HelloPharmacist Scorecard of Quassia by Herbalist & Alchemist
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
This product contains one active ingredient: dried quassia wood extract. Quassia comes from the heartwood of tropical trees and has been used traditionally in herbal medicine.
The extract is suspended in a liquid base made with distilled water and ethyl alcohol.
Does it work?
No specific claim
The evidence we hold doesn't establish whether quassia works for seborrheic dermatitis, lice, rosacea, or other conditions — the data shows insufficient reliable evidence for any of these uses. That doesn't mean it's ineffective; it means the research we have access to isn't strong enough yet to say one way or the other.
How safe is it?
Well-documented data
Taken by mouth in medicinal amounts, quassia can irritate your mouth and throat lining and cause nausea and vomiting. Long-term use raises a more serious concern: it's been linked to vision changes and even blindness.
The safety data advises against use during pregnancy and while breastfeeding because we don't have enough information to know it's safe in those situations. Applied to the skin, quassia appears generally well tolerated with no reported adverse effects.
Meds to double-check
Moderate interaction found
Before taking Herbalist & Alchemist's Quassia, double-check with your doctor or pharmacist if you take antidiabetes drugs, diuretics, digoxin (Lanoxin), H2-blockers, antacids, or proton pump inhibitors (PPIs). Quassia may lower blood sugar, compound potassium loss, affect heart medication levels, and reduce the effectiveness of acid-reducing drugs.
The bottom line
Scorecard at a glanceFully disclosed formula marketed for general wellness rather than one specific gradeable purpose. Moderate medication interactions have been identified, and safety information is well characterized.
Quassia is best used under the guidance of someone who knows your full medication list — especially if you take diabetes drugs, diuretics, heart medications, or acid-reducing drugs. The risk of digestive upset and the theoretical link to vision problems with long-term use mean it's not a casual-use herb.
Talk with your doctor or pharmacist before starting, particularly if you're pregnant, breastfeeding, or managing a chronic condition.

Quassia by Herbalist & Alchemist Drug Interactions
HelloPharmacist Interaction Report
Herbalist & Alchemist's Quassia does interact with several medication types.
The most serious concern is with antidiabetes drugs — quassia extract may lower blood sugar in a way that adds to what your diabetes medication already does, raising the risk of low blood sugar (hypoglycemia). You'll want to watch your glucose levels closely if you're on insulin or drugs like glimepiride (Amaryl) or glyburide (DiaBeta).
Read the full breakdown — every affected drug type, severity by severity
Quassia also carries Moderate interactions with diuretics (water pills) and digoxin (Lanoxin, a heart medication). Diuretics can already lower potassium, and quassia may make that worse — you might need extra potassium supplementation.
With digoxin, there's a theoretical risk that quassia could boost both the drug's desired and unwanted effects.
Minor interactions exist with acid-reducing medications: H2-blockers like famotidine (Pepcid) and ranitidine (Zantac), antacids, and proton pump inhibitors (PPIs) like omeprazole (Prilosec). Because quassia may increase stomach acid, it could reduce how well these medications work.
Altogether, these interactions span 198 individual medications. Before you start quassia, check your exact prescriptions with the search tool on this page or confirm with your doctor or pharmacist.

dried Quassia wood extract
Antidiabetes Drugs
In animals, quassia extract reduced levels of fasting glucose. Theoretically, quassia might have additive effects when used with antidiabetes drugs. This might increase the risk of hypoglycemia in some patients. Monitor blood glucose levels closely.
Some antidiabetes drugs include glimepiride (Amaryl), glyburide (DiaBeta, Glynase PresTab, Micronase), insulin, metformin (Glucophage), pioglitazone (Actos), rosiglitazone (Avandia), and others.
Digoxin (Lanoxin)
Theoretically, concomitant use with cardiac medications might increase the risk of therapeutic and adverse effects.
Diuretic Drugs
Overuse of quassia might compound diuretic-induced potassium loss. There is some concern that people taking quassia along with potassium depleting diuretics might have an increased risk for hypokalemia. Initiation of potassium supplementation or an increase in potassium supplement dose may be necessary for some patients.
Some diuretics that can deplete potassium include chlorothiazide (Diuril), chlorthalidone (Thalitone), furosemide (Lasix), and hydrochlorothiazide (HCTZ, Hydrodiuril, Microzide), and others.
Antacids
Theoretically, due to reports that quassia increases stomach acid, quassia might decrease the effectiveness of antacids.
H2-Blockers
Theoretically, due to reports that quassia increases stomach acid, quassia might decrease the effectiveness of H2-blockers. The H2 blockers include cimetidine (Tagamet), ranitidine (Zantac), nizatidine (Axid), and famotidine (Pepcid).
Proton Pump Inhibitors (Ppis)
Theoretically, due to reports that quassia increases stomach acid, quassia might decrease the effectiveness of PPIs. PPIs include omeprazole (Prilosec), lansoprazole (Prevacid), rabeprazole (Aciphex), pantoprazole (Protonix), and esomeprazole (Nexium).
