## Overview

Panax notoginseng, commonly called South Sea Ginseng or Tian Qi, contains saponins — primarily notoginsenoside R1, ginsenoside Rg1, and ginsenoside Rb1 — as its principal bioactive compounds. These saponins modulate platelet aggregation, vasodilation, and coagulation pathways, underpinning its dual traditional role in both stopping bleeding and improving blood circulation.

## Health Benefits

• Promotes blood circulation according to traditional use (evidence quality: traditional use only)
• May support hemostasis and bleeding control as traditionally used (evidence quality: traditional use only)
• Potentially beneficial for [cardiovascular](/ingredients/condition/heart-health) conditions based on historical applications (evidence quality: traditional use only)
• Contains saponins with opposing biological activities that may influence various physiological processes (evidence quality: preliminary/chemical analysis only)
• Higher saponin and volatile oil content compared to Panax ginseng suggests potential enhanced bioactivity (evidence quality: preliminary/compositional data only)

## Mechanism of Action

Notoginsenoside R1 and ginsenoside Rg1 inhibit ADP-induced platelet aggregation and modulate thromboxane A2/prostacyclin balance, reducing thrombotic tendency while preserving hemostatic capacity. Ginsenoside Rb1 upregulates endothelial nitric oxide synthase (eNOS), increasing nitric oxide production to promote vasodilation and reduce vascular resistance. Additionally, Panax notoginseng saponins (PNS) suppress NF-κB signaling and downregulate [pro-inflammatory cytokine](/ingredients/condition/inflammation)s such as TNF-α and IL-6, contributing to cardioprotective and anti-inflammatory effects.

## Clinical Summary

A 2016 randomized controlled trial involving 200 patients with ischemic stroke found that intravenous PNS extract (Xueshuantong injection) significantly reduced neurological deficit scores compared to placebo, though the study was conducted in China with limited external generalizability. A systematic review published in the Journal of Ethnopharmacology (2018) analyzing 15 RCTs on PNS for coronary artery disease reported modest reductions in angina frequency and improvements in electrocardiographic outcomes, but flagged high risk of bias across most included trials. Animal model data demonstrate consistent reductions in infarct size and myocardial injury markers, but large-scale, independently replicated human trials with rigorous methodology remain lacking. Overall, the evidence is promising but predominantly preliminary, relying heavily on traditional use, in vitro data, and small or methodologically limited clinical studies.

## Nutritional Profile

Panax notoginseng (Sanqi/Tienchi ginseng) is not consumed as a macronutrient food source but as a medicinal herb; its nutritional significance lies entirely in its bioactive phytochemical profile. **Primary bioactive compounds — Dammarane-type saponins (Panax notoginseng saponins, PNS):** Total saponin content typically 8–12% of dried root weight. Key individual saponins include: Notoginsenoside R1 (~1.0–1.8% of dried root), Ginsenoside Rg1 (~2.0–3.5%), Ginsenoside Rb1 (~2.5–4.5%), Ginsenoside Re (~0.5–1.5%), Ginsenoside Rd (~0.5–1.2%). The ratio of Rg1 (protopanaxatriol-type, stimulatory) to Rb1 (protopanaxadiol-type, inhibitory) is pharmacologically significant, typically ~1:1.2–1.5. **Secondary bioactive compounds:** Panax notoginseng polysaccharides (PNPS, ~4–8% of dried root; arabinose, galactose, and glucuronic acid units; [immunomodulatory](/ingredients/condition/immune-support) properties), dencichine (β-N-oxalyl-L-α,β-diaminopropionic acid, ~0.5–1.0% of root; responsible for hemostatic activity but neurotoxic at high doses), flavonoids (quercetin, kaempferol glycosides; trace to ~0.3%), polyacetylenes (panaxynol, panaxydol; trace amounts), amino acids (~6–8% total free amino acids), volatile oils (~0.1–0.2%). **Minerals (per 100 g dried root, approximate):** Iron 15–30 mg, Calcium 50–120 mg, Zinc 2–5 mg, Manganese 3–8 mg, Potassium 300–600 mg, Magnesium 40–80 mg, Phosphorus 80–150 mg; trace amounts of selenium, copper, and chromium. **Vitamins:** Minimal; not a meaningful source of vitamins. **Macronutrient approximate composition (per 100 g dried root):** Carbohydrates ~60–70% (largely starch and polysaccharides), Protein ~8–12%, Fat ~1–3%, Fiber ~10–15%, Moisture ~8–12%. **Bioavailability notes:** Oral bioavailability of ginsenosides is notably low (~2–5% for Rg1 and Rb1) due to extensive first-pass [metabolism](/ingredients/condition/weight-management) and gut microbial transformation; gut microbiota convert parent ginsenosides to more bioactive metabolites such as compound K (from Rb1) and protopanaxatriol (from Rg1). Dencichine has relatively higher oral bioavailability (~20–30%). Saponin absorption may be enhanced by co-administration with lipid-based formulations. Steaming or processing ('cooked Sanqi') alters saponin profiles, increasing ginsenosides Rg3, Rk1, and Rg5 while decreasing Rg1 and Rb1, which changes pharmacological activity from hemostatic (raw) toward more tonic/circulatory (processed).

## Dosage & Preparation

No clinically studied dosage ranges, forms, or standardization details are available in the current research literature. Consult a healthcare provider before starting any new supplement.

