• Acne. Although there is interest in using oral and topical asparagus for acne, there is insufficient reliable information about the clinical effects of asparagus for this condition.
• Cancer. Although there is interest in using oral asparagus for cancer, there is insufficient reliable information about the clinical effects of asparagus for this condition.
• Constipation. Although there is interest in using oral asparagus for constipation, there is insufficient reliable information about the clinical effects of asparagus for this purpose.
• Intestinal parasite infection. Although there is interest in using oral asparagus for intestinal parasite infection, there is insufficient reliable information about the clinical effects of asparagus for this condition.
• Hypertension. Oral asparagus has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: Preliminary clinical research in adults with hypertension shows that taking a specific combination product (Asparagus-P, Grunwalder) containing asparagus root 6 grams and parsley leaf 6 grams daily for 6 weeks does not affect ambulatory blood pressure when compared with baseline (94940).
• Kidney stones (nephrolithiasis). Although there is interest in using oral asparagus for kidney stones, there is insufficient reliable information about the clinical effects of asparagus for this condition.
• Obesity. Oral asparagus has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: Observational research in overweight adults shows that taking psyllium 2-3 tablespoons each morning with 1.5 liters of elderflower juice, plus tablets providing asparagus powder 2.7 grams, elderberry powder 225 mg, and elderflower extract 600 mg daily for 2 weeks, and replacing each meal on days 5-12 with 200 mL of elderberry and elderflower juice, is associated with an average 3.2 kg weight loss and a modest reduction in blood pressure when compared with baseline (94939). It is not known if these effects are due to asparagus, other ingredients, the combination, or fasting from regular food for 8 days. Furthermore, the validity of these findings is limited by the lack of a comparator group.
• Rheumatoid arthritis (RA). Although there is interest in using oral asparagus for RA, there is insufficient reliable information about the clinical effects of asparagus for this condition.

