Studied products include up to 20 mL of a fennel seed oil emulsion; a specific product (ColiMil) containing fennel 164 mg, lemon balm 97 mg, and German chamomile 178 mg; and up to 450 mL of a specific tea (Calma-Bebi, Bonomelli) containing fennel, chamomile, vervain, licorice, and lemon balm (16735,19715,49428).
PREGNANCY: POSSIBLY UNSAFE
when used orally.
Observational research has found that regular use of fennel during pregnancy is associated with shortened gestation (100513).
LACTATION: POSSIBLY UNSAFE
when used orally.
Case reports have linked consumption of an herbal tea containing extracts of fennel, licorice, anise, and goat's rue to neurotoxicity in two breast-feeding infants. The adverse effect was attributed to anethole, a constituent of fennel and anise (16744). However, levels of anethole were not measured in breastmilk, and the herbal tea was not tested for contaminants. Furthermore, other adverse effects related to use of fennel during lactation have not been reported. However, until more is known, avoid using.
LIKELY SAFE ...when the root preparations are used in amounts commonly found in foods. Gentian root is categorized by the FDA as a safe food additive flavoring in the US (4912).
POSSIBLY SAFE ...when gentian root is used orally in a specific combination that contains gentian root, elderflower, verbena, cowslip flower, and sorrel (SinuComp, Sinupret) (374,379,95907). There is insufficient reliable information available about the safety of the topical use of gentian.
PREGNANCY AND LACTATION:
There is insufficient reliable information available about the safety of gentian in medicinal amounts during pregnancy and lactation; avoid using.
LIKELY SAFE ...when used orally and appropriately with lactose-containing foods. Lactase has Generally Recognized as Safe (GRAS) status in the US when prepared from Candida pseudotropicalis or Kluyveromyces lactis (104108,104109). Lactase has been used safely in doses up to 9900 international units (IU) and up to 13,500 food chemical codex (FCC) units (2371,2372,2373,106669).

when used orally and appropriately with lactose-containing foods.
There is insufficient reliable information available about the safety of lipase.
CHILDREN: POSSIBLY UNSAFE
when recombinant human bile salt-stimulated lipase (rhBSSL) is used orally by premature infants.
Adding rhBSSL to infant formula or pasteurized breast milk increases the risk for serious gastrointestinal adverse effects in premature infants (101940).
PREGNANCY AND LACTATION:
Insufficient reliable information available; avoid using.
POSSIBLY SAFE ...when used orally and appropriately. Various proteolytic enzymes have been safely used orally in clinical research (716,964,965,968,969,6252,6253,10622,11457,18281,18284) (91104,91105,91106,91111,96449). Side effects are typically mild to moderate and most often include gastrointestinal effects. See specific monographs for more detailed information related to the safety of individual proteolytic enzymes. ...when used topically and appropriately. Various proteolytic enzymes have been safely used topically in clinical research (67835,67843,67845,91113). Some proteolytic enzymes might cause allergic reactions when used topically. See specific monographs for more detailed information related to the safety of individual proteolytic enzymes.

Insufficient reliable information available; avoid using.
Below is general information about the interactions of the known ingredients contained in the product Digestion with Enzymes. Some ingredients may not be listed. This information does NOT represent a recommendation for or a test of this specific product as a whole.
Theoretically, using topical capsaicin may increase the risk of ACE inhibitor-induced cough.
Details
There is one case report of a topically applied capsaicin cream contributing to the cough reflex in a patient using an ACEI (12414). However, it is unclear if this interaction is clinically significant.
|
Theoretically, capsicum may increase the risk of bleeding if used with anticoagulant or antiplatelet drugs.
Details
In vitro research shows that capsicum might increase the effects of antiplatelet drugs (12406,12407). Also, population research shows that capsicum is associated with an increased risk of self-reported bleeding in patients taking warfarin (12405,20348). However, clinical research shows that taking a single dose of capsaicin (Asian Herbex Ltd.), the active ingredient in capsicum, 400-800 mcg orally in combination with aspirin 500 mg does not decrease platelet aggregation when compared with taking aspirin 500 mg alone. Also, there was no notable effect on measures of platelet aggregation with capsaicin (92990). It is unclear whether capsaicin must be used in more than a single dose to affect platelet aggregation.
|
Theoretically, taking capsicum with antidiabetes drugs might increase the risk of hypoglycemia.
