna, especially orally. This is a serious concern you need to discuss with your healthcare provider.
Can I take this while pregnant or breastfeeding?
The safety data advises against use during pregnancy and lactation. Talk with your doctor or pharmacist about whether it's appropriate for you in these situations.
Does this actually work for skin or wound healing?
The evidence we hold doesn't establish that henna is reliably effective for those purposes. The ratings are insufficient — meaning we don't have enough reliable data to say yes or no.
What's the difference between this and topical henna products?
This is a liquid extract designed for internal use. Topical henna (creams, pastes applied to skin) is considered generally safer and has a clearer history of use. The oral form carries more documented safety risks, so the concerns are different.
What does 'menstruum' mean on the label?
It's the liquid used to extract and carry the active henna in the product — essentially a solvent or carrier. It's not an active ingredient.