• Acne. Although there is interest in using oral danshen for acne, there is insufficient reliable information about the clinical effects of danshen for this condition.
• Angina. Preliminary clinical research suggests that compound danshen dripping pill, containing danshen extract, Panax notoginseng, and borneol, reduces symptoms and improves electrocardiogram (ECG) parameters in adults with angina. The effect of danshen alone is unclear. Details: Analyses of preliminary clinical research, as well as individual lower-quality clinical studies, have shown that danshen dripping pill is effective in reducing symptoms of angina, although the extent of this effect and place in therapy is unclear (47021,47025,96442,96443,96445). Analyses of the available clinical research, involving up to 109 studies with 11,973 patients, show that compound danshen dripping pill, 216-270 mg, taken as 8-10 pills, three times daily for 1-6 months, is more effective than isosorbide dinitrate taken as 5-20 mg three times daily in improving the symptoms and ECG parameters associated with angina (96442,96445). Another analysis involving 17 studies with 1,433 patients found that danshen injection as an adjunct to standard treatment options was more effective in improving symptoms of angina and ECG parameters when compared with standard treatment alone. However, details on the dose of danshen injection and the standard treatments used in the reviewed studies were not provided (96443). The low quality and high heterogeneity of the reviewed studies limit the validity of these findings. Also, the optimal dose and optimal form of danshen for treating angina has not been identified. Additionally, the effects of danshen alone are unclear. Salvianolate, a component of danshen, has been evaluated for the treatment of angina. A review of the available research shows that giving salvianolate as an intravenous infusion 250 mg in 250 mL dextrose daily for 10-14 days reduces angina severity and nitroglycerin tablet use in about 28% of people with stable angina. The patients most likely to respond are overweight, hypertensive, or experience at least 3 angina episodes per week (99069).
• Atopic dermatitis (eczema). Although there is interest in using oral danshen for eczema, there is insufficient reliable information about the clinical effects of danshen for this condition.
• Cancer. It is unclear if oral danshen is beneficial for cancer treatment. Details: A meta-analysis of 13 small, heterogenous clinical trials shows that taking various formulas containing danshen in combination with chemotherapy increases the odds of response and survival over 1-5 years when compared with chemotherapy alone. In patients with various types of cancer, including leukemia, and lung, liver, breast, colon, and gastric cancer, the odds of survival were increased by at least 1.7-fold (101976). It is unclear what other treatments these patients were receiving.
• Cirrhosis. It is unclear if oral or intravenous danshen are beneficial for cirrhosis. Details: A meta-analysis of results from low-quality clinical research, including 11 studies involving 1,086 patients, suggests that compound danshen injection or danshen injection 16-30 mL in conjunction with astragalus injection 10-30 mL daily for up to 90 days is superior to control in reducing liver function enzyme levels, increasing albumin levels, and reducing markers of fibrosis in adults with cirrhosis. However, the variability of treatments used as control, the wide range of outcomes assessed, and the significant heterogeneity between trials limits the validity of these findings (90662). Additionally, the effect of danshen injection alone is unclear.
• Coronary heart disease (CHD). Preliminary clinical research suggests that taking compound danshen dripping pills containing danshen extract, Panax notoginseng, and borneol may improve some cardiac symptoms, surrogate markers of cardiac function, and metabolic indices in patients with CHD. The effect of danshen alone is unclear. Details: A meta-analysis of the results of low-quality clinical research, including 10 studies involving 1,367 patients, shows that taking compound danshen dripping pills 240-270 mg as 10 tablets three times daily in combination with aspirin 25-100 mg daily for 4 weeks to 2 years reduces symptoms of CHD and pain when compared with aspirin alone in adults with CHD (96439). Also, meta-analyses of low-quality clinical research, including up to 19 studies, show that taking compound danshen dripping pills in combination with aspirin reduces total cholesterol, low-density lipoprotein (LDL) cholesterol, and triglyceride levels, as well as plasma viscosity and platelet aggregation, and increases high-density lipoprotein (HDL) cholesterol levels, when compared with aspirin alone in adults with CHD (96439,109369). The low quality and high heterogeneity of the reviewed studies limit the validity of these findings. A meta-analysis of randomized clinical trials in adults with CHD that require percutaneous coronary intervention (PCI) shows that taking compound danshen dripping pills three times daily for 1-6 months reduces the risk of recurrent angina by 80%, coronary restenosis by 71%, heart failure by 55%, and malignant arrhythmia by 47% when compared with usual treatment, although there was no reduction in the risk for acute myocardial infarction or sudden cardiac death. Taking compound danshen dripping pills also improved LDL cholesterol levels, but not HDL cholesterol or triglyceride levels (105516). The validity of this study is limited by an unreported dose of compound danshen dripping pills, unclear use of antiplatelet and other adjunctive therapies in the control group, and possible publication bias. A more recent large clinical trial in adults with CHD complicated with anxiety and depression who recently underwent PCI shows that taking compound danshen dripping pills 400 mg three times daily for three months improves quality of life, anxiety, angina symptoms, and surrogate biomarkers such as endothelin and high-sensitivity C-reactive protein compared with placebo (112398).
• Diabetes. Although there is interest in using oral danshen for diabetes, there is insufficient reliable information about the clinical effects of danshen for this condition.
• Diabetic foot ulcers. Although there is interest in using oral danshen for diabetic foot ulcers, there is insufficient reliable information about the clinical effects of danshen for this condition.
• Diabetic nephropathy. It is unclear if oral or intravenous danshen are beneficial for diabetic nephropathy. Details: A meta-analysis of up to 13 preliminary clinical trials in patients with early diabetic kidney disease shows that intravenous administration of danshen and Ligusticum striatum extract for 2-4 weeks, in combination with conventional medications such as angiotensin receptor blockers, alprostadil, benazepril, and others, modestly reduces urinary albumin and serum creatinine levels when compared with conventional medications alone (109380). The effects of oral danshen or intravenous danshen alone in patients with diabetic nephropathy are unclear.
• Diabetic retinopathy. Preliminary clinical research suggests that taking compound danshen dripping pills, containing danshen extract, Panax notoginseng, and borneol, may improve visual acuity and the severity of diabetic retinopathy. The effect of danshen alone is unclear. Details: Meta-analyses of available preliminary clinical research in adults with diabetic retinopathy, including up to 13 studies, show that taking compound danshen dripping pill at doses of 270-540 mg or ten pills three times daily improves retinal and choroid circulation, visual field, and visual acuity, and reduces the occurrence of microaneurysm and retinal hemorrhage when compared with placebo, control, or conventional treatment alone. However, the low quality and high heterogeneity of the reviewed studies limit the validity of these findings (96437,109376). Some clinical research shows that taking compound danshen dripping pill 5 mg three times daily for 6 months may be more effective than taking captopril 12.5 mg two or three times daily for reducing macular edema and the severity of retinopathy and improving vision (109372). Additional clinical research shows that higher doses of compound danshen dripping pill of 540-810 mg three times daily may be most effective in improving symptoms of diabetic retinopathy when compared with placebo (96444).
• Endometriosis. Preliminary clinical research suggests that taking danshen-containing herbal products with gonadotropin-releasing hormone agonist (GnRH-a) may improve postoperative management of endometriosis. The effect of danshen alone is unclear. Details: A meta-analysis of eight preliminary clinical trials shows that taking danshen-containing herbal products along with GnRH-a following surgery for endometriosis reduces the recurrence of endometriosis by 74% when compared with GnRH-a alone. Some research also suggests that danshen-containing products reduce symptoms such as abnormal vaginal bleeding and hot flashes and increase the pregnancy rate (109381).
• Heart failure. Oral danshen has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: A meta-analysis of small clinical trials in adults with heart failure shows taking a danshen decoction 400 to 1600 mL daily for 2 to 8 weeks in combination with conventional therapy improves some markers of cardiac function such as left ventricular ejection fraction, left ventricular end-diastolic dimension, left ventricular end-systolic diameter, and serological indicators such as brain natriuretic peptide, N-terminal pro-B type natriuretic peptide, and C-reactive protein when compared with conventional therapy alone (112397). Danshen comprised 75% of the herbs in the decoction and Tanxiang and Sha ren equally comprised the other 25%. It is unclear if these findings are due to danshen, other ingredients, or the combination. The moderate to low quality of the evidence limits the validity of these findings. All studies in this analysis were conducted in China which may limit generalizability to other geographic regions.
