HelloPharmacist Scorecard of Yun Nan Powder by Ron Teeguarden's Dragon Herbs

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 2 active ingredients.

This powder contains two active ingredients. Notoginseng is a traditional Chinese herb that's been studied for heart and circulation health.

Dioscorea (also known as Chinese yam) is included as well, though we don't have detailed interaction data on file for it. There are no other inactive ingredients listed.

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
Moderate

Some clinical evidence supports this product's ingredients for its stated purpose, but it isn't conclusive.

Why this rating?
  • The label markets this product for: traditional Chinese blood tonic and styptic formula.
  • We looked for evidence on: Bleeding, Bruises, Hypertension, Angina, Coronary heart disease (CHD), Myocardial infarction (MI) — and 4 related terms.
  • The strongest evidence on file: Panax Notoginseng is rated "Possibly Effective" for Angina (Natural Medicines).
  • Also on file: Panax Notoginseng is rated "Possibly Effective" for Stroke.
  • Also on file: Panax Notoginseng is rated "Possibly Ineffective" for Myocardial infarction (MI).

Notoginseng carries research backing for angina and stroke, where it's rated possibly effective — meaning there's some evidence but more study is needed. For heart attack (myocardial infarction), the evidence rates it possibly ineffective.

For liver inflammation (nonalcoholic steatohepatitis), we don't have enough reliable evidence to say. The effectiveness data we hold is for notoginseng only; evidence on dioscorea's role in this product isn't in our facts.

The evidence, ingredient by ingredient Panax Notoginseng

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.

Notoginseng seems to be generally well tolerated when taken by mouth. The most common side effects are dry mouth, flushed skin, insomnia, nausea, nervousness, rash, and vomiting.

Serious side effects are rare. One case report mentions a patient who developed bleeding in the throat area after taking notoginseng with another blood-thinning herb, though it's unclear which ingredient caused it.

The safety data advises against use during pregnancy and breastfeeding — there isn't enough reliable information to know it's safe in these situations. Long-term safety data in humans is limited.

Talk with your doctor or pharmacist before starting this product if you're pregnant, breastfeeding, or planning either.

Side effects, ingredient by ingredient Panax Notoginseng

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?
  • 1 of the 1 matched ingredient can interact with medications — Panax Notoginseng.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs.
  • For scale: 207 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 us before taking this if you're on warfarin or other blood thinners (moderate bleeding risk), aspirin (moderate risk of higher drug levels and side effects), or caffeine-containing medications and products (moderate risk of reduced caffeine effect). Altogether, these interactions span 207 individual medications.

The bottom line

Scorecard at a glanceFormula with limited ingredient disclosure with some supporting evidence for its stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.

Yun Nan Powder is worth a conversation with us before you take it, especially if you're on blood thinners, aspirin, or heavy caffeine. Its notoginseng may help with angina or stroke risk, but the interaction profile is real.

Avoid it if you're pregnant or breastfeeding.

Notoginseng, Powder4 drug types · 207 drugs

Aspirin

Theoretically, taking Panax notoginseng concomitantly with aspirin may increase the risk of adverse effects from both products.
Animal research shows that taking Panax notoginseng extract with aspirin increases blood levels of salicylic acid by approximately 50% and blood levels of Panax notoginseng by 75% to 196%. This effect may be due to increased absorption of both products.

Likelihood Possible Evidence D
Caffeine

Theoretically, taking Panax notoginseng may decrease the levels and clinical effects of caffeine.
Animal research shows that administering Panax notoginseng intravenously for 7 days before intraperitoneal injection of caffeine can decrease maximal blood levels of caffeine by 37%. This interaction is attributed to the ability of Panax notoginseng to increase the activity of cytochrome P450 1A2 (CYP1A2) enzymes.

Likelihood Possible Evidence D
Cytochrome P450 1A2 (Cyp1A2) Substrates

Theoretically, taking Panax notoginseng might reduce the levels and clinical effects of CYP1A2 substrates.
Animal research shows that administering Panax notoginseng intravenously for 7 days before intraperitoneal injection of caffeine can decrease maximal blood levels of caffeine by 37%. This interaction was attributed to the ability of Panax notoginseng to increase the activity of CYP1A2.

Likelihood Possible Evidence D
Warfarin (Coumadin)

Theoretically, taking Panax notoginseng concomitantly with warfarin may increase the risk of bleeding.
Animal research shows that taking Panax notoginseng concomitantly with warfarin increases plasma warfarin levels, prothrombin time, and international normalized ratio when compared with control. In vitro research also suggests that Panax notoginseng may downregulate expression of cytochrome P450 3A4 enzymes, which may affect warfarin metabolism.
