Dan Shen (丹参), commonly known as Chinese Red Sage or Red Sage Root, is the dried root of Salvia miltiorrhiza. It is one of the well-known herbs of Traditional Chinese Medicine (TCM) and has been included in Chinese herbal formulas for centuries.
In traditional TCM terminology, Dan Shen is classified among the herbs that invigorate the Blood. Traditional texts also describe it as helping to dispel Blood stasis, cool the Blood, and calm the Shen.
These expressions describe concepts within the traditional Chinese medical system. They are not claims that Dan Shen treats cardiovascular disease, blood clots, hypertension, insomnia, anxiety, menstrual disorders, or other medical conditions.
Dan Shen is the root of Salvia miltiorrhiza, a perennial plant in the mint family, Lamiaceae. The root is notable for its reddish-brown outer surface, which helps explain the common English name Red Sage Root.
Although Dan Shen belongs to the Salvia genus, it should not be confused with culinary sage or other plants commonly called sage.
Dan Shen may be available as sliced root, powder, concentrated extract, granules, or as an ingredient in traditional Chinese herbal formulas.

Within Traditional Chinese Medicine, herbs are traditionally understood according to characteristics such as taste, temperature, meridian association, and their role within specific TCM patterns.
Dan Shen is traditionally described as:
These descriptions should be understood within the historical framework of TCM. In particular, terms such as Blood, Blood stasis, Heart, Liver, Pericardium, Heat, and Shen have meanings within traditional Chinese medical theory that do not directly correspond to modern biomedical diagnoses.
“Invigorating the Blood” is a traditional TCM expression. It should not automatically be translated into modern statements such as “improves circulation,” “thins the blood,” “prevents clots,” or “protects the heart.”
In TCM, the concept of Blood is part of a broader traditional system used to describe relationships and patterns within the body. A practitioner may select an herb traditionally classified as Blood-invigorating as part of a larger formula based upon the individual's traditional pattern.
Therefore, the traditional classification of Dan Shen does not establish that it treats circulatory or cardiovascular disease.
Blood stasis is another traditional TCM pattern term. It is not the same thing as a blood clot, thrombosis, blocked artery, or other modern medical diagnosis.
Traditional practitioners evaluate a combination of signs and observations before identifying a TCM pattern. Dan Shen may then be selected alone or, more commonly, as one ingredient within a larger herbal formula.
Anyone experiencing chest pain, sudden shortness of breath, weakness, unusual bleeding, or other potentially serious symptoms should seek appropriate medical care rather than attempting to interpret those symptoms as a traditional herbal pattern.
The Shen (神) is an important concept in Traditional Chinese Medicine. It is sometimes translated as “spirit” or “mind,” although neither English word completely captures its traditional meaning.
Traditional references describe Dan Shen as having a secondary role in calming the Shen in certain TCM patterns.
This traditional description does not mean that Dan Shen has been established to treat anxiety, depression, trauma, insomnia, or another mental health or sleep disorder.
Traditional Chinese Medicine associates Dan Shen with the Heart and Pericardium meridians. This is one reason historical descriptions and traditional formulas frequently discuss Dan Shen in connection with the Heart system and Blood.
The TCM concept of the Heart, however, is broader than the anatomical heart recognized in modern medicine.
Traditional Heart-meridian terminology should therefore not be interpreted as evidence that Dan Shen prevents or treats coronary artery disease, heart attack, arrhythmia, hypertension, heart failure, or other cardiovascular conditions.
Dan Shen is especially recognizable because of the reddish to reddish-brown coloration of the dried root exterior. The interior is generally lighter and may range from tan to brownish tones.
Commercial Dan Shen may be sold as whole pieces, sliced root, cut-and-sifted material, powder, concentrated extract powder, or granules.
Color, size, aroma, and appearance can vary according to growing region, harvest, processing, and individual lot.
The Chinese name Dan Shen is sometimes translated or marketed as “red ginseng,” but Dan Shen is not a true ginseng.
Dan Shen is Salvia miltiorrhiza and belongs to the Lamiaceae family. Asian ginseng is Panax ginseng and belongs to the Araliaceae family. They are botanically different plants with different traditional classifications.
Checking the botanical name is one of the best ways to make sure you are purchasing the herb you intend to use.
Dried Dan Shen root has traditionally been used in decoctions, in which herbs are simmered in water as part of a traditional preparation.
Today, Dan Shen is also available in several convenient forms:
These forms are not interchangeable by weight. Concentrated extracts and granules can differ substantially from ordinary dried root, so follow the directions provided for the specific product.
Traditional Chinese herbalism frequently uses combinations of herbs rather than treating every herb as a stand-alone ingredient.
A formula may contain herbs with different traditional roles. Some may represent the primary focus of the formula, while others traditionally complement, balance, or direct the overall composition.
Dan Shen's traditional role therefore depends upon the complete formula rather than simply the presence of Dan Shen on an ingredient list.
