Below is general information about the safety of the known ingredients contained in the product Kids Immune Fortifier Alcohol Free. 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. Doses of astragalus up to 60 grams daily for up to 4 months have been used without reported adverse effects (32920,33038,95909). ...when used intravenously. Infusion of doses up to 80 grams daily for up to 4 months under the supervision of a medical professional have been used with apparent safety (32811,32812,32828,95909). There is insufficient reliable information available about the safety of astragalus when used topically.
PREGNANCY AND LACTATION:
There is insufficient reliable information in humans.
However, astragaloside, a constituent of astragalus, has maternal and fetal toxic effects in animals (32881). Avoid using.
LIKELY SAFE ...when consumed in amounts commonly found in foods. Cassia cinnamon has Generally Recognized As Safe (GRAS) status in the US for use as a spice or flavoring agent (4912) ...when used orally and appropriately, short-term. Cassia cinnamon 1-2 grams daily has been used safely for up to 3 months (17011,21914). Cassia cinnamon 3-6 grams daily has been used safely for up to 6 weeks (11347,14344). Cassia cinnamon extract corresponding to 3 grams daily of cassia cinnamon powder has also been used safely for up to 4 months (21916).
POSSIBLY SAFE ...when used topically, short-term. Cassia cinnamon oil 5% cream applied topically to the legs has been used safely in one clinical trial (59580).
POSSIBLY UNSAFE ...when used orally in high doses, long-term. Some cassia cinnamon products contain high levels of coumarin. Coumarin can cause hepatotoxicity in animal models (15299,21920). In humans, very high doses of coumarin from 50-7000 mg daily can result in hepatotoxicity that resolves when coumarin use is discontinued (15302). In most cases, ingestion of cassia cinnamon will not provide a high enough amount of coumarin to cause significant toxicity; however, in especially sensitive people, such as those with liver disease, prolonged ingestion of large amounts of cassia cinnamon might exacerbate the condition.
CHILDREN: POSSIBLY SAFE
when used orally and appropriately, short-term.
Cassia cinnamon 1 gram daily has been used safely in adolescents 13-18 years of age for up to 3 months (89648).
PREGNANCY AND LACTATION: LIKELY SAFE
when consumed in amounts commonly found in foods (4912).
There is insufficient reliable information available about the safety of cassia cinnamon when used in medicinal amounts during pregnancy and breast-feeding. Stay on the safe side and stick to food amounts.
LIKELY SAFE ...when consumed in amounts commonly found in foods. Ceylon cinnamon has Generally Recognized As Safe (GRAS) status in the US for use as a spice or flavoring agent (4912).
POSSIBLY SAFE ...when used orally and appropriately in medicinal amounts. Ceylon cinnamon 0.5-3 grams daily has been safely used in studies lasting up to 6 months (4,12,97248,97250,99874). ...when used as a mouth rinse for up to 15 days (92071). There is insufficient reliable information available about the safety of Ceylon cinnamon when used orally in greater amounts or for longer periods. Ceylon cinnamon contains trace amounts of coumarin (108260). In very high doses, coumarin can cause hepatotoxicity (15302). However, since the amount of coumarin in Ceylon cinnamon is negligible, it is unlikely to cause toxic effects (89652,92072,92073).
PREGNANCY: LIKELY SAFE
when consumed in amounts commonly found in foods (4912).
PREGNANCY: LIKELY UNSAFE
when used orally in amounts greater than those found in foods.
Fetal abnormalities have been reported in animals (4,12).
LACTATION: LIKELY SAFE
when consumed in amounts commonly found in foods (4912).
There is insufficient reliable information available about the safety of Ceylon cinnamon in amounts greater than those found in foods.
