Insufficient reliable information available; avoid using.
POSSIBLY SAFE ...when used orally and appropriately, short-term. Coleus extract 500 mg daily has been used for up to 3 months without significant adverse effects (91885,100851). ...when used intravenously and appropriately, short-term. Intravenous forskolin, a constituent of coleus, seems to be safe when given at an appropriate rate of 0.5 mcg/kg/minute and increased at 15 minute intervals to 1.0, 2.0, and 3.0 mcg/kg/minute up to 1 hour (7278,7279). ...when used by inhalation and appropriately. Single-dose inhalation of forskolin powder 10 mg from a Spinhaler inhalator seems to be safe and well-tolerated (7281). ...when used ophthalmologically and appropriately. Coleus suspension eye drops (1%) have been safely used in clinical studies (7282,7283,7284,7402,7403,7405).
POSSIBLY UNSAFE ...when used orally in higher doses. Although coleus extracts have been used with apparent safety in doses up to 1.4 grams daily for 2 months (91884), taking coleus extract in doses exceeding 500 mg daily has been associated with an increased incidence of adverse effects, which are primarily gastrointestinal (100851).
PREGNANCY: POSSIBLY UNSAFE
when used orally.
Evidence from animal research suggests that high doses of coleus can inhibit embryo implantation and/or delay fetal development (25174); avoid using.
LACTATION:
Insufficient reliable information available; avoid using.
POSSIBLY SAFE ...when used orally and appropriately, short-term. Hawthorn preparations in doses of up to 1800 mg daily seem to be safe when used for up to 16 weeks. Although hawthorn might be safe for long-term use, current studies have not evaluated safety past 16 weeks (8279,8280,8281,10144,17203,104689). There is insufficient reliable information available about the safety of hawthorn when used topically.
PREGNANCY AND LACTATION:
Insufficient reliable information available; avoid using.
LIKELY SAFE ...when used orally in food amounts. The fruit is commonly used in foods (101151). There is insufficient reliable information available about the safety of Indian long pepper when used in medicinal amounts.

Theoretically, taking ashwagandha with antidiabetes drugs might increase the risk of hypoglycemia.
Details
|
Theoretically, taking ashwagandha with antihypertensive drugs might increase the risk of hypotension.
Details
Animal research suggests that ashwagandha might lower systolic and diastolic blood pressure (19279). Theoretically, ashwagandha might have additive effects when used with antihypertensive drugs and increase the risk of hypotension.
|
Theoretically, taking ashwagandha might increase the sedative effects of benzodiazepines.
Details
There is preliminary evidence that ashwagandha might have an additive effect with diazepam (Valium) and clonazepam (Klonopin) (3710). This may also occur with other benzodiazepines.
|
Theoretically, taking ashwagandha might increase the sedative effects of CNS depressants.
Details
Ashwagandha seems to have sedative effects. Theoretically, this may potentiate the effects of barbiturates, other sedatives, and anxiolytics (3710).
|
Theoretically, taking ashwagandha might decrease the effects of immunosuppressants.
Details
|
Ashwagandha might increase the effects and adverse effects of thyroid hormone.
Details
Concomitant use of ashwagandha with thyroid hormones may cause additive therapeutic and adverse effects. Preliminary clinical research and animal studies suggest that ashwagandha boosts thyroid hormone synthesis and secretion (19281,19282,97292). In one clinical study, ashwagandha increased triiodothyronine (T3) and thyroxine (T4) levels by 41.5% and 19.6%, respectively, and reduced serum TSH levels by 17.4% from baseline in adults with subclinical hypothyroidism (97292).
|
There is some evidence forskolin, a constituent of coleus, can inhibit platelet aggregation and adhesion (7410,7411,7412). Theoretically, concomitant use of coleus and anticoagulant or antiplatelet drugs might increase the risk of bruising and bleeding. Some anticoagulant and antiplatelet drugs include abciximab (ReoPro), anagrelide (Agrylin), antithrombin III (Thrombate III), ardeparin (Normiflo), cilostazol (Pletal), clopidogrel (Plavix), dalteparin (Fragmin), danaparoid (Orgaran), dicumarol, dipyridamole (Persantine), enoxaparin (Lovenox), eptifibatide (Integrilin), heparin, lepirudin (Refludan), tirofiban (Aggrastat), and warfarin (Coumadin).
|
Animal research shows that forskolin, a constituent of coleus, may lower blood pressure (7278,7279,44424,44431). Theoretically, combining coleus with antihypertensive drugs might cause additive blood pressure lowering effects and increase the risk of hypotension. Some antihypertensive drugs include captopril (Capoten), enalapril (Vasotec), losartan (Cozaar), valsartan (Diovan), diltiazem (Cardizem), Amlodipine (Norvasc), hydrochlorothiazide (HydroDIURIL), furosemide (Lasix), and many others.
|
Using forskolin, a constituent of coleus, with calcium channel blockers such as verapamil (Calan, Covera-HS, Verelan), nifedipine (Procardia), and diltiazem (Cardizem, Dilacor, Tiazac) might cause additive coronary vasodilatory effects (7278,7279).
|
Research on the effect of coleus on cytochrome P450 2C9 (CYP2C9) is conflicting. Some animal research shows that coleus extract can induce CYP2C9, while in vitro research shows that coleus can inhibit CYP2C9 (91891). Theoretically, taking coleus with drugs metabolized by CYP2C9 might affect drug levels and the risk of adverse effects. Until more is known, advise patients that taking coleus might increase or decrease levels of drugs metabolized by CYP2C9.