Details
Preliminary clinical research shows that consuming capsicum 5 grams along with a glucose drink attenuates the rise in plasma glucose after 30 minutes by 21%, decreases the 2-hour postprandial area under the curve of plasma glucose by 11%, and increases the 2-hour postprandial area under the curve of plasma insulin by 58% in healthy individuals when compared with placebo (40453,40614). Other clinical research shows that taking capsicum 5 mg daily for 28 days significantly reduces postprandial blood glucose and insulin levels, but not fasting blood glucose and insulin levels, in patients with gestational diabetes (96457).
|
Theoretically, taking capsicum with aspirin might reduce the bioavailability of aspirin.
Details
Animal research shows that acute or chronic intake of capsicum pepper reduces oral aspirin bioavailability (22617). This has not been shown in humans.
|
Theoretically, taking capsicum with ciprofloxacin might increase levels and adverse effects of ciprofloxacin.
Details
Animal research shows that concomitant use of capsaicin, the active constituent of capsicum, and ciprofloxacin increases the bioavailability of ciprofloxacin by up to 70% (22613).
|
Theoretically, taking capsicum with theophylline might increase the levels and adverse effects of theophylline.
Details
|
Theoretically, taking dandelion root along with anticoagulant or antiplatelet drugs might increase the risk of bruising and bleeding.
Details
In vitro research suggests that dandelion root inhibits platelet aggregation (18291).
|
Theoretically, dandelion might increase the risk for hypoglycemia when used with antidiabetes drugs.
Details
Laboratory research suggests that dandelion extract may have moderate alpha-glucosidase inhibitor activity and might also increase insulin secretion (13474,90926). Also, in a case report, a 58-year-old woman with type 2 diabetes who was being treated with insulin developed hypoglycemia 2 weeks after beginning to eat salads containing dandelion (46960).
|
Theoretically, dandelion might increase levels of drugs metabolized by CYP1A2.
Details
Laboratory research suggests that dandelion might inhibit CYP1A2 (12734). So far, this interaction has not been reported in humans. However, until more is known, watch for an increase in the levels of drugs metabolized by CYP1A2 in patients taking dandelion.
|
Theoretically, dandelion might increase the clearance of drugs that are UDP-glucuronosyltransferase substrates.
Details
There is some preliminary evidence that dandelion might induce UDP-glucuronosyltransferase, a phase II enzyme (12734).
|
Theoretically, through diuretic effects, dandelion might reduce excretion and increase levels of lithium.
Details
Animal research suggests that dandelion has diuretic properties (13475). As diuretics can increase serum lithium levels, the dose of lithium might need to be decreased when taken with dandelion.
|
Theoretically, dandelion might increase the risk of hyperkalemia when taken with potassium-sparing diuretics.
Details
Dandelion contains significant amounts of potassium (13465).
|
Theoretically, dandelion might lower fluoroquinolone levels.
Details
Animal research shows that dandelion reduces absorption of ciprofloxacin and can lower levels by 73% (13477). However, this effect has not been reported in humans.
|
Theoretically, fennel might increase the risk of bleeding when used with antiplatelet or anticoagulant drugs.
Details
|
Theoretically, fennel might decrease the levels and clinical effects of ciprofloxacin.
Details
Animal research shows that fennel reduces ciprofloxacin bioavailability by nearly 50%, possibly due to the metal cations such as calcium, iron, and magnesium contained in fennel. This study also found that fennel increased tissue distribution and slowed elimination of ciprofloxacin (6135). |
Theoretically, taking large amounts of fennel might decrease the effects of contraceptive drugs due to competition for estrogen receptors.
Details
|
Theoretically, fennel might increase levels of drugs metabolized by CYP3A4.