LIKELY SAFE ...when used orally and appropriately, short-term. Various liquid extracts of Echinacea purpurea have been used safely for up to 10 days, including EchinaGuard (Madaus AG) 20 drops every 2 hours for 1 day, then three times daily (10320), or Echinilin (Inovobiologic Inc.) 40 mL in divided doses for 1 day, then 15 mL in divided doses daily thereafter (12355,20062). Other liquid extracts have been used safely for relatively longer periods, including Echinaforce (A. Vogel Bioforce AG) 2.4 grams daily for 4 months or 1.6 grams daily for 6 months (7087,18225), and Echinacin (Madaus AG) 5 mL twice daily for 10 days, or 4 mL twice daily for 8 weeks (3282,10802). Specific solid dosage forms of echinacea that have been used safely for up to 10 days include Echinacea purpurea above-ground parts (EchinaFresh, Enzymatic Therapy) 300 mg daily (11970), and mixtures of Echinacea purpurea and Echinacea angustifolia herb in divided doses of 6 grams to 10.5 grams for 1 day then 3 grams to 5.1 grams daily (10800,17519,20059). A specific Echinacea angustifolia extract (ExtractumPharma ZRT) has also been used with apparent safety at a dose of 40 mg once or twice daily for up to 7 days (20064,103233). An Echinacea purpurea product (Natures Resource) has been used safely at a dose of 1.8 grams daily for 8 weeks (17521), and echinacea (Puritan's Pride) has been used safely at 8 grams daily for 28 days (20066).
POSSIBLY SAFE ...when used topically, short-term. A specific cream (Linola Plus Cream, Dr. August Wolff GmbH & Co.) containing echinacea extract (WO 3260) has been applied to the skin safely 2-3 times daily for up to 12 weeks (97499). There is insufficient reliable evidence about the safety of echinacea when used parenterally.
CHILDREN: POSSIBLY SAFE
when used orally, short-term.
Some clinical research shows that an extract of the above-ground parts of Echinacea purpurea (EC31J2, Echinacin Saft, Madaus AG) in a dose of 3.75 mL twice daily (for ages 2 years to 5 years) or 7.5 mL twice daily (for ages 6 years to 11 years) is safe when used for up to 10 days (4989). However, about 7% of children experienced a rash after taking echinacea, which might have been caused by an allergic reaction (4989). There is concern that allergic reactions could be severe in some children. The Medicines and Healthcare Products Regulatory Agency in the United Kingdom recommends against the use of oral echinacea products in children under 12 years of age due to this risk of allergic reaction (18207). In contrast, another clinical study in children 4-12 years old shows that a specific Echinacea purpurea product (Echinaforce Junior, A. Vogel) does not cause allergic or urticarial reactions more frequently than vitamin C (105719).
PREGNANCY: POSSIBLY SAFE
when used orally, short-term.
There is preliminary evidence that mothers can safely use echinacea in the form of E. purpurea or E. angustifolia solid dosage forms, 250-1000 mg daily, or tinctures, up to 30 drops daily, for 5 days to 7 days during the first trimester without adversely affecting the fetus (7056,13418,15123). There is insufficient reliable information available about the safety of echinacea when used for longer than 7 days.
LACTATION:
Insufficient reliable information available; avoid using.
LIKELY SAFE ...when used orally in the amounts typically found in foods. Elderberry has generally recognized as safe (GRAS) status in the US (4912).
POSSIBLY SAFE ...when elderberry fruit extract is used orally, short-term. One specific elderberry fruit extract (Sambucol, Nature's Way) has been used with apparent safety for up to 5 days (5260,12235,103831); another (BerryPharma, Iprona AG) has been used with apparent safety for up to 15 days (91374). A specific elderberry fruit extract lozenge (ViraBLOC, HerbalScience) has been used with apparent safety for 2 days (17022). Other elderberry fruit extracts have been used with apparent safety for up to 12 weeks (21141,21142).
POSSIBLY UNSAFE ...when elder tree leaves and stems, or unripe or uncooked elderberries, are consumed. The unripe green fruit, as well as the leaves and stems of the elder tree, contain a cyanide-producing chemical, which can cause serious toxicity (17020,17021,21143,21144,91374). Cooking eliminates the toxin.