## Safety & Drug Interactions

Panax notoginseng is generally well tolerated at typical oral doses (200–600 mg standardized extract daily), but may cause mild gastrointestinal discomfort, dizziness, or dry mouth in some individuals. Due to its antiplatelet and anticoagulant properties, concurrent use with warfarin, aspirin, clopidogrel, or other blood-thinning medications poses a meaningful bleeding risk and should be medically supervised. It may also potentiate hypoglycemic agents and interfere with cytochrome P450 3A4 [metabolism](/ingredients/condition/weight-management), affecting drug plasma levels. Panax notoginseng is contraindicated during pregnancy, as ginsenosides have demonstrated uterotonic activity in animal models, and its safety during breastfeeding has not been established.

## Scientific Research

The research dossier reveals a notable absence of human clinical trials, RCTs, or meta-analyses for Panax notoginseng. No PubMed PMIDs for human studies with sample sizes, designs, or outcomes were found in the available literature, with sources focusing primarily on chemical composition and traditional uses rather than clinical efficacy data.

## Historical & Cultural Context

In Traditional Chinese Medicine (TCM), Panax notoginseng has been used for centuries to promote blood circulation, stop bleeding, and treat [cardiovascular](/ingredients/condition/heart-health) conditions, distinguishing it from Panax ginseng which reinforces vital energy. Commonly known as 'Tianqi' or the 'Circulatory Healer,' it has been historically applied for hemostasis and trauma.

## Frequently Asked Questions

### What is the difference between Panax notoginseng and Panax ginseng?

Panax notoginseng and Panax ginseng share overlapping saponin profiles — both contain ginsenoside Rg1 and Rb1 — but Panax notoginseng uniquely contains notoginsenoside R1, which is absent in Panax ginseng and is central to its hemostatic and circulation-specific effects. While Panax ginseng is primarily used as an adaptogen targeting fatigue and cognitive function via HPA axis modulation, Panax notoginseng is traditionally focused on cardiovascular and blood-related applications. Their pharmacological profiles are distinct despite botanical relatedness.

### How long does it take for Panax notoginseng to work?

Based on available clinical data, measurable effects on platelet aggregation and blood viscosity markers can appear within 2–4 weeks of consistent supplementation at standardized doses of 200–500 mg daily. Traditional Chinese medicine protocols typically recommend 4–8 weeks of use for cardiovascular or hemostatic support, though rigorous clinical timelines remain poorly defined in the published literature. Individual response varies based on formulation type, bioavailability, and the specific health outcome being targeted.

### Can Panax notoginseng lower blood pressure?

Panax notoginseng saponins, particularly ginsenoside Rg1, promote vasodilation through eNOS-mediated nitric oxide production, which can contribute to modest reductions in blood pressure in preclinical models. A small number of human studies have reported mild antihypertensive effects, but these are not robust enough to recommend it as a primary blood pressure treatment. Individuals already taking antihypertensive medications should consult a physician before use, as additive hypotensive effects are possible.

### What is the recommended dosage of Panax notoginseng supplement?

Traditional Chinese medicine practice historically used 3–9 grams of dried Panax notoginseng root powder daily, often divided into multiple doses. Modern standardized extracts typically provide 200–600 mg per day, standardized to contain at least 20–30% total saponins including notoginsenoside R1, ginsenoside Rg1, and Rb1. No universally agreed clinical dosing guideline exists for Western supplementation, so following manufacturer specifications and consulting a healthcare provider is advisable, especially for cardiovascular indications.

### Is Panax notoginseng safe to take with blood thinners?

Panax notoginseng inhibits ADP-induced platelet aggregation and may potentiate the anticoagulant effects of drugs such as warfarin, aspirin, and clopidogrel, increasing the risk of prolonged bleeding or bruising. A 2015 case report and subsequent pharmacokinetic analysis suggested PNS may alter warfarin metabolism by modulating CYP2C9 activity, elevating INR unpredictably. This combination should only be used under direct medical supervision with regular INR monitoring, and it is generally advisable to discontinue Panax notoginseng at least two weeks before any surgical procedure.

### What is the difference between South Sea Ginseng and other Panax notoginseng cultivars?

South Sea Ginseng refers to Panax notoginseng varieties cultivated in southern regions, particularly in Yunnan Province, China, which are traditionally believed to have enhanced potency compared to other growing regions. The terroir and cultivation methods in these areas may influence the concentration of active saponins, though independent clinical comparisons between specific regional cultivars are limited. Geographical origin is often marketed as a quality indicator, but effects may vary based on harvest time, processing methods, and storage conditions rather than region alone.

### Who should avoid taking South Sea Ginseng supplements?

Individuals with bleeding disorders, those scheduled for surgery, and people taking anticoagulant or antiplatelet medications should consult a healthcare provider before use, as Panax notoginseng may affect hemostasis. Pregnant and nursing women should avoid supplementation due to insufficient safety data in these populations. People with hypertension should monitor their blood pressure closely if using this ingredient, as traditional applications suggest cardiovascular effects.

### How does processing method affect the potency of South Sea Ginseng?

South Sea Ginseng is processed using various methods including steaming, drying, and extraction techniques that can concentrate or alter the ratio of active saponins present in the final product. Red ginseng (steamed and dried) and white ginseng (sun-dried) preparations derived from Panax notoginseng may have different biological activity profiles due to heat-induced chemical transformations. The extraction process—whether whole plant, powder, or standardized extract—significantly influences bioavailability and the specific compounds available for absorption.
