Below is general information about the safety of the known ingredients contained in the product Meno-Morphosis. Some ingredients may not be listed. This information does NOT represent a recommendation for or a test of this specific product as a whole.
POSSIBLY SAFE ...when used orally and appropriately. Black cohosh has been safely used in some studies lasting up to a year (15036,15158,17091,19553,35908); however, most studies have lasted only up to 6 months (141,4614,4620,7054,9437,9494,13143,13184,14330,14423)(14424,15037,15889,15893,35824,35852,35853,35858,35865,35897)(35902,35904,35946,35964,95525,103269). There is concern that black cohosh might cause liver damage in some patients. Several case reports link black cohosh to liver failure or autoimmune hepatitis (4383,10692,11906,12006,13144,14469,15160,16721,16722,16723)(16724,16725,16726,16727,35857,107906). However, the evidence that black cohosh causes liver damage is not conclusive (17085). Until more is known, monitor liver function in patients who take black cohosh.
PREGNANCY: POSSIBLY UNSAFE
when used orally in pregnant patients who are not at term.
Black cohosh might have hormonal effects and menstrual and uterine stimulant effects (15035). Theoretically, this might increase the risk of miscarriage; avoid using during pregnancy. There is insufficient reliable information available about the safety of black cohosh when used to induce labor.
LACTATION: POSSIBLY UNSAFE
when used orally.
Black cohosh might have hormonal effects. Theoretically, maternal intake of black cohosh might adversely affect a nursing child (15035). Until more is known, nursing patients should avoid taking black cohosh.
LIKELY SAFE ...when used in amounts commonly found in foods (12659,12660). Burdock root is commonly eaten as a vegetable (37422,92153,92154)
POSSIBLY SAFE ...when used topically, short-term. An emulsion containing burdock fruit extract 1.2% has been safely applied to the face twice daily for 4 weeks (37420). There is insufficient reliable information available about the safety of burdock when used orally in supplemental doses.
PREGNANCY AND LACTATION:
Insufficient reliable information available; avoid using.
POSSIBLY SAFE ...when used orally and appropriately. Dong quai has been used with apparent safety in a dose of 4.5 grams daily for 24 weeks, or in combination with other ingredients in doses of up to 150 mg daily for up to 6 months (19552,35797). ...when used intravenously as a 25% solution, in a dose of 200-250 mL daily for up to 20 days (48438,48442,48443,48483).
POSSIBLY UNSAFE ...when used orally in large amounts, long-term. Theoretically, long-term use of large amounts of dong quai could be harmful. Dong quai contains several constituents such as bergapten, safrole, and isosafrole that are considered carcinogenic (7162). There is insufficient reliable information available about the safety of dong quai when used topically.
PREGNANCY: POSSIBLY UNSAFE
when used orally.
Dong quai has uterine stimulant and relaxant effects (8142); theoretically, it could adversely affect pregnancy. Observational research has found that intake of An-Tai-Yin, an herbal combination product containing dong quai and parsley, during the first trimester is associated with an increased risk of congenital malformations of the musculoskeletal system, connective tissue, and eyes (15129).
LACTATION:
Insufficient reliable information available; avoid use.
LIKELY SAFE ...when used orally in amounts commonly found in foods. Licorice has Generally Recognized as Safe (GRAS) status in the US (4912).
POSSIBLY SAFE ...when licorice products that do not contain glycyrrhizin (deglycyrrhizinated licorice) are used orally and appropriately for medicinal purposes. Licorice flavonoid oil 300 mg daily for 16 weeks, and deglycyrrhizinated licorice products in doses of up to 4.5 grams daily for up to 16 weeks, have been used with apparent safety (6196,11312,11313,17727,100984,102960). ...when licorice products containing glycyrrhizin are used orally in low doses, short-term. Licorice extract 272 mg, containing glycyrrhizin 24.3 mg, has been used daily with apparent safety for 6 months (102961). A licorice extract 1000 mg, containing monoammonium glycyrrhizinate 240 mg, has been used daily with apparent safety for 12 weeks (110320). In addition, a syrup providing licorice extract 750 mg has been used twice daily with apparent safety for 5 days (104558). ...when applied topically. A gel containing 2% licorice root extract has been applied to the skin with apparent safety for up to 2 weeks. (59732). A mouth rinse containing 5% licorice extract has been used with apparent safety four times daily for up to one week (104564).
POSSIBLY UNSAFE ...when licorice products containing glycyrrhizin are used orally in large amounts for several weeks, or in smaller amounts for longer periods of time. The European Scientific Committee on Food recommends that a safe average daily intake of glycyrrhizin should not exceed 10 mg (108577). In otherwise healthy people, consuming glycyrrhizin daily for several weeks or longer can cause severe adverse effects including pseudohyperaldosteronism, hypertensive crisis, hypokalemia, cardiac arrhythmias, and cardiac arrest. Doses of 20 grams or more of licorice products, containing at least 400 mg glycyrrhizin, are more likely to cause these effects; however, smaller amounts have also caused hypokalemia and associated symptoms when taken for months to years (781,3252,15590,15592,15594,15596,15597,15599,15600,16058)(59731,59740,59752,59785,59786,59787,59792,59795,59805,59811)(59816,59818,59820,59822,59826,59828,59849,59850,59851,59867)(59882,59885,59888,59889,59895,59900,59906,97213,110305). In patients with hypertension, cardiovascular or kidney conditions, or a high salt intake, as little as 5 grams of licorice product or 100 mg glycyrrhizin daily can cause severe adverse effects (15589,15593,15598,15600,59726).
