HelloPharmacist Scorecard of Buchu 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: wildcrafted buchu leaf liquid extract. Buchu is a traditional herb used for its diuretic and urinary tract support properties.

The liquid extract is prepared from the dried leaves of Agathosma betulina. The only other ingredient listed is menstruum, a neutral liquid used to extract and preserve the herb.

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 Buchu product and its label doesn't state a use — see Buchu'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.

We hold no effectiveness ratings in our data for buchu, so we cannot speak to how well it works for any condition. If you're considering it for a specific purpose, your pharmacist or doctor can help you weigh what traditional use suggests against what clinical evidence shows.

The evidence, ingredient by ingredient Buchu

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.

Buchu is generally used in food amounts and is generally well tolerated at those levels, but medicinal doses lack strong safety data. The essential oil can be irritating.

During pregnancy, buchu is rated likely unsafe due to traditional concern that it may affect the uterus — the safety data advises against it. For breastfeeding, there isn't enough safety information to know either way, so talk with your doctor or pharmacist before use.

Side effects, ingredient by ingredient Buchu

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 — Buchu.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; lithium.
  • For scale: 482 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.

Before taking buchu, double-check with your pharmacist if you take any drugs that damage the liver, blood thinners or antiplatelet drugs like warfarin or aspirin, or lithium. These interactions are rated Moderate — your liver function and bleeding risk could be affected.

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.

Buchu may help with urinary tract health, but it's not for everyone. If you take blood thinners, medications that strain your liver, or lithium, you need to check with your pharmacist first.

Pregnant people should avoid it, and those breastfeeding should ask before starting.

Anticoagulant/Antiplatelet Drugs

Buchu may have antiplatelet effects. Theoretically, buchu may enhance the effects of anticoagulant or antiplatelet drugs and increase the risk of bleeding in some patients. Some anticoagulant or antiplatelet drugs include aspirin, clopidogrel (Plavix), dalteparin (Fragmin), enoxaparin (Lovenox), heparin, ticlopidine (Ticlid), warfarin (Coumadin), and others.

Likelihood Possible Evidence D
Hepatotoxic Drugs

Buchu contains pulegone, a known hepatotoxin. There is some concern that buchu may adversely affect the liver, especially when the leaf is used in large doses or the oil is ingested. Theoretically, concomitant use with hepatotoxic drugs might increase the risk of liver damage. Some of these drugs include acarbose (Precose, Prandase), amiodarone (Cordarone), atorvastatin (Lipitor), azathioprine (Imuran), carbamazepine (Tegretol), cerivastatin (Baycol), diclofenac (Voltaren), felbamate (Felbatol), fenofibrate (Tricor), fluvastatin (Lescol), gemfibrozil (Lopid), isoniazid, itraconazole, (Sporanox), ketoconazole (Nizoral), leflunomide (Arava), lovastatin (Mevacor), methotrexate (Rheumatrex), nevirapine (Viramune), niacin, nitrofurantoin (Macrodantin), pioglitazone (Actos), pravastatin (Pravachol), pyrazinamide, rifampin (Rifadin), ritonavir (Norvir), rosiglitazone (Avandia), simvastatin (Zocor), tacrine (Cognex), tamoxifen, terbinafine (Lamisil), valproic acid, and zileuton (Zyflo)

Likelihood Possible Evidence D
Lithium

Buchu is thought to have diuretic properties. Theoretically, buchu might reduce excretion and increase levels of lithium. The dose of lithium might need to be decreased.

Yes. Based on its ingredients, Buchu has a known interaction with 481 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Buchu 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 buchu safe in pregnancy?
No. Buchu is rated likely unsafe in pregnancy because it has traditionally been thought to affect the uterus. If you're pregnant or planning to become pregnant, avoid it and talk with your doctor or pharmacist.
Can I take buchu while breastfeeding?
There isn't enough safety information available to know whether buchu is safe during breastfeeding. Talk with your doctor or pharmacist to decide what's right for you and your baby.
What is buchu used for?
Buchu is a traditional herb known for its diuretic properties — it helps your body shed water. It's also traditionally used to support urinary tract health, though we don't hold effectiveness ratings for it in our data.
Is the essential oil different from this extract?
Yes. This product is a liquid extract from the dried leaves. The essential oil is more concentrated and is more likely to be irritating. Medicinal doses of buchu in any form lack strong safety data.
Will buchu thin my blood?
Buchu may have antiplatelet effects, which means it could boost blood-thinning drugs and raise bleeding risk. If you take aspirin, warfarin, or similar medications, check with your pharmacist before starting buchu.
Does this product have fillers?
The only other ingredient is menstruum, which is the liquid used to extract and preserve the buchu leaf. There are no fillers like cellulose or magnesium stearate listed.
