Below is general information about the safety of the known ingredients contained in the product Lung Formula. Some ingredients may not be listed. This information does NOT represent a recommendation for or a test of this specific product as a whole.
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 and appropriately. Garlic has been used safely in clinical studies lasting up to 7 years without reports of significant toxicity (1873,4782,4783,4784,4785,4786,4787,4789,4790,4797)(4798,6457,6897,14447,96008,96009,96014,102016,102670,103479)(107238,107239,107352,108607,110722,111763).
POSSIBLY SAFE ...when used topically. Garlic-containing gels, lipid-soluble garlic extracts, garlic pastes, and garlic mouthwashes have been safely used in clinical research for up to 3 months (4766,4767,8019,15030,51330,51386). ...when used intravaginally. A vaginal cream containing garlic and thyme has been safely used nightly for 7 nights (88387).
POSSIBLY UNSAFE ...when raw garlic is used topically (585). Raw garlic might cause severe skin irritation when applied topically.
PREGNANCY: LIKELY SAFE
when used orally in amounts commonly found in foods (3319).
PREGNANCY: POSSIBLY UNSAFE
when used orally in medicinal amounts.
Garlic is reported to have abortifacient activity (11020). One study also suggests that garlic constituents are distributed to the amniotic fluid after a single dose of garlic (4828). However, there are no published reports of garlic adversely affecting pregnancy. In clinical research, garlic 800 mg daily was used during the third trimester of pregnancy with no reported adverse outcomes (9201,51626). There is insufficient reliable information available about the safety of topical garlic during pregnancy.
LACTATION: LIKELY SAFE
when used orally in amounts commonly found in foods (3319).
LACTATION: POSSIBLY UNSAFE
when used orally in amounts greater than those found in foods.
Several small studies suggest that garlic constituents are secreted in breast milk, and that nursing infants of mothers consuming garlic are prone to extended nursing (3319,4829,4830). There is insufficient reliable information available about the safety of topical garlic during lactation.
CHILDREN: POSSIBLY SAFE
when used orally and appropriately for up to 8 weeks.
Garlic extract 300 mg three times daily has been used with apparent safety for up 8 weeks in children ages 8-18 years (4796). There is insufficient reliable information available about the safety of garlic when used over longer durations or in higher doses.
CHILDREN: POSSIBLY UNSAFE
when raw garlic is used topically.
Raw garlic might cause severe skin irritation when applied topically (585,51210).
LIKELY SAFE ...when rose hip extract is used orally in the amounts found in foods. Rose hip extract has Generally Recognized as Safe (GRAS) status in the US (4912). ...when rose hip from Rosa canina is used orally and appropriately in medicinal amounts. A specific formulation of rose hip powder from Rosa canina (LitoZin/i-flex, Hyben Vital), taken in doses of up to 2.5 grams (5 capsules) twice daily, has been safely used for up to 6 months (17416,71641,71646,71658,71660,71661,104557). Rose hip powder from Rosa canina, 40 grams daily mixed in apple juice, has been used safely for up to 6 weeks (18104). Rose hip powder from Rosa canina, 500 mg twice daily for 20 days, has also been safely used (97938).
POSSIBLY SAFE ...when rose hip from Rosa damascena is used orally and appropriately in medicinal amounts. Rose hip extract from Rosa damascena has been used safely in doses of 200 mg every 6 hours for 3 days (104555). There is insufficient reliable information available about the safety of medicinal amounts of rose hip from other Rosa species. There is also insufficient reliable information available about the safety of rose hip when used topically.
PREGNANCY AND LACTATION:
There is insufficient reliable information available about the safety of rose hip when used orally or topically in medicinal amounts; avoid using in amounts greater than those found in foods.
LIKELY SAFE ...when used orally in amounts typically found in foods. Rosemary has Generally Recognized as Safe (GRAS) status in the US (4912).
POSSIBLY SAFE ...when the leaf is used orally and appropriately in medicinal amounts (18). Powdered rosemary leaf has been used with apparent safety as a single dose of up to 1.5 grams (18246,91731) or at a dose of 1-4 grams daily for up to 8 weeks (91727,98536,105327,109561). ...when the essential oil is used topically and appropriately for up to 7 months (5177,91729,109560). ...when the essential oil is used by inhalation as aromatherapy, short-term (7107,18323,105324,109559).