Details
|
Theoretically, taking large amounts of fennel might interfere with hormone replacement therapy due to competition for estrogen receptors.
Details
|
Theoretically, taking large amounts of fennel might decrease the antiestrogenic effect of tamoxifen.
Details
Some constituents of fennel have estrogenic activity (11), which may interfere with the antiestrogenic activity of tamoxifen. |
Theoretically, concurrent use might increase risk of hypotension with drugs that lower blood pressure (13439,13441). These include captopril (Capoten), enalapril (Vasotec), losartan (Cozaar), valsartan (Diovan), diltiazem (Cardizem), Amlodipine (Norvasc), hydrochlorothiazide (HydroDiuril), furosemide (Lasix), and many others.

Below is general information about the adverse effects of the known ingredients contained in the product Digestion with Enzymes. 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, beet seems to be well tolerated when used for medicinal purposes, short term.
Most Common Adverse Effects:
Orally: Red stools and red urine.
Serious Adverse Effects (Rare):
Orally: Hypocalcemia and kidney damage when ingested in large amounts.
Endocrine ...Theoretically, ingestion of large quantities of beets could lead to hypocalcemia because of the oxaluric acid content (18).
Gastrointestinal ...Orally, beet juice may cause red stools (94470,97726,100142,100145,105762). This red coloring of the stools is not harmful. Other less common gastrointestinal side effects include loose stools, constipation, and nausea (100149).
Genitourinary ...Orally, beet is known to produce red or pink urine (beeturia) in some people (32569,34134,94464,94470,97725,97726,100142,100145,100152,105762). However, this red coloring of the urine is not harmful.
Neurologic/CNS ...Orally, vivid dreams and worsening headaches have each occurred in one person in a clinical trial, although it is not clear if this is due to beet (97723).
Renal ...Theoretically, ingestion of large quantities of beets could lead to kidney damage due to its oxaluric acid content (18).
General
...Orally, capsicum is generally well tolerated in amounts typically found in food or when the extract is used in doses of up to 200 mg daily.
Topically and intranasally, capsaicin, a constituent of capsicum, is generally well tolerated.
Most Common Adverse Effects:
Orally: Belching, bloating, burning, diarrhea, dyspepsia, gas, headache, mild constipation, nausea, rhinorrhea, skin flushing, and sweating.
Serious Adverse Effects (Rare):
Orally: Cases of myocardial infarction and hypertensive crisis have been reported.
Cardiovascular
...Orally, palpitation was reported in one clinical trial (105196).
One case of myocardial infarction has been reported in a 41-year-old male without cardiovascular risk factors; the event was attributed to the use of an oral capsicum pepper pill that the patient had been taking for weight loss (40768). Another case of coronary vasospasm and acute myocardial infarction has been reported for a healthy 29-year-old male; the event was attributed to the use of a topical capsicum-containing patch that the patient had been applying to the middle of the back for 6 days (40658). Two cases of arterial hypertensive crisis have been reported for individuals who ingested a large amount of peppers and chili peppers the day before. One of the patients also had an acute myocardial infarction, and the other had high levels of thyroid stimulating hormone (40569,40606).
Dermatologic
...Orally, capsicum or its constituent capsaicin may cause urticaria and skin wheals in rare cases (96457,105203).
Topically, capsicum can cause a prickling sensation, itching, pain, burning, edema, stinging, irritation, rash, and erythema. About 1 in 10 patients who use capsaicin topically discontinue treatment because of adverse effects. These effects seem to occur more often with topical formulations containing higher concentrations of capsaicin, the active constituent of capsicum. Side effects tend to diminish with continued use (12401,15260,15261,40358,40439,40483,40547,40676,40682,40719)(40784,40847,92979,92983,92984,96453,105193,105197,105202,111514). In one case, application of a capsaicin 8% patch (Qutenza) for 60 minutes caused a second-degree burn, characterized by burning, erythema, severe pain, and blistering at the administration site. The burn was treated with topical corticosteroids, but 9 months later neuropathic pain persisted, resulting in limited mobility. It is unclear whether the mobility sequalae were caused by topical capsaicin or the patient's pre-existing neurological disorders (111514). Skin contact with fresh capsicum fruit can also cause irritation or contact dermatitis (12408).