PREGNANCY: UNSAFE
when used orally.
Licorice has abortifacient, estrogenic, and steroid effects. It can also cause uterine stimulation. Heavy consumption of licorice, equivalent to 500 mg of glycyrrhizin per week (about 250 grams of licorice per week), during pregnancy seems to increase the risk of delivery before gestational age of 38 weeks (7619,10618). Furthermore, high intake of glycyrrhizin, at least 500 mg per week, during pregnancy is associated with increased salivary cortisol levels in the child by the age of 8 years. This suggests that high intake of licorice during pregnancy may increase hypothalamic-pituitary-adrenocortical axis activity in the child (26434); avoid using.
LACTATION:
Insufficient reliable information available; avoid using.
POSSIBLY SAFE ...when used orally and appropriately. Motherwort extracts have been used with apparent safety at doses of 1200 mg daily for up to 28 days (94209) or 800 mg daily, in combination with Lactiplantibacillus plantarum, for up to 12 weeks (115049)....when administered intramuscularly, short-term. One or more intramuscular injections have been used with apparent safety in total combined doses of 40-200 mg over 48 hours or less to prevent and/or stop postpartum bleeding (94203,101890,101891,101892). Post-marketing surveillance of over 8000 females found that a specific motherwort product (Chengdu No 1 Pharma Company Ltd) has been used without significant adverse effects for a duration of 48 hours or less (104855) ...when administered by intrauterine injection, short-term. Post-marketing surveillance of over 1800 patients found that a specific motherwort product (Chengdu No 1 Pharma Company Ltd) has been used without significant adverse effects for a duration of 48 hours or less (104855).
PREGNANCY: LIKELY UNSAFE
when used orally or by injection.
Alkaloids present in motherwort have uterine stimulant effects (4,12,19).
LACTATION:
Insufficient reliable information available; avoid using.
LIKELY SAFE ...when the fruit extract is used orally and appropriately, short-term. Vitex agnus-castus fruit extract has been used safely in studies at doses up to 40 mg daily, for up to 3 months (7055,7076,7077,7078,7079,12207,13393,15065,90617,90618,96435). There is insufficient reliable information available about the safety of vitex agnus-castus seeds when used orally or topically.
PREGNANCY AND LACTATION: POSSIBLY UNSAFE
when used orally.
Theoretically, the hormonal effects of vitex agnus-castus might adversely affect pregnancy or lactation (10979,11456,13393,109439). Animal research shows that taking vitex agnus-castus fruit extract when planning to become pregnant or during pregnancy may increase the risk of infertility, low fetal body weight, abortion, and stillbirth (109439); avoid using.
Below is general information about the interactions of the known ingredients contained in the product Meno-Morphosis. Some ingredients may not be listed. This information does NOT represent a recommendation for or a test of this specific product as a whole.
Taking black cohosh with atorvastatin might increase the risk for elevated liver function tests.
 Details
In one case report, a patient taking atorvastatin (Lipitor) developed significantly elevated liver function enzymes after starting black cohosh 100 mg four times daily. Liver enzymes returned to normal when black cohosh was discontinued (16725). It is unclear whether the elevated liver enzymes were due to black cohosh itself or an interaction between atorvastatin and black cohosh.
|
Theoretically, black cohosh may reduce the clinical effects of cisplatin.
Details
Animal research suggests that black cohosh might decrease the cytotoxic effect of cisplatin on breast cancer cells (13101).
|
Some research suggests that black cohosh might inhibit CYP2D6, but there is conflicting evidence.
Details
Some clinical research suggests that black cohosh might modestly inhibit CYP2D6 and increase levels of drugs metabolized by this enzyme (13536). However, contradictory clinical research shows a specific black cohosh product (Remifemin, Enzymatic Therapy) 40 mg twice daily does not significantly inhibit metabolism of a CYP2D6 substrate in healthy study volunteers (16848). Until more is known, use black cohosh cautiously in patients taking drugs metabolized by CYP2D6.
|
Theoretically, black cohosh may alter the effects of estrogen therapy.
Details
|
Theoretically, taking black cohosh with hepatotoxic drugs may increase the risk of liver damage.
Details
|
Black cohosh may inhibit one form of OATP, OATP2B1, which could reduce the bioavailability and clinical effects of OATP2B1 substrates.
Details
In vitro research shows that black cohosh modestly inhibits OATP2B1 (35450). OATPs are expressed in the small intestine and liver and are responsible for the uptake of drugs and other compounds into the body. Inhibition of OATP may reduce the bioavailability of oral drugs that are substrates of OATP.
|
Theoretically, taking burdock with anticoagulant or antiplatelet drugs might increase the risk of bleeding.
