HelloPharmacist Scorecard of Qing Hao 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.

From our pharmacy team — supplement deep dive

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.

Qing Hao contains one active ingredient: Artemisia annua herb extract, commonly called Sweet Annie. The liquid also includes alcohol, water, and glycerin as inactive ingredients to deliver the extract.

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

This product doesn't appear to be marketed for a specific use, so we graded Sweet Annie's overall clinical evidence instead.

Moderate

Some clinical evidence supports Sweet Annie for:

Why this rating?
  • We looked at the product name, claims, and label statements and couldn't find a stated purpose to grade.
  • Since the label doesn't commit to one use, we graded the ingredient's overall clinical evidence instead.
  • On file: Allergic rhinitis (hay fever) — rated "Possibly Effective" (Natural Medicines).

Sweet Annie has possibly effective evidence for allergic rhinitis (hay fever) — meaning some clinical support exists, but the evidence isn't yet strong or complete. For nonalcoholic fatty liver disease (NAFLD), malaria, and osteoarthritis, the evidence we hold is insufficient to establish whether it works.

Talk with your doctor about whether Qing Hao is the right choice for what you're treating.

The evidence, ingredient by ingredient Sweet Annie

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.

When taken by mouth, Sweet Annie is generally well tolerated, though nausea and vomiting are the most common side effects. Rare cases of liver damage (hepatotoxicity) have been reported — in one documented case, a person developed hepatitis after ten days of high-dose use, though symptoms improved after stopping.

Sweet Annie should not be used during pregnancy because of possible harm to the developing baby. There isn't enough safety information to use it while breastfeeding, so avoid it during lactation.

A mild allergic reaction (rash and cough) has been reported in one case. If you experience numbness of the tongue or throat itching, discontinue use.

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 — Sweet Annie.
  • The most serious interaction on file is rated Moderate.
  • For scale: 890 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 Qing Hao, check with your pharmacist or doctor if you take any drugs toxic to the liver or medications processed through the CYP3A4 and CYP2B6 liver pathways (both Moderate severity interactions). Because the research on how Sweet Annie affects these pathways is mixed, your doses may need adjusting or monitoring.

The bottom line

Scorecard at a glanceFully disclosed formula with some supporting evidence behind its ingredients' uses. Moderate medication interactions have been identified, and safety information is well characterized.

Qing Hao may help with hay fever symptoms, though the evidence is preliminary. Because Sweet Annie can affect how your liver processes many medications and carries a theoretical risk of liver toxicity, anyone taking prescription drugs — especially those affecting the liver or metabolized through liver pathways — should check with their doctor or pharmacist before starting.

Avoid during pregnancy and breastfeeding.

Artemisia annua Herb Extract, Dry3 drug types · 889 drugs

Cytochrome P450 2B6 (Cyp2B6) Substrates

Sweet Annie may alter plasma levels and clinical effects of drugs metabolized by CYP2B6.
In vitro research shows that the Sweet Annie constituent artemisinin induces CYP2B6, possibly increasing CYP2B6 activity by 1.6-fold. However, Sweet Annie extract seems to inhibit the activity of CYP2B6 in vitro, suggesting that other constituents of Sweet Annie play a role in its effects on the overall activity of this enzyme. More information is needed to determine whether taking Sweet Annie extract affects the metabolism of CYP2B6 substrates.

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

Sweet Annie may alter plasma levels and clinical effects of drugs metabolized by CYP3A4.
In vitro research shows that the Sweet Annie constituent artemisinin induces CYP3A4, possibly increasing CYP3A4 activity by 1.9-fold. However, Sweet Annie extract seems to inhibit the activity of CYP3A4 in vitro, suggesting that other constituents of Sweet Annie play a role in its effects on the overall activity of this enzyme. More information is needed to determine whether taking Sweet Annie extract affects the metabolism of CYP3A4 substrates.

Likelihood Possible Evidence D
Hepatotoxic Drugs

Theoretically, concomitant use might have additive adverse hepatotoxic effects.
There is some concern that Sweet Annie can adversely affect the liver.

Qing Hao by Hawaii Pharm: Common Questions

Does Qing Hao by Hawaii Pharm interact with any medications?
Yes. Based on its ingredients, Qing Hao has a known interaction with 889 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Qing Hao 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.
Can I take Qing Hao while pregnant or breastfeeding?
No — the safety data advises against it during pregnancy because of possible harm to the developing baby, and there isn't enough information to use it safely while breastfeeding. Talk with your doctor or pharmacist about whether it's right for you.
What are the most common side effects?
Nausea and vomiting are the most common side effects when taken by mouth. Sweet Annie is generally well tolerated overall, though rare cases of liver damage have been reported.
Does Qing Hao really work for hay fever?
Sweet Annie has possibly effective evidence for allergic rhinitis (hay fever), meaning some clinical support exists but the evidence isn't yet strong or complete. It may help, but talk with your doctor about whether it's the best option for you.
Why do I need to check my medications before starting this?
Sweet Annie can change how your liver processes many common drugs, either speeding up or slowing down their effects — which could make them less or more powerful than intended. It also carries a theoretical risk of adding to liver damage if you're on drugs that can harm the liver.
How long can I safely take Qing Hao?
Sweet Annie is generally used short-term. Quality and dose vary widely between products, and it should not replace proven treatments. Talk with your doctor about how long it's safe for you to use it.
