Below is general information about the safety of the known ingredients contained in the product Trauma Drops. 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 in amounts commonly found in foods. Arnica has Generally Recognized As Safe (GRAS) status for use as a food flavoring in the US (4912). However, Canadian regulations do not allow its use as a food ingredient (12). ...when used orally in homeopathic dilutions of 30C and up to 5C (19110,19111,19117,19124,19126,96769). ...when used topically on unbroken skin, short-term (12).
LIKELY UNSAFE ...when used orally or when applied topically to broken skin. Arnica is considered poisonous and has caused severe or fatal poisonings (5). Arnica can cause gastroenteritis, muscle paralysis, bleeding, arrhythmia, hypertension, shortness of breath, nausea and vomiting, multi-organ failure, and death (4,5,17,104,19101,19102,19103,19104,19105,19106,19107,19108).
PREGNANCY AND LACTATION: LIKELY UNSAFE
when used orally or topically; avoid using (12).
LIKELY SAFE ...when the flower preparations are used orally or topically and appropriately (4,19779,36931,39503,93552,93557,96647,105088).
PREGNANCY: LIKELY UNSAFE
when used orally; contraindicated due to spermatocide, antiblastocyst, and abortifacient effects.
There is insufficient reliable information available about the safety of calendula when used topically during pregnancy (4).
LACTATION:
Insufficient reliable information available; avoid using.
LIKELY SAFE ...when used orally and appropriately. St. John's wort extracts in doses up to 900 mg daily seem to be safe when used for up to 12 weeks (3547,3550,4835,5096,6400,6434,7047,13021,13156,13157)(14417,76143,76144,89666,89669,95510). Some evidence also shows that St. John's wort can be safely used for over one year (13156,13157,76140), and may have better tolerability than selective serotonin reuptake inhibitors (SSRIs) and tricyclic antidepressants (TCAs) (4897,76153,76143,104036).
POSSIBLY SAFE ...when used topically and appropriately. St. John's wort 0.5% extract seems to be safe when used once weekly for 4 weeks (110327). St. John's wort oil has been used with apparent safely twice daily for 6 weeks (110326). However, topical use of St. John's wort can cause photodermatitis with sun exposure (110318).
POSSIBLY UNSAFE ...when used orally in large doses. St. John's wort extract can be unsafe due to the risk of severe phototoxic skin reactions. Taking 2-4 grams of St. John's wort extract (containing hypericin 5-10 mg) daily appears to increase the risk of photosensitivity (758,4631,7808).
PREGNANCY: POSSIBLY UNSAFE
when used orally.
Preliminary population research has found that taking St. John's wort while pregnant is associated with offspring that develop neural tube, urinary, and cardiovascular malformations. Subgroup analyses suggest that these risks may be higher when taking St. John's wort during the first trimester when compared with the second or third trimester. However, more research is needed to confirm these findings (106052). Animal-model research also shows that constituents of St. John's wort might have teratogenic effects (9687,15122). Until more is known, St. John's wort should not be taken during pregnancy.
LACTATION: POSSIBLY UNSAFE
when used orally.
Nursing infants of mothers who take St. John's wort have a greater chance of experiencing colic, drowsiness, and lethargy (1377,15122,22418); avoid using.
CHILDREN: POSSIBLY SAFE
when used orally, and appropriately, short-term.
St. John's wort extracts in doses up to 300 mg three times daily seem to be safe when used for up to 8 weeks in children aged 6-17 years (4538,17986,76110).
Below is general information about the interactions of the known ingredients contained in the product Trauma Drops. 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, arnica might have additive effects with anticoagulant and antiplatelet drugs. Homeopathic arnica preparations are unlikely to have this interaction.
 Details
In vitro evidence shows that sesquiterpene lactones in arnica flowers can decrease platelet aggregation (104). However, this effect has not been reported in humans.
|
Theoretically, calendula might have additive effects when used with CNS depressants, although this appears to be unlikely.
Details
|
St. John's wort increases the clearance of alprazolam and decreases its effects.
Details
Alprazolam, which is used as a probe for cytochrome P450 3A4 (CYP3A4) activity, has a two-fold increase in clearance when given with St. John's wort. St. John's wort reduces the half-life of alprazolam from 12.4 hours to 6 hours (10830).
|
St. John's wort may increase the clearance of ambristentan and decrease its effects.
Details
Clinical research in healthy volunteers shows that taking St. John's wort 900 mg daily decreases the area under the concentration-time curve of ambrisentan 5 mg by 17% to 26%. Ambrisentan clearance was increased by 20% to 35% depending on CYP2C19 genotype. However, these small changes are unlikely to be clinically significant (99511).
|
St. John's wort might have additive phototoxic effects with aminolevulinic acid.
Details
Concomitant use with St. John's wort extract may cause synergistic phototoxicity. Delta-aminolevulinic acid can cause a burning erythematous rash and severe swelling of the face, neck, and hands when taken with St. John's wort (9474).
|
St. John's wort might decrease the levels and clinical effects of boceprevir.