CHILDREN: LIKELY SAFE
when consumed in the amounts typically found in foods.
CHILDREN: POSSIBLY SAFE
when used orally for up to 3 days.
A specific fruit extract (Sambucol, Nature's Way) has been used in doses of 15 mL twice daily for 3 days in children 5 years and older (5260,103831).
CHILDREN: POSSIBLY UNSAFE
when unripe or uncooked elderberries are consumed.
The unripe green fruit, as well as the leaves and stems of the elder tree, contain a cyanide-producing chemical , which can cause serious toxicity (17020,17021,21143,21144,91374). Cooking eliminates the toxin.
PREGNANCY AND LACTATION: LIKELY SAFE
when consumed in the amounts typically found in foods.
There is insufficient reliable information available about the safety of elderberry when used for medicinal purposes; avoid using in amounts greater than those found in foods.
POSSIBLY SAFE ...when an extract of reishi mushroom is used orally and appropriately for up to one year (12,5485,70767,70774,70786,70799,70800,70801,70802). ...when whole powdered reishi mushroom is used orally and appropriately for up to 16 weeks (70776,70799,70800,70801,91433,91435,91436,91437,108309).

Below is general information about the interactions of the known ingredients contained in the product Kids Immune Fortifier Alcohol Free. 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, taking astragalus with antidiabetes drugs might increase the risk of hypoglycemia.
 Details
|
Theoretically, astragalus might interfere with cyclophosphamide therapy.
Details
|
Theoretically, astragalus might interfere with immunosuppressive therapy.
Details
|
Theoretically, astragalus might increase levels and adverse effects of lithium.
Details
Animal research suggests that astragalus has diuretic properties (15103). Theoretically, due to this diuretic effect, astragalus might reduce excretion and increase levels of lithium.
|
Theoretically, cassia cinnamon may have additive effects with antidiabetes drugs.
Details
|
Theoretically, large doses of cassia cinnamon might cause additive effects when used with hepatotoxic drugs.
Details
There is some concern that ingesting large amounts of cassia cinnamon for an extended duration might cause hepatotoxicity in some people. Cassia cinnamon contains coumarin, which can cause hepatotoxicity in animal models (15299,21920). In humans, very high doses of coumarin from 50-7000 mg/day can result in hepatotoxicity that resolves when coumarin use is discontinued (15302,97249). Lower amounts might also cause liver problems in sensitive people, such as those with liver disease or those taking potentially hepatotoxic agents.

Theoretically, Ceylon cinnamon might have additive effects with antihypertensive drugs and increase the risk of hypotension.
Details

Echinacea can increase plasma levels of caffeine by inhibiting its metabolism.
Details
Echinacea seems to increase plasma concentrations of caffeine by around 30% (12155). This is likely due to inhibition of cytochrome P450 1A2 (CYP1A2) by echinacea.
|
Echinacea might inhibit the metabolism of CYP1A2 and increase plasma levels of some drugs.
Details
Echinacea appears to inhibit CYP1A2 enzymes in humans. Additionally, echinacea seems to increase plasma concentrations of caffeine, a CYP1A2 substrate, by around 30% (12155). Theoretically, echinacea might increase levels of other drugs metabolized by CYP1A2.
|
Echinacea may induce hepatic CYP3A4 and inhibit intestinal CYP3A4. This may increase or decrease levels of drugs metabolized by CYP3A4.
Details
Several clinical trials have shown that taking echinacea for up to one month does not significantly affect the metabolism of various CYP3A4 substrates, including midazolam, docetaxel, etravirine, lopinavir-ritonavir, and darunavir-ritonavir (13712,48618,88164,88165). However, other clinical research shows that echinacea may increase the clearance of midazolam, suggesting that echinacea might induce CYP3A4 (48618). The discrepancy is thought to be due to differing effects of echinacea on intestinal versus hepatic CYP3A4 enzymes. Echinacea appears to induce hepatic CYP3A4 but inhibit intestinal CYP3A4 (12155). In some cases, these effects might cancel each other out, but in others, drug levels may be increased or decreased depending on the level of effect at hepatic and intestinal sites. The effect of echinacea on CYP3A4 activity may differ depending on the CYP3A4 substrate (6450,11026,88162,88167).
|
Theoretically, echinacea may interfere with the metabolism of darunavir; however, a small clinical study found no effect.
