HelloPharmacist Scorecard of Skullcap Alcohol-Free by Herb 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.

From our pharmacy team — supplement deep dive

Generated from HelloPharmacist’s pharmacist-curated databases and editorial rules · Last generated Sep 10, 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 is a single-ingredient liquid: skullcap flowering aerial parts extract made from fresh, undried plant material. The inactive ingredients are glycerin and distilled water, which help preserve and deliver the extract.

Does it work?

Not established
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 established

The graded evidence we hold for these ingredients covers different conditions than the ones this product is marketed for, so there's no established rating for its stated use — see Skullcap's own graded uses on its monograph.

Why this rating?
  • The label markets this product for: restore and tone nervous system.
  • We looked for evidence on: Anxiety, Insomnia, Stress, nervous tension, muscle tension.
  • The closest evidence on file: Skullcap is rated "Insufficient Reliable Evidence To Rate" for Anxiety (Natural Medicines).
  • Also on file: Skullcap is rated "Insufficient Reliable Evidence To Rate" for Insomnia, Stress.

The evidence we hold for skullcap doesn't support its use for any of the conditions listed — epilepsy, stress, stroke, spasticity, contact dermatitis, and premenstrual dysphoric disorder all have insufficient reliable evidence behind them. That doesn't mean it doesn't work; it means the research to prove it hasn't been done or isn't strong enough yet.

The evidence, ingredient by ingredient Skullcap

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.

Skullcap is usually used only short-term, but the safety data is limited and product quality can vary, so use it carefully. The most common side effects reported are cognitive impairment, digestive disturbances, and sedation.

A small number of trial participants taking higher doses (200 mg or more) experienced sedation and trouble thinking; one person taking a much larger dose reported vivid dreams. Mild digestive upset occurred in around 9% of participants in one trial.

The safety data advises against using skullcap during pregnancy. Safety while breastfeeding is unknown, so it's best to avoid it then as well.

If you're pregnant, planning pregnancy, or breastfeeding, talk with your doctor or pharmacist about whether this product is right for you.

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 — Skullcap.
  • The most serious interaction on file is rated Moderate.
  • For scale: 248 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 you take Skullcap Alcohol-Free, double-check all CNS depressants with your doctor or pharmacist — that includes sleeping pills, sedatives, anti-anxiety medications, some pain relievers, and antihistamines used for sleep or allergies. Skullcap can make these drugs work more strongly, leaving you more sedated or cognitively impaired than expected.

The bottom line

Scorecard at a glanceFully disclosed formula with no established evidence rating for its marketed use. Moderate medication interactions have been identified, and safety information is well characterized.

Skullcap may appeal to you if you're looking for a traditional herbal option for stress or sleep, but the evidence doesn't yet show it works for any condition listed here. The main risk is adding to the effects of sedative medications and making you drowsy or foggy.

Before you take it, especially if you're on any prescription or over-the-counter drugs, run them through our search tool and talk with your doctor or pharmacist about whether it's safe for your situation.
