Danshen (Salvia miltiorrhiza): what it does and how people use it

Danshen is a traditional Chinese herb used for heart and circulation problems. You’ll see it as dried root, powder, capsules, or concentrated extracts. People use it for chest pain, poor circulation, and some liver issues. Below I’ll explain what evidence exists, how it’s commonly taken, and what to watch for so you can decide if it’s worth trying.

Uses & benefits

Historically, practitioners used danshen to "invigorate blood" and ease chest tightness. Modern research—mostly small clinical trials and lab studies—suggests active compounds in danshen can improve blood flow, reduce clotting, and act as mild antioxidants. That doesn’t mean it’s a cure-all, but for people with mild circulation problems or as a complement to other care, it can help. Some people report less cold hands and feet, reduced leg cramps, or easier recovery after minor vascular procedures.

Common forms include capsule supplements standardized to tanshinones and salvianolic acids, liquid extracts for faster absorption, and powdered root for teas. Standardization matters: look for products that list active compound amounts so you know what you’re getting.

Safety, dosage, and interactions

Dosage varies by product. Typical supplement doses fall between 500 mg and 2,000 mg per day for dried root or equivalent extract amounts. Traditional Chinese formulations and concentrated extracts use different potencies, so follow the product label or a practitioner’s advice. Start low and monitor how you feel.

Major safety points: danshen can thin the blood and may increase bleeding risk. Don’t use it with blood thinners like warfarin, direct oral anticoagulants, or if you have a bleeding disorder without medical approval. It also can interact with some blood pressure drugs and certain chemotherapy agents. If you’re pregnant or breastfeeding, avoid it—there’s not enough safety data.

Side effects are usually mild: stomach upset, headache, or rash. Severe reactions are rare but get medical help for signs of excessive bleeding or allergic reactions.

Where to buy: choose well-known brands or suppliers that provide third-party testing (USP, NSF, or an independent lab report). Read labels for standardized active amounts and avoid products with vague ingredient lists. If you’re buying online, check reviews and the seller’s return policy.

Questions to ask your clinician: Could danshen affect my prescriptions? Is it safe with my condition? How should I time it around other meds? A short talk with your doctor can prevent risky interactions.

Want a quick starter plan? Pick a standardized capsule, begin at the lowest recommended dose for two weeks, watch for bruising or unusual bleeding, and check in with your clinician. If you notice clear benefits and no issues, you can consider continuing under medical guidance.
