Dong Quai Ginseng (Angelica sinensis 'Dong Quai')

Dong Quai Ginseng (Angelica sinensis) contains ferulic acid and acidic polysaccharides that demonstrate anti-inflammatory and antioxidant properties. The ferulic acid component reduces inflammatory markers IL-1β and TNF-α while polysaccharides maintain SOD enzyme activity and glutathione levels.

Origin & History

Dong Quai (Angelica sinensis [Oliv.] Diels) is a perennial herb from the Apiaceae family, indigenous to China and East Asian regions. The medicinal component is derived from the dried root, traditionally processed and extracted using water or organic solvents to obtain over 70 identified bioactive compounds including phthalides, coumarins, and polysaccharides.

Historical & Cultural Context

Known as 'female ginseng,' Dong Quai has been used in Traditional Chinese Medicine for centuries, primarily to treat menstrual disorders, and is described as 'the most popular used as Chinese medicine.' The herb's traditional applications in women's reproductive health are now being investigated through modern biochemical analysis of its 70+ identified compounds.

Health Benefits

• Anti-inflammatory effects: Ferulic acid component reduces inflammatory markers (IL-1β, TNF-α, MMP-1, MMP-13) in chondrocytes (laboratory evidence only)
• Antioxidant protection: Acidic polysaccharides prevent oxidative stress by maintaining SOD activity and GSH levels (animal cell studies)
• Vascular and muscle relaxation: Contains calcium channel-blocking compounds with antispasmodic and vasodilatory effects (mechanism studies only)
• Potential immune support: Polysaccharides demonstrate immunomodulatory effects (preliminary laboratory evidence)
• Traditional menstrual support: Historically used for menstrual disorders, though clinical evidence remains limited

How It Works

Ferulic acid in dong quai ginseng inhibits pro-inflammatory cytokines IL-1β and TNF-α while reducing matrix metalloproteinases MMP-1 and MMP-13 in chondrocytes. The acidic polysaccharides maintain cellular antioxidant defenses by preserving superoxide dismutase (SOD) activity and glutathione (GSH) levels. These compounds work synergistically to modulate inflammatory pathways and oxidative stress responses at the cellular level.

Scientific Research

The research dossier explicitly notes that Dong Quai 'has been used for a variety of conditions, with little evidence,' and no human clinical trials, randomized controlled trials, or meta-analyses with PMIDs are provided in the available sources. The evidence base consists primarily of in-vitro mechanistic studies and traditional use documentation.

Clinical Summary

Current evidence for dong quai ginseng is limited to laboratory and animal cell studies, with no human clinical trials available. Laboratory studies on chondrocytes demonstrate significant reduction in inflammatory markers, while animal cell research shows maintained antioxidant enzyme activity under oxidative stress conditions. Sample sizes and specific quantified outcomes from these preliminary studies have not been extensively documented. Human clinical data is needed to validate these laboratory findings and establish therapeutic efficacy.

Nutritional Profile

Dong Quai (Angelica sinensis) is used primarily as a medicinal herb rather than a food source, so traditional macronutrient profiling is less relevant than its bioactive compound composition. **Key Bioactive Compounds:** • **Ferulic acid:** ~0.1–0.5% of dried root weight; a hydroxycinnamic acid derivative responsible for anti-inflammatory, antioxidant, and platelet aggregation-inhibiting activity; bioavailability is relatively high orally (~40–60% absorption in animal models) with rapid conjugation and renal excretion. • **Z-Ligustilide:** Major phthalide compound, approximately 1.0–5.0% of dried root extract (varies by extraction method); contributes to vasodilatory, antispasmodic, and neuroprotective effects; lipophilic with moderate oral bioavailability but rapid hepatic metabolism. • **Z-Butylidenephthalide:** ~0.1–1.0% of root extract; calcium channel-blocking and smooth muscle-relaxing properties. • **Angelica sinensis polysaccharides (ASP):** ~5–15% of dried root by weight; primarily acidic heteropolysaccharides composed of glucose, galactose, arabinose, rhamnose, and galacturonic acid residues; MW range 20–80 kDa; responsible for immunomodulatory, hematopoietic, and antioxidant effects; oral bioavailability is limited as large polysaccharides require gut microbial degradation. • **Coumarins (osthole, scopoletin, umbelliferone):** Trace to ~0.05–0.3%; contribute to anticoagulant and anti-inflammatory activity. • **Vanillic acid and caffeic acid:** Minor phenolic constituents, typically <0.1%. • **Essential oils (volatile fraction):** ~0.4–0.8% of dried root; composed primarily of phthalides (ligustilide, butylphthalide), terpenes, and sesquiterpenes. **Minerals (per 100 g dried root, approximate):** Iron: 2–5 mg (relevant to traditional use as a 'blood tonic'); Calcium: 40–80 mg; Potassium: 300–500 mg; Zinc: 1–3 mg; Manganese: 1–4 mg; Cobalt and copper in trace amounts. **Vitamins:** Contains small amounts of vitamin B12 (debated; some analyses report ~0.25–0.5 µg/100 g dried root, though this may reflect microbial contamination rather than intrinsic content), vitamin E (tocopherols, ~1–3 mg/100 g), and folate in trace quantities. **Macronutrients (per 100 g dried root, approximate):** Carbohydrates: 60–70 g (largely polysaccharides and fiber); Dietary fiber: 20–30 g; Protein: 6–12 g; Fat: 1–3 g (mostly from essential oil fraction); Moisture: 8–12%. **Bioavailability Notes:** Ferulic acid is best absorbed from aqueous decoctions; phthalides are lipophilic and benefit from co-administration with fats or lipid-based formulations. Polysaccharide bioactivity may depend on gut microbiome composition for partial degradation into bioactive oligosaccharides. Traditional preparation as a water decoction (tang) preferentially extracts polar compounds (ferulic acid, polysaccharides), while alcohol tinctures favor phthalides and coumarins. Concurrent use with anticoagulant medications may enhance bleeding risk due to coumarin content.

Preparation & Dosage

Clinical dosage information is not available in the provided research sources. No standardized extract concentrations or dosing protocols for different formulations (powder, extract, or standardized preparations) are documented in the available evidence. Consult a healthcare provider before starting any new supplement.

Synergy & Pairings

Red clover, Black cohosh, Chasteberry, Evening primrose oil, Vitamin E

Safety & Interactions

Dong quai ginseng may increase bleeding risk and should be avoided with anticoagulant medications like warfarin due to potential enhanced antiplatelet effects. Common side effects may include photosensitivity, gastrointestinal upset, and hormonal fluctuations due to phytoestrogen content. It is contraindicated during pregnancy and breastfeeding as it may stimulate uterine contractions. Individuals with hormone-sensitive conditions should consult healthcare providers before use due to potential estrogenic activity.
