|
Theoretically, artichoke leaf extract may increase the risk of hypotension when taken with antihypertensive drugs.
Details
A meta-analysis of small clinical studies in patients with hypertension shows that taking artichoke can reduce systolic blood pressure by around 3 mmHg and diastolic blood pressure by around 2 mmHg when compared with placebo (105767).
|
Theoretically, artichoke might increase serum levels of drugs metabolized by CYP2B6.
Details
In vitro research shows that artichoke leaf extract inhibits CYP2B6 activity (97717). However, this interaction has not been reported in humans.
|

Details
In vitro research shows that artichoke leaf extract inhibits CYP2C19 activity (97717). However, this interaction has not been reported in humans.
|
Theoretically, taking boldo with anticoagulant/antiplatelet drugs might increase the risk of bleeding.
Details
Animal and in vitro research shows that boldine, a constituent of boldo, has antiplatelet activity (5191,36789). In one case report, an adult taking a combination of boldo and fenugreek with warfarin experienced an increase in international normalized ratio (INR); however, it is unclear if this effect was due to boldo, fenugreek, the combination, or another factor (5191).
|
Theoretically, taking boldo with hepatotoxic drugs might increase the risk of hepatic injury and disease.
Details
|
Theoretically, taking boldo with lithium might increase the levels and clinical effects of lithium.
Details
Boldo is believed to have diuretic effects (4). Theoretically, these diuretic effects might reduce the excretion of lithium. The dose of lithium might need to be decreased.
|
Taking boldo with tacrolimus may decrease the levels and clinical effects of tacrolimus, potentially increasing the risk of transplant rejection.
Details
In one case report, a patient with a long-term history of stable tacrolimus levels developed subtherapeutic levels after taking boldo 300 mg twice daily orally for several weeks. Tacrolimus levels returned to normal after discontinuing boldo. However, the mechanism of this interaction is unclear (92601).
|
Theoretically, carqueja might lower blood glucose levels (13585,13588) and might have additive effects when used with antidiabetes drugs. This might increase the risk of hypoglycemia in some patients. Monitor blood glucose levels closely. Some antidiabetes drugs include glimepiride (Amaryl), glyburide (DiaBeta, Glynase PresTab, Micronase), insulin, metformin (Glucophage), pioglitazone (Actos), rosiglitazone (Avandia), and others.
|
Theoretically, chanca piedra might increase the risk of bleeding when used concomitantly with anticoagulant/antiplatelet drugs.
Details
In vitro research suggests that methyl brevifolincarboxylate, a constituent isolated from chanca piedra, can inhibit platelet aggregation (41234). This effect has not been reported in humans.
|
Theoretically, concomitant use with antidiabetes drugs might affect glucose control and increase the risk of hypoglycemia.
Details
Animal research suggests that chanca piedra can have hypoglycemic effects (19,41226,41280,41305,41306,41307). However, a small clinical study in adults with diabetes shows that chanca piedra extract 25 grams orally daily for 1 week does not lower fasting or postprandial blood glucose levels (41186).
|
Theoretically, concomitant use of chanca piedra with antihypertensive drugs might have additive blood pressure lowering effects.
Details
|
Theoretically, concomitant use of chanca piedra with diuretics might increase diuresis.
Details
Some preliminary clinical research in adults with hypertension shows that chanca piedra has diuretic properties (3928). However, higher quality research in adults with kidney stones shows taking chanca piedra does not increase urine volume when compared with placebo (41202). Until more is known, use cautiously in patients taking diuretic drugs.

Below is general information about the adverse effects of the known ingredients contained in the product Amazon Liver Support. 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, artichoke extract seems to be well tolerated.
Most Common Adverse Effects:
Orally: Abdominal pain, diarrhea, flatulence, hunger, and nausea.
Topically: Contact dermatitis in sensitive individuals.
Serious Adverse Effects (Rare):
Orally: Anaphylaxis to artichoke inulin has been reported in individuals sensitive to inulin.
Topically: Chest tightness, cough, and dyspnea after occupational exposure in sensitive individuals.
Dermatologic
...Artichoke can cause an allergic reaction in some patients.
Patients sensitive to the Asteraceae/Compositae family may be at the greatest risk. Members of this family include ragweed, chrysanthemums, marigolds, daisies, and many other herbs. Topically, allergic contact dermatitis can occur with the use of artichoke. This has been attributed to the constituent cynaropicrin (11,52206,52226,52230). Redness in the face (11774) and sweating (91475) have been reported rarely following oral use of artichoke extract.