• Hepatitis. Although there is interest in using oral danshen for chronic hepatitis, there is insufficient reliable information about the clinical effects of danshen for this condition.
• Hyperlipidemia. It is unclear if oral or intravenous danshen are beneficial for hyperlipidemia. Details: Preliminary clinical research in adults with hyperlipidemia shows that taking lipid-lowering medication and injecting 1 mL of danshen into two of four possible acupuncture points daily for 30 days decreases total cholesterol, low-density lipoprotein (LDL) cholesterol, and triglycerides, and increases high-density lipoprotein (HDL) cholesterol. Improvements appear to occur in 90% of patients using danshen plus lipid-lowering medication, compared with only 44% of patients using lipid-lowering medication alone (47072). However, other preliminary clinical research shows that taking danshen extract 3 grams three times daily for 28 days leads to increases in total cholesterol and LDL cholesterol levels, with no change in HDL cholesterol levels, when compared with placebo in adults with hyperlipidemia and hypertension (96441).
• Hypertension. It is unclear if oral danshen is beneficial for hypertension. Details: Clinical research in adults with uncontrolled hypertension shows that taking a mixture of extracts of danshen 450 mg, rhodiola 40 mg, chrysanthemum 200 mg, and kudzu 200 mg twice daily for 12 weeks along with antihypertensive drugs does not increase response to treatment, defined as a sitting systolic blood pressure (SBP) less than 140 mmHg and/or sitting diastolic blood pressure (DBP) less than 90 mmHg OR achieving a reduction of more than 10 mmHg in SBP or more than 5 mmHg in DBP. However, taking this combination along with antihypertensive drugs increases the percentage of patients with a sitting SBP less than 140 mmHg and/or sitting DBP less than 90 mmHg by about 3.5-fold when compared with antihypertensive drugs alone (94396). However, other preliminary clinical research shows that taking danshen extract 3 grams three times daily for 28 days does not lower SBP or DBP when compared with placebo in adults with hyperlipidemia and hypertension (96441).
• Hypoparathyroidism. Intravenous danshen has only been evaluated in combination with other ingredients; its effect when used alone is unclear. The effect of oral danshen is unclear. Details: Preliminary clinical research in patients with postoperative hypoparathyroidism after a total thyroidectomy shows that intravenous danshen and the rhizome of Ligusticum chuanxiong 10 mL daily for one week reduces the time to recovery of parathyroid function by about 2 weeks, and results in increased serum parathyroid hormone and calcium levels over 6 months, when compared with conventional treatment including calcitriol and calcium gluconate. Also, there was a reduction in the number of patients with permanent hypoparathyroidism (109379).
• Intrauterine Adhesions. Intrauterine danshen has only been evaluated in combination with various oral ingredients; its effect when used alone is unclear. The effect of oral danshen is unclear. Details: Preliminary clinical research in patients with moderate to severe intrauterine adhesions shows that use of intrauterine danshen (Harbin Pharm Group Sanjing Pharmaceutical Co, Ltd.) 5 mL, along with oral Chinese medications for 6 months after adhesion resection and balloon uterine stent placement, may improve clinical efficacy when compared with a control group receiving hyaluronic acid and an intrauterine device (IUD). Clinical efficacy, defined as normal menstruation with at least a near normal intrauterine lining and normal or slightly reduced blood volume, was 89% after treatment with danshen, compared with 69% in the control group. Uterine re-adhesion after 3 months was also reduced. However, there was no difference in the 6-month follow-up pregnancy rate (109374).
• Kidney transplant. It is unclear if oral or intravenous danshen are beneficial following kidney transplantation. Details: Preliminary clinical research shows that injection with danshen 60 mL daily for 10 days in addition to conventional treatment improves urinary volume and creatinine clearance and reduces the incidence of renal function recovery after kidney transplantation when compared with conventional treatment alone. However, the risk of acute rejection does not seem to be affected (47019).
• Obesity. Although there is interest in using oral danshen for obesity, there is insufficient reliable information about the clinical effects of danshen for this condition.
• Oral submucous fibrosis. It is unclear if oral or intravenous danshen are beneficial for oral submucous fibroids. Details: A meta-analysis of 13 generally low-quality randomized controlled trials shows that danshen injection with corticosteroids, usually triamcinolone acetonide, improves symptoms of oral submucous fibrosis better than conventional corticosteroid treatment alone. Danshen modestly improved maximal mouth opening and moderately improved the oral mucosal lesion area and sensation of burning (101975). The effect of oral danshen is unclear.
• Pancreatitis. Although there is interest in using oral danshen for pancreatitis, there is insufficient reliable information about the clinical effects of danshen for this condition.
• Polycystic ovary syndrome (PCOS). It is unclear if oral danshen is beneficial for PCOS. Details: A meta-analysis of two preliminary clinical trials in patients with PCOS shows that taking danshen along with medication does not increase the pregnancy rate when compared with medication alone. However, these studies differed in their findings, with a 2.6-fold increase in pregnancy rate when compared with letrozole alone in one study and no increase when compared with cyproterone acetate in the other. Taking danshen may decrease fasting levels of glucose and insulin and improve levels of low-density lipoprotein (LDL) cholesterol, high-density lipoprotein (HDL) cholesterol, triglycerides, and reproductive hormones when compared with placebo or medications alone (109378). However, the number of clinical trials in each meta-analysis was small.
• Pre-eclampsia. It is unclear if intravenous or oral danshen is beneficial for pre-eclampsia. Details: Preliminary clinical research in patients with severe pre-eclampsia on bed rest shows that intravenous danshen 16 mL in combination with magnesium sulfate up to 30 grams daily for 7 days results in clinical improvements when compared with magnesium sulfate alone. Blood pressure reductions to below 150/100 mmHg and improvement in clinical symptoms occurred in 93% of patients, compared with 77% of those in the control group. There were also modest improvements in liver and kidney function indices (109382). The effect of oral danshen is unclear.
• Pregnancy-induced hypertension. It is unclear if intravenous or oral danshen is beneficial for pregnancy-induced hypertension. Details: Preliminary clinical research in patients with pregnancy-induced hypertension shows that intravenous danshen 10-20 mL in combination with magnesium sulfate 4-10 mL once daily for 10 days modestly reduces systolic and diastolic blood pressure, as well as 24-hour urinary protein levels, when compared with magnesium sulfate alone. Also, the number of patients with a reduction or elimination of clinical symptoms was increased (109373).
• Psoriasis. Although there is interest in using oral danshen for psoriasis, there is insufficient reliable information about the clinical effects of danshen for this condition.
• Stroke. Preliminary clinical research suggests that oral or intravenous danshen may be beneficial for reducing symptoms following a stroke. Details: Preliminary clinical research shows that taking danshen orally or intravenously, usually as composite products, or administering the constituent salvianolic acid intravenously, might produce some improvement in neurological deficits, sleep quality, and blood flow indices after acute ischemic stroke (15538,47002,47017,101978,109371,109377). In one study, compound danshen dripping pills prepared with Panax notoginseng, borneol, and extracts of danshen, 270 mg (10 pills) three times daily for 28 days was used (15538). Compound danshen 16 mL or 20 mL and danshen 30 mL injection have been used for up to 28 days, occasionally in combination with snake venom (15538,96436). Other research shows that danshen injection is not as effective as danhong injection, an extract of danshen and safflower, in improving neurological deficits after acute ischemic stroke; however, the clinical relevance of this finding in the context of standard treatments is unclear (96436).
• Unstable angina. Oral danshen has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: Preliminary clinical research in patients with unstable angina shows that taking danshen dripping pill 0.4 grams three times daily, alone or in combination with andrographis 0.2 grams three times daily, for 4 weeks modestly improves symptoms, although the combination of andrographis with danshen dripping pill was more effective than danshen dripping pill alone (109370).
• Venous Thromboembolism (VTE). Oral danshen has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: Preliminary clinical research in patients with multiple myeloma receiving treatment with thalidomide shows that taking compound danshen dripping pill, containing danshen extract, Panax notoginseng, and borneol, 108 mg (4 tablets) three times daily for 8 months is as effective as warfarin for preventing VTE. Compound danshen dripping pills and warfarin demonstrate equal efficacy in preventing thalidomide-induced elevations in D-dimer and fibrinogen levels after 3 months of prophylaxis (96440). The effects of danshen alone are unclear.
• Wound healing. Although there is interest in using oral danshen for wound healing, there is insufficient reliable information about the clinical effects of danshen for this purpose. More evidence is needed to rate danshen for these uses.