Details
Some drugs metabolized by CYP2C9 include celecoxib (Celebrex), diclofenac (Voltaren), fluvastatin (Lescol), glipizide (Glucotrol), ibuprofen (Advil, Motrin), irbesartan (Avapro), losartan (Cozaar), phenytoin (Dilantin), piroxicam (Feldene), tamoxifen (Nolvadex), tolbutamide (Tolinase), torsemide (Demadex), and S-warfarin (Coumadin).
|
In vitro research shows that coleus can activate the nuclear receptor, pregnane X receptor (PXR), which results in increased expression of CYP3A4 (44399,44412). Theoretically, coleus might induce CYP3A4 and decrease levels of drugs metabolized by this enzyme. Although the clinical significance of this is not known, use caution when considering concomitant use of coleus and other drugs affected by these enzymes. Drugs that might be affected include some calcium channel blockers (diltiazem, nicardipine, verapamil), chemotherapeutic agents (etoposide, paclitaxel, vinblastine, vincristine, vindesine), antifungals (ketoconazole, itraconazole), glucocorticoids, cisapride (Propulsid), alfentanil (Alfenta), fentanyl (Sublimaze), losartan (Cozaar), fluoxetine (Prozac), midazolam (Versed), omeprazole (Prilosec), ondansetron (Zofran), propranolol (Inderal), fexofenadine (Allegra), and numerous others.
|
Using forskolin, a constituent of coleus, with nitrates such as nitroglycerin (Nitro-Bid, Nitro-Dur, Nitrostat) and isosorbide (Imdur, Isordil, Sorbitrate) might cause additive coronary vasodilatory effects (7278,7279,44424).
|
Preliminary research assessing the effect of coleus on warfarin metabolism is conflicting. Animal research shows that coleus extract induces cytochrome P450 2C9 (CYP2C9) enzymes and increases metabolism of warfarin; however, in vitro research shows that coleus inhibits CYP2C9 enzymes and might reduce warfarin metabolism (91891). Until more is known, advise patients to use coleus cautiously or avoid it if they taking warfarin.
|
Theoretically, hawthorn may increase the risk of bleeding if used with anticoagulant or antiplatelet drugs.
Details
In vitro and animal research shows that hawthorn can inhibit platelet aggregation (95528,95529,95530,95531). However, its effect in humans is unclear. One observational study shows that patients taking hawthorn shortly before undergoing coronary artery bypass graft (CABG) surgery or valve replacement surgery have a 10% incidence of postoperative bleeding, compared with 1% in those who never consumed hawthorn extract (95527). However, clinical research shows that taking a specific preparation of dried hawthorn leaves and flowers (Crataesor, Soria Natural Lab) 800 mg three times daily for 15 days does not affect platelet aggregation or levels of thromboxane B2, the metabolite of thromboxane A2, in healthy humans (54664).

|
Theoretically, Indian long pepper might increase blood levels of carbamazepine.
Details
A small pharmacokinetic study in patients taking carbamazepine 300 mg or 500 mg twice daily shows that a single 20 mg dose of purified piperine, which is a constituent of Indian long pepper, increases carbamazepine levels. Piperine may increase absorption by increasing blood flow to the GI tract, increasing the surface area of the small intestine, or by cytochrome P450 3A4 (CYP3A4) inhibition in the gut wall. Absorption was significantly increased by 7-10 mcg/mL/hour. The time to eliminate carbamazepine was also increased by 4-8 hours. Although carbamazepine levels were increased, this did not appear to increase side effects (16833).

Below is general information about the adverse effects of the known ingredients contained in the product Cardana. 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, ashwagandha seems to be well-tolerated.
Topically, no adverse effects have been reported. However, a thorough evaluation of safety outcomes has not been conducted.
Most Common Adverse Effects:
Orally: Diarrhea, gastrointestinal upset, nausea, and vomiting. However, these adverse effects do not commonly occur with typical doses.
Serious Adverse Effects (Rare):
Orally: Some case reports raise concerns about acute liver failure, hepatic encephalopathy, and the need for liver transplantation with ashwagandha treatment.
Dermatologic ...Orally, dermatitis has been reported in three of 42 patients in a clinical trial (19276).