LIKELY UNSAFE ...when the essential oil or very large quantities of rosemary leaf are used orally. Ingestion of undiluted rosemary oil or very large quantities of rosemary leaf can cause serious adverse effects (18,515).
PREGNANCY: POSSIBLY UNSAFE
when used orally in medicinal amounts.
Rosemary might have uterine and menstrual flow stimulant effects (4,12,18), and might increase metabolism of estradiol and estrone (18331); avoid using. There is insufficient reliable information available about the safety of rosemary when used topically during pregnancy.

Below is general information about the interactions of the known ingredients contained in the product Lung Formula. Some ingredients may not be listed. This information does NOT represent a recommendation for or a test of this specific product as a whole.
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).
|
Garlic may have antiplatelet effects and may increase the risk of bleeding if used with anticoagulant or antiplatelet drugs.
Details
|
Theoretically, taking garlic with antidiabetes drugs might increase the risk of hypoglycemia.
Details
|
Theoretically, taking garlic with antihypertensive drugs might increase the risk of hypotension.
Details
|
Theoretically, garlic might decrease levels and effects of atazanavir.
Details
In a case report, a patient consuming six stir-fried garlic cloves three times weekly developed suboptimal atazanavir levels and increases in HIV viral load. While the exact cause of this interaction is unclear, there is speculation that garlic might decrease the intestinal absorption of atazanavir or increase its metabolism by inducing cytochrome P450 3A4 (CYP3A4) (88388). Until more is known, advise patients not to consume large amounts of garlic while taking atazanavir.
|
Garlic might increase levels of drugs metabolized by CYP2E1.
Details
Clinical research suggests garlic oil can inhibit the activity of CYP2E1 by 39% (10847). Use garlic oil cautiously in patients taking drugs metabolized by these enzymes.
|
Theoretically, garlic products containing allicin might induce intestinal CYP3A4 and inhibit hepatic CYP3A4. This may increase or decrease levels of drugs metabolized by CYP3A4.
Details
Some human research suggests that garlic may induce INTESTINAL CYP3A4, reducing levels of drugs metabolized by this enzyme. This is primarily based on a study showing that taking a specific allicin-containing garlic product (GarliPure Maximum Allicin Formula, Natrol Inc.) twice daily for 3 days reduces saquinavir levels by approximately 50%. It is speculated that the allicin constituent induced CYP3A4 in the gut mucosa (7027,93578). Another study shows that giving docetaxel intravenously, bypassing the CYP3A4 enzymes in the gut mucosa, along with the same specific garlic product for 12 consecutive days, does not affect docetaxel levels (17221). Conversely, there is concern that garlic may inhibit HEPATIC CYP3A4. In a single case report, increased tacrolimus levels and liver injury occurred in a liver transplant patient after taking a specific garlic supplement (Garlicin Cardio, Nature's Way) at up to three times the manufacturer recommended dose for 7 days (96010). Several other studies have evaluated the impact of other garlic formulations on CYP3A4 substrates and have found no effect. Most of the products in these studies provided little or no allicin (10335,10847,15031,94506).
|
Theoretically, garlic might decrease levels of isoniazid.
Details
Animal research suggests that an aqueous extract of garlic reduces isoniazid levels by about 65%. Garlic reduced the maximum concentration (Cmax) and area under the curve (AUC), but not the half-life, of isoniazid. This suggests that garlic extract might inhibit isoniazid absorption across the intestinal mucosa (15031); however, the exact mechanism of this potential interaction is not known.
|
Theoretically, garlic products containing allicin might decrease levels of PIs.
Details
Protease inhibitors are metabolized by cytochrome P450 3A4 (CYP3A4) isoenzymes. There is concern that garlic products containing allicin might induce intestinal CYP3A4, reducing plasma levels of protease inhibitors. This is primarily based on a study showing that taking a specific garlic product (GarliPure Maximum Allicin Formula, Natrol Inc.) twice daily for 3 days reduces levels of saquinavir, a PI, by approximately 50%. It is speculated that the allicin constituent induce CYP3A4 in the gut mucosa (7027,93578). Several studies have evaluated the impact of other garlic formulations on CYP3A4 substrates and have found no effect. Most of the products in these studies provided little or no allicin (10335,10847,15031,94506).
|
Theoretically, garlic containing allicin might decrease levels of saquinavir.
