HelloPharmacist Scorecard of Salvia Mil. Dan Shen by Wise Woman Herbals
Our pharmacy team’s full take, with four database checks built into the cards below — a summary of what is known, not a grade of the product itself.
What’s inside
Low disclosure
This liquid contains one active ingredient: Dan Shen (danshen), a traditional herb used in herbal medicine. The product also contains spring water and alcohol as inactive ingredients.
Does it work?
Couldn't assess
The evidence for danshen isn't well established in the data we hold. The product is associated with several traditional uses — acne, unstable angina, coronary heart disease, heart failure, and cirrhosis — but all of these are rated as having insufficient reliable evidence to rate its effectiveness.
That doesn't mean it doesn't work; it means the research available to us doesn't yet support a clear conclusion.
How safe is it?
Well-documented data
Danshen taken by mouth is generally well tolerated, though a small number of people report upset stomach, itching, reduced appetite, drowsiness, dizziness, or headache in trials — though it's not always clear those side effects came from the herb itself. The main safety concern is that danshen affects blood clotting, so short-term use by adults may be appropriate but product quality varies.
The safety data advises against use during pregnancy and breastfeeding because there isn't enough information to know it's safe.
Meds to double-check
Major interaction found
Check your medications against this list before starting: blood thinners and antiplatelet drugs (Major), digoxin or other heart medications (Major), blood pressure drugs, and any medication your liver metabolizes through CYP1A2, CYP2C9, CYP2E1, CYP3A4, or p-glycoprotein pathways (all Moderate). Use the search tool on this page to look up your exact drugs.
The bottom line
Scorecard at a glanceFormula with limited ingredient disclosure with no assessable stated purpose. Major medication interactions have been identified, and safety information is well characterized.
Dan Shen is worth discussing with your pharmacist, especially if you take blood thinners, digoxin, blood pressure medications, or drugs your liver breaks down quickly. If you're pregnant, breastfeeding, or have a bleeding disorder, talk to your pharmacist or doctor first.
This is one where the personalized check matters more than the product alone.

Salvia Mil. Dan Shen by Wise Woman Herbals Drug Interactions
HelloPharmacist Interaction Report
Salvia Mil.
Dan Shen by Wise Woman Herbals contains danshen, an ingredient with a number of significant interactions to be aware of. The most serious concern is with blood thinners and antiplatelet drugs (drugs that prevent clots), where danshen may increase your bleeding risk — this is rated Major severity.
Danshen also interacts at Major severity with digoxin (Lanoxin), a heart medication, potentially raising the risk of adverse effects because of how structurally similar danshen is to cardiac glycosides (heart drugs).
Read the full breakdown — every affected drug type, severity by severity
At Moderate severity, danshen may lower your blood pressure further if you're already on blood pressure medications, and it can affect how your liver metabolizes several classes of drugs — including those broken down by CYP1A2, CYP2C9, CYP2E1, and CYP3A4 enzymes, as well as drugs cleared by p-glycoprotein. Some of these interactions are proven in humans; others are from lab work and remain theoretical.
Altogether, these interactions span 1,045 individual medications.
Before you start this product, use the medication checker below to look up your exact prescriptions. If you take any blood thinners, heart medications, or blood pressure drugs, check with your pharmacist first — don't add this on your own.

For each ingredient in Salvia Mil. Dan Shen with known interactions, here are the types of medications it can affect. Open any type for the detail — or search your exact drug in the checker above.
Dan Shen
Anticoagulant/Antiplatelet Drugs
Theoretically, danshen may increase the risk of bleeding if used with anticoagulant or antiplatelet drugs.
Danshen has been reported to have antithrombotic effects. Animal research also suggests that taking a danshen combination formula with clopidogrel exhibits a synergistic increase in antiplatelet aggregation and prolongation of coagulation time when compared with either taken alone.
Digoxin (Lanoxin)
Theoretically, using danshen with digoxin might increase the risk of adverse effects.
Danshen has structural and pharmacological similarities to cardiac glycosides.
Amlodipine (Norvasc)
Theoretically, taking danshen in combination with amlodipine may decrease the clinical effects of amlodipine.
In animal research, taking danshen orally in combination with amlodipine reduced blood levels of amlodipine by about 52%. This may have been due to induction of cytochrome P450 3A4 (CYP3A4) by danshen, which has been demonstrated in vitro. So far, this interaction has not been reported in humans.
Antihypertensive Drugs
Theoretically, taking danshen with antihypertensive drugs might increase the risk of hypotension.
Animal research suggests that danshen can produce dose-dependent hypotensive effects. Furthermore, concomitant use with captopril appears to potentiate this effect.
Aspirin
Theoretically, danshen may increase the levels of aspirin and the risk of bleeding.
Research in healthy adult males shows that taking a combination of danshen and kudzu with aspirin increases plasma aspirin area under the curve by approximately 3.4-fold. Animal research also shows that taking a combination of danshen and kudzu (danshen-gegen formula) with aspirin increases maximal blood levels of aspirin and salicylic acid by approximately 4-fold and 3.7-fold, respectively, without impacting blood loss. Taking danshen increases the antiplatelet activity of aspirin and might increase the side effects of aspirin.