Details
Darunavir is metabolized by cytochrome P450 3A4 (CYP3A4) and is administered with the CYP3A4 inhibitor ritonavir to increase its plasma concentrations. Echinacea has variable effects on CYP3A4, but administration of an E. purpurea root extract (Arkocapsulas Echinacea, Arkopharma) 500 mg four times daily for 14 days did not affect darunavir/ritonavir pharmacokinetics in 15 HIV-infected patients (88163,93578).
|
Theoretically, echinacea may interfere with the metabolism of docetaxel; however, a small clinical study found no effect.
Details
Docetaxel is metabolized by cytochrome P450 3A4 (CYP3A4). Echinacea has variable effects on CYP3A4, but taking E. purpurea whole plant extract (Echinaforce, A. Vogel Biopharma AG) 20 drops three times daily for 2 weeks did not alter the pharmacokinetics of docetaxel in one clinical study (88164).
|
Echinacea may increase levels of etoposide.
Details
In one report, concomitant use of etoposide and echinacea was associated with more severe thrombocytopenia than the use of etoposide alone, suggesting inhibition of etoposide metabolism (20082). Etoposide is a cytochrome P450 3A4 (CYP3A4) substrate. Echinacea has variable effects on CYP3A4, but some studies have reported inhibition of the enzyme (6450,11026,12155,88162,88167).
|
Theoretically, echinacea may interfere with the metabolism of etravirine; however, a small clinical study found no effect.
Details
|
Echinacea has immunostimulant activity which may interfere with immunosuppressant therapy.
Details
|
Theoretically, echinacea may interfere with the metabolism of lopinavir; however, a small clinical study found no effect.
Details
Lopinavir is metabolized by cytochrome P450 3A4 (CYP3A4) and is administered with the CYP3A4 inhibitor ritonavir to increase its plasma concentrations. Echinacea has variable effects on CYP3A4, but taking E. purpurea (Echinamide, Natural Factors Nutritional Products, Inc.) 500 mg three times daily for 14 days did not alter the pharmacokinetics of lopinavir/ritonavir in healthy volunteers (48618,93578).
|
Theoretically, echinacea may increase the metabolism of intravenous midazolam.
Details
Echinacea induces hepatic CYP3A4 and might decrease plasma levels of midazolam by about 20%, reducing the effectiveness of intravenous midazolam (12155). Echinacea also appears to inhibit intestinal CYP3A4, which could theoretically increase the bioavailability of oral midazolam. This may cancel out the decrease in availability caused by induction of hepatic CYP3A4, such that overall plasma levels after oral administration of midazolam are not affected by echinacea.
|
Echinacea seems to increase the clearance of warfarin, although the effect may not be clinically significant.
Details
Preliminary clinical research in healthy male volunteers suggests that taking echinacea increases the clearance of the active S-isomer of warfarin after a single dose of warfarin, but there was not a clinically significant effect on the INR (20083).
|
Theoretically, elderberry might interfere with immunosuppressant therapy due to its immunostimulant activity.
Details
Elderberry has immunostimulant activity, increasing the production of cytokines, including interleukin and tumor necrosis factor (10796).
|
Theoretically, high doses of reishi mushroom might increase the risk of bleeding.
Details
|
Theoretically, reishi mushroom might have additive effects with antidiabetes drugs.
Details
|
Theoretically, concurrent use of reishi mushroom with antihypertensive drugs might increase the risk of hypotension.

Below is general information about the adverse effects of the known ingredients contained in the product Kids Immune Fortifier Alcohol Free. 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 and intravenously, astragalus root seems to be well tolerated.
