HelloPharmacist Scorecard of Scullcap (Certified Organic) Powder by TerraVita Premium Collection

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
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: skullcap powder, a dried herb used traditionally to support calm and relaxation. The powder form means you're getting the whole plant material without added binders or fillers — there are no inactive ingredients listed for this product.

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 Skullcap product and its label doesn't state a use — see Skullcap'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.

The evidence for skullcap's effectiveness is not established in the data we hold. Studies rate its use for epilepsy, stress, stroke, spasticity, contact dermatitis, and premenstrual dysphoric disorder (severe menstrual mood changes) all as insufficient — meaning there isn't reliable research yet to say whether it works for these purposes.

If you're considering it for a specific health goal, that's worth discussing with your doctor or pharmacist, since the science doesn't yet support a clear benefit.

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 generally well tolerated, but the safety picture is incomplete. The most common side effects reported with regular use are sedation, cognitive impairment (trouble concentrating or thinking clearly), and digestive disturbances — with mild stomach upset occurring in about 9% of people taking a standard dose for 2 weeks.

Because evidence is limited and product quality can vary, use it with care and stick to short-term use unless advised otherwise by your healthcare provider. The safety data advises against skullcap during pregnancy and while breastfeeding, so if you're pregnant, planning to become pregnant, or nursing, talk with your doctor or pharmacist before taking it.

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 taking this product, check with your doctor or pharmacist if you're on any CNS depressants — that includes sedatives and sleep aids, anti-anxiety medications, muscle relaxants, and certain pain relievers. Skullcap can add to their drowsiness and mental fog (Moderate severity).

If you're unsure whether your medications are in that category, use the search tool on this page to look them up.

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.

Skullcap is a traditional calming herb, but we don't yet have solid evidence it works for the conditions it's used for. The bigger concern is that it can add to the drowsiness of sedatives, sleep aids, anxiety drugs, and certain pain relievers — a Moderate interaction.

If you're on any medication that makes you drowsy or affects focus, check with your own doctor or pharmacist before starting this product. It's also not advised during pregnancy or breastfeeding.

Scullcap (Certified Organic) Powder by TerraVita Premium Collection: Common Questions

Does Scullcap (Certified Organic) Powder by TerraVita Premium Collection interact with any medications?
Yes. Based on its ingredients, Scullcap (Certified Organic) Powder has a known interaction with 248 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Scullcap (Certified Organic) Powder 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.
What does skullcap actually do?
Skullcap has been used traditionally to promote calm and relaxation, but we don't yet have reliable research showing it works for epilepsy, stress, stroke, spasticity, skin reactions, or menstrual mood problems. The science just isn't there to say one way or the other.
Will this make me drowsy?
Yes — sedation is one of the most common side effects reported with skullcap, especially at higher doses. Animal and clinical research suggests it can cause drowsiness and trouble thinking clearly. If you're already taking a medication that makes you drowsy, the two together could amplify that effect.
Is it safe to take during pregnancy or while breastfeeding?
No — there isn't enough safety data, so skullcap is best avoided if you're pregnant or nursing. Talk with your doctor or pharmacist about whether this product is right for you if you're in either situation.
What are the side effects I might notice?
The most common ones are sedation, trouble concentrating or thinking clearly, and digestive upset. Mild stomach disturbances were reported in about 9% of people taking it for 2 weeks. One person reported vivid dreams on a higher dose, but it's unclear if skullcap was the cause.
How long can I take this safely?
Skullcap is often used short-term, and the safety data is limited. Because product quality can vary, it's smart to use it with care and stick to short-term use unless your doctor or pharmacist advises otherwise.
Can I take this with sleep aids or anxiety medications?
Not without checking first — skullcap can have additive effects (Moderate severity) with sedatives, sleep aids, anti-anxiety drugs, and other CNS depressants, meaning both could make you drowsier or more mentally fogged than intended. Talk with your own doctor or pharmacist before combining them.