Details
Saquinavir is a substrate of cytochrome P450 3A4 (CYP3A4) isoenzymes. There is concern that garlic products containing allicin might induce intestinal CYP3A4 and cause subtherapeutic levels of saquinavir. This is primarily based on a pharmacokinetic study showing that taking a specific garlic product (GarliPure Maximum Allicin Formula, Natrol Inc.) twice daily for 3 days reduces saquinavir levels by approximately 50%. It is speculated that the allicin constituent induces CYP3A4 in the gut mucosa (7027,93578). Several pharmacokinetic studies have evaluated the impact of other garlic formulations on CYP3A4 substrates and have found no effect. Most of the products in these studies provided little or no allicin (10335,10847,15031,94506). Until more is known about this potential interaction, use garlic containing allicin cautiously in patients taking saquinavir.
|
Theoretically, taking garlic with sofosbuvir might decrease its effectiveness.
Details
Animal research in rats shows that giving aged garlic extract 120 mg/kg orally daily for 14 days decreases the area under the concentration time curve (AUC) after a single sofosbuvir dose of 40 mg/kg by 36%, increases the clearance by 63%, and decreases the plasma concentrations at 1 and 8 hours by 35% and 58%, respectively. This interaction is hypothesized to be due to induction of intestinal P-glycoprotein expression by garlic (109524).
|
Theoretically, garlic might increase levels of tacrolimus.
Details
In one case report, a liver transplant patient taking tacrolimus experienced increased tacrolimus levels and liver injury after taking a specific garlic supplement (Garlicin Cardio, Nature's Way) at up to three times the manufacturer recommended dose for 7 days. It is speculated that garlic inhibited hepatic cytochrome P450 3A4 (CYP3A4), which increased plasma levels of tacrolimus (96010).
|
Theoretically, garlic might increase the risk of bleeding with warfarin.
Details
Raw garlic and a variety of garlic extracts have antiplatelet activity and can increase prothrombin time (586,616,1874,3234,4366,4802,4803,51397). In addition, there is a report of two patients who experienced an increase in a previously stabilized international normalized ratio (INR) with concomitant garlic and warfarin use (51228,51631). However, this report has been subsequently debated due to limited clinical information. Other clinical studies have not identified an effect of garlic on INR, warfarin pharmacokinetics, or bleeding risk (15032,16416). More evidence is needed to determine the safety of using garlic with warfarin.
|
Theoretically, the antioxidant effects of rose hip might reduce the effectiveness of alkylating agents but might also reduce the oxidative damage caused by certain alkylating agents.
Details
Rose hip contains vitamin C. The use of antioxidants like vitamin C during chemotherapy is controversial. There is concern that antioxidants could reduce the activity of chemotherapy drugs that generate free radicals, such as cyclophosphamide, chlorambucil, carmustine, busulfan, and thiotepa (391). In contrast, some researchers theorize that antioxidants might make chemotherapy more effective by reducing oxidative stress that could interfere with apoptosis (cell death) of cancer cells (14012,14013). Further, some animal research suggests that the antioxidant effects of rose hip might attenuate cyclophosphamide-induced testicular toxicity (111413). More evidence is needed to determine what effect, if any, antioxidants found in rose hip, such as vitamin C, have on the effectiveness and adverse effects of chemotherapy.
|
Theoretically, rose hip might increase the amount of aluminum absorbed from aluminum compounds.
Details
Rose hip contains vitamin C. Theoretically, vitamin C increases the absorption of aluminum. Concomitant use might increase aluminum absorption, but the clinical significance of this is unknown (3046). Administer rose hip two hours before or four hours after antacids.
|
Theoretically, rose hip might reduce the effectiveness of anticoagulant or antiplatelet drugs.
Details
In vitro and animal research suggests that a constituent of rose hip, rugosin E, can induce platelet aggregation (71653). This has not been shown in humans. Theoretically, concomitant use of rose hip might reduce the effectiveness of antiplatelet or anticoagulant drugs.
|
Theoretically, the antioxidant effects of rose hip might reduce the effectiveness of antitumor antibiotics.
Details
Rose hip contains the antioxidant vitamin C. There is concern that antioxidants might reduce the activity of chemotherapy drugs that generate free radicals, such as antitumor antibiotics (391). In contrast, other researchers theorize that antioxidants might make antitumor antibiotic chemotherapy more effective by reducing oxidative stress that could interfere with apoptosis (cell death) of cancer cells (14012,14013). More evidence is needed to determine what effects, if any, antioxidants such as vitamin C have on antitumor antibiotic chemotherapy.
|
Theoretically, rose hip might reduce the clearance of aspirin; however, its vitamin C content is likely too low to produce clinically significant effects.