Topically, no adverse effects have been reported. However, a thorough evaluation of safety outcomes has not been conducted.
Serious Adverse Effects (Rare):
Orally: A case report raises concerns about liver and kidney cysts with astragalus use.
Cardiovascular ...Orally, astragalus has reportedly been associated with lacunar angina in one clinical trial. However, this may not have been caused by astragalus (17355). In addition, rapid intravenous administration of astragalus has resulted in temporary palpitations (32812).
Dermatologic ...Intravenously, astragalus may cause rash, eczema, and pruritus (33034).
Gastrointestinal ...Orally, astragalus has reportedly been associated with enterocolitis and nausea in one clinical trial. However, these effects may not have been caused by astragalus (17355).
Genitourinary ...Orally, astragalus has reportedly been associated with vulvitis in one clinical trial. However, this effect may not have been caused by astragalus (17355).
Hepatic ...A case of high serum CA19-9 levels and small liver and kidney cysts has been reported for a 38-year-old woman who drank astragalus tea daily for one month. Levels returned to normal after one month, and cysts disappeared after ten months. Both symptoms returned following a resumption of astragalus use. The authors state that astragalus was the likely cause given the temporal relationship (90658).
Neurologic/CNS ...Rapid intravenous administration of astragalus has resulted in temporary dizziness (32812).
Pulmonary/Respiratory ...Orally, astragalus has reportedly been associated with rhinosinusitis and pharyngitis in one clinical trial. However, these effects may not have been caused by astragalus (17355).
Renal ...A case of high serum CA19-9 levels and small liver and kidney cysts has been reported for a 38-year-old woman who drank astragalus tea daily for one month. Levels returned to normal after one month, and cysts disappeared after ten months. Both symptoms returned following a resumption of astragalus use. The authors state that astragalus was the likely cause given the temporal relationship (90658).
General
...Orally, cassia cinnamon appears to be well-tolerated.
Significant side effects have not been reported in most patients.
Most Common Adverse Effects:
Topically: Burning mouth, stomatitis.
Dermatologic
...In one clinical trial, a rash was reported in one patient taking cassia cinnamon 1 gram daily for 90 days (17011).
In one case, a 58-year-old female with a documented allergy to topically applied cinnamic alcohol presented with eyelid dermatitis, which was found to be a manifestation of systemic contact dermatitis to cinnamon in the diet. Symptoms improved in two days and completely cleared five days after discontinuing the addition of cinnamon to food products (95599). In other case reports, two adults presented with allergic contact cheilitis following the ingestion of chai tea with cinnamon and yogurt with cinnamon. Cinnamon components were confirmed as the causative allergic agents with patch tests, and both cases of allergic contact cheilitis completely resolved upon cessation of the cinnamon-containing products (113516,113515).
Topically, allergic skin reactions and stomatitis from toothpaste flavored with cassia cinnamon have been reported (11915,11920). Intraoral allergic reactions with symptoms of tenderness and burning sensations of the oral mucosa have also been reported in patients using breath fresheners, toothpaste, mouthwash, candy, or chewing gum containing cinnamon, cinnamic aldehyde or cinnamic alcohol as flavoring agents. Glossodynia, or burning mouth syndrome, has also been reported in a 62-year-old female who ate apples dipped in cinnamon nightly (95598), and allergic contact dermatitis has been reported in a teenage female using a homemade cinnamon sugar face scrub (95596).
Endocrine ...In one clinical trial, a hypoglycemic seizure was reported in one patient taking cassia cinnamon 1 gram daily for 3 months. The event occurred one day after enrolling in the study (89648). It is unclear if cassia cinnamon caused this event.