Occupational or airborne exposure to artichoke may also cause allergic reactions. In one case, a 52-year-old male presented with severe spongiotic dermatitis in exposed areas that was recurrent over the past 8 years. A patch test confirmed allergies to artichokes and sesquiterpene lactones, a group of allergens from the Compositae family, and the patient confirmed occupational and airborne exposure to artichokes during the time of his symptoms. The patient improved considerably after treatment with dupilumab (111565).
Gastrointestinal
...Orally, artichoke extract might increase abdominal discomfort, flatulence, diarrhea, hunger, and nausea in some patients (2562,52238,91475).
Abdominal pain and a bitter taste in the mouth were reported by a single person following oral use of a dietary supplement containing artichoke extract, as well as red yeast rice, pine bark extract, and garlic extract (89452). It is not clear if this adverse effect was due to artichoke, other ingredients, or the combination.
In one case report, the autopsy of an 84-year-old female revealed a colonic bezoar comprised of artichoke fiber and fragments. This bezoar caused complete intestinal obstruction, leading to fatal acute peritonitis. Although rare, patients who lack adequate teeth and/or who have a history of gastric surgery are at increased risk for fibrous bezoar formation (97716).
Pulmonary/Respiratory
...Following occupational exposure, allergic symptoms including dyspnea, cough, chest tightness, and asthma symptoms or exacerbation have been reported.
The effects were attributed to sensitization to artichoke. Subsequent nasal challenge with artichoke extract caused reduced nasal patency in these patients (52210,52230).
Orally, severe anaphylactic shock in response to artichoke inulin as an ingredient in commercially available products has been reported (52217). Individuals with a noted sensitivity to artichokes should consume inulin with caution. While rare, individuals with a known inulin allergy should avoid artichoke and artichoke extract.
General
...Orally, boldo is generally well tolerated when used in amounts commonly found in foods.
However, when used in medicinal amounts, boldo can cause significant adverse effects such as hepatotoxicity. There is currently a limited amount of information on the adverse effects of topical boldo; however, a thorough evaluation of safety outcomes has not been conducted.
Most Common Adverse Effects:
Orally: Abdominal pain, nausea, vomiting.
Topically: Dermatitis.
Severe Adverse Effects (Rare):
Orally: Hepatotoxicity, jaundice.
Cardiovascular ...In one report, a 39-year-old obese female developed palpitations and syncope after taking a weight loss supplement containing a combination of boldo, dandelion, and bladderwrack for 3 weeks. The patient was found to have prolonged QT-interval on ECG and frequent episodes of sustained polymorphic ventricular tachycardia (14321). It is not clear whether boldo, another ingredient, or the combination of ingredients is responsible for this adverse effect. The product was not analyzed to determine the presence of any potential toxic contaminants.
Dermatologic ...Topically, boldo can be irritating when applied to the skin (4). In one case report, a healthy 64-year-old patient experienced allergic contact dermatitis in an airborne pattern on the face, arms, and dorsum of both hands following airborne exposure to boldo. After exposure to boldo was avoided, the dermatitis resolved (106433).
Gastrointestinal ...In one case report, a manufacturer of an herbal laxative reformulated their product to contain boldo. Within 5 months of switching to this reformulated product, an 82-year-old male developed abdominal discomfort with gastrointestinal upset including heartburn (13178). In another case, a 72-year-old female reported nausea, vomiting, and anorexia, which were thought to be associated with hepatotoxic effects of a boldo infusion (100304).
Hepatic ...Orally, boldo is thought to potentially cause hepatotoxicity. The volatile oil from the boldo leaf contains the liver toxin, ascaridole. In one case report, a manufacturer of an herbal laxative reformulated their product to contain boldo. Within 5 months of switching to this reformulated product, an 82-year-old male with mild hepatic steatosis and very small gallbladder stones developed elevated liver transaminase levels. Levels normalized following discontinuation of the herbal product (13178). Several other cases of hepatotoxicity have been reported in elderly patients who received infusions of boldo leaves. These patients presented with elevated liver transaminase and bilirubin levels, sometimes up to 200 times the upper limit of normal, as well as nausea, vomiting, anorexia, asthenia, and jaundice. Lab tests and symptoms normalized a few days after stopping boldo (100304,106431).
Immunologic ...Boldo intake has been linked to one case of IgE-mediated anaphylactic allergic reaction (13185).
General ...No adverse effects have been reported. However, a thorough evaluation of safety outcomes has not been conducted.
General
