HelloPharmacist Scorecard of Hempanol-CF by North American Herb & Spice

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

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 2 active ingredients.
  • “Proprietary Blend” is a proprietary blend — the label gives one combined amount (460 mg) without saying how much of each component you get.

Hempanol-CF contains two active ingredients: wild rosemary oil and a proprietary blend that includes raw, CO2 extract from high beta-caryophyllene and phytoterpene hemp stalk extract. The product has no inactive ingredients listed.

Does it work?

Moderate evidence
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
Moderate

Some clinical evidence supports this product's ingredients for its stated purpose, but it isn't conclusive.

Why this rating?
  • The label markets this product for: calm focus and nervous system support.
  • We looked for evidence on: Stress, Mental alertness, Memory, Anxiety, Cognitive function.
  • The strongest evidence on file: Rosemary is rated "Possibly Effective" for Memory (Natural Medicines).
  • Also on file: Rosemary is rated "Insufficient Reliable Evidence To Rate" for Mental alertness, Stress.

The rosemary oil in this product is possibly effective for memory, according to the evidence we hold. For other uses—age-related cognitive decline, hair loss (alopecia areata), and fatty liver disease—the evidence is insufficient to rate whether it works.

The hemp extract's effectiveness for constipation, eczema, or cholesterol problems is also insufficient to rate in our data.

The evidence, ingredient by ingredient Rosemary Hemp

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 2 of the 2 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 2 of 2.
  • General safety write-ups exist for 2 of 2.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Rosemary oil is safe in normal food amounts, but concentrated extracts and undiluted essential oil need caution. The product may cause allergic reactions when applied to skin, swelling of the lips and gums when used in the mouth, and rarely, occupational asthma if inhaled.

Undiluted rosemary oil might trigger seizures. Hemp products are generally well tolerated in food amounts, but concentrated extracts are less studied.

Rare cases of allergic reactions—including hives, facial swelling, and anaphylaxis—have been reported, and one case of liver inflammation occurred in a young child given high doses of hemp extract. For pregnancy, rosemary is rated possibly unsafe; food amounts are likely fine, but medicinal doses should be avoided.

There is not enough safety data on medicinal-dose hemp during lactation to know either way.

Side effects, ingredient by ingredient Rosemary Hemp

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?
  • 2 of the 2 matched ingredients can interact with medications — Rosemary, Hemp.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; diabetes medications.
  • For scale: 1,023 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.

Check before combining this product with blood thinners or antiplatelet drugs (moderate-severity risk of bleeding), diabetes medications (moderate-severity risk of low blood sugar), aspirin and salicylate-containing pain relievers (moderate-severity additive effects), hormone therapy (moderate-severity), blood pressure medications and ACE inhibitors (minor-severity), and any drugs your liver metabolizes quickly, especially through the CYP1A2 and CYP3A4 pathways (minor-severity). Your pharmacist can confirm whether your specific medications are affected.

The bottom line

Scorecard at a glanceFormula with limited ingredient disclosure with some supporting evidence for its stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.

This product may be worth considering if you're interested in memory support and tolerate herbal supplements well. However, if you take blood thinners, diabetes medications, aspirin-type drugs, or blood pressure medications, talk with your doctor or pharmacist before starting—the interactions are real and may affect how your drugs work.

If you have a history of allergies to herbs or hemp, proceed cautiously and discuss it with your healthcare provider first.

raw, CO2 extract from high beta Caryophyllene & phytoterpene hemp stalk extract6 drug types · 938 drugs

Estrogens

Theoretically, hemp might interfere with hormone therapy due to its estrogenic effects.
In an ovariectomized animal model, a diet containing hemp seed 1%, 2%, or 10% resulted in normalized plasma levels of 17-beta-estradiol. The mechanism of action for this effect is unclear.

Likelihood Possible Evidence D
Ace Inhibitors (Aceis)

Theoretically, consuming hemp seed protein isolate with ACE inhibitors might have additive effects and increase the risk of hypotension.
Hemp seed protein hydrolysate has shown ACE inhibitor-like effects in a hypertensive animal model. However, hempseed oil consumption does not seem to reduce blood pressure in humans. Until more is known, monitor blood pressure and potassium levels.

Likelihood Unlikely Evidence D
Anticoagulant/Antiplatelet Drugs

Theoretically, hemp seed might increase the risk of bleeding when used concomitantly with anticoagulant/antiplatelet drugs.
In animal research, hemp seed at 5% of the diet inhibits platelet aggregation in vitro. However, in human research, taking hemp seed oil 2 grams daily for 12 weeks does not inhibit the aggregation of platelets in vitro.