Details
Rose hip contains vitamin C. It has been suggested that acidification of the urine by vitamin C can decrease the urinary excretion of salicylates, increasing plasma salicylate levels (3046). However, short-term use of up to 6 grams daily of vitamin C does not seem to affect urinary pH or salicylate excretion (10588,10589). The vitamin C content of rose hip is typically about 500 mg per 100 grams. Thus, a clinically significant interaction between rose hip and aspirin is unlikely.
|
Theoretically, rose hip might increase blood levels of estrogens.
Details
Rose hip contains vitamin C. Increases in plasma estrogen levels of up to 55% have occured under some circumstances when vitamin C is taken concurrently with oral contraceptives or hormone replacement therapy, including topical products (129,130,11161). It is suggested that vitamin C prevents oxidation of estrogen in the tissues, regenerates oxidized estrogen, and reduces sulfate conjugation of estrogen in the gut wall (129,11161). When tissue levels of vitamin C are high, these processes are already maximized and supplemental vitamin C does not have any effect on estrogen levels. However, increases in plasma estrogen levels may occur when women who are deficient in vitamin C take supplements (11161).
|
Theoretically, rose hip might increase blood levels of lithium.
Details
|
Theoretically, rose hip might reduce the effectiveness of warfarin; however, its vitamin C content is likely too low to produce clinically significant effects.
Details
Rose hip contains vitamin C. High doses of vitamin C may reduce the response to warfarin, possibly by causing diarrhea and reducing warfarin absorption (11566). This occurred in two people who took up to 16 grams daily of vitamin C, and resulted in decreased prothrombin time (9804,9806). Lower doses of 5-10 grams daily of vitamin C can also reduce warfarin absorption, but this does not seem to be clinically significant (9805,9806,11566,11567). The vitamin C content of rose hip is typically about 500 mg per 100 grams. Thus, a clinically significant interaction between rose hip and warfarin is unlikely.
|
Theoretically, rosemary may increase the risk of bleeding if used with anticoagulant or antiplatelet drugs.
Details
|
Theoretically, taking rosemary with antidiabetes drugs might increase the risk of hypoglycemia.
Details
Animal research shows that rosemary extract can decrease blood glucose levels in diabetic models (71821,71923). However, research in humans is conflicting. Although rosemary powder decreased blood glucose levels in healthy adults (105327), no change in blood glucose levels was seen in adults with type 2 diabetes, most of whom were taking antidiabetes drugs (105323,105327).
|
Theoretically, rosemary might have additive effects with salicylate-containing drugs such as aspirin.
Details
Rosemary is reported to contain salicylates (18330).
|
Theoretically, rosemary might have additive effects with salicylate-containing drugs such as choline magnesium trisalicylate.
Details
Rosemary is reported to contain salicylate (18330).
|
Theoretically, rosemary might decrease the levels and clinical effects of CYP1A1 substrates.
Details

Theoretically, rosemary might decrease the levels and clinical effects of CYP1A2 substrates.
Details
|
Theoretically, rosemary might have additive effects with salicylate-containing drugs such as salsalate.
Details
Rosemary is reported to contain salicylate (18330).
|
Theoretically, concurrent use of anticholinergic drugs and thyme essential oil might reduce the effects of anticholinergic drugs.
Details
In vitro evidence suggests that thyme essential oil and specific essential oil constituents like thymohydroquinone and carvacrol can inhibit acetylcholinesterase (AChE) (78155). However, this effect has not been observed in humans.
|
Theoretically, thyme leaf extract might have additive effects with anticoagulant or antiplatelet drugs.
Details
|
Theoretically, concurrent use of cholinergic drugs and thyme essential oil might cause additive cholinergic effects.
Details
In vitro evidence suggests that thyme essential oil and specific essential oil constituents like thymohydroquinone and carvacrol can inhibit acetylcholinesterase (AChE) (78155). However, this effect has not been observed in humans.
|
Theoretically, thyme might competitively inhibit the effects of estrogen replacement therapy.
Details
In vitro research shows that thyme has estrogen receptor-binding activity and phytoestrogen content (3701). However, this effect has not been observed in humans.

Below is general information about the adverse effects of the known ingredients contained in the product Lung Formula. 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, 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, garlic is generally well tolerated.