• Atopic dermatitis (eczema). Although there is interest in using oral dong quai for atopic dermatitis, there is insufficient reliable information about the clinical effects of dong quai for this condition.
• Chronic kidney disease (CKD). There is limited evidence on the use of dong quai in patients with CKD. Details: A large propensity score-matched observational study over 15 years in Taiwanese adults with CKD suggests that taking dong quai is associated with a 5.1% risk of end-stage renal disease (ESRD) and 38% risk of overall mortality when compared with 7% and 56%, respectively, in controls. Higher cumulative doses (i.e., 15 grams or more) and longer duration of exposure (i.e., > 60 days) are also associated with fewer ESRD events (112362). However, the interpretation of these findings is limited by the lack of exact dosage information and retrospective study design.
• Coronary heart disease (CHD). Intravenous dong quai has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: Preliminary clinical research in patients with CHD shows that injecting 20 mL of an intravenous solution containing dong quai, ginseng, and astragalus (Yi-qi Huo-xue Injection) daily for 2 weeks reduces the frequency and severity of angina episodes when compared with placebo. It also seems to increase exercise tolerance and improve left ventricular function when compared with placebo (33046). It is unclear if these benefits are due to dong quai, other ingredients, or the combination.
• Dysmenorrhea. Although there is interest in using oral dong quai for dysmenorrhea, there is insufficient reliable information about the clinical effects of dong quai for this condition.
• Hypertension. Although there is interest in using oral dong quai for hypertension, there is insufficient reliable information about the clinical effects of dong quai for this purpose.
• Idiopathic interstitial pneumonia. Oral dong quai has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: A meta-analysis of 17 studies conducted in China in patients with idiopathic interstitial pneumonia concludes that adding traditional Chinese medicine combinations containing dong quai root and astragalus root to treatment with conventional medicines improves pulmonary function index, six-minute walking distance, and the Borg scale of perceived exertion when compared with conventional treatment alone (103618). The included studies are of low quality, include a range of treatment durations from 1-12 months, and vary in the conventional medicines and Chinese herb combinations used. The doses of dong quai used were not stated.
• Infertility. Although there is interest in using oral dong quai for infertility, there is insufficient reliable information about the clinical effects of dong quai for this condition.
• Iron deficiency anemia. Although there is interest in using oral dong quai for iron deficiency anemia, there is insufficient reliable information about the clinical effects of dong quai for this condition.
• Menopausal symptoms. There is inconsistent and contradictory evidence about the effect of dong quai on menopausal symptoms. Benefits have only been seen when it is used in combination with other ingredients; its effect when used alone is unclear. Details: Some clinical research shows that taking dong quai, 1.5 grams three times daily for 24 weeks, does not affect menopausal symptoms (738). Other clinical research shows that dong quai improves menopausal symptoms when used in combination with other constituents. In one clinical trial, taking five chewable tablets of a specific combination of dong quai and chamomile (Climex) daily for 12 weeks reduced the frequency and severity of hot flushes when compared with placebo (48445). In another trial, taking a combination providing dong quai 75 mg, along with American ginseng, black cohosh, milk thistle, red clover, and vitex agnus-castus (Phyto-Female Complex) twice daily for 3 months reduces menopausal symptoms, including the number and intensity of hot flushes, the number of night sweats, and sleep quality (19552). Taking another combination product containing dong quai, burdock root, licorice root, motherwort, and Mexican wild yam root, 500 mg three times daily for 3 months, also reduces menopausal symptoms when compared with placebo (48522). It is unclear if the beneficial effects in these studies were due to dong quai, other ingredients, or a combination of ingredients.
• Migraine headache. Oral dong quai has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: Preliminary clinical research in patients with menstrual migraine shows that taking a combination of soy isoflavones 60 mg, dong quai 100 mg, and black cohosh 50 mg daily for 24 weeks reduces the frequency of attacks when compared with placebo (35797). It is unclear if this effect is due to dong quai, other ingredients, or the combination.
• Osteoporosis. Although there is interest in using oral dong quai for osteoporosis, there is insufficient reliable information about the clinical effects of dong quai for this condition.
• Peptic ulcers. Although there is interest in using oral dong quai for peptic ulcers, there is insufficient reliable information about the clinical effects of dong quai for this condition.
• Premature ejaculation. Topical dong quai has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: In one preliminary clinical trial in patients with premature ejaculation, a multi-ingredient cream preparation (SS Cream) containing dong quai, Panax ginseng root, Cistanches deserticola, Zanthoxyl species, Torlidis seed, clove flower, Asiasari root, cinnamon bark, and toad venom was applied to the glans penis 1 hour prior to intercourse and washed off immediately before intercourse. Patients using the cream had significantly improved ejaculatory latency when compared with placebo cream (2537). It is unclear if this effect is due to dong quai, other ingredients, or the combination.
• Premenstrual syndrome (PMS). Although there is interest in using oral dong quai for PMS, there is insufficient reliable information about the clinical effects of dong quai for this condition.
• Psoriasis. Although there is interest in using oral dong quai for psoriasis, there is insufficient reliable information about the clinical effects of dong quai for this condition.
• Pulmonary hypertension. Preliminary clinical research shows that intravenous dong quai may be effective in patients with pulmonary hypertension. Details: Some preliminary clinical research in patients with chronic obstructive pulmonary disease (COPD) and pulmonary hypertension shows that intravenous administration of 250 mL of a solution containing dong quai 25%, once daily for 5-10 days, reduces pulmonary arterial pressure and pulmonary vascular resistance when compared to baseline (48438,48442,48443). The validity of these findings is limited by the lack of comparator groups.
• Rheumatoid arthritis (RA). Although there is interest in using oral dong quai for RA, there is insufficient reliable information about the clinical effects of dong quai for this condition.
• Stroke. Preliminary evidence does not support the use of intravenous dong quai for acute ischemic stroke. Details: Preliminary clinical research in patients with acute ischemic stroke shows that administering 200 mL of a solution containing dong quai 25% intravenously daily for 20 days does not improve neurological symptoms when compared with dextran-40 (48483). More evidence is needed to rate dong quai for these uses.

