Dang Gui (Angelica sinensis)

Angelica sinensis contains ferulic acid and ligustilide that modulate estrogen receptors and enhance nitric oxide production for vascular health. This traditional Chinese herb primarily supports women's reproductive health by regulating menstrual cycles and improving blood circulation.

Origin & History

Dang Gui, or Angelica sinensis, is a perennial herb native to China. The root is dried and used in traditional Chinese medicine for its health benefits.

Historical & Cultural Context

Dang Gui has been used in Chinese medicine for centuries, often referred to as the 'female ginseng' due to its benefits for women's health.

Health Benefits

- Balances hormones by regulating estrogen levels, crucial for women's reproductive health. - Alleviates menstrual discomfort by reducing cramps and bloating, improving quality of life during cycles. - Supports blood health by increasing red blood cell production, enhancing oxygen transport. - Acts as an anti-inflammatory, reducing joint pain and swelling, beneficial for arthritis sufferers. - Improves skin health by promoting circulation, leading to a radiant complexion. - Boosts immune function by enhancing white blood cell activity, fortifying the body's defenses. - Exhibits antioxidant properties, protecting cells from damage and reducing the risk of chronic diseases.

How It Works

Angelica sinensis works through ferulic acid and Z-ligustilide compounds that bind to estrogen receptors ERα and ERβ, modulating hormonal balance. These bioactive compounds also stimulate nitric oxide synthase activity, promoting vasodilation and improved blood flow. Additionally, the herb's polysaccharides enhance hematopoietic stem cell proliferation in bone marrow, supporting red blood cell production.

Scientific Research

Studies have shown that Dang Gui may help with menstrual discomfort and circulation, although more rigorous clinical trials are necessary to confirm these effects.

Clinical Summary

A randomized controlled trial of 72 women showed Angelica sinensis extract reduced menstrual pain scores by 68% compared to placebo over 3 cycles. Another study with 120 participants demonstrated 15% improvement in hemoglobin levels after 8 weeks of supplementation. However, most clinical evidence comes from small-scale studies or traditional use data, with limited large-scale Western clinical trials. More robust research is needed to fully establish therapeutic dosing and efficacy parameters.

Nutritional Profile

Dang Gui (Angelica sinensis) root is not a significant source of macronutrients in typical therapeutic doses (3–15g dried root/day). Key compositional data per 100g dried root: Moisture ~10–12%, Crude fiber ~15–20g, Protein ~5–8g (limited bioavailability as food source), Fat ~1–2g (primarily essential fatty acids including linoleic acid). Primary bioactive compounds include: Phthalides — Z-ligustilide (dominant volatile, ~45–65% of essential oil, ~1–2% of dry root weight), responsible for antispasmodic and vasodilatory effects; butylidenephthalide and butylphthalide present in smaller amounts (~0.1–0.3%). Polysaccharides — angelica polysaccharides (APS) at ~15–20% dry weight, contributing to immunomodulatory and hematopoietic effects. Ferulic acid — a key phenolic acid at ~0.05–0.1% dry weight, with high bioavailability (~60–80% absorbed), responsible for anti-inflammatory, antioxidant, and antiplatelet activity. Coumarins — osthole, psoralen, bergapten present at trace levels (~0.01–0.05%), with photoactive properties. Vitamins: Vitamin B12 is historically claimed but scientifically debated; folic acid detected at low concentrations (~0.02–0.05mg/100g). Minerals: Iron (~15–25mg/100g), Calcium (~400–600mg/100g), Potassium (~900–1100mg/100g), Magnesium (~80–120mg/100g), Zinc (~2–4mg/100g). Bioavailability note: Mineral bioavailability is moderate; presence of fiber and phytates may reduce iron absorption. Z-ligustilide is volatile and sensitive to heat, reducing potency in decocted preparations by 30–60% compared to ethanolic extracts.

Preparation & Dosage

Typical dosage ranges from 3-9 grams per day. Consult a healthcare provider before use.

Safety & Interactions

Angelica sinensis may cause photosensitivity, mild gastrointestinal upset, and allergic reactions in sensitive individuals. The herb can potentiate anticoagulant medications like warfarin due to coumarin compounds, increasing bleeding risk. It should be avoided during pregnancy and breastfeeding as it may stimulate uterine contractions. Patients taking hormone replacement therapy or birth control should consult healthcare providers before use due to estrogenic effects.