Dan Shen appears in a number of traditional Chinese herbal combinations. One historical example is Dan Shen Yin, traditionally composed around Dan Shen with additional herbs such as Tan Xiang and Sha Ren.
Dan Shen may also appear in more complex traditional formulas selected according to TCM pattern differentiation.
Historical formula uses are presented for educational purposes. The traditional indications of a formula should not be interpreted as modern claims that the formula or its individual ingredients treat a disease.
Salvia miltiorrhiza contains a complex mixture of naturally occurring plant compounds. Its chemistry has received considerable scientific attention.
Two major groups frequently discussed in research are lipid-soluble diterpenoid compounds and water-soluble phenolic compounds.
Researchers have studied constituents including:
The amounts and proportions of these compounds can vary according to plant material, growing conditions, processing, extraction method, and the preparation being studied.
Dan Shen is an extensively researched Chinese botanical. Researchers have investigated Salvia miltiorrhiza, its extracts, and isolated constituents in numerous experimental settings.
Areas of scientific investigation include:
This research is scientifically interesting, but it is important to distinguish what researchers are studying from what has been established as a benefit of a commercial herbal product.
Laboratory experiments, animal research, isolated constituents, concentrated extracts, and pharmaceutical preparations may not represent the effects of drinking Dan Shen tea, using dried root, or taking a particular dietary supplement.
For customers who would like to explore the scientific literature, the following PubMed searches provide a useful starting point:
Research Note: Research involving Salvia miltiorrhiza, isolated constituents, extracts, laboratory models, animals, or pharmaceutical preparations does not establish that a specific Dan Shen product has the same effects in humans. Research is provided for educational purposes and is not intended as a claim about products sold by 1st Chinese Herbs.
Because common herbal names can sometimes refer to more than one plant, botanical identity is particularly important when purchasing Chinese herbs.
When choosing Dan Shen, look for:
For concentrated extracts, check the individual product information rather than assuming that all Dan Shen powders have the same concentration.
Dan Shen deserves particular attention to safety because published research has investigated its potential effects on platelet and coagulation-related mechanisms and its possible interactions with medications.
Consult a qualified healthcare professional before using Dan Shen if you take prescription medications, particularly anticoagulant or antiplatelet medications.
Professional guidance is also appropriate if you:
Do not use Dan Shen as a replacement for prescribed cardiovascular, anticoagulant, antiplatelet, psychiatric, sleep, or other medication.
Dan Shen is the Chinese herbal name for the root of Salvia miltiorrhiza. It has a long history of use in Traditional Chinese Medicine and is traditionally classified among herbs that invigorate the Blood.
Dan Shen is commonly called Chinese Red Sage or Red Sage Root. Because common names can be ambiguous, look for the botanical name Salvia miltiorrhiza when identifying Dan Shen.
No. Dan Shen is Salvia miltiorrhiza and is not botanically related to true ginseng such as Panax ginseng.
The root is the part traditionally used in Chinese herbal preparations.
“Invigorates the Blood” is a traditional Chinese medicine classification. It describes Dan Shen's historical role within TCM pattern theory and should not be interpreted as a claim that the herb improves circulation, prevents blood clots, or treats cardiovascular disease.
The Shen is a traditional TCM concept often translated as spirit or mind. Saying that Dan Shen traditionally “calms the Shen” does not mean that the herb has been established to treat anxiety, depression, insomnia, or another mental health or sleep disorder.
Not necessarily. Ordinary powder may simply be dried Dan Shen root ground into a fine powder. An extract powder is produced through an extraction and concentration process. Always check the individual product description and directions.
Dan Shen has been investigated for potential interactions involving coagulation and platelet function. Anyone taking anticoagulant or antiplatelet medication should consult their physician or pharmacist before using Dan Shen.
Dan Shen has a long history in traditional Chinese herbalism and is the subject of substantial modern research. That history and research should not be interpreted as a recommendation to use a Dan Shen product to treat heart disease or another cardiovascular condition. People with cardiovascular disease should follow the treatment plan provided by their healthcare professional.
Dan Shen is an excellent herb for anyone interested in learning how traditional Chinese herbal classifications differ from modern biomedical terminology. Its distinctive red root, long history of use, complex phytochemistry, and continued scientific study have made Salvia miltiorrhiza one of the better-known Chinese herbal botanicals.
When shopping for Dan Shen, compare the botanical identity, plant part, form, concentration, and product-specific quality information. Cut root, ordinary powder, concentrated extract, and traditional formulas are different preparations and should not automatically be used interchangeably.
Terms such as “invigorate the Blood,” “Blood stasis,” “cool the Blood,” “calm the Shen,” “Heart,” “Liver,” “Pericardium,” “Heat,” “meridians,” and similar expressions describe concepts within Traditional Chinese Medicine. They are provided for historical and educational purposes and should not be interpreted as modern medical diagnoses or as claims that Dan Shen diagnoses, treats, cures, or prevents a disease.