Hepatic ...There is some concern about the safety of ingesting large amounts of cassia cinnamon for extended durations due to its coumarin content. Coumarin can cause hepatotoxicity in animal models (15299). In humans, very high doses of coumarin from 50-7000 mg/day can result in hepatotoxicity that resolves when coumarin is discontinued (15302). In clinical trials, taking cassia cinnamon 360 mg to 12 grams daily for 3 months did not significantly increase levels of aspartate transaminase (AST) or alanine transaminase (ALT) (21918,96280,108259). However, in one case report, acute hepatitis with elevated AST and ALT occurred in a 73-year-old female who started taking a cinnamon supplement (dose unknown) one week prior to admission. The cinnamon supplement was added on to high-dose rosuvastatin, which may have led to additive adverse hepatic effects. After discontinuing both products, liver function returned to normal, and the patient was able to restart rosuvastati without further complications (97249). In most cases, ingestion of cassia cinnamon won't provide a high enough amount of coumarin to cause significant toxicity; however, in especially sensitive people, such as those with liver disease or taking potentially hepatotoxic agents, prolonged ingestion of large amounts of cassia cinnamon might exacerbate the condition.
Immunologic ...An unspecified allergic reaction was reported in one patient taking cassia cinnamon 1 gram daily for 3 months (89648).
General
...Orally, Ceylon cinnamon is generally well tolerated, and adverse reactions are uncommon.
Most Common Adverse Effects:
Orally: Bloating, dyspepsia, nausea.
Topically: Allergic dermatitis, irritation of mucous membranes and skin.
Dermatologic
...Orally, a case of systemic contact dermatitis has been reported in a patient who consumed cinnamon (type not specified) after being previously sensitized to cinnamyl alcohol via cutaneous exposure (95599).
In a small study of oral Ceylon cinnamon, two patients reported itching (104520). In another small study, two patients reported rashes (108263).
Topically, cinnamon oil can cause skin irritation and allergic dermatitis, probably due to cinnamaldehyde which makes up 60% to 80% of cinnamon oil (2537,12635,92071,95596,95599). In one case report, a 16-year-old female experienced worsening dermatitis after using a homemade facial scrub containing cinnamon powder (type not specified). Symptoms improved after discontinuation of the scrub (95596). Several cases of intraoral allergic contact dermatitis have been reported in patients consuming cinnamon (type not specified) or using products containing constituents of cinnamon (95598).
Gastrointestinal ...Orally, gastrointestinal side effects such as heartburn, nausea, bloating, and dyspepsia have been reported (97250).
Hematologic ...Orally, a case of postoperative hemorrhage is reported in a 49-year-old patient after taking Ceylon cinnamon 1 tablespoon daily for 10 months. One day post-colectomy, the patient had an INR of 1.59 and intraabdominal bleeding that required exploratory laparotomies, blood transfusion, and fresh frozen plasma. Ultimately, the patient was discharged (112421).
Hepatic ...While there is concern about the coumarin content in cassia cinnamon increasing the risk for hepatic adverse effects and bleeding, the amount of coumarin in Ceylon cinnamon is negligible and unlikely to cause toxic effects (89652,92072,92073). In one case report, a 73-year-old female taking rosuvastatin for several months developed elevated liver function tests (LFTs), abdominal pain, nausea, and vomiting after taking cinnamon (unknown dose and type) for 7 days. The acute hepatitis and elevated LFTs resolved after stopping both cinnamon and rosuvastatin. The patient was later able to resume rosuvastatin without recurrence (97249).
General
...Orally, echinacea is well tolerated.
Most Common Adverse Effects:
Orally: Abdominal pain, constipation, diarrhea, heartburn, nausea and vomiting, rashes, and stomach upset.
Serious Adverse Effects (Rare):
Orally: Severe allergic reactions and hepatitis have been reported.
Dermatologic ...Itching, urticaria, tingling, and allergic rashes have been reported with various echinacea preparations (8225,12355,17519,20059,20077,101592,111530,111540). In a study of children aged 2-11 years, rash occurred in about 7% of children treated with an extract of the above-ground parts of E. purpurea (EC31J2, Echinacin Saft, Madaus AG), compared with about 3% of those treated with placebo (4989,95652). There is concern that allergic reactions could be severe in some children. The Medicines and Healthcare Products Regulatory Agency in the United Kingdom (UK) recommends against the use of oral echinacea products in children under 12 years of age due to this risk of allergic reaction (18207). However, another study in children 4-12 years old shows that a specific E. purpurea product (Echinaforce Junior, A. Vogel) did not cause allergic or urticarial reactions more frequently than vitamin C (105719).
