WARNING: DISCLAIMER: The below uses are based on tradition, scientific theories, or limited research. They often have not been thoroughly tested in humans, and safety and effectiveness have not always been proven. Some of these conditions are potentially serious, and should be evaluated by a qualified healthcare provider. There may be other proposed uses that are not listed below.


Adults (18 years and older)

Oral dosing has not been studied in well-conducted trials in humans, and therefore no specific dose can be recommended.

In research from the 1970s, an 8 milliliter injection of danshen (16 grams of the herb) was given intravenously (diluted in 500 milliliters of a 10% glucose solution) for up to four weeks for ischemic stroke. Safety and effectiveness have not been established for this route of administration and it cannot be recommended at this time.

Children (younger than 18 years)

There is not enough scientific evidence to recommend the safe use of danshen in children, and it should be avoided due to potentially serious side effects.


DISCLAIMER: Many complementary techniques are practiced by healthcare professionals with formal training, in accordance with the standards of national organizations. However, this is not universally the case, and adverse effects are possible. Due to limited research, in some cases only limited safety information is available.


People with known allergy to danshen (Salvia miltiorrhiza) or its constituents (such as protocatechualdehyde, 3,4-dihydroxyphenyl-lactic acid, tanshinone I, dihydrotanshinone, cryptotanshione, miltirone, or salvianolic acid B) should avoid this herb. Danshen is often found in combination with other herbs in various formulations, and patients should read product labels carefully. Signs of allergy may include rash, itching, or shortness of breath.

Side Effects and Warnings

Danshen may increase the risk of bleeding. This herb is reported to inhibit platelet aggregation and to increase the blood-thinning effects of warfarin in humans. Caution is advised in patients with bleeding disorders, in patients taking drugs that may increase the risk of bleeding, and prior to some surgical procedures. Dosing adjustments may be necessary.

Some people may experience stomach discomfort, reduced appetite, or itching.

In theory, danshen may lower blood pressure and should be used cautiously by patients with blood pressure abnormalities or taking drugs that alter blood pressure.

In theory, a chemical found in danshen called miltirone may increase drowsiness. Caution is advised while driving or operating machinery.

Convulsions, mental changes, and dystonia syndrome may occur.

Pregnancy and Breastfeeding

Danshen should be avoided during pregnancy and breastfeeding. In theory, the blood-thinning properties of danshen may increase the risk of miscarriage or bleeding, and effects on the fetus or nursing infants are not known.
