HelloPharmacist Scorecard of Zi Su Zi 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.

This product contains one active ingredient: Perilla frutescens Fruit Extract (dry form). Perilla is a plant used in traditional medicine and cooking across Asia.

The liquid formulation also includes alcohol, water, and glycerin as inactive ingredients to deliver the extract.

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 Perilla product and its label doesn't state a use — see Perilla'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 we hold doesn't establish how well perilla works for any of the conditions it's used for — age-related cognitive decline, hay fever, asthma, osteoporosis, cancer, or headache all carry ratings of insufficient reliable evidence. That means the science isn't settled yet on whether it delivers a real benefit for these uses.

The evidence, ingredient by ingredient Perilla

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.

Perilla is generally well tolerated when used as a food, but supplement-strength products haven't been well studied. The main concern is a rare but serious allergic reaction called anaphylaxis, which has been reported in both adults and children who consumed perilla seeds — some research points to a component called oleosin as the trigger.

Topically, dermatitis (skin irritation) is the most common side effect reported. Because safety data during pregnancy and breastfeeding is limited, the guidance is to avoid medicinal amounts of perilla in both cases.

No known interactions
Known Interaction Concern · database check
No known interactions

No medication interactions are currently documented for the matched ingredients — that isn't a guarantee none exist.

Why this rating?
  • None of the 1 matched ingredient has a documented medication interaction on file.

No interactions are documented in our data for the ingredients we could check. That said, it's always smart to verify with your pharmacist before adding any new supplement to your routine.

The bottom line

Scorecard at a glanceFully disclosed formula with no assessable stated purpose. No medication interactions are currently documented, and safety information is well characterized.

Zi Su Zi may appeal to you if you're interested in traditional herbal remedies, but know that we don't have strong evidence it works for the conditions it's marketed for. If you have a history of allergies or asthma, talk to your pharmacist before trying it.

Pregnant or breastfeeding? Check with your doctor first — there isn't enough safety data to say it's okay.

Zi Su Zi by Hawaii Pharm: Common Questions

Does Zi Su Zi by Hawaii Pharm interact with any medications?
We do not currently list a known interaction for the mapped ingredients in Zi Su Zi. This does not guarantee none exist, so confirm with your pharmacist.
How can one product interact with so many drugs?
Zi Su Zi 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.
Is perilla safe to take if I have allergies or asthma?
Be cautious. Anaphylaxis — a serious allergic reaction — has been reported in people who consumed perilla seeds, and occupational asthma has been reported from inhaling smoke from roasted seeds. If you have a known allergy or asthma, talk to your pharmacist before using this product.
Can I take this while I'm pregnant or breastfeeding?
The safety data isn't there yet. The guidance is to avoid medicinal amounts of perilla during pregnancy and while breastfeeding. Talk with your doctor or pharmacist about what's right for your situation.
Does perilla actually work for hay fever, asthma, or brain fog?
We don't have reliable evidence yet that it works for any of those — or for osteoporosis, cancer, or headache either. The science just isn't settled, so we can't say whether it delivers a real benefit.
What are the side effects I should watch for?
When taken by mouth, perilla is generally well tolerated, though anaphylaxis (a rare serious allergic reaction) has been reported. If applied to skin, dermatitis (irritation) is the most common side effect. Stop and call your doctor if you notice any signs of an allergic reaction.
What exactly is perilla?
Perilla is a plant used in traditional Asian medicine and cooking. This product is made from an extract of its fruit in liquid form.