Details
In vitro research shows that lignans from burdock reduce rabbit platelet aggregation by inhibiting platelet activating factor (12619). This interaction has not been reported in humans. |
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.
|
Theoretically, dong quai may reduce the effects of estrogens.
Details
|
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).
|
Theoretically, licorice might reduce the effects of antihypertensive drugs.
Details
|
Theoretically, licorice might reduce the effects of cisplatin.
Details
In animal research, licorice diminished the therapeutic efficacy of cisplatin (59763).
|
Theoretically, concomitant use of licorice and corticosteroids might increase the side effects of corticosteroids.
Details
Case reports suggest that concomitant use of licorice and oral corticosteroids, such as hydrocortisone, can potentiate the duration of activity and increase blood levels of corticosteroids (3252,12672,20040,20042,48429,59756). Additionally, in one case report, a patient with neurogenic orthostatic hypertension stabilized on fludrocortisone 0.1 mg twice daily developed pseudohyperaldosteronism after recent consumption of large amounts of black licorice (108568).
|
Theoretically, licorice might decrease the levels and clinical effects of CYP1A2 substrates.
Details
In vitro research shows that licorice induces CYP1A2 enzymes (111404).
|
Theoretically, licorice might increase levels of drugs metabolized by CYP2B6.
Details
In vitro research shows that licorice extract and glabridin, a licorice constituent, inhibit CYP2B6 isoenzymes (10300,94822). Licorice extract from the species G. uralensis seems to inhibit CYP2B6 isoenzymes to a greater degree than G. glabra extract in vitro (94822). Theoretically, these species of licorice might increase levels of drugs metabolized by CYP2B6; however, these interactions have not yet been reported in humans.
|
Theoretically, licorice might increase levels of drugs metabolized by CYP2C19.
Details
In vitro, licorice extracts from the species G. glabra and G. uralensis inhibit CYP2C19 isoenzymes in vitro (94822). Theoretically, these species of licorice might increase levels of drugs metabolized by CYP2C19; however, this interaction has not yet been reported in humans.
|
Theoretically, licorice might increase levels of drugs metabolized by CYP2C8.
Details
In vitro, licorice extract from the species G. glabra and G. uralensis inhibits CYP2C8 isoenzymes (94822). Theoretically, these species of licorice might increase levels of drugs metabolized by CYP2C8; however, this interaction has not yet been reported in humans.
|
Theoretically, licorice might increase or decrease levels of drugs metabolized by CYP2C9.
Details
There is conflicting evidence about the effect of licorice on CYP2C9 enzyme activity. In vitro research shows that extracts from the licorice species G. glabra and G. uralensis moderately inhibit CYP2C9 isoenzymes (10300,94822). However, evidence from an animal model shows that licorice extract from the species G. uralensis can induce hepatic CYP2C9 activity (14441). Until more is known, licorice should be used cautiously in people taking CYP2C9 substrates.
|
Theoretically, licorice might increase or decrease levels of drugs metabolized by CYP3A4.
Details
Pharmacokinetic research shows that the licorice constituent glycyrrhizin, taken in a dosage of 150 mg orally twice daily for 14 days, modestly decreases the area under the concentration-time curve of midazolam by about 20%. Midazolam is a substrate of CYP3A4, suggesting that glycyrrhizin modestly induces CYP3A4 activity (59808). Animal research also shows that licorice extract from the species G. uralensis induces CYP3A4 activity (14441). However, licorice extract from G. glabra species appear to inhibit CYP3A4-induced metabolism of testosterone in vitro. It is thought that the G. glabra inhibits CYP3A4 due to its constituent glabridin, which is a moderate CYP3A4 inhibitor in vitro and not present in other licorice species (10300,94822). Until more is known, licorice should be used cautiously in people taking CYP3A4 substrates.
|
Theoretically, concomitant use of licorice with digoxin might increase the risk of cardiac toxicity.
Details
Overuse or misuse of licorice with cardiac glycoside therapy might increase the risk of cardiac toxicity due to potassium loss (10393).
|
Theoretically, concomitant use of licorice with diuretic drugs might increase the risk of hypokalemia.
Details
Overuse of licorice might compound diuretic-induced potassium loss (10393,20045,20046,59812). In one case report, a 72-year-old male with a past medical history of hypertension, type 2 diabetes, hyperlipidemia, arrhythmia, stroke, and hepatic dysfunction was hospitalized with severe hypokalemia and uncontrolled hypertension due to pseudohyperaldosteronism. This was thought to be provoked by concomitant daily consumption of a product containing 225 mg of glycyrrhizin, a constituent of licorice, and hydrochlorothiazide 12.5 mg for 1 month (108577).
|
Theoretically, licorice might increase or decrease the effects of estrogen therapy.
Details
|
Theoretically, loop diuretics might increase the mineralocorticoid effects of licorice.
Details
Theoretically, loop diuretics might enhance the mineralocorticoid effects of licorice by inhibiting the enzyme that converts cortisol to cortisone; however, bumetanide (Bumex) does not appear to have this effect (3255).
|
Theoretically, licorice might increase levels of methotrexate.