Gastrointestinal ...Gastrointestinal adverse effects include nausea and vomiting, abdominal pain, stomach upset, heartburn, diarrhea, and constipation (10802,11970,12355,13419,17519,20059,48680,105719,106626). An unpleasant taste, dry mouth, and burning, tingling or numbness of the tongue also occur (11970,12355,17519,20059,20070,20077).
Hematologic ...A 51-year-old female presented with leukopenia after taking echinacea 450 mg three times daily for 2 months, along with ginkgo biloba, multivitamins, and calcium. Her leukocyte count recovered upon stopping these supplements, but dropped again when she restarted echinacea alone about a year later. The problem resolved when echinacea was stopped permanently (48533). A 32-year-old male presented with severe thrombotic thrombocytopenic purpura (TTP) about 2 weeks after using an extract of E. pallida to treat a cold. He required admission to an intensive care unit and extensive plasmapheresis. The authors speculate that immunostimulant effects of echinacea induced or exacerbated the TTP (48572).
Hepatic
...Although uncommon, cases of echinacea-induced hepatitis have been reported.
One case report describes acute cholestatic autoimmune hepatitis in a 45-year-old male who had been taking an echinacea root extract 1500 mg daily for about 2 weeks. He presented with significantly elevated liver function tests (LFTs), elevated immunoglobulin G (IgG) levels, and a positive test for anti-smooth muscle antibodies, indicating an autoimmune process. Elevated LFTs and IgG levels returned to normal within one month of stopping echinacea (17518). Another case report describes acute cholestatic hepatitis in a 44-year-old male who had taken echinacea root tablets 600 mg daily for 5 days to treat flu-like symptoms. He presented with elevated LFTs, prothrombin time, and international normalized ratio (INR). His condition gradually improved after stopping echinacea, and his LFTs normalized within 3 months (91528).
Seven cases of hepatitis associated with echinacea use were reported to the Australian Adverse Drug Reactions Advisory Committee between 1979 and 2000, but specific details are lacking (8225).
One case report describes acute liver failure in a 2 year-old child who had been given about 100 mg of echinacea daily for 2 weeks. The patient presented with jaundice, diarrhea, lethargy, anorexia, and significantly elevated LFTs. A liver biopsy showed hepatocyte swelling, spotty necrosis, and inflammatory infiltrate with eosinophils. A full recovery was made over a 2-week period (88166).
Immunologic
...Allergic reactions, including urticaria, runny nose, dyspnea, bronchospasm, acute asthma, angioedema, and anaphylaxis, have been reported with various echinacea preparations (638,1358,8225).
Atopic individuals and those sensitive to other members of the Asteraceae family (ragweed, chrysanthemums, marigolds, daisies) seem to be at higher risk for these reactions (1358,8225).
A case report describes a 36-year-old female who presented with muscle weakness, electrolyte abnormalities, renal tubular acidosis, fatigue, and dry mouth and eyes after taking echinacea, kava, and St. John's Wort for 2 weeks., She also had a positive antinuclear antibody (ANA) test, with elevated anti-dsDNA antibodies SSA and SSB. Sjogren syndrome was diagnosed; the authors hypothesize that it may have been triggered by the immunostimulant effects of echinacea (10319). A 55-year-old male with a history of pemphigus vulgaris in remission for about a year experienced a flare of the disease after taking an echinacea supplement for one week. After stopping echinacea, medical treatment resulted in partial control of the disease (12171). Another case report describes a 58-year-old male who presented with marked eosinophilia and elevated immunoglobulin E (IgE) levels while taking an echinacea supplement. He required prednisone therapy until he stopped taking echinacea 3 years later, at which time his eosinophils and IgE normalized (48623). A 41-year-old male experienced four episodes of erythema nodosum, each occurring after he had taken echinacea for early symptoms of influenza. After stopping echinacea, he had no further exacerbations of erythema nodosum, suggesting that it had been triggered by the immunostimulant effects of echinacea (7057).