• Dementia. Although there is interest in using oral poria mushroom for dementia, there is insufficient reliable information about the clinical effects of poria mushroom for this condition.
• Diabetes. Oral poria mushroom has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: A meta-analysis of generally small clinical trials in patients with type 2 diabetes shows that taking Chinese herbal medicine combinations containing poria mushroom for 2-24 weeks along with hypoglycemic medications modestly reduces fasting blood glucose and glycated hemoglobin levels when compared with control groups taking hypoglycemic agents only. There were also modest improvements in levels of triglycerides and low-density lipoprotein (LDL) cholesterol and in insulin sensitivity (111920). Given the large number of other ingredients in the available formulations, it is unclear if any beneficial effects are related to poria mushroom, other ingredients in the formulation, or their combination.
• Diarrhea. Although there is interest in using oral poria mushroom for diarrhea, there is insufficient reliable information about the clinical effects of poria mushroom for this condition.
• Endometriosis. Although there is interest in using oral poria mushroom for endometriosis, there is insufficient reliable information about the clinical effects of poria mushroom for this condition.
• Influenza. Oral poria mushroom has only been evaluated for influenza vaccine enhancement in combination with other ingredients; its effect when used alone is unclear. Details: Clinical research in healthy adults shows that taking a product containing poria mushroom extract, rosemary extract, and aloe gel powder twice daily for 28 days prior to and following an influenza vaccination does not affect upper respiratory tract illness symptoms, severity, duration, or medication-related use when compared with taking placebo (111921). It is unclear if this study was large enough to detect differences between groups. Also, the effect of poria mushroom itself on influenza vaccine enhancement is unclear.
• Tinnitus. Although there is interest in using oral poria mushroom for tinnitus, there is insufficient reliable information about the clinical effects of poria mushroom for this condition.