Topically, garlic seems to be well tolerated. Intravenously, there is insufficient reliable information available about adverse effects.
Most Common Adverse Effects:
Orally: Abdominal pain, body odor, flatulence, malodorous breath, and nausea. Allergic reactions in sensitive individuals.
Topically: Burns and dermatitis with fresh garlic.
Serious Adverse Effects (Rare):
Orally: Some case reports raise concerns about increased risk of bleeding with garlic.
Dermatologic
...Orally, garlic may cause pruritus (51316,51474,107239), flushing, and acne (107239).
Oral intake of a specific garlic product containing allicin (Allimax) has been associated with a case of pruritic rash (51474). Enteric-coated garlic tablets standardized to 1.5% allicin have also been associated with a case of pruritus (51316). Garlic has also been associated with a case of superficial pemphigus in a 49-year-old male with type 2 diabetes (51564). Garlic-induced oral ulcers have also been reported (51467).
Topically, garlic may cause contact dermatitis and urticaria (4833,5004,12635,51258,51265,51375,51403,51412,51459,51483)(51511,51512,51530,51616,51617,51618,111769), as well as contact cheilitis (51384). Fresh garlic may be more likely to elicit a reaction than garlic extract. Most reactions have resolved following withdrawal of garlic therapy. In one case report, applying crushed garlic on the neck to help ease a sore throat resulted in an itchy, burning, erythematous lesion in a young female patient. The lesion healed after one week of treatment with topical antibiotics, steroids, and antihistamine ointments (88390). Cases of occupational eczema or dermatitis have been reported in cooks (51303,51210), food handlers (51292), and caterers (51304). According to one case report, dermatitis appeared in chefs exposed to garlic (15033). Treatment with acitretin 25 mg daily or topical psoralen-ultraviolet A (PUVA) for 12 weeks proved effective in mitigating the symptoms. A 34-year-old female with a history of hand dermatitis and paronychia had a worsening of these conditions after peeling raw garlic. She had a positive skin patch test to fresh, raw garlic but not to any other tested allergens, and the conditions resolved when she avoided contact with garlic (105528). Topically, garlic may also cause chemical burns, usually within 12 hours of application. Second- and third-degree chemical burns have been reported in adults, children, and infants exposed to topical garlic, often as an unintended consequence of using garlic medicinally on the skin (585,4832,51226,51230,51252,51281,51377,51418,51468,51495,51536)(51558,51576,51577,88409,96006). A case of painful blisters on the soles of the feet of a 23-year-old Chinese female has been attributed to chemical burns caused by applying crushed raw garlic for 3 hours (51440). Topically, garlic may also cause hyperpigmentation, ulcers, necrotic lesions, facial flushing, and local irritation (4832,15030,51268,51269,108606). In one case report, applying crushed raw garlic to the palatal mucosa for several minutes to relieve mouth pain resulted in a chemical burn that produced a 3 cm necrotic ulcer in an adult female with trigeminal neuralgia (108606).
Gastrointestinal
...Orally, dehydrated garlic preparations or raw garlic may cause malodorous breath (51438,51444), body odor (732,1873,4784,4793,4795,4798,9201,10787,42692,49769)(51269,51316,51467,51602), abdominal pain or fullness, anorexia, diarrhea, constipation, flatulence, belching, heartburn, nausea, unpleasant taste, reflux, and bowel obstruction (1884,6457,6897,9201,49769,51269,51343,51380,51438,51442)(51450,51457,51466,51471,51474,51520,51593,51602,51623,88398)(88405,111766).
Large quantities of garlic may damage the gastrointestinal tract. In one case report, a patient taking garlic for hypertension reported odynophagia and retrosternal pain after taking garlic without any water the previous day. An esophageal lesion 3 cm in length was detected upon endoscopy. The symptoms resolved 3 days after starting a liquid diet and taking lansoprazole 30 mg twice daily and sucralfate four times daily (88389). One case of bowel obstruction was reported in a 66-year-old male who ingested an entire garlic bulb (51525). Esophageal perforation has been reported in at least 17 individuals who consumed entire garlic cloves. In one case the perforation led to mediastinitis and death (102672).