Intranasally, capsaicin can cause nasal burning and pain in most patients. It also often causes lacrimation, sneezing, and excessive nasal secretion; however, these side effects appear to diminish with repeat applications (14323,14329,14358). In some cases, the burning sensation disappears after 5-8 applications (14351,14358). In some cases, patients are pretreated with intranasal lidocaine to decrease the pain of intranasal capsaicin treatment. However, even with lidocaine pretreatment, patients seem to experience significant pain (14324).
Gastrointestinal
...Orally, capsicum can cause upper abdominal discomfort, including irritation, fullness, dyspepsia, gas, bloating, nausea, epigastric pain and burning, anal burning, diarrhea, mild constipation, and belching (12403,12410,40338,40427,40456,40503,40560,40584,40605,40665)(40718,40725,40745,40808,40828,96456,96457,105194,105196).
There is a case report of a 3-year-old female who experienced a burning and swollen mouth and lips after touching the arm of a parent that had been treated with a capsaicin patch and then placing the fingers in the mouth (105199). Excessive amounts of capsaicin can lead to gastroenteritis and hepatic necrosis (12404). In a case report, a 40-year-old male with diabetes consumed white wine daily and chewed cayenne which was thought to result in black teeth stains and loss of enamel (40809). Some preliminary research links ingestion of capsaicin with stomach and gallbladder cancer; however the link may be due to contamination of capsaicin products with carcinogens (40771).
Topically, capsaicin can cause diarrhea and vomiting (105202).
Immunologic ...In a case report, a 34-year-old female had anaphylaxis involving difficulty breathing and stupor and also urticaria after consuming a red bell pepper, which is in the capsicum genus. The causal chemical was theorized to be 1,3-beta-glucanase (92978). In another case report, a 33-year-old female experienced angioedema, difficulty breathing and swallowing, and urticaria after ingesting raw green and red peppers (92982).
Neurologic/CNS ...Orally, capsicum can cause sweating and flushing of the head and neck, lacrimation, headache, faintness, and rhinorrhea (7005,12410,105196,105203). Topically, applying capsaicin can cause headache (96450,105202). Injection of capsaicin into the intermetatarsal space has also been associated with headache (96454).
Ocular/Otic
...Topically, capsicum can be extremely irritating to the eyes and mucous membranes.
Capsicum oleoresin, an oily extract in pepper self-defense sprays, causes intense eye pain. It can also cause erythema, blepharospasm, tearing, shortness of breath, and blurred vision. In rare cases, corneal abrasions have occurred (12408,12409,40345,40348,40383,40720,40857).
Inhalation of capsicum can cause eye irritation, and allergic alveolitis (5885). In a case report, a 38-year-old female had acute anterior uveitis that developed about 12 hours after using a specific patch (Isola Capsicum N Plus) that contained capsaicin 1.5 mg per patch and methyl salicylate 132 mg per patch for neck pain. The uveitis was controlled with topical steroids and did not recur (92977).
Oncologic ...Population research suggests that moderate to high intake of capsaicin, the active constituent of capsicum, is associated with an increased risk of gastric cancer, while low intake is associated with a decreased risk. It is not clear from the study what amount of capsaicin is considered high versus low intake (92988). Additionally, some research suggests that any link may be due to contamination of capsaicin products with carcinogens (40771).
Pulmonary/Respiratory
...Orally, difficulty breathing was reported in a clinical trial (105196).
Topically, nasopharyngitis related to the use of a cream containing capsaicin has been reported (105202).
Inhalation of capsicum and exposure to capsicum oleoresin spray can cause cough, dyspnea, pain in the nasal passages, sneezing, rhinitis, and nasal congestion (5885,15016,40522,40546,40647). In rare cases, inhalation of the capsicum oleoresin or pepper spray has caused cyanosis, apnea, respiratory arrest and death in people. Death was caused by asphyxiation probably due to acute laryngeal edema and bronchoconstriction from inhalation of the capsicum oleoresin spray (40546,40672,40837,40879).