Details
Animal research suggests that intravenous administration of glycyrrhizin, a licorice constituent, and high-dose methotrexate may delay methotrexate excretion and increase systemic exposure, leading to transient elevations in liver enzymes and total bilirubin (108570). This interaction has not yet been reported in humans.
|
Theoretically, licorice might decrease levels of midazolam.
Details
In humans, the licorice constituent glycyrrhizin appears to moderately induce the metabolism of midazolam (59808). This is likely due to induction of cytochrome P450 3A4 by licorice. Until more is known, licorice should be used cautiously in people taking midazolam.
|
Theoretically, licorice might decrease the absorption of P-glycoprotein substrates.
Details
In vitro research shows that licorice can increase P-glycoprotein activity (104561).
|
Theoretically, licorice might decrease plasma levels and clinical effects of paclitaxel.
Details
Multiple doses of licorice taken concomitantly with paclitaxel might reduce the effectiveness of paclitaxel. Animal research shows that licorice 3 grams/kg given orally for 14 days before intravenous administration of paclitaxel decreases the exposure to paclitaxel and increases its clearance. Theoretically, this occurs because licorice induces cytochrome P450 3A4 enzymes, which metabolize paclitaxel. Notably, a single dose of licorice did not affect exposure or clearance of paclitaxel (102959).
|
Theoretically, licorice might decrease plasma levels and clinical effects of warfarin.
Details
Licorice seems to increase metabolism and decrease levels of warfarin in animal models. This is likely due to induction of cytochrome P450 2C9 (CYP2C9) metabolism by licorice (14441). Advise patients taking warfarin to avoid taking licorice.
|
Theoretically, taking motherwort concomitantly with other CNS depressants may increase the risk of sedation.
Details
|
Theoretically, vitex agnus-castus could interfere with the activity of antipsychotic drugs.
Details
|
Theoretically, vitex agnus-castus could interfere with oral contraceptives.
Details
|
Theoretically, vitex agnus-castus could interfere with dopamine agonists.
Details
Vitex agnus-castus might potentiate the actions of dopaminergic agonists due to possible dopaminergic effects (10122).
|
Theoretically, vitex agnus-castus could interfere with the activity of estrogens.
Details
|
Theoretically, dopaminergic effects of vitex agnus-castus could interfere with metoclopramide.

Below is general information about the adverse effects of the known ingredients contained in the product Meno-Morphosis. Some ingredients may not be listed. This information does NOT represent a recommendation for or a test of this specific product as a whole.
General
...Orally, black cohosh is generally well tolerated when used in typical doses.
Most Common Adverse Effects:
Orally: Breast tenderness, dizziness, gastrointestinal upset, headache, irritability, rash, tiredness.
Serious Adverse Effects (Rare):
Orally: Endometrial hyperplasia and hepatotoxicity, although data are conflicting for both.
Cardiovascular
...A single case of reversible bradycardia has been reported for a 59-year-old female who took one tablet of a specific black cohosh product (Remifemin, Schaper & Brümmer) daily for 2 weeks.
The adverse event was considered probably related to black cohosh use, although the exact mechanism by which black cohosh exerted this effect was unclear (35920).
There has been concern that, if black cohosh has estrogen-like effects, it could also potentially cause estrogen-like side effects including increased risk for thromboembolism and cardiovascular disease. These outcomes have not been specifically assessed in long-term trials; however, some research shows that a specific black cohosh extract (CimiPure, PureWorld) does not significantly affect surrogate markers for thromboembolism and cardiovascular risk such as fibrinogen, cholesterol, triglycerides, glucose, or insulin levels compared to placebo (16850).
Dermatologic ...Black cohosh has been associated with skin irritation and rashes (7054,10987,14330,15889,35853). A case report describes a patient who developed cutaneous pseudolymphoma 6 months after starting a specific black cohosh extract (Remifemin). Symptoms resolved within 12 weeks of discontinuing black cohosh (15890).
Gastrointestinal ...Orally, black cohosh can commonly cause gastrointestinal upset (4383,4615,4616,10988,13184,35824,35853,35965,103269,111714). Constipation and indigestion have also been reported (7054,35852).
Genitourinary
...Orally, black cohosh, including the specific black cohosh product Remifemin, may cause vaginal bleeding and breast tenderness in some postmenopausal patients (15889,35824).
However, the frequency of these events seems to be less than that of tibolone, a prescription hormone medication used to treat symptoms of menopause (15889,35904).
Due to the potential estrogen-like effects, there is concern that black cohosh might increase the risk of endometrial hyperplasia. However, a specific black cohosh extract CR BNO 1055 (Klimadynon/Menofem, Bionorica AG) does not appear to cause endometrial hyperplasia. Clinical research in postmenopausal adults shows that taking 40 mg daily of this extract for 12 weeks does not significantly increase superficial cells when compared with placebo, and causes significantly fewer superficial cells when compared with conjugated estrogens (Premarin) (14330). Additional clinical research shows that taking 40 mg daily of this extract for a year does not increase the risk of endometrial hyperplasia or endometrial thickening in postmenopausal adults (15036). Another specific combination product containing black cohosh extract plus St. John's wort (Gynoplus, Jin-Yang Pharm) also does not significantly increase superficial cells compared to placebo after 12 weeks of treatment (15893). Some patients taking tamoxifen plus black cohosh have experienced endometrial hyperplasia and vaginal bleeding. However, these effects are more likely due to tamoxifen than black cohosh (7054).
