HelloPharmacist Scorecard of Myomin by Chi

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

Generated from HelloPharmacist’s pharmacist-curated databases and editorial rules · Last generated Jul 11, 2026

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 3 active ingredients.
  • “Proprietary Herbal Extract Blend” is a proprietary blend — the label gives one combined amount (1,000 mg) without saying how much of each component you get.

Myomin contains 3 active herbal ingredients. Two of them are extracts: astragalus (Astragalus membranaceus), used traditionally to support immune function, and zedoary (Curcuma zedoaria), a ginger-family plant.

The third is Cyperus rotundus extract. The product also contains a proprietary herbal blend, meaning some ingredients are part of a combined formula whose exact composition isn't disclosed on the label.

There are no inactive fillers or binders listed.

Does it work?

Not established
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 established

The graded evidence we hold for these ingredients covers different conditions than the ones this product is marketed for, so there's no established rating for its stated use.

Why this rating?
  • The label markets this product for: All natural herbal supplement for general wellness.
  • We looked for evidence on: Chronic fatigue syndrome (CFS), Chemotherapy-related fatigue, Post-stroke fatigue, Upper respiratory tract infection (URTI), General immune support, Energy and vitality — and 1 related terms.
  • The closest evidence on file: Astragalus is rated "Insufficient Reliable Evidence To Rate" for Chemotherapy-related fatigue (Natural Medicines).
  • Also on file: Astragalus is rated "Insufficient Reliable Evidence To Rate" for Chronic fatigue syndrome (CFS), Upper respiratory tract infection (URTI), Post-stroke fatigue.

The effectiveness data we hold shows insufficient reliable evidence to rate astragalus for hay fever, amenorrhea, aplastic anemia, angina, asthma, beta-thalassemia, and other conditions. For zedoary, the evidence is similarly insufficient to rate it for rotaviral diarrhea and high cholesterol.

We have no effectiveness ratings on file for Cyperus rotundus extract.

The evidence, ingredient by ingredient Astragalus Zedoary Adrue

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 3 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 3 of 3.
  • General safety write-ups exist for 3 of 3.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Astragalus is generally well tolerated short-term in healthy adults, though human safety data is limited. The safety data advises against use during pregnancy and breastfeeding.

Reported side effects from astragalus are uncommon and include rare reports of dizziness and chest discomfort (angina), though these may not have been caused by the herb itself. Zedoary is generally used in food amounts, but human safety data for supplement doses is limited.

The safety data advises against it during pregnancy because it may affect the uterus, and breastfeeding is best avoided due to insufficient safety information. We hold no adverse effects data for zedoary or Cyperus rotundus extract.

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?
  • 3 of the 3 matched ingredients can interact with medications — Adrue, Zedoary, Astragalus.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: immunosuppressants / transplant drugs; diabetes medications; lithium.
  • For scale: 986 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 with your pharmacist if you take immunosuppressants or cyclophosphamide (drugs that suppress immune function or used in cancer treatment), lithium (a mood stabilizer), diabetes medications, or any drugs broken down by your liver's CYP3A4 pathway—especially certain cancer medications like lapatinib, sorafenib, or gefitinib.

The bottom line

Scorecard at a glanceFormula with limited ingredient disclosure with no established evidence rating for its marketed use. Moderate medication interactions have been identified, and safety information is well characterized.

If you take immune-suppressing medications, lithium, diabetes drugs, or certain cancer medications, check this product with your pharmacist before starting. The same goes if you're pregnant, breastfeeding, or planning to become pregnant.

It's a traditional herbal formula, but the evidence for its effectiveness isn't established in our data.

Curcuma zedoaria Extract1 drug type · 643 drugs

Cytochrome P450 3A4 (Cyp3A4) Substrates

Theoretically, zedoary might increase levels of drugs metabolized by CYP3A4.
In-vitro research shows that a methanol extract of zedoary strongly inhibits the CYP3A4 metabolism of the tyrosine kinase inhibitors lapatinib and sorafenib, and to a lesser extent, gefitinib.

Likelihood Possible Evidence D
Curcuma zedoaria Extract full monograph & interactions

Cyperus rotundus Extract3 drug types · 256 drugs

Barbiturates

Animal research suggests that taking adrue in combination with sodium thiopental increases total sleep time three-fold compared to the effects of sodium thiopental alone. Theoretically, concomitant use of adrue and barbiturates might increase the risk of drowsiness and motor reflex depression. Some barbiturates include amobarbital (Amytal), butabarbital (Butisol), mephobarbital (Mebaral), pentobarbital (Nembutal), phenobarbital (Luminal), secobarbital (Seconal), and others.

Likelihood Possible Evidence D
Benzodiazepines

Animal research suggests that taking adrue in combination with diazepam increases total sleep time four-fold compared to the effects of diazepam alone. Theoretically, concomitant use adrue and benzodiazepines might increase the risk of drowsiness and motor reflex depression. Some benzodiazepines include clonazepam (Klonopin), diazepam (Valium), lorazepam (Ativan), and others.

Likelihood Possible Evidence D
Cns Depressants

Animal research suggests that taking adrue in combination with sodium thiopental or diazepam increases total sleep time up to four-fold compared to the effects of the drugs alone. Theoretically, concomitant use of adrue with CNS depressants might cause additive sedation. Some CNS depressants include benzodiazepines, such as diazepam (Valium), alprazolam (Xanax), triazolam (Halcion), and estazolam (ProSom); barbiturates, such as mephobarbital (Mebaral), phenobarbital (Luminal Sodium), and pentobarbital sodium (Nembutal); zolpidem (Ambien); and others.

Astragalus membranaceus extract4 drug types · 208 drugs

Antidiabetes Drugs

Theoretically, taking astragalus with antidiabetes drugs might increase the risk of hypoglycemia.
Clinical research in humans shows that astragalus might have hypoglycemic effects. Theoretically, taking astragalus, especially in combination with other hypoglycemic agents, might increase the risk of hypoglycemia.

Likelihood Probable Evidence A
Cyclophosphamide

Theoretically, astragalus might interfere with cyclophosphamide therapy.
Evidence regarding the effect of astragalus on immunosuppression caused by cyclophosphamide is conflicting. Some animal research suggests that astragalus reverses cyclophosphamide-induced immunosuppression. However, other animal research shows no effect.

Likelihood Possible Evidence D
Immunosuppressants

Theoretically, astragalus might interfere with immunosuppressive therapy.
Astragalus seems to stimulate immune function. Theoretically, taking astragalus might decrease the effects of immunosuppressive therapy.

Likelihood Possible Evidence D
Lithium

Theoretically, astragalus might increase levels and adverse effects of lithium.
Animal research suggests that astragalus has diuretic properties. Theoretically, due to this diuretic effect, astragalus might reduce excretion and increase levels of lithium.
