HelloPharmacist Scorecard of Quassia by Hawaii Pharm
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: Quassia Bark Extract, Dry. Quassia has a long history of use in traditional medicine for skin conditions and parasites, though modern evidence for its effectiveness is limited.
The liquid also includes alcohol, water, and glycerin as inactive ingredients to preserve and deliver the extract.
Does it work?
Couldn't assess
The evidence for quassia is not well established in our data. It's been studied for seborrheic dermatitis (a flaky, itchy scalp condition), lice, and rosacea (facial redness and bumps), but we hold insufficient reliable evidence to rate how well it works for any of these uses.
If you're considering it for one of these conditions, talk with your doctor or pharmacist about whether the current evidence supports a trial and what alternatives might be better studied.
How safe is it?
Well-documented data
Taken by mouth, quassia can irritate the mouth, throat, and digestive lining and may cause nausea and vomiting when used in medicinal amounts. Long-term use has been reported to cause vision changes and even blindness.
The safety data advises against use during pregnancy and while breastfeeding because of traditional concerns and lack of safety testing. Applied to the skin, quassia appears well tolerated with no reported adverse effects.
Meds to double-check
Moderate interaction found
Before taking Quassia, check with your doctor or pharmacist if you take antidiabetes drugs, diuretics (water pills), digoxin (Lanoxin), H2-blockers, antacids, or proton pump inhibitors (PPIs) — quassia may change how these work or raise the risk of side effects. The highest-priority concern is with diabetes and heart medications.
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.
Quassia may be worth considering if you're exploring traditional remedies for skin or parasitic concerns, but the evidence for it is thin and it carries real risks — especially if you take diabetes medication, diuretics, digoxin, or stomach acid–reducing drugs. Talk with your doctor or pharmacist before starting, particularly if you're pregnant, breastfeeding, or take any prescription medications.

Quassia by Hawaii Pharm Drug Interactions
HelloPharmacist Interaction Report
Quassia by Hawaii Pharm has documented interactions with several medication types.
The most serious concern is with antidiabetes drugs — quassia extract may lower blood glucose (blood sugar) in ways that add to what your diabetes medication already does, raising the risk of low blood sugar (hypoglycemia). If you take drugs like glimepiride or glyburide, you'll need to watch your blood glucose closely.
Read the full breakdown — every affected drug type, severity by severity
Quassia can also interact with diuretics (water pills), especially the kind that lower potassium levels — it may compound that potassium loss and raise the risk of dangerously low potassium (hypokalemia). It may also affect digoxin (Lanoxin), a heart medication, by increasing both its therapeutic and adverse effects.
You should check with your doctor or pharmacist before combining quassia with any of these.
Minor interactions are documented with stomach acid–reducing drugs: H2-blockers like cimetidine and famotidine, antacids, and proton pump inhibitors (PPIs) like omeprazole and lansoprazole. Because quassia may increase stomach acid, it might make these medications less effective.
Altogether, these interactions span 198 individual medications. Check your exact drugs against the tool below before starting.

For each ingredient in Quassia with known interactions, here are the types of medications it can affect. Open any type for the detail — or search your exact drug in the checker above.
Quassia Bark Extract, Dry
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).