Hepatic
...There is concern that black cohosh might cause liver disease, hepatotoxicity, or hepatitis.
Adverse effects on the liver have not been documented in clinical studies. However, multiple case reports of liver toxicity, hepatitis, and abnormal liver function have been described in females taking black cohosh products alone or in combination with other herbs or drugs. In some cases, patients developed liver failure and required immediate liver transplantation (4383,10692,11909,12006,13144,14469,15160,16721,16722,16723) (16724,16727,35883,35888,35890,35895,89465,101592,107906). In one case, a female developed autoimmune hepatitis after 3 weeks of taking black cohosh. Symptoms resolved 2 weeks after discontinuing black cohosh (11906). In at least three cases, females have developed elevated liver enzymes and symptoms of hepatotoxicity after taking black cohosh products. Symptoms resolved and liver enzymes normalized within a week of discontinuing black cohosh (16725,16726). Analysis of two liver biopsies suggests that hepatotoxicity associated with black cohosh use results from the accumulation of 4HNE protein adducts in the cytoplasm of liver cells, which promotes the migration of lymphocytes to the affected area and induces an autoimmune response leading to troxis necrosis (89469).
However, many of these cases are poorly documented. Causality is possible based on some reports; however, other reports do not indicate that black cohosh is the probable cause of the events (15891,15892,16722,16723,16727,89465). Hepatitis can occur with no identifiable cause, raising the possibility that black cohosh and hepatitis might have been coincidental in some cases. Also, plant misidentification can occur, resulting in accidental substitution of a hepatotoxic plant (11910). Therefore, some experts argue that these cases do not provide conclusive evidence that black cohosh is responsible for liver disease (17085,35882,111634). Nonetheless, some countries require cautionary labeling on black cohosh products suggesting a risk of liver toxicity. The United States Pharmacopeia also recommends cautionary labeling on black cohosh products (16722). Until more is known about this potential risk, consider monitoring liver function in patients who take black cohosh.
Musculoskeletal
...One patient treated with black cohosh in a clinical trial discontinued treatment due to edema and arthralgia (35897).
Black cohosh has been linked to asthenia and muscle damage in one case. A 54-year-old female experienced asthenia with elevated creatinine phosphokinase (CPK) and lactate dehydrogenase (LDH) levels while taking black cohosh. The patient had taken a specific black cohosh extract (Remifemin) for 1 year, discontinued it for 2 months, restarted it, and then experienced symptoms 2 months later. Symptoms began to resolve 10 days after discontinuing black cohosh (14299).
Neurologic/CNS
...Orally, black cohosh may cause headache, dizziness, or tiredness (35852,35886).
There is one case report of seizures in a female who used black cohosh, evening primrose oil, and chasteberry (10988).
Also, there has been a case report of severe complications, including seizures, renal failure, and respiratory distress, in an infant whose mother was given an unknown dose of black cohosh and blue cohosh at 42 weeks gestation to induce labor (1122,9492,9493). However, this adverse effect may have been attributable to blue cohosh.
In another case report, orobuccolingual dyskinesia, including tongue-biting, eating difficulties, and speech problems, was reported in a 46-year-old female who took two tablets containing black cohosh 20 mg and Panax ginseng 50 mg daily for 15 months. The patient's condition improved after stopping treatment with the herbs and taking clonazepam 2 mg daily with baclofen 40 mg daily (89735).
Ocular/Otic ...There is some concern that black cohosh might increase the risk of retinal vein thrombosis due to its estrogenic activity. In one case, a patient with protein S deficiency and systemic lupus erythematosus (SLE) experienced retinal vein thrombosis 3 days after taking a combination product containing black cohosh 250 mg, red clover 250 mg, dong quai 100 mg, and wild yam 276 mg (13155). It is unclear if this event was due to black cohosh, other ingredients, the combination, or another factor.
Oncologic ...There is some concern that black cohosh may affect hormone-sensitive cancers, such as some types of breast or uterine cancer, due to its potential estrogenic effects. However, evidence from a cohort study suggests that regular use of black cohosh is not associated with the risk of breast or endometrial cancer (17412,111634).
Psychiatric ...A 36-year-old female with a 15-year history of depression developed mania with psychotic and mixed features after taking a black cohosh extract 40 mg daily. The patient gradually recovered after stopping black cohosh and receiving treatment with antipsychotics (104517).
Pulmonary/Respiratory ...There has been a case report of severe complications, including seizures, renal failure, and respiratory distress, in an infant whose mother was given an unknown dose of black cohosh and blue cohosh at 42 weeks gestation to induce labor (1122,9492,9493). However, this adverse effect may have been attributable to blue cohosh.
Renal ...There has been a case report of severe complications, including seizures, renal failure, and respiratory distress, in an infant whose mother was given an unknown dose of black cohosh and blue cohosh at 42 weeks gestation to induce labor (1122,9492,9493). However, this adverse effect may have been attributable to blue cohosh.
