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

Low disclosure
Ingredient Transparency · database check
Low

Most active ingredients don't disclose an individual amount — you can't tell how much of each you're getting.

Why this rating?
  • The label discloses an exact amount for 0 of its 1 active ingredient.

This product contains one active ingredient: an infusion of Cytisus scoparius (scotch broom flower) at a ratio of 1 part plant to 6,000 parts liquid. The liquid base includes water and brandy.

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 Scotch Broom product and its label doesn't state a use — see Scotch Broom'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 data in our records for scotch broom flower essence.

The evidence, ingredient by ingredient Scotch Broom

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.

Scotch broom is considered unsafe for most people. It contains toxic alkaloids that can affect the heart and nervous system.

At doses above 300 mg of sparteine — roughly 30 grams of raw scotch broom — toxicity can occur with symptoms including dizziness, headache, heart palpitations (irregular or racing heartbeat), tingling in the arms and legs, weakness, sweating, sleepiness, dilated pupils, and eye muscle paralysis. Nausea, diarrhea, and vertigo are also reported.

The safety data advises against use during pregnancy — it may stimulate the uterus — and during breastfeeding, given the toxic alkaloids present.

Side effects, ingredient by ingredient Scotch Broom

Major interaction found
Known Interaction Concern · database check
Major identified

At least one ingredient has a documented Major-severity interaction. Check your medications for a personalized result.

Why this rating?
  • 1 of the 1 matched ingredient can interact with medications — Scotch Broom.
  • The most serious interaction on file is rated Major.
  • Some involve high-stakes drug classes: lithium.
  • For scale: 12 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 with your pharmacist if you use heart rhythm medications (quinidine), antipsychotics (haloperidol), older antidepressants called MAOIs, or lithium. These carry Major or Moderate interaction risks.

The bottom line

Scorecard at a glanceFormula with limited ingredient disclosure with no assessable stated purpose. Major medication interactions have been identified, and safety information is well characterized.

Given the toxicity risks and serious medication interactions, this product warrants a careful conversation with your pharmacist, especially if you're on any heart, psychiatric, or mood-stabilizing medications. Most people should avoid it altogether.

infusion (1:6000) of Cytisus scoparius4 drug types · 12 drugs

Haloperidol (Haldol)

Haloperidol (Haldol) inhibits sparteine metabolism, increasing the risk of adverse effects including circulatory collapse.

Likelihood Probable Evidence D
Monoamine Oxidase Inhibitors (Maois)

Scotch broom flower contains tyramine. Combined use with MAOIs might cause a hypertensive crisis.

Likelihood Probable Evidence D
Quinidine

Quinidine (Quinidex) inhibits the metabolism of sparteine, a constituent of Scotch broom. This might increase levels of sparteine and increase the risk of adverse effects, including circulatory collapse.

Likelihood Probable Evidence D
Lithium

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