• Aplastic anemia. It is unclear if oral rehmannia is beneficial in patients with aplastic anemia. Details: A small clinical study in adults with aplastic anemia shows that taking rehmannia polysaccharide (dose unknown), in conjunction with stanozolol, increases the incidence of symptom remission by 45% when compared with stanozolol alone (70704).
• Atopic disease. Although there has been interest in using oral rehmannia for atopic disease, there is insufficient reliable information about the clinical effects of rehmannia for this purpose.
• Diabetes. Although there has been interest in using oral rehmannia for diabetes, there is insufficient reliable information about the clinical effects of rehmannia for this purpose.

Severity = Moderate •  Occurrence = Possible •  Level of Evidence = D Theoretically, danshen may increase the levels and clinical effects of drugs metabolized by CYP2E1.  Details In vitro research shows that various constituents of danshen inhibit the activity of CYP2E1 (94393). So far, this interaction has not been reported in humans.

CYTOCHROME P450 3A4 (CYP3A4) SUBSTRATES Interaction Rating = Moderate Be cautious with this combination. Severity = Moderate •  Occurrence = Possible •  Level of Evidence = B Danshen might alter the levels and clinical effects of drugs metabolized by CYP3A4.  Details 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% (17404,94390). However, a single dose of danshen has the opposite effect, increasing maximum concentrations of midazolam by 87% (94390).

DIGOXIN (Lanoxin) Interaction Rating = Major Do not take this combination. Severity = High •  Occurrence = Probable •  Level of Evidence = D Theoretically, using danshen with digoxin might increase the risk of adverse effects.  Details Danshen has structural and pharmacological similarities to cardiac glycosides (5884,6048,7311).

FEXOFENADINE (Allegra) Interaction Rating = Moderate Be cautious with this combination. Severity = Moderate •  Occurrence = Probable •  Level of Evidence = B Danshen might increase the levels and clinical effects of fexofenadine.  Details 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% (94391).

GLUCURONIDATED DRUGS Interaction Rating = Moderate Be cautious with this combination. Severity = Moderate •  Occurrence = Possible •  Level of Evidence = D Theoretically, danshen might affect the levels and clinical effects of drugs requiring glucuronidation.  Details 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 (109375). So far, this interaction has not been reported in humans.

MIDAZOLAM (Versed) Interaction Rating = Moderate Be cautious with this combination. Severity = Moderate •  Occurrence = Probable •  Level of Evidence = B Danshen might alter the levels and clinical effects of midazolam.  Details 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% (17404,94390). However, a single dose of danshen has the opposite effect, increasing maximum concentrations of midazolam by 87% (94390).

P-GLYCOPROTEIN SUBSTRATES Interaction Rating = Moderate Be cautious with this combination. Severity = Moderate •  Occurrence = Possible •  Level of Evidence = B Danshen might alter the levels of drugs cleared by p-glycoprotein.  Details 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% (94391).

ROSUVASTATIN (Crestor) Interaction Rating = Moderate Be cautious with this combination. Severity = High •  Occurrence = Possible •  Level of Evidence = D Theoretically, danshen might increase the levels and clinical effects of rosuvastatin.  Details 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 (94395). So far, this interaction has not been reported in humans.

WARFARIN (Coumadin) Interaction Rating = Moderate Be cautious with this combination. Severity = Moderate •  Occurrence = Possible •  Level of Evidence = B Theoretically, danshen may increase the risk of bleeding if used with warfarin.  Details 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 (611,612,2237,5883,5884). 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 (96438). These findings are consistent with animal research, which found no change in warfarin pharmacokinetics with the use of danshen (94388,94397,94399). 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 (105517). However, other research shows that danshen might increase the rate of absorption and decrease the elimination rate of warfarin (5884,6048,94398). 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 (105517). Danshen should be used cautiously in patients taking warfarin.

ANTICOAGULANT/ANTIPLATELET DRUGS Interaction Rating = Moderate Be cautious with this combination. Severity = Moderate •  Occurrence = Possible •  Level of Evidence = D Theoretically, dong quai may increase the risk of bleeding when used with anticoagulant or antiplatelet drugs; however, research is conflicting.  Details Animal studies suggest that dong quai has antithrombin activity and inhibits platelet aggregation due to its coumarin components (6048,10057,96137). Additionally, some case reports in humans suggest that dong quai can increase the anticoagulant effects of warfarin (3526,6048,23310,48439). However, clinical research in healthy adults shows that taking 1 gram of dong quai root daily for 3 weeks does not significantly inhibit platelet aggregation or cause bleeding (96137). Until more is known, use dong quai with caution in patients taking antiplatelet/anticoagulant drugs.