Likelihood Possible Evidence D
Antihypertensive Drugs

Theoretically, hemp seed protein may have additive effects with antihypertensive drugs.
In a hypertensive animal model, hemp seed protein hydrolysate reduced systolic blood pressure by a mechanism possibly involving the inhibition of renin and angiotensin converting enzyme (ACE) activities. However, there was no effect of hemp seed protein on blood pressure in normotensive animals. Furthermore, hempseed oil consumption does not seem to reduce blood pressure in humans.

Likelihood Unlikely Evidence D
Cytochrome P450 1A2 (Cyp1A2) Substrates

Theoretically, hemp might decrease the levels and clinical effects of CYP1A2 substrates.
In vitro research shows that hemp induces CYP1A2 enzymes.

Likelihood Possible Evidence D
Cytochrome P450 3A4 (Cyp3A4) Substrates

Theoretically, hemp might decrease the levels and clinical effects of CYP3A4 substrates.
In vitro research shows that hemp induces CYP3A4 enzymes.

Likelihood Possible Evidence D

wild Rosemary Oil6 drug types · 372 drugs

Anticoagulant/Antiplatelet Drugs

Theoretically, rosemary may increase the risk of bleeding if used with anticoagulant or antiplatelet drugs.
In vitro and animal research suggests that rosemary inhibits platelet aggregation.

Likelihood Possible Evidence D
Antidiabetes Drugs

Theoretically, taking rosemary with antidiabetes drugs might increase the risk of hypoglycemia.
Animal research shows that rosemary extract can decrease blood glucose levels in diabetic models. However, research in humans is conflicting. Although rosemary powder decreased blood glucose levels in healthy adults, no change in blood glucose levels was seen in adults with type 2 diabetes, most of whom were taking antidiabetes drugs.

Likelihood Possible Evidence B
Aspirin

Theoretically, rosemary might have additive effects with salicylate-containing drugs such as aspirin.
Rosemary is reported to contain salicylates.

Likelihood Possible Evidence D
Choline Magnesium Trisalicylate (Trilisate)

Theoretically, rosemary might have additive effects with salicylate-containing drugs such as choline magnesium trisalicylate.
Rosemary is reported to contain salicylate.

Likelihood Possible Evidence D
Salsalate (Disalcid)

Theoretically, rosemary might have additive effects with salicylate-containing drugs such as salsalate.
Rosemary is reported to contain salicylate.

Likelihood Possible Evidence D
Cytochrome P450 1A2 (Cyp1A2) Substrates

Theoretically, rosemary might decrease the levels and clinical effects of CYP1A2 substrates.
In vitro research shows that rosemary induces CYP1A2 enzymes. This effect has not been reported in humans.

Hempanol-CF by North American Herb & Spice: Common Questions

Does Hempanol-CF by North American Herb & Spice interact with any medications?
Yes. Based on its ingredients, Hempanol-CF has a known interaction with 1,022 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Hempanol-CF contains 2 active ingredients, and an interaction can come from any of them. We check every ingredient, combine the results into one list per medication, and show which ingredient and mechanism is 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 the rosemary oil in this product actually do?
Rosemary oil is possibly effective for memory support based on the evidence we hold. For other conditions like age-related cognitive decline or hair loss, we don't have enough evidence to say whether it works.
Is this safe if I have a history of allergies?
Both rosemary and hemp can trigger allergic reactions—rosemary may cause skin rashes and swelling of the lips or gums, while hemp has rare reports of hives, facial swelling, and anaphylaxis. If you have a history of herb or food allergies, talk with your doctor or pharmacist before trying this product.
Can I take this while pregnant?
Rosemary is rated possibly unsafe during pregnancy; food amounts are likely okay, but medicinal doses should be avoided. For hemp, there isn't enough safety data on medicinal doses to know either way. Talk with your doctor or pharmacist about whether this product is right for you during pregnancy.
Can rosemary oil cause seizures?
Yes—undiluted rosemary oil and its camphor component might trigger seizures in some people. This product is a concentrated extract, so this risk applies.
What's the difference between food amounts and the amounts in this supplement?
Rosemary and hemp are safe in normal cooking or food amounts, but concentrated extracts and supplements are more potent and less well studied. This product is a concentrated extract, which is why caution is advised and why you should check for drug interactions.