Other ...While rare, weight gain has been reported in some patients taking black cohosh. However, in most cases the causality could not be established. A review of the literature, including published case reports, spontaneous reports to adverse event databases, and clinical trials, suggests that black cohosh does not cause weight gain (107907).
General
...Orally, burdock is well tolerated when consumed as a food.
Although a thorough evaluation of safety outcomes is lacking, there has been long-standing historical use of burdock with few noted adverse effects.
Serious Adverse Effects (Rare):
All ROAs: Allergic reactions, including contact dermatitis and anaphylaxis.
Dermatologic ...Contact dermatitis has been reported secondary to burdock, especially after prolonged use of the root oil (37422). There are cases of allergic dermatitis secondary to using burdock plasters. Two males and a 14 year-old female developed erythematous and vesicular, pruritic, and exudative reactions in areas corresponding to the application of burdock root plasters (12667). Reactions occurred up to 7 days after initial use. Patch testing was positive for burdock sensitivity in all three patients and was nonreactive in matched controls.
Hematologic ...In one case report, a 38-year-old female developed immune-mediated thrombocytopenia after consuming a "cleansing" tea containing unknown amounts of burdock and yellow dock. The patient presented with bruising, mild weakness, and fatigue, which started 2-3 days after consuming the tea, and was found to have a platelet count of 5,000 per mcL. Symptoms resolved after platelet transfusion and treatment with oral dexamethasone (108971). It is unclear if these effects were caused by burdock, yellow dock, the combination, or other contributing factors.
Hepatic ...A case of idiosyncratic drug-induced liver disease (DILI) is reported in a 36-year-old female who presented with abdominal pain after 1 month of taking an herbal liver detox tea containing burdock and other ingredients. Remarkable laboratory values included elevated liver enzymes, alkaline phosphatase, and total bilirubin. The patient received a loading dose of N-acetylcysteine and was hospitalized for 12 days (112178). However, it is unclear if the adverse effect was due to burdock, other ingredients, or the combination.
Immunologic ...There is one case of anaphylactic shock secondary to eating boiled burdock. One hour after eating boiled burdock the patient presented with redness over the entire body and dyspnea. He was found to have low blood pressure and was treated with subcutaneous epinephrine 1 mg and intravenous lactated ringer's solution containing hydrocortisone 100 mg and dexamethasone 8 mg. The cause of anaphylactic shock was attributed to allergenicity to burdock based on positive skin prick test results. Previously, the patient had experienced urticaria after eating boiled burdock (12660).
Neurologic/CNS ...Anticholinergic reactions including dry mouth, dizziness, blurred vision, weakness, dilated pupils, inability to urinate, and bradycardia have been reported following the consumption of burdock products (12662,37421,37431,37434,37435). However, these anticholinergic reactions are believed result from contamination of burdock with belladonna alkaloids. Burdock itself does not contain atropine or other constituents that would be responsible for these reactions.
General
...Orally, dong quai is generally well-tolerated.
Most Common Adverse Effects:
Orally: Burping and flatulence.
Intravenously: Headache.
Cardiovascular ...Orally, dong quai might cause hypertension; according to one case report, a parent and breastfed infant experienced hypertension (195/85 mmHg and 115/69 mmHg, respectively) after the parent consumed a soup containing dong quai root (48428).
Dermatologic ...Dong quai contains psoralens that may cause photosensitivity and photodermatitis (10054,10057,48461).
Endocrine ...In a case report, a male developed gynecomastia after ingesting dong quai tablets (48504).
Gastrointestinal ...Orally, burping and gas may occur with dong quai (738).
Hematologic ...In one case report, a 55-year-old female with protein S deficiency and systemic lupus erythematosus (SLE) had temporary vision loss in the left eye from hemiretinal vein thrombosis three days after taking a phytoestrogen preparation containing dong quai 100 mg, black cohosh 250 mg, wild Mexican yam 276 mg, and red clover 250 mg (13155). It is unclear if dong quai contributed to this event.
Neurologic/CNS ...Dong quai given orally or by injection may be associated with headache (738,48438).
Oncologic ...Dong quai contains constituents that are carcinogenic; however, whether these constituents are present in concentrations large enough to cause cancer with long-term or high-dose use is unknown (7162).
Pulmonary/Respiratory ...A pharmacist experienced allergic asthma and rhinitis after occupational exposure to dong quai and other herbs (48435).
General
...Orally, licorice is generally well tolerated when used in amounts commonly found in foods.
It seems to be well tolerated when licorice products that do not contain glycyrrhizin (deglycyrrhizinated licorice) are used orally and appropriately for medicinal purposes or when used topically, short-term.
Most Common Adverse Effects:
Orally: Headache, nausea, and vomiting.
Topically: Contact dermatitis.
Intravenously: Diarrhea, itching, nausea, and rash.
Serious Adverse Effects (Rare):
Orally: Case reports have raised concerns about acute renal failure, cardiac arrest, cardiac arrhythmias, hypertension, hypokalemia, muscle weakness, paralysis, pseudohyperaldosteronism, and seizure associated with long-term use or large amounts of licorice containing glycyrrhizin.