In a case report, a 47-year-old female who was exposed to capsaicin gas for more than 20 minutes experienced acute cough, shortness of breath, short-term chest pain, wheezing, and difficulty breathing for months afterwards (92980). In rare cases, exposure to capsicum oleoresin spray resulted in apnea, pulmonary injury, cyanosis, and even respiratory arrest (40383,40546).
General
...Orally, dandelion seems to be well tolerated.
Most Common Adverse Effects:
Orally: Diarrhea, heartburn, and stomach discomfort.
Topically: Dermatitis in sensitive individuals.
Serious Adverse Effects (Rare):
Orally: Anaphylaxis in sensitive individuals.
Cardiovascular ...In one report, a 39-year-old obese woman developed palpitations and syncope after taking a weight loss supplement containing a combination of dandelion, bladderwrack, and boldo 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 dandelion, 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, dandelion can cause contact dermatitis and erythema multiforme in sensitive individuals. Dandelion can cause an allergic reaction in individuals sensitive to the Asteraceae/Compositae family (13478,13481,42893,46945,46977). Members of this family include ragweed, chrysanthemums, marigolds, daisies, and many other herbs.
Endocrine ...In one report, a 56-year-old man with renal impairment developed hyperoxalaemia and peripheral gangrene after ingesting large amounts of dandelion tea (10 to 15 cups daily for 6 months). The adverse effect was attributed to the high oxalate content of dandelion tea (258 mcmol/L) and reduced renal oxalate clearance caused by renal impairment (90639). In another report, a 58-year-old woman with type 2 diabetes who was being treated with insulin developed hypoglycemic symptoms 2 weeks after beginning to eat salads containing dandelion (46960). The hypoglycemic effect was attributed to the potential alpha-glucosidase inhibitory activity of dandelion.
Gastrointestinal ...Gastrointestinal symptoms, including stomach discomfort, diarrhea, and heartburn, have been reported following oral use of dandelion (19146,36931). A case of intestinal blockage has been reported for a patient who ingested a large amount of dandelion greens three weeks after undergoing a stomach operation (46981). Also, a case of hemorrhagic cystitis has been reported for a 33-year-old woman who took a specific herbal product (Slim-Kombu, Balestra and Mech, Vicenza, Italy) containing 20 herbal extracts, including dandelion extract. Symptoms resolved after the patient discontinued using the product, and symptoms resumed when the patient began taking the supplement again four months later. While various ingredients in the supplement may have contributed to the symptoms, it is possible that dandelion extract may have contributed to the effect due to its diurectic, laxative, cholagogue, and antirheumatic properties (46959).
Other ...Orally, products containing dandelion pollen can cause allergic reactions, including anaphylaxis (13479,13480). Also, rhinoconjunctivitis and asthma have been reported after handling products such as bird feed containing dandelion and other herbs, with reported positive skin tests for dandelion hypersensitivity (46948). Dandelion pollen may cause pollinosis, such as allergic rhinitis and conjunctivitis (18065,46951,46964,46966,46972).
General
...Orally and topically, fennel seems to be well tolerated.
Most Common Adverse Effects:
Orally: Gastrointestinal discomfort, photosensitivity, and allergic reactions in sensitive individuals.
Serious Adverse Effects (Rare):
Orally: Seizures.
Dermatologic ...Advise patients to avoid excessive sunlight or ultraviolet light exposure while using fennel (19). Allergic reactions affecting the skin such as atopic dermatitis and photosensitivity may occur in patients who consume fennel (6178,49507).
Gastrointestinal ...Orally, fennel may cause gastrointestinal complaints, including nausea and vomiting (19146,104196).
Hematologic ...Methemoglobinemia has been reported in four infants following intoxication related to ingestion of a homemade fennel puree that may have been made from improperly stored fennel (49444).