ESTROGENS Interaction Rating = Moderate Be cautious with this combination. Severity = Moderate •  Occurrence = Possible •  Level of Evidence = D Theoretically, dong quai may reduce the effects of estrogens.  Details Dong quai has estrogenic effects (6180,7860,15108,15535,48459). Theoretically, concomitant use of large amounts of dong quai might interfere with hormone replacement therapy due to competition for estrogen receptors.

WARFARIN (Coumadin) Interaction Rating = Major Do not take this combination. Severity = High •  Occurrence = Probable •  Level of Evidence = D Dong quai may increase the risk of bleeding when used with warfarin.  Details Case reports suggest that concomitant use of dong quai with warfarin can increase the anticoagulant effects of warfarin and increase the risk of bleeding (3526,6048,23310,48439). In one case, after 4 weeks of taking dong quai 565 mg once or twice daily, the international normalized ratio (INR) increased to 4.9. The INR normalized 4 weeks after discontinuation of dong quai (3526).

CYCLOPHOSPHAMIDE Interaction Rating = Moderate Be cautious with this combination. Severity = Moderate •  Occurrence = Probable •  Level of Evidence = D Theoretically, schisandra might increase the levels and clinical effects of cyclophosphamide.  Details In vitro research shows that schisandra increases the concentration of cyclophosphamide, likely through inhibition of cytochrome P450 3A4. After multiple doses of the schisandra constituents schisandrin A and schisantherin A, the maximum concentration of cyclophosphamide was increased by 7% and 75%, respectively, while the overall exposure to cyclophosphamide was increased by 29% and 301%, respectively (109636).

CYCLOSPORINE (Neoral, Sandimmune) Interaction Rating = Moderate Be cautious with this combination. Severity = Moderate •  Occurrence = Probable •  Level of Evidence = B Schisandra can increase the levels and clinical effects of cyclosporine.  Details A small observational study in children with aplastic anemia found that taking schisandra with cyclosporine increased cyclosporine trough levels by 93% without increasing the risk of adverse events. However, the dose of cyclosporine was reduced in 9% of children to maintain appropriate cyclosporine blood concentrations (109637).

CYTOCHROME P450 2C19 (CYP2C19) SUBSTRATES Interaction Rating = Moderate Be cautious with this combination. Severity = Moderate •  Occurrence = Probable •  Level of Evidence = D Theoretically, schisandra might increase the levels and clinical effects of CYP2C19 substrates.  Details In vitro research shows that schisandra inhibits CYP2C19, and animal research shows that schisandra increases the concentration of voriconazole, a CYP2C19 substrate (105566). Theoretically, schisandra may also inhibit the metabolism of other CYP2C19 substrates. This effect has not been reported in humans.

CYTOCHROME P450 2C9 (CYP2C9) SUBSTRATES Interaction Rating = Moderate Be cautious with this combination. Severity = Moderate •  Occurrence = Possible •  Level of Evidence = D Theoretically, schisandra might decrease the levels and clinical effects of CYP2C9 substrates.  Details In vitro and animal research suggests that schisandra induces CYP2C9 enzymes (14441). This effect has not been reported in humans.

CYTOCHROME P450 3A4 (CYP3A4) SUBSTRATES Interaction Rating = Moderate Be cautious with this combination. Severity = Moderate •  Occurrence = Probable •  Level of Evidence = D Schisandra can increase the levels and clinical effects of drugs metabolized by CYP3A4.  Details Most clinical and laboratory research shows that schisandra, administered either as a single dose or up to twice daily for 14 days, inhibits CYP3A4 and increases the concentration of CYP3A4 substrates such as cyclophosphamide, midazolam, tacrolimus, and talinolol (13220,17414,23717,91386,91388,91387,96631,105564,109636,109638,109639,109640,109641). Although one in vitro and animal study shows that schisandra may induce CYP3A4 metabolism (14441), this effect appears to be overpowered by schisandra's CYP3A4 inhibitory activity and has not been reported in humans.

MIDAZOLAM (Versed) Interaction Rating = Moderate Be cautious with this combination. Severity = Moderate •  Occurrence = Probable •  Level of Evidence = B Schisandra can increase the levels and clinical effects of midazolam.  Details A small pharmacokinetic study in healthy adults shows that taking schisandra extract (Hezheng Pharmaceutical Co.) containing deoxyschizandrin 33.75 mg twice daily for 8 days and a single dose of midazolam 15 mg on day 8 increases the overall exposure to midazolam by about 119%, increases the peak plasma level of midazolam by 86%, and decreases midazolam clearance by about 52%. This effect has been attributed to inhibition of CYP3A4 by schisandra (91388).

P-GLYCOPROTEIN SUBSTRATES Interaction Rating = Moderate Be cautious with this combination. Severity = Moderate •  Occurrence = Possible •  Level of Evidence = D Schisandra might increase the levels and clinical effects of P-glycoprotein substrates.  Details In vitro research shows that schisandra extracts and constituents such as schisandrin B inhibit P-glycoprotein mediated efflux in intestinal cells and in P-glycoprotein over-expressing cell lines (17414,105643,105644). Additionally, a small clinical study shows that schisandra increases the peak concentration and overall exposure to talinolol, a P-glycoprotein probe substrate (91386). Theoretically, schisandra might inhibit the efflux of other P-glycoprotein substrates.

