HelloPharmacist Scorecard of Full Spectrum Buchu Leaf Extract 100 mg by Swanson

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.

From our pharmacy team — supplement deep dive

Generated from HelloPharmacist’s pharmacist-curated databases and editorial rules · Last generated Jul 11, 2026

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: buchu leaf extract at 100 mg per capsule. Buchu is a plant traditionally used for its diuretic (water-removing) properties.

The capsule itself is filled with inactive ingredients — rice flour, gelatin, maltodextrin, and calcium palmitate — which are binders and fillers.

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

We hold no graded evidence for this product's ingredients for its stated purpose.

Why this rating?
  • The label markets this product for: Total wellness for mind, body and home.
  • Our graded evidence for these ingredients doesn't cover that particular purpose.

We hold no effectiveness ratings for buchu leaf extract in our data, so the evidence for what it does isn't established in the information we have on file. If you're considering it for a specific health goal, ask your pharmacist or doctor what the current research 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, but medicinal doses don't have strong safety data behind them, and the essential oil can be irritating. Buchu should be avoided during pregnancy because it's traditionally thought to affect the uterus.

There isn't enough safety information to use it while breastfeeding, so skip it if you're nursing.

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 this product, check it against any blood thinners or antiplatelet drugs you take (aspirin, warfarin, clopidogrel, enoxaparin, heparin, and others), any medication that can damage the liver (such as acarbose or amiodarone), and lithium. These are Moderate-severity interactions.

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 leaf extract may be worth a look if you're interested in its traditional diuretic use — but only after you've checked it against any blood thinners, liver-damaging drugs, or lithium you take. Pregnant or breastfeeding?

Don't use it. Talk to your pharmacist before starting, especially if you're on any regular medications.

Buchu Leaf Extract3 drug types · 481 drugs

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.

Full Spectrum Buchu Leaf Extract 100 mg by Swanson: Common Questions

Does Full Spectrum Buchu Leaf Extract 100 mg by Swanson interact with any medications?
Yes. Based on its ingredients, Full Spectrum Buchu Leaf Extract 100 mg 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?
Full Spectrum Buchu Leaf Extract 100 mg 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.
Can I take this if I'm pregnant or breastfeeding?
No — buchu should be avoided during pregnancy because it's traditionally thought to affect the uterus, and there isn't enough safety data to use it while breastfeeding. Talk to your doctor or pharmacist about safer options.
What does buchu leaf extract do?
Buchu is traditionally used for its diuretic properties — meaning it's thought to help your body shed water. We don't have effectiveness ratings on file for specific health claims, so ask your pharmacist what research supports its use for your goal.
Is the essential oil safe?
The essential oil from buchu can be irritating, and medicinal doses in general lack strong safety data. This product is a leaf extract, not the oil, but if you're using high doses, be aware that buchu does contain pulegone, a known liver toxin.
What are the inactive ingredients?
The capsule contains rice flour, gelatin, maltodextrin, and calcium palmitate — these are binders and fillers with no active role.
Can I take this with lithium?
Buchu may reduce how your body clears lithium, potentially raising your lithium level. If you take lithium, check with your pharmacist before starting — your dose might need adjustment.