Garlic has also been associated with eosinophilic infiltration of the gastrointestinal tract. In one case report a 42-year-old female presented with symptoms of eosinophilic gastroenteritis, which included pollinosis, asthma, diarrhea, heart burn, peripheral eosinophilia, and urticaria. After stopping use of garlic and sesame, the patient improved (51441). In a case report of eosinophilic esophagitis, garlic was determined to be the causative agent in a patient with long-standing gastrointestinal symptoms. The patient had attempted to treat upper gastrointestinal symptoms as gastrointestinal reflux disease without success for many years. Skin prick testing showed a positive reaction to garlic, of which the patient noted frequent consumption. Marked symptom improvement was noted within 3 weeks of garlic avoidance (88393).
Intravenously, garlic 1 mg/kg of body weight daily diluted into 500 mL saline and administered over 4 hours has been reported to cause abdominal discomfort, vomiting, diarrhea, nausea, anorexia, flatulence, weight loss, and garlicky body odor (51462).
Clinical research suggests that patients with metabolic syndrome taking 1600 mg of powdered garlic by mouth daily for 3 months may experience improved intestinal transit time when compared with placebo, suggesting that garlic powder may reduce symptoms of constipation (110722).
Genitourinary ...Orally, garlic might cause dysuria, hematuria, or polyuria (51438,51450,51467,113618). In one case, an older male with high dietary and supplemental garlic intake at doses of 300-5400 mg daily for 3-4 years developed severe hematuria with clots after undergoing a minimally invasive prostate procedure (113618).
Hematologic
...Oral use of dietary garlic or supplements containing garlic has caused platelet dysfunction, increased fibrinolytic activity, prolonged bleeding time, retrobulbar hemorrhage (bleeding behind the eye) postoperative bleeding, and spinal epidural hematoma (586,587,4801,4802,11325,51397,51473,51491,51532,51534)(51570,51584,51593,51594,113618).
Also, a case of kidney hematoma following extracorporeal shock-wave lithotripsy (SWL) has been reported in a patient with nephrolithiasis who took aged garlic (51630). A case of increased bleeding time that complicated epistaxis management has been reported in a patient taking garlic, aspirin, and milk thistle (51426).
Intravenously, garlic has been associated with the development of thrombophlebitis at the injection site (51462).
Immunologic
...There is a case report of an immediate sensitivity reaction to oral raw garlic, resulting in wheals, in a 31-year-old female.
The patient did not react to cooked garlic, and skin prick tests showed allergy only to raw garlic (96015). Researchers note that at least some allergens in raw garlic are heat labile (88392,96012,96015). This suggests that consuming cooked rather than raw garlic may help avoid this reaction in patients allergic to raw garlic. However, different people react to different allergens in garlic. At least some of these allergens are heat stable (96012). While rare, garlic-induced anaphylaxis has been reported (88392,96012).
Topically, allergic contact dermatitis has been reported in case reports (51406,51498,51510,51519,51560).
Musculoskeletal ...Orally, garlic has been associated with individual cases of gout and low back pain (51474,51467), but it is not clear if these adverse events can be attributed to garlic.
Neurologic/CNS ...Orally, dizziness, insomnia, headaches, diaphoresis, fever, chills, somnolence, increased appetite, euphoria, and weight loss have been reported with garlic (15032,42692,51316,51467,51471,51520). In one case, the smell of garlic was identified as a trigger for migraines in a 32-year-old female. The subject reported fortification spectra along with visual spots for a few seconds followed by instantaneous biparietal, crushing level (10/10) headaches upon exposure to the scent of garlic or onion (88404).
Pulmonary/Respiratory ...Garlic exposure, most notably in occupational settings, may cause asthma and other symptoms such as sneezing, nasal obstruction, rhinorrhea, and sinusitis (40661,51218). A case of minor hemoptysis has been reported for one patient with cystic fibrosis following intake of garlic capsules orally once daily for 8 weeks (51438). A 77-year-old female developed pneumonia related to the intake of one whole black garlic clove daily. The cloves were prepared by heating a whole garlic bulb in a pot for one month. Symptoms included dyspnea and coughing, and test results were positive for lymphocyte-induced stimulation by black garlic and raw garlic. The patient required treatment with oral steroids and was told to avoid garlic (96011).
General
...Orally, rose hip from Rosa canina is well tolerated.
Rose hip from Rosa damascena also seems to be well tolerated. A thorough evaluation of safety outcomes has not been conducted for rose hip derived from other species.
Most Common Adverse Effects:
Orally: Flatulence, loose stools.