Musculoskeletal ...Reports of arthralgia and myalgia have been associated with echinacea (13418).
Neurologic/CNS ...Headache has been reported in people taking various echinacea preparations orally (3282,11970,17519,20059,20064). Dizziness has also been reported (3282,8225,11970). In one study using an alcoholic extract of the above-ground parts of E. purpurea (EC31J0, Echinacin, Madaus AG), somnolence and a tendency to aggressiveness were reported (3282).
General
...Orally, elderberry extracts prepared from ripe fruit seem to be well tolerated.
Most Common Adverse Effects:
Orally: When adverse effects occur, they are likely due to ingestion of raw and unripe elderberries, or seeds, leaves, and other plant parts. Due to cyanogenic glycosides, these may cause nausea, vomiting, severe diarrhea, weakness, dizziness, numbness, and stupor. Cooking eliminates the toxin.
Gastrointestinal
...Orally, nausea and vomiting have been reported after consuming a specific elderberry and echinacea product
Vogel Bioforce AG) (95650). However, it is unclear if this was due to the elderberry or Echinacea contained in the product.
Raw and unripe elderberries, and the seeds, leaves, and other elder tree parts might cause nausea, vomiting, or severe diarrhea due to cyanogenic glycosides (17020,17021). Cooking eliminates the toxin.
Hepatic ...In one case report, a 60-year-old female with underlying autoimmune disease presented with autoimmune hepatitis after taking elderberry at an unknown dose for several years. The patient presented with nausea, jaundice, abdominal pain, and abdominal distention. Liver function tests returned to baseline 4 weeks after initiating treatment with prednisone 40 mg daily and discontinuing elderberry (110123).
Immunologic ...Elder tree pollen might cause an allergic reaction characterized by rhinitis and dyspnea in some patients who are allergic to grass pollen. These patients might also experience an allergic reaction to elderberry extracts (11095).
Neurologic/CNS ...Raw and unripe elderberries might cause weakness, dizziness, numbness, and stupor due to cyanogenic glycosides (17020,17021). Cooking eliminates the toxin.
General
...Orally, reishi mushroom is generally well tolerated.
Most Common Adverse Effects:
Orally: Dizziness, dry mouth, itching, nausea, rash, and stomach upset.
Dermatologic ...Orally, reishi mushroom can cause itching, rash, and other skin reactions (12,5479).
Gastrointestinal ...Orally, reishi mushroom can cause dryness of the mouth, throat, or nasal cavity, nausea, stomach upset, and, more rarely, diarrhea (12,70779,91438,108309).
Hematologic ...Orally, reishi mushroom can cause nosebleed and bloody stools (12,91438).
Hepatic ...One case of hepatotoxicity and one case of fatal fulminant hepatitis have been reported in patients who had used reishi mushroom powder for 1-2 months (70766). There is a case report of a 61-year-old male with hypereosinophilia associated with hepatic nodules following the use of reishi mushroom powder for about 2 months. Symptoms resolved after discontinuation of the product. Although these side effects were thought to be associated with the use of reishi mushroom powder, it is unclear if other factors played a role. The patient had been taking tegafur, gimeracil, and oteracil potassium for about 4 months following anterior resection for rectal adenocarcinoma but discontinued these agents and initiated reishi mushroom due to liver injury (108312).
Neurologic/CNS ...Orally, reishi mushroom can cause dizziness (91438). Other rare symptoms include insomnia and headache (70776,70779).
Pulmonary/Respiratory ...Respiratory allergy to reishi spores can occur (12,5479). Sore throat and runny nose have also been reported (70776,91438).
