There is not enough independent feedback here to call those themes reliable. Low review confidence — the 4.8 from 94 to 98 ratings sits in a review widget on the brand’s own site (15 of the 31 reviews in the page were flagged as verified buyers, and the brand launched in 2025), Amazon shows 4.2 from 30 ratings with the review text behind a sign-in, and no Trustpilot or Better Business Bureau profile was found.
Why it might work
The brand describes the formula in Chinese medicine terms: Inula flower to direct digestion downward, hematite to anchor rising stomach energy, and licorice to harmonize and soothe, plus isomaltooligosaccharide as a sweet prebiotic fiber. In conventional terms, none of the three herbs has a trial of its own in reflux, so how any of them would act on heartburn is not established; the classical seven-herb decoction they come from has one small open-label trial against a PPI. Licorice’s glycyrrhizin is known to raise sodium and lower potassium and raise blood pressure in some people at higher or long-term intakes. Hematite is an iron-oxide mineral that Chinese pharmacy texts record as toxic in large doses or with long use. The label does not say how much of any herb a spoonful holds, so the dose of each cannot be checked from it.
What the research supports
No trial of this product was found. The nearest human evidence is a 2025 single-center, open-label trial in China of the seven-herb classical formula Xuanfu Daizhe Tang against the proton-pump inhibitor rabeprazole in 72 people for eight weeks, where the reflux questionnaire score ended at 7.91 against 11.75 (63 analyzed, one against eight dropouts). This label contains three of those seven herbs as a syrup with no per-herb amounts, and systematic reviews of Chinese herbal formulas for reflux describe small, low-quality trials. The brand itself states that the studies tested the traditional formula as a prescribed decoction, not this product.
What the label discloses
Inula flower, licorice root and hematite are listed as a proprietary 10:1 extract blend with no amount for any herb; the brand states about 20 g of raw-herb equivalent per 2 ml serving across all three. The brand states third-party testing for purity, potency, heavy metals and microbiology and a cGMP facility, but no certificate, laboratory or manufacturer was found. The licorice is whole root rather than DGL, so it contains glycyrrhizin, and the glycyrrhizin content is not stated.
Who this tends to suit
We match this product to people reporting heartburn or reflux and symptoms that follow particular foods. It fits someone whose priority is day-to-day comfort or handling meals. Whether it is the best fit for you depends on the rest of your answers — what you have already tried, what format you will take, and anything that has to be ruled out.
Where it may not fit
The label supports gluten-free, dairy-free and vegan. We flag this product for anyone pregnant or breastfeeding or taking prescription medication, and the quiz removes it rather than recommending it in those cases. That is a caution about who should be deciding, not a claim about the product. A liquid only works if you will take it as often as the label directs.
Side effects and what to be aware of
The brand-site reviews are almost all positive, with occasional reports of no clear effect or of a very thick liquid that sticks to the lid. The brand lists mild nausea at the start, and its page says to talk to a doctor first if pregnant or breastfeeding, taking diuretics, corticosteroids or heart medication, or with high blood pressure or a heart or kidney condition, because of the licorice. The Amazon listing says to consult a physician if pregnant, nursing, taking medication or with a medical condition. The three-bottle subscription is the option preselected on the brand’s page.
Common questions
Does Liáo Reflux Relief work?
No trial of Liáo itself was found. The brand cites a 2025 trial of the seven-herb classical formula Xuanfu Daizhe Tang against rabeprazole (72 people, eight weeks, reflux questionnaire 7.91 against 11.75), but that trial was open-label, grouped patients by order of visit and lost one against eight participants, and Liáo keeps three of the seven herbs. Reviews on the brand’s own site average 4.8 from 94 ratings and Amazon shows 4.2 from 30; some reviewers report relief within weeks and a few report no clear effect.
Is Liáo safe, and what are its side effects?
The brand says a small number of customers notice mild nausea at first. The licorice in it is whole root, which contains glycyrrhizin and can raise blood pressure and lower potassium in some people, and the brand tells people with high blood pressure, heart or kidney conditions, or taking diuretics, corticosteroids or heart medication to ask a doctor first. Hematite is a mineral that Chinese pharmacy texts record as toxic with large doses or long use; the amount in Liáo is not printed.
Can I take Liáo with omeprazole or another PPI?
Liáo is sold as a supplement, not a medicine, and the brand says it is not a replacement for prescribed medication and to leave 30 to 60 minutes between Liáo and medication. In the one trial the brand cites, the comparison was the full seven-herb decoction against rabeprazole, not Liáo. No study of Liáo taken with a PPI was found, and licorice has reported interactions with diuretics, digoxin, corticosteroids, warfarin and cyclosporine.
How much does Liáo cost?
One 120 ml bottle is $49.00 one time, which is $1.63 a day at two 2 ml spoonfuls a day, plus $5 shipping on orders under $55. The three-bottle subscription is $110.25 every 90 days ($1.23 a day) and is the option selected when the page loads; one bottle on subscription is $41.65. Amazon lists $49.00, or $41.65 on Subscribe & Save.
Who makes Liáo, and what is the refund policy?
Liao Herbal LLC is based in San Diego, founded in 2025, and led by Dr. Lyda Kermani, a Doctor of Acupuncture and Chinese Medicine according to the brand. The brand offers a 30-day money-back guarantee, but the buyer requests the return first and pays return shipping, and sale items are not returnable. No Trustpilot or Better Business Bureau profile was found, so there is no independent record of billing or refund complaints either way.