SIROLIMUS (Rapamune) Interaction Rating = Moderate Be cautious with this combination. Severity = Moderate •  Occurrence = Probable •  Level of Evidence = B Schisandra can increase the levels and clinical effects of sirolimus.  Details A small pharmacokinetic study in healthy volunteers shows that taking 3 capsules of schisandra (Hezheng Pharmaceutical Company) containing a total of 33.75 mg deoxyschizandrin twice daily for 13 days and then taking a single dose of sirolimus 2 mg increases the overall exposure and peak level of sirolimus by two-fold. This effect is thought to be due to inhibition of cytochrome P450 3A4 by schisandra, as well as possible inhibition of the P-glycoprotein drug transporter (105643).

TACROLIMUS (Prograf) Interaction Rating = Moderate Be cautious with this combination. Severity = Moderate •  Occurrence = Probable •  Level of Evidence = B Schisandra can increase the levels and clinical effects of tacrolimus.  Details Clinical research in healthy children and adults, transplant patients, and patients with nephrotic syndrome and various rheumatic immunologic disorders shows that taking schisandra with tacrolimus increases tacrolimus peak levels by 183% to 268%, prolongs or delays time to peak tacrolimus concentrations, increases overall exposure to tacrolimus by 126% to 343%, and decreases tacrolimus clearance by 19% to 73% (17414,91387,15570,96631,105623,109638,109639,109640,109641,112889)(112890,112972,112973,112974). This effect is thought to be due to inhibition of P-glycoprotein drug transporter and CYP3A4 and CYP3A5 by schisandra (17414,96631,105623,105643,105644,112974). Some clinical and observational studies suggest that schisandra increases tacrolimus levels similarly in both expressors and non-expressors of CYP3A5, while other studies suggest it does so to a greater degree in CYP3A5 expressors than non-expressors (105623,109638,109639,109640,112889,112890,112973,112974). Animal research suggests that the greatest increase in tacrolimus levels occurs when schisandra is taken either concomitantly or up to 2 hours before tacrolimus (105564), and clinical and observational research in humans suggests that schisandra may increase whole blood levels of tacrolimus and decrease clearance of tacrolimus in a dose-dependent manner (109639,109640,112972).

TALINOLOL Interaction Rating = Moderate Be cautious with this combination. Severity = Moderate •  Occurrence = Probable •  Level of Evidence = B Schisandra can increase the levels and clinical effects of talinolol.  Details A small pharmacokinetic study in healthy volunteers shows that taking schisandra extract 300 mg twice daily for 14 days with a single dose of talinolol 100 mg on day 14 increases the peak talinolol level by 51% and the overall exposure to talinolol by 47%. This effect is thought to be due to the possible inhibition of cytochrome P450 3A4 and P-glycoprotein by schisandra (91386). tly.

VORICONAZOLE (Vfend) Interaction Rating = Moderate Be cautious with this combination. Severity = Moderate •  Occurrence = Possible •  Level of Evidence = D Theoretically, schisandra might increase the levels and clinical effects of voriconazole.  Details Animal research shows that oral schisandra given daily for 1 or 14 days increases levels of intravenously administered voriconazole, a cytochrome P450 (CYP) 2C19 substrate. This effect is thought to be due to inhibition of CYP2C19 by schisandra (105566). However, this interaction has not been reported in humans.

WARFARIN (Coumadin) Interaction Rating = Moderate Be cautious with this combination. Severity = High •  Occurrence = Possible •  Level of Evidence = D Theoretically, schisandra might decrease the levels and clinical effects of warfarin.  Details Animal research suggests that oral schisandra extract, given daily for 6 days, reduces levels of intravenously administered warfarin. This effect might be due to the induction of cytochrome P450 (CYP) 2C9 metabolism by schisandra (14441). However, this interaction has not been reported in humans.

ANTIDIABETES DRUGS Interaction Rating = Moderate Be cautious with this combination. Severity = Moderate •  Occurrence = Possible •  Level of Evidence = D Theoretically, zizyphus might increase the risk of hypoglycemia when taken with antidiabetes drugs.  Details Animal research shows that zizyphus has hypoglycemic activity (87589,87591,87617,87637,87659,87671). However, a small clinical study shows that zizyphus fruit powder does not reduce fasting blood glucose levels in patients with type 2 diabetes (104507).

CNS DEPRESSANTS Interaction Rating = Moderate Be cautious with this combination. Severity = High •  Occurrence = Possible •  Level of Evidence = D Theoretically, zizyphus might cause additive sedative effects when taken with CNS depressants.  Details Some animal research has found that various parts of zizyphus have sedative effects (87572,87644,87646,87658). However, other animal research shows that zizyphus plant extract does not alter sleep parameters when used in combination with pentobarbital (93308).

CYTOCHROME P450 1A2 (CYP1A2) SUBSTRATES Interaction Rating = Moderate Be cautious with this combination. Severity = Moderate •  Occurrence = Possible •  Level of Evidence = D Theoretically, zizyphus might decrease the levels and clinical effects of drugs metabolized by CYP1A2.  Details Animal research shows that zizyphus induces CYP1A2 enzymes (93311). However, this effect has not been reported in humans.