Dermatologic ...Orally, one case of mild urticaria has been reported in a clinical trial for a patient taking a specific rose hip powder product (LitoZin/i-flex, Hyben Vital) 2. 5 grams twice daily (71646).
Gastrointestinal
...Orally, gastrointestinal reactions have been reported.
These include abdominal cramps, acid reflux, constipation, diarrhea, flatulence, nausea, vomiting, gastrointestinal obstruction, esophagitis, heartburn, acid reflux, and water brash. However, in most cases, these adverse effects occurred at the same frequency in patients taking placebo (15,18104,71641,71646,97938).
Rose hip powder is a source of vitamin C. Osmotic diarrhea and gastrointestinal upset have been reported with doses of vitamin C greater than the tolerable upper intake level (UL) of 2000 mg daily (4844). However, most rose hip products contain only 500 mg of vitamin C per 100 grams.
Genitourinary ...Orally, a few mild cases of frequent voiding have been reported in clinical trials. However, the frequency of occurrence does not seem to differ from those taking placebo (71641,71646).
Immunologic ...When inhaled in the workplace, rose hip dust has caused mild to moderate anaphylaxis (6).
Neurologic/CNS ...Orally, vertigo and headache have been reported rarely (97938).
Ocular/Otic ...A case of keratoconjunctivitis secondary to contact with rose hip has been reported. The adverse effect was attributed to irritant hairs found on the fruit of rose hip. Symptoms resolved after treatment with topical prednisolone 1% eye drops (71642).
General ...Orally, rosemary seems to be well tolerated when used in appropriate medicinal amounts. Undiluted rosemary oil or very large quantities of rosemary leaf should not be consumed. Topically and as aromatherapy, rosemary seems to be well tolerated.
Dermatologic ...Topically, rosemary use can lead to photosensitivity, erythema, dermatitis, and cheilitis in hypersensitive individuals (4,6).
Immunologic
...Topically, allergic reactions can occur.
When used in the mouth, lip and gum edema have occurred (101173). When used on the skin, allergic contact dermatitis has occurred, likely due to the constituent carnosol (71715,71924,71926).
Rosemary might also cause occupational asthma. A case of occupational asthma caused by several aromatic herbs including thyme, rosemary, bay leaf, and garlic has been reported. The diagnosis was confirmed by inhalation challenges. Although all of the herbs caused immediate skin reactivity, a radioallergosorbent test (RAST) showed that garlic was the most potent allergen by weight, with rosemary and the other herbs showing less reactivity (783).
Neurologic/CNS ...Orally, the undiluted oil, as well as the camphor constituent of rosemary, might cause seizures (4,5,6,12868).
General
...Orally, thyme is well tolerated when used in food and seems to be well tolerated when used medicinally.
Topically, thyme seems to be generally well tolerated.
Most Common Adverse Effects:
Orally: Allergic reactions, diarrhea, dizziness, headache, heartburn, nausea, or vomiting.
Topically: Contact dermatitis and skin irritation.
Dermatologic ...Topically, thyme, thyme oil, or the constituent thymol can cause contact dermatitis and skin irritation (13463,78252,78362,78384,77982,78154,78310,78313,78384). In one study of 100 patients with contact allergies, 5% were attributed to thyme oil as an allergen contained in wound dressings (78362). Toothpastes containing thymol have been associated with cheilitis and glossitis (13463).
Gastrointestinal
...Orally, thyme and thyme oil may cause heartburn, nausea, vomiting, stomach upset, or diarrhea (13557,94033).
In a clinical study, two patients using extracts of thyme herb and ivy leaves experienced temporary stomach ache and mild nausea (78181).
Intravaginally, cream containing thyme and garlic has been associated with reports of nausea and vomiting in one clinical study (88387). It is not clear if these adverse effects were associated with thyme, garlic, or the combination.
Genitourinary ...Intravaginally, cream containing thyme and garlic has been associated with reports of vaginal dryness and vaginal irritation in one clinical study (88387). It is not clear if these adverse effects were associated with thyme, garlic, or the combination.
Immunologic ...Orally, thyme can cause allergic reactions; however, this is uncommon (13463). Allergic reactions to thyme might be more common in people who are also allergic to oregano and other Lamiaceae species (3808).
Neurologic/CNS ...Orally, thyme may case headache or dizziness (94033).
Pulmonary/Respiratory ...By inhalation, occupational exposure to thyme dust can cause acute airway obstruction (783,13463,13464,77982,78098).
