## Overview

Dan Shen (Salvia miltiorrhiza) contains tanshinones and salvianolic acids that improve [cardiovascular health](/ingredients/condition/heart-health) by dilating blood vessels and reducing [inflammation](/ingredients/condition/inflammation). This Traditional Chinese Medicine herb enhances blood circulation and supports heart health through multiple molecular pathways.

## Health Benefits

- Dan Shen improves [cardiovascular health](/ingredients/condition/heart-health) by enhancing blood circulation and reducing arterial plaque formation. - It supports [liver function](/ingredients/condition/detox) by promoting detoxification processes, aiding in the elimination of toxins. - This herb has [anti-inflammatory](/ingredients/condition/inflammation) properties that can alleviate symptoms of chronic inflammation by inhibiting inflammatory mediators. - Dan Shen enhances mental clarity by increasing cerebral blood flow, improving focus and [cognitive function](/ingredients/condition/cognitive). - It supports immune health by boosting the activity of immune cells, enhancing the body's defense mechanisms. - The herb aids in skin health by promoting [collagen synthesis](/ingredients/condition/skin-health), leading to improved skin elasticity and appearance. - It can reduce stress levels by modulating [cortisol](/ingredients/condition/stress) production, promoting a sense of calm and relaxation.

## Mechanism of Action

Dan Shen's tanshinones (tanshinone I, IIA) and salvianolic acids enhance nitric oxide production, promoting vasodilation and improved blood flow. These compounds inhibit platelet aggregation through cyclooxygenase pathways and reduce [inflammatory](/ingredients/condition/inflammation) markers like TNF-α and IL-6. The herb also activates the Nrf2 pathway, providing [antioxidant protection](/ingredients/condition/antioxidant) to [cardiovascular](/ingredients/condition/heart-health) tissues.

## Clinical Summary

Multiple randomized controlled trials with 50-200 participants show Dan Shen extract (200-600mg daily) improves coronary blood flow by 15-25% in patients with coronary artery disease. A systematic review of 23 studies found significant improvements in angina symptoms and exercise tolerance. However, most studies are short-term (4-12 weeks) and conducted primarily in Asian populations. Evidence for liver protection comes mainly from animal studies, with limited human clinical data.

## Nutritional Profile

Dan Shen (Salvia miltiorrhiza) is a medicinal herb rather than a dietary food source, so its nutritional profile is characterized primarily by its bioactive phytochemical compounds rather than conventional macronutrients. Macronutrient content per 100g dried root (approximate): Carbohydrates 45-55g (including polysaccharides 15-20g), Protein 10-15g, Fiber 25-30g, Fat 2-4g, Moisture 8-12%. Key bioactive compounds fall into two primary chemical classes: (1) Lipophilic diterpenoids (tanshinones) - Tanshinone IIA: 1-5 mg/g dried root (most abundant and studied), Tanshinone I: 0.5-2 mg/g, Cryptotanshinone: 0.5-3 mg/g, Dihydrotanshinone I: 0.2-1 mg/g; (2) Hydrophilic phenolic acids - Salvianolic acid B (magnesium lithospermate B): 20-60 mg/g dried root (highest concentration phenolic), Salvianolic acid A: 1-5 mg/g, Rosmarinic acid: 5-15 mg/g, Danshensu (3,4-dihydroxyphenyllactic acid): 2-8 mg/g, Protocatechuic aldehyde: 0.5-2 mg/g. Mineral content per 100g: Potassium 800-1200 mg, Calcium 300-500 mg, Magnesium 150-250 mg, Iron 15-30 mg, Zinc 2-5 mg, Manganese 10-20 mg, Copper 1-3 mg. Vitamin content is modest: Vitamin E (alpha-tocopherol) 2-5 mg/100g, small amounts of B vitamins including B1 (0.1-0.3 mg), B2 (0.2-0.4 mg), and niacin (1-3 mg). Bioavailability notes: Tanshinones exhibit poor water solubility and low oral bioavailability (estimated 1-5% for Tanshinone IIA) due to lipophilic nature; bioavailability is significantly enhanced with lipid-based formulations or nanoparticle delivery systems. Salvianolic acids are water-soluble with moderate oral bioavailability (10-30%), though they undergo extensive first-pass [metabolism](/ingredients/condition/weight-management). Polysaccharide fractions (molecular weight 10-100 kDa) demonstrate [immunomodulatory](/ingredients/condition/immune-support) activity with bioavailability dependent on [gut microbiome](/ingredients/condition/gut-health) metabolism. Co-administration with piperine has been shown to increase tanshinone absorption by up to 2-fold. Standard clinical preparations use hydroalcoholic extracts (30-70% ethanol) to capture both lipophilic and hydrophilic fractions simultaneously.

## Dosage & Preparation

The typical dosage for Dan Shen is 9-15 grams per day. Consult a healthcare provider before use.

## Safety & Drug Interactions

Dan Shen is generally well-tolerated but can cause mild gastrointestinal upset and dizziness in some users. It significantly interacts with warfarin and other anticoagulants, potentially increasing bleeding risk due to its antiplatelet effects. The herb may enhance the effects of [blood pressure](/ingredients/condition/heart-health) medications, requiring dosage adjustments. Pregnant and breastfeeding women should avoid Dan Shen due to insufficient safety data and potential uterine stimulation.

## Scientific Research

Research on Dan Shen includes randomized controlled trials and meta-analyses that suggest its efficacy in improving [cardiovascular health](/ingredients/condition/heart-health). It is well-studied for its potential benefits in heart disease management.

## Historical & Cultural Context

Dan Shen has been used in Chinese medicine for centuries, valued for its ability to invigorate blood and support heart health. It is a staple in many traditional formulations for [cardiovascular](/ingredients/condition/heart-health) conditions.

## Frequently Asked Questions

### What is the best dosage of Dan Shen for heart health?

Clinical studies typically use 200-600mg of standardized Dan Shen extract daily, divided into 2-3 doses. Traditional preparations use 5-15g of dried root daily, but standardized extracts are preferred for consistent potency.

### Can Dan Shen be taken with blood pressure medications?

Dan Shen may enhance the effects of blood pressure medications, potentially causing hypotension. Consult your healthcare provider before combining, as dosage adjustments may be necessary to prevent excessive blood pressure lowering.

### How long does it take for Dan Shen to improve circulation?

Most clinical studies show improvements in blood flow markers within 2-4 weeks of consistent use. However, optimal cardiovascular benefits typically develop over 8-12 weeks of regular supplementation with standardized extracts.

### What are the main active compounds in Dan Shen?

Dan Shen contains two main groups of bioactive compounds: lipophilic tanshinones (tanshinone I, IIA, IIB) and water-soluble salvianolic acids (salvianolic acid A and B). These compounds work synergistically to provide cardiovascular and anti-inflammatory benefits.

### Is Dan Shen safe for people taking blood thinners?

Dan Shen has antiplatelet effects and can significantly increase bleeding risk when combined with warfarin, aspirin, or other anticoagulants. This combination should be avoided or carefully monitored by a healthcare professional with regular blood testing.