Endocrine ...A case report describes a 73-year-old female who had taken an ashwagandha root extract (unspecified dose) for 2 years to treat hypothyroidism which had been previously managed with levothyroxine. The patient was diagnosed with hyperthyroidism after presenting with supraventricular tachycardia, chest pain, tremor, dizziness, fatigue, irritability, hair thinning, and low thyroid stimulating hormone (TSH) levels. Hyperthyroidism resolved after discontinuing ashwagandha (108745).
Gastrointestinal ...Orally, large doses may cause gastrointestinal upset, diarrhea, and vomiting secondary to irritation of the mucous and serous membranes (3710). When taken orally, nausea and abdominal pain (19276,110490) and gastritis and flatulence (90651) have been reported.
Genitourinary ...In one case report, a 28-year-old male with a decrease in libido who was taking ashwagandha 5 grams daily over 10 days subsequently experienced burning, itching, and skin and mucous membrane discoloration of the penis, as well as an oval, dusky, eroded plaque (3 cm) with erythema on the glans penis and prepuce (32537).
Hepatic ...Orally, ashwagandha in doses of 154-1350 mg daily has played a role in several case reports of liver injury. In most of these cases, other causes of liver injury were excluded, and liver failure did not occur. Symptoms included jaundice, pruritus, malaise, fatigue, lethargy, weight loss, nausea, diarrhea, abdominal pain, stool discoloration, and dark urine. Symptom onset was typically 5-180 days from first intake, although in some cases onset occurred after more than 12 months of use (102686,107372,110490,110491,111533,111535,112111). Laboratory findings include elevated aspartate transaminase (AST), alanine transaminase (ALT), alkaline phosphatase, and serum bilirubin (112111). In most cases, liver enzymes normalized within 1-5 months after discontinuation of ashwagandha (102686,107372,110491,111535,112111). However, treatment with corticosteroids, lactulose, ornithine, ursodeoxycholic acid, and plasmapheresis, among other interventions, was required in one case (111533). Rarely, use of oral ashwagandha has been reported to cause hepatic encephalopathy and liver failure requiring liver transplantation (110490).
Neurologic/CNS ...Orally, ashwagandha has been reported to cause drowsiness (110492). Headache, neck pain, and blurry vision have been reported in a 47-year-old female taking ashwagandha, cannabis, and venlafaxine. Imaging over the course of multiple years and hospital admissions indicated numerous instances of intracranial hemorrhage and multifocal stenosis of intracranial arteries, likely secondary to reversible cerebral vasoconstriction syndrome (RCVS) (112113). It is unclear whether the RCVS and subsequent intracranial hemorrhages were precipitated by ashwagandha, cannabis, or venlafaxine.
General ...Orally, intravenously, ophthalmologically, and by inhalation, coleus seems to be well tolerated (7278,7279,7282,7283,7284). Orally, coleus extract may cause dose-related gastrointestinal effects, including diarrhea, loose stools, nausea, vomiting, or constipation (91885,100851). Intravenously, the coleus constituent, forskolin, can cause tachycardia, flushing, and hypotension (7279,44424,44431). Inhalation of forskolin may cause tremor, restlessness, and irritation of the respiratory tract (7281). Ophthalmologically, forskolin may cause stinging of the eyes and conjunctival hyperemia (7283).
Cardiovascular ...Intravenously, the coleus constituent, forskolin, can cause tachycardia, flushing and hypotension (7279,44424,44431).
Dermatologic ...Two cases of contact dermatitis have been reported following airborne exposure to coleus (44426,44418).
Gastrointestinal ...Orally, coleus can cause dose-related diarrhea and other gastrointestinal symptoms. Increased bowel movements and loose stools have been reported in 1 of 15 patients taking coleus extract in a clinical trial (91885). Some retrospective evidence reports about a 10% rate of gastrointestinal adverse effects from oral coleus use; 81% of these adverse effects were related to diarrhea. Other reported adverse effects which occurred at a much lower rate, include nausea, vomiting, and/or constipation. Gastrointestinal effects appear to be dose-related; those taking less than 250 mg of coleus extract did not report any diarrhea, while all patients taking 1000 mg of coleus extract reported diarrhea (100851).
Neurologic/CNS ...Inhalation of forskolin, a constituent of coleus, can cause tremor and restlessness (7281).
Ocular/Otic ...Ophthalmologically, forskolin, a constituent of coleus, can cause stinging of the eyes and conjunctival hyperemia (7283).
Pulmonary/Respiratory ...Inhalation of forskolin, a constituent of coleus, can cause throat and upper respiratory tract irritation, and mild to moderate cough (7281).
General
...Orally, hawthorn seems to be well tolerated when used appropriately.
Topically, no adverse effects have been reported, although a thorough evaluation of safety outcomes has not been conducted.
Serious Adverse Effects (Rare):
Orally: Multiorgan hypersensitivity reactions resulting in acute renal failure have been reported rarely.
Cardiovascular ...Orally, tachycardia (with facial pains) of uncertain relationship to hawthorn was reported in a multicenter clinical trial (54640).