Clopidogrel (Plavix)
Theoretically, danshen may increase the risk of bleeding if taken with clopidogrel.
Clopidogrel is an antiplatelet prodrug that is metabolized by carboxyl esterase 1 (CES1) to an inactive metabolite. Animal research shows that a danshen combination formula decreases the activity of CES1, decreasing levels of the inactive metabolite in the blood and possibly increasing levels of the active metabolite. Animal research also suggests that taking a danshen combination formula with clopidogrel exhibits a synergistic increase in antiplatelet aggregation and prolongation of coagulation time when compared with either taken alone.
Cytochrome P450 1A2 (Cyp1A2) Substrates
Theoretically, danshen may increase the levels and clinical effects of drugs metabolized by CYP1A2.
In vitro research shows that danshen tincture and various constituents of danshen inhibit the activity of CYP1A2. However, this activity has not been shown in humans when theophylline, a CYP1A2 substrate, was used as a target drug.
Cytochrome P450 2C9 (Cyp2C9) Substrates
Theoretically, danshen may increase the levels and clinical effects of drugs metabolized by CYP2C9.
In vitro research shows that various constituents of danshen inhibit the activity of CYP2C9. So far, this interaction has not been reported in humans.
Cytochrome P450 2E1 (Cyp2E1) Substrates
Theoretically, danshen may increase the levels and clinical effects of drugs metabolized by CYP2E1.
In vitro research shows that various constituents of danshen inhibit the activity of CYP2E1. So far, this interaction has not been reported in humans.
Cytochrome P450 3A4 (Cyp3A4) Substrates
Danshen might alter the levels and clinical effects of drugs metabolized by CYP3A4.
Preliminary clinical research in healthy males shows that the administration of danshen for 10-14 days induces intestinal CYP3A4 and increases the clearance of midazolam, a CYP3A4 substrate. The maximum concentration of midazolam was decreased by 31% to 67%, and drug levels were decreased by 27% to 80%. However, a single dose of danshen has the opposite effect, increasing maximum concentrations of midazolam by 87%.
Fexofenadine (Allegra)
Danshen might increase the levels and clinical effects of fexofenadine.
Pharmacokinetic research in healthy volunteers shows that taking danshen extract 1 gram three times daily for 10 days prior to receiving fexofenadine 60 mg increases peak levels of fexofenadine, a p-glycoprotein substrate, by 27.4% and area under the curve (AUC) by 37.2%.
Glucuronidated Drugs
Theoretically, danshen might affect the levels and clinical effects of drugs requiring glucuronidation.
In vitro research shows that danshen induces the expression of glucuronosyltransferases. However, it also inhibits the activity of glucuronosyltransferases, including various members of the 1A and 2B families. The extent of inhibition of a specific glucuronosyltransferase seems to be dependent on whether or not the danshen is processed via 'sweating'. This type of processing may affect the levels of constituents in danshen that alter glucuronosyltransferase activity. So far, this interaction has not been reported in humans.
Midazolam (Versed)
Danshen might alter the levels and clinical effects of midazolam.
Preliminary clinical research in healthy males shows that the administration of danshen for 10-14 days induces intestinal CYP3A4 and increases midazolam clearance. The maximum concentration was decreased by 31% to 67%, and drug levels were decreased by 27% to 80%. However, a single dose of danshen has the opposite effect, increasing maximum concentrations of midazolam by 87%.
P-Glycoprotein Substrates
Danshen might alter the levels of drugs cleared by p-glycoprotein.
Pharmacokinetic research in healthy volunteers suggests that danshen might affect p-glycoprotein activity. Taking danshen extract 1 gram three times daily for 10 days prior to receiving fexofenadine 60 mg increases peak levels of fexofenadine, a p-glycoprotein substrate, by 27.4% and area under the curve (AUC) by 37.2%.
Rosuvastatin (Crestor)
Theoretically, danshen might increase the levels and clinical effects of rosuvastatin.
Animal research shows that a single dose of danshen increases levels of rosuvastatin at least 2-fold, possibly by increasing absorption and/or decreasing elimination. So far, this interaction has not been reported in humans.
Warfarin (Coumadin)
Theoretically, danshen may increase the risk of bleeding if used with warfarin.
There have been several case reports of increased international normalized ratio (INR) after concomitant use of danshen and warfarin. Elevations in INR have occurred as early as 3-5 days after start of danshen. However, a clinical trial in adults taking warfarin with stable INR found that the addition of compound danshen dripping pills, containing danshen extract, Panax notoginseng, and borneol, 270 mg three times daily for 4 weeks did not alter INR levels or the average required warfarin dose when compared to baseline. These findings are consistent with animal research, which found no change in warfarin pharmacokinetics with the use of danshen. Other research in healthy adult males also shows that taking a combination of danshen and kudzu with warfarin does not increases plasma warfarin area under the curve, but may reduce plasma soluble thrombomodulin levels. However, other research shows that danshen might increase the rate of absorption and decrease the elimination rate of warfarin. Also, research in healthy adult males shows that taking a combination of danshen and kudzu with warfarin increases plasma area under the curve of danshensu, a constituent of danshen, by approximately 29.5-fold. Danshen should be used cautiously in patients taking warfarin.
