HelloPharmacist Scorecard of Red Vessel Teapills by Plum Flower

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 4 active ingredients.
  • “Proprietary Extract Blend” is a proprietary blend — the label gives one combined amount (1,360 mg) without saying how much of each component you get.

Red Vessel Teapills contains 4 active ingredients. Three of them are herbal extracts: dong quai (Angelica sinensis), myrrh resin, and frankincense resin (Boswellia carterri).

There's also a proprietary extract blend whose specific components we can't break down from the label. The product also contains several inactive ingredients—microcrystalline cellulose, hydrated magnesium silicate, maltose, activated charcoal, and china wax—which serve as fillers and binders in the tablet.

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: Traditional Chinese medicine circulation and pain support.
  • We looked for evidence on: Back pain, Dysmenorrhea, Osteoarthritis, Sciatica, Menopausal symptoms, Premenstrual syndrome (PMS) — and 4 related terms.
  • The closest evidence on file: Frankincense is rated "Insufficient Reliable Evidence To Rate" for Back pain (Natural Medicines).
  • Also on file: Frankincense is rated "Insufficient Reliable Evidence To Rate" for Osteoarthritis, Wound healing.
  • Also on file: Myrrh is rated "Insufficient Reliable Evidence To Rate" for Back pain, Gingivitis, Wound healing, Sciatica.

The evidence for Red Vessel Teapills is not established in the data we hold. Dong quai has been studied for iron deficiency anemia, osteoporosis, heart disease, migraines, and eczema, but in all cases the evidence is insufficient to rate it.

Myrrh shows likely ineffective evidence for schistosomiasis and insufficient evidence for back pain, cancer, colds, dental issues, and Crohn disease. Frankincense has been studied for acne, aging skin, back pain, cancer-related fatigue, and radiation dermatitis, but again the evidence is insufficient to rate any of these uses.

If you're considering this product for a specific condition, talk with your pharmacist about what research actually supports it.

The evidence, ingredient by ingredient Dong Quai Myrrh Frankincense

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 3 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.

Dong quai is generally well tolerated when taken by mouth, though some people experience burping and flatulence. It can increase your skin's sensitivity to sunlight, so use it with care if you're in the sun.

Myrrh's oral safety isn't well studied; short-term topical or mouth-rinse use appears fine, but at oral doses of 2–4 grams it may cause diarrhea. Frankincense is generally well tolerated short-term, though quality and dosing vary widely between products.

Topically it can rarely cause dermatitis or allergic skin reactions. None of these ingredients should be used during pregnancy—dong quai and myrrh may stimulate the uterus and affect bleeding, and frankincense lacks safety data.

All three should be avoided while breastfeeding due to insufficient safety information.

Side effects, ingredient by ingredient Dong Quai Myrrh Frankincense

Meds to double-check

Major interaction found
Known Interaction Concern · database check
Major identified

At least one ingredient has a documented Major-severity interaction. Check your medications for a personalized result.

Why this rating?
  • 2 of the 3 matched ingredients can interact with medications — Myrrh, Dong Quai.
  • The most serious interaction on file is rated Major.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; diabetes medications.
  • For scale: 249 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 you start Red Vessel Teapills, double-check with your pharmacist if you take warfarin or other blood thinners—dong quai and myrrh can increase bleeding risk or interfere with effectiveness. If you take diabetes medications, myrrh may theoretically increase low blood sugar risk.

If you use estrogen therapy or hormone replacement, dong quai might reduce its effects. We could not check Salvia miltiorrhiza extract against medications, so mention it to your pharmacist too.

For each ingredient in Red Vessel Teapills with known interactions, here are the types of medications they can affect. Open any type for the detail — or search your exact drug in the checker above.

Angelica sinensis extract3 drug types · 163 drugs

Warfarin (Coumadin)

Dong quai may increase the risk of bleeding when used with warfarin.
Case reports suggest that concomitant use of dong quai with warfarin can increase the anticoagulant effects of warfarin and increase the risk of bleeding. In one case, after 4 weeks of taking dong quai 565 mg once or twice daily, the international normalized ratio (INR) increased to 4.9. The INR normalized 4 weeks after discontinuation of dong quai.

Likelihood Probable Evidence D
Anticoagulant/Antiplatelet Drugs

Theoretically, dong quai may increase the risk of bleeding when used with anticoagulant or antiplatelet drugs; however, research is conflicting.
Animal studies suggest that dong quai has antithrombin activity and inhibits platelet aggregation due to its coumarin components. Additionally, some case reports in humans suggest that dong quai can increase the anticoagulant effects of warfarin. However, clinical research in healthy adults shows that taking 1 gram of dong quai root daily for 3 weeks does not significantly inhibit platelet aggregation or cause bleeding. Until more is known, use dong quai with caution in patients taking antiplatelet/anticoagulant drugs.

Likelihood Possible Evidence D
Estrogens

Theoretically, dong quai may reduce the effects of estrogens.
Dong quai has estrogenic effects. Theoretically, concomitant use of large amounts of dong quai might interfere with hormone replacement therapy due to competition for estrogen receptors.

Likelihood Possible Evidence D

Commiphora Myrrha Resin Extract2 drug types · 88 drugs

Antidiabetes Drugs

Theoretically, myrrh might increase the risk of hypoglycemia when taken with antidiabetes drugs.
In vitro and animal research suggests that myrrh has hypoglycemic effects.

Likelihood Possible Evidence D
Warfarin (Coumadin)

Theoretically, myrrh might decrease the effectiveness of warfarin.
In one case, a patient who was previously stable on warfarin had a significant decline in international normalized ratio (INR) following consumption of an aqueous extract of myrrh.

Likelihood Possible Evidence D

Red Vessel Teapills by Plum Flower: Common Questions

Does Red Vessel Teapills by Plum Flower interact with any medications?
Yes. Based on its ingredients, Red Vessel Teapills has a known interaction with 249 medications, including 2 rated major. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Red Vessel Teapills contains 4 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.
Can I use this if I'm pregnant or breastfeeding?
No. Dong quai and myrrh may stimulate the uterus and affect bleeding, so they're not safe in pregnancy. All three main herbs lack enough safety data for breastfeeding, so it's best avoided. Talk to your doctor or pharmacist about what's safe for you at this time.
What are the most common side effects?
Dong quai most commonly causes burping and flatulence. Myrrh at higher doses (2–4 grams) may cause diarrhea. Frankincense is generally well tolerated, though topical use rarely causes skin irritation or dermatitis. Dong quai can also make your skin more sensitive to sunlight.
Does this actually work for anything?
The evidence in our data is not established. All three herbs have been studied for various conditions—anemia, heart disease, back pain, skin conditions, and more—but none have sufficient reliable evidence to say they work. If you're hoping to treat a specific condition, ask your pharmacist what research actually supports using this product for it.
Is myrrh safe to take by mouth?
Myrrh's oral safety isn't well studied. Short-term topical or mouth-rinse use appears fine, but we don't have strong safety data for regular oral use. At doses of 2–4 grams it may cause diarrhea. If you're considering it, talk to your pharmacist.
What is each ingredient supposed to do?
These are traditional herbal remedies used in Chinese medicine, but the product facts don't specify what role each ingredient is meant to play in Red Vessel Teapills. The brand name suggests it may relate to blood vessel health, but we can't confirm that from the label. Your pharmacist or the manufacturer can tell you more about the intended use.