Cardiovascular
...Orally, excessive licorice ingestion can lead to pseudohyperaldosteronism, which can precipitate cardiovascular complications such as hypertension and hypertensive crisis, ventricular fibrillation or tachycardia, sinus pause, and cardiac arrest.
These effects are due to the licorice constituent glycyrrhizin and usually occur when 20-30 grams or more of licorice product is consumed daily for several weeks (781,15590,15592,15594,15596,15597,15599,15600,16835,97213) (104563,108574,108576,110305,112234). In one case report, an 89-year-old female taking an herbal medicine containing licorice experienced a fatal arrhythmia secondary to licorice-induced hypokalemia. The patient presented to the hospital with recurrent syncope, weakness, and fatigue for 5 days after taking an herbal medicine containing licorice for 2 months. Upon admission to the hospital, the patient developed seizures, QT prolongation, and ventricular arrhythmia requiring multiple defibrillations. Laboratory tests confirmed hypokalemia and pseudohyperaldosteronism (112234).
However, people with cardiovascular or kidney conditions may be more sensitive, so these adverse events may occur with doses as low as 5 grams of licorice product or glycyrrhizin 100 mg daily (15589,15593,15598,15600,59726). A case report in a 54-year-old male suggests that malnutrition might increase the risk of severe adverse effects with excessive licorice consumption. This patient presented to the emergency room with cardiac arrest and ventricular fibrillation after excessive daily consumption of licorice for about 3 weeks. This caused pseudohyperaldosteronism and then hypokalemia, leading to cardiovascular manifestations. In spite of resuscitative treatment, the patient progressed to kidney failure, refused dialysis, and died shortly thereafter (103791).
Dermatologic
...There have been reports of contact allergy, resulting in an itchy reddish eruption, occurring in patients that applied cosmetic products containing oil-soluble licorice extracts (59912).
There have also been at least 3 cases of allergic contact dermatitis reported with the topical application of glycyrrhizin-containing products to damaged skin. In one case report, a 31-year-old female with acne presented with a 2-year history of pruritic erythematous-scaly plaques located predominantly on the face and neck after the use of a cosmetic product containing licorice root extract 1%. The patient had a positive skin patch test to licorice root extract, leading the clinicians to hypothesize that the use of benzoyl peroxide, a strong irritant, might have sensitized the patient to licorice (108578). Burning sensation, itching, redness, and scaling were reported rarely in patients applying a combination of licorice, calendula, and snail secretion filtrate to the face. The specific role of licorice is unclear (110322).
In rare cases, the glycyrrhizin constituent of licorice has caused rash and itching when administered intravenously (59712).
Endocrine
...Orally, excessive licorice ingestion can cause a syndrome of apparent mineralocorticoid excess, or pseudohyperaldosteronism, with sodium and water retention, increased urinary potassium loss, hypokalemia, and metabolic alkalosis due to its glycyrrhizin content (781,10619,15591,15592,15593,15594,15595,15596,15597,15598)(15600,16057,16835,25659,25660,25673,25719,26439,59818,59822)(59832,59864,91722,104563,108568,108574,110305,112234).
These metabolic abnormalities can lead to hypertension, edema, EKG changes, fatigue, syncope, arrhythmias, cardiac arrest, headache, lethargy, muscle weakness, dropped head syndrome (DHS), rhabdomyolysis, myoglobinuria, paralysis, encephalopathy, respiratory impairment, hyperparathyroidism, and acute kidney failure (10393,10619,15589,15590,15593,15594,15596,15597,15599)(15600,16057,16835,25660,25673,25719,26439,31562,59709,59716)(59720,59740,59787,59820,59826,59882,59889,59900,91722,97214,100522) (104563,108576,108577). These effects are most likely to occur when 20-30 grams of licorice products containing glycyrrhizin 400 mg or more is consumed daily for several weeks (781,15590,15592,15594,15596,15597,15599,15600,16835,108574). However, some people may be more sensitive, especially those with hypertension, diabetes, heart problems, or kidney problems (15589,15593,15598,15600,59726,108576,108577) and even low or moderate consumption of licorice may cause hypertensive crisis or hypertension in normotensive individuals (1372,97213). The use of certain medications with licorice may also increase the risk of these adverse effects (108568,108577). One case report determined that the use of large doses of licorice in an elderly female stabilized on fludrocortisone precipitated hypokalemia and hypertension, requiring inpatient treatment (108568). Another case report describes severe hypokalemia necessitating intensive care treatment due to co-ingestion of an oral glycyrrhizin-specific product and hydrochlorothiazide for 1 month (108577). Glycyrrhetinic acid has a long half-life, a large volume of distribution, and extensive enterohepatic recirculation. Therefore, it may take 1-2 weeks before hypokalemia resolves (781,15595,15596,15597,15600). Normalization of the renin-aldosterone axis and blood pressure can take up to several months (781,15595,108568). Treatment typically includes the discontinuation of licorice, oral and intravenous potassium supplementation, and short-term use of aldosterone antagonists, such as spironolactone (108574,108577).
