HelloPharmacist Scorecard of Yun Nan Capsules 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 Oct 1, 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.
  • “Proprietary Extract Formula” is a proprietary blend — the label gives one combined amount (1,500 mg) without saying how much of each component you get.

Yun Nan Capsules contains two active herbal extracts: Notoginseng Root Extract and Dioscorea Root Extract (wild yam). The formula is delivered in gelatin capsules.

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: circulatory health and immune system enhancement.
  • We looked for evidence on: Angina, Atherosclerosis, Bleeding, Bruises, Coronary heart disease (CHD), Hypertension — 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).

The data we hold shows Notoginseng Root Extract is possibly effective for angina, stroke, and intracranial hemorrhage, but possibly ineffective for heart attack. For nonalcoholic fatty liver disease (NASH), the evidence isn't established.

Dioscorea Root Extract appears possibly ineffective for menopausal symptoms; for gallbladder disease, sexual dysfunction, painful periods, and infertility, the evidence isn't established in our data.

The evidence, ingredient by ingredient Panax Notoginseng Wild Yam

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 2 of the 2 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 2 of 2.
  • General safety write-ups exist for 2 of 2.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Notoginseng Root Extract seems generally well tolerated short-term in healthy adults, though quality human safety data are limited. Common side effects taken by mouth are dry mouth, flushed skin, trouble sleeping, nausea, nervousness, rash, and vomiting.

The safety data advise against this ingredient during pregnancy and breastfeeding because there isn't enough information. Dioscorea Root Extract is likely fine for short-term use in healthy adults, but long-term safety isn't well studied.

When taken by mouth it's generally well tolerated; common side effects are fever, headache, upset stomach, and vomiting. The safety data advise against it during pregnancy and breastfeeding.

Side effects, ingredient by ingredient Panax Notoginseng Wild Yam

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?
  • 2 of the 2 matched ingredients can interact with medications — Panax Notoginseng, Wild Yam.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs.
  • For scale: 219 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 taking Yun Nan Capsules, check with your doctor or pharmacist if you take blood thinners like warfarin (Coumadin) — there's a Moderate risk of increased bleeding. Also check if you take aspirin, estrogen-based birth control or hormone therapy, caffeine supplements, or medications broken down by a liver enzyme called CYP1A2, all of which have Moderate interactions documented.

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.

This product is meant for adults looking to support circulation and overall wellness using traditional herbal extracts. If you take blood thinners, aspirin, birth control, hormone therapy, or any medications processed by your liver, you'll need to check your exact drugs with your doctor or pharmacist before starting — the interactions are real and could affect how your medications work or increase your bleeding risk.

Pregnancy and breastfeeding are not recommended. Talk it over with your own healthcare provider before you begin.

Notoginseng Root Extract4 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.

Likelihood Possible Evidence D
Notoginseng Root Extract full monograph & interactions

Dioscorea Root Extract1 drug type · 41 drugs

Estrogens

Theoretically, wild yam might increase or decrease the effects of estrogen.
Wild yam root shows estrogenic and anti-estrogenic effects in vitro. Theoretically, wild yam might interfere with hormone therapy.