Immunologic ...A case report describes an 11-year-old male who developed an allergy to fennel-containing toothpaste. Immediately after using the toothpaste, the patient experienced sneezing, coughing, itchy mouth, rhinorrhea, nasal congestion, wheezing, difficulty breathing, and palpitations, which resolved within 10 minutes of spitting out the toothpaste and rinsing the mouth. In challenge tests, the patient reacted to chewing fresh fennel root, but not ground fennel seeds (103822).
Neurologic/CNS ...Orally, fennel oil has been associated with tonic clonic and generalized seizures (12868). New-onset cluster headaches are reported in a 24-year-old female while using a toothpaste containing fennel and camphor for 3 months. The headaches resolved upon stopping the toothpaste (112368). It is unclear if this adverse effect can be attributed to fennel, camphor, or the combination.
Pulmonary/Respiratory ...Orally, fennel and fennel seed have been reported to cause bronchial asthma (49478).
General ...Orally, gentian root, in combination with other herbs, seems to be generally well tolerated (95907). Side effects reported in clinical studies include gastrointestinal discomfort and allergic skin reactions (374,379). There is insufficient reliable information available about the adverse effects of gentian when taken as a medicine alone.
Gastrointestinal ...Orally, gentian root, in combination with other herbs, has been reported to cause gastrointestinal adverse effects (374,379). Gastrointestinal intolerance occurred in patients with cancer-associated anorexia who took gentian tincture 1 mL three times daily, in conjunction with turmeric 1 gram and ginger 1 gram twice daily, for 14 days. Six of 17 patients discontinued the regimen due to nausea, 3 due to vomiting, 2 due to diarrhea, and 2 due to bloating. It is unclear if this gastrointestinal intolerance was caused by gentian, the other herbs, or the patients' predisposing conditions (96263).
Immunologic ...Orally, gentian root, in combination with other herbs, has been reported to cause allergic skin reactions (374,379). It is unclear if these reactions were caused by gentian, the other herbs, or the combination.
General ...Orally, lactase is generally well tolerated.
Immunologic ...A case of lactase-induced contact dermatitis and immunoglobulin E (IgE)-mediated allergic rhinoconjunctivitis has been reported in a worker exposed to powdered lactase. Allergy to lactase was confirmed by prick test, open application test, and chamber challenge test (96348).
General
...No adverse effects have been reported in adults.
However, a thorough evaluation of safety outcomes has not been conducted.
Serious Adverse Effects (Rare):
Orally: Gastrointestinal adverse effects, such as necrotizing enterocolitis, when recombinant human bile salt-stimulated lipase is used in premature infants.
Gastrointestinal ...Orally, when added to the formula or pasteurized breast milk consumed by premature infants, recombinant human bile salt-stimulated lipase (rhBSSL) can cause gastrointestinal adverse effects, including abdominal distension, flatulence, constipation, colic, abdominal pain, gastroenteritis, vomiting, regurgitation, and rectal bleeding (101940). Premature infants receiving rhBSSL also had a slightly higher rate of necrotizing enterocolitis (NEC) when compared with those receiving placebo. After review by a panel of experts, it was determined that the rate of confirmed or suspected NEC in infants consuming rhBSSL was 3.3%, compared with 0.5% in those receiving placebo. Although this rate of NEC is lower than the historical rate of occurrence in premature infants (11%), a possible increased risk for NEC cannot be ruled out (101940).
General
...Orally, proteolytic enzymes are generally well tolerated.
See specific monographs for detailed safety information related to individual proteolytic enzymes.
Most Common Adverse Effects:
Orally: Gastrointestinal upset.
Serious Adverse Effects (Rare):
Topically: Allergic reactions.
Gastrointestinal ...Orally, some patients taking proteolytic enzymes may have gastrointestinal complaints (101517).
Immunologic ...Proteolytic enzymes are commonly found in laundry detergents and pre-spotter products. Rarely, protease specific IgE positive tests possibly related to these products have occurred. Exposure may be airborne or topical (102705). In addition, in case reports, occupational exposure to the airborne proteolytic enzyme pepsin has resulted in allergic rhinoconjunctivitis or asthma (102706,102707).