Chewing tobacco flavored with licorice has also been associated with toxicity. Chewing licorice-flavored tobacco, drinking licorice tea, or ingesting large amounts of black licorice flavored jelly beans or lozenges has been associated with hypertension and suppressed renin and aldosterone levels (12671,12837,97214,97215,97217,108574). One case report suggests that taking a combination product containing about 100 mg of licorice and other ingredients (Jintan, Morishita Jintan Co.) for many decades may be associated with hypoaldosteronism, even up to 5 months after discontinuation of the product (100522). In another case report, licorice ingestion led to hyperprolactinemia in a female (59901). Licorice-associated hypercalcemia has also been noted in a case report (59766).
Gastrointestinal ...Nausea and vomiting have been reported rarely following oral use of deglycyrrhizinated licorice (25694,59871). Intravenously, the glycyrrhizin constituent of licorice has rarely caused gastric discomfort, diarrhea, or nausea (59712,59915).
Immunologic ...There have been reports of contact allergy, resulting in an itchy reddish eruption, occurring in patients that applied cosmetic products containing oil-soluble licorice extracts (59912). There have also been at least 3 cases of allergic contact dermatitis reported with the topical application of glycyrrhizin-containing products to damaged skin. In one case report, a 31-year-old female with acne presented with a 2-year history of pruritic erythematous-scaly plaques located predominantly on the face and neck after the use of a cosmetic product containing licorice root extract 1%. The patient had a positive skin patch test to licorice root extract, leading the clinicians to hypothesize that the use of benzoyl peroxide, a strong irritant, might have sensitized the patient to licorice (108578).
Musculoskeletal ...In a case report, excessive glycyrrhizin-containing licorice consumption led to water retention and was thought to trigger neuropathy and carpal tunnel syndrome (59791).
Neurologic/CNS ...Orally, licorice containing larger amounts of glycyrrhizin may cause headaches. A healthy woman taking glycyrrhizin 380 mg daily for 2 weeks experienced a headache (59892). Intravenously, the glycyrrhizin constituent of licorice has rarely caused headaches or fatigue (59721). In a case report, licorice candy ingestion was associated with posterior reversible encephalopathy syndrome accompanied by a tonic-clonic seizure (97218).
Ocular/Otic ...Orally, consuming glycyrrhizin-containing licorice 114-909 grams has been associated with transient visual loss (59714).
Pulmonary/Respiratory ...Orally, large amounts of licorice might lead to pulmonary edema. In one case report, a 64-year old male consumed 1020 grams of black licorice (Hershey Twizzlers) containing glycyrrhizin 3.6 grams over 3 days, which resulted in pulmonary edema secondary to pseudohyperaldosteronism (31561). Intravenously, the glycyrrhizin constituent of licorice has caused cold or flu-like symptoms, although these events are not common (59712,59721).
General
...Orally or via intramuscular or intrauterine injection, motherwort appears to be generally well tolerated.
Most Common Adverse Effects:
Orally: Diarrhea, stomach irritation.
Topically: Contact dermatitis, photosensitivity.
Intramuscular / Intrauterine: Abdominal pain, erythema, eyelid edema, fever, nausea, pruritus, rash.
Dermatologic ...Motherwort leaves can cause contact dermatitis, and the oil may cause photosensitivity reactions (4). Intramuscularly and via intrauterine injection, mild erythema, rash, and pruritus have been reported (101892,104855).
Gastrointestinal ...Orally, use of motherwort in amounts greater than 3 grams can cause diarrhea and stomach irritation (12). Intramuscularly and via intrauterine injection, abdominal pain and nausea have been reported (104855).
Genitourinary ...Orally, use of motherwort in amounts greater than 3 grams can cause uterine bleeding (12).
Immunologic ...Motherwort can also cause allergic reactions in sensitive individuals (4). Intramuscularly and via intrauterine injection, transient fever and chills lasting less than 24 hours have been reported (104855).
Ocular/Otic ...Intramuscularly and via intrauterine injection, transient eyelid edema lasting less than 24 hours has been reported (104855).
General
...Orally, vitex agnus-castus is generally well tolerated.
Most Common Adverse Effects:
Orally: Diarrhea, fatigue, headache, insomnia, irregular menstruation, nausea, skin irritation, stomach pain, vomiting.
Dermatologic ...Orally, skin conditions such as itching, irritation, urticaria, rash, acne, eczema, and hair loss have been reported (7055,7076,7078,7079,12207,13393,15065,90617,90619,101981).
Gastrointestinal ...Orally, gastrointestinal upset or pain, diarrhea, and nausea and vomiting, have been reported (7079,12207,13393,15065,90620,101981,101982). In one clinical trial, a single patient reported persistent gastroenteritis while taking vitex agnus-castus (7076). Orally, development of a bezoar resulting in colonic obstruction is described in a 63-year-old male who consumed an unknown amount of vitex agnus-castus seeds (111752).
Genitourinary ...Orally, irregular or prolonged menstrual bleeding has been reported (7055,7079,12207,13393,15065,41489,41490,95326).
Hematologic ...Orally, nosebleed has been reported in a single patient in a clinical trial (7079).
Immunologic ...Orally, multiple abscesses have been reported in a single patient (7055).