Details
Boceprevir increases the maximum concentration and concentration at 8 hours of the St. John's wort constituent, hypericin, by approximately 30%. However, St. John's wort does not significantly change the area under the concentration-time curve or maximum plasma concentration of boceprevir 800 mg three times daily in healthy adults (95507,96552).
|
St. John's wort might reduce the levels and effects of bupropion.
Details
Clinical research shows that taking St. John's wort 325 mg three times daily for 14 days along with bupropion reduces the area under the concentration-time curve by approximately 14% and increases the clearance of bupropion by approximately 20%. This effect is attributed to the induction of cytochrome P450 2B6 (CYP2B6) by St. John's wort (89662).
|
St. John's wort might increase the levels and effects of clopidogrel.
Details
Taking St. John's wort with clopidogrel seems to increase the activity of clopidogrel. In clopidogrel non-responders, taking St. John's wort seems to induce metabolism of clopidogrel to its active metabolite by cytochrome P450 enzymes 3A4 and 2C19. This leads to increased antiplatelet activity (13038,89671,96552). Theoretically, this might lead to an increased risk of bleeding in clopidogrel responders.
|
St. John's wort might decrease the levels and clinical effects of clozapine.
Details
A case report describes a female with schizophrenia controlled on clozapine who had a return of symptoms when she started taking St. John's wort. The plasma concentration of clozapine was reduced, likely because its clearance was increased due to induction of the cytochrome P450 enzymes 3A4, 1A2, 2C9, and 2C19 by St. John's wort (96552).
|
St. John's wort increases the clearance of contraceptive drugs and reduces their clinical effects.
Details
Females taking St. John's wort and oral contraceptives concurrently should use an additional or alternative form of birth control. St. John's wort can decrease norethindrone and ethinyl estradiol levels by 13% to 15%, resulting in breakthrough bleeding, irregular menstrual bleeding, or unplanned pregnancy (11886,11887,13099). Bleeding irregularities usually occur within a week of starting St. John's wort and regular cycles usually return when St. John's wort is discontinued. Unplanned pregnancy has occurred with concurrent use of oral contraceptives and St. John's wort extract (9880). St. John's wort is thought to induce the cytochrome P450 1A2 (CYP1A2), 2C9 (CYP2C9), and 3A4 (CYP3A4) enzymes, which are responsible for metabolism of progestins and estrogens in contraceptives (1292,7809,9204).
|
St. John's wort reduces the levels and clinical effects of cyclosporine.
Details
Concomitant use can decrease plasma cyclosporine levels by 30% to 70% (1234,4826,4831,4834,7808,9596,10628,96552). Using St. John's wort with cyclosporine in patients with heart, kidney, or liver transplants can cause subtherapeutic cyclosporine levels and acute transplant rejection (1234,1293,1301,6112,6435,7808,9596). This interaction has occurred with a St. John's wort extract standardized to 0.3% hypericin and dosed at 300-600 mg per day (6435,10628). Withdrawal of St. John's wort can result in a 64% increase in cyclosporine levels (1234,4513,4826,4831,4834). St. John's wort induces cytochrome P450 3A4 (CYP3A4) and the multi-drug transporter, P-glycoprotein/MDR-1, which increases cyclosporine clearance (1293,1340,9204,9596).
|
St. John's wort may increase the metabolism and reduce the levels of CYP1A2 substrates.
Details
|
St. John's wort may increase the metabolism and reduce the levels of CYP2B6 substrates.
Details
Clinical research shows that taking St. John's wort 325 mg three times daily for 14 days along with bupropion, a CYP2B6 substrate, reduces the area under the concentration-time curve by approximately 14% and increases the clearance of bupropion by approximately 20% (89662).
|
St. John's wort may increase the metabolism and reduce the levels of CYP2C19 substrates.
Details
Preliminary clinical research in healthy males shows that taking St. John's wort for 14 days induces CYP2C19 and increases metabolism of mephenytoin (Mesantoin). In patients with wild-type 2C19 (2C19*1/*1) metabolism was almost 4-fold greater in subjects who received St. John's wort compared to placebo. In contrast, patients with 2C19*2/*2 and *2/*3 genotypes did not demonstrate a similar increase in metabolism (17405). Theoretically, St. John's wort might increase metabolism of other CYP2C19 substrates.
|
St. John's wort may increase the metabolism and reduce the levels of CYP2C9 substrates.
Details
There is contradictory research about the effect of St. John's wort on CYP2C9. Some in vitro research shows that St. John's wort induces CYP2C9, but to a lesser extent than CYP3A4 (9204,10848,11889). St. John's wort also induces metabolism of the S-warfarin isomer, which is a CYP2C9 substrate (11890). Other research shows that St. John's wort 300 mg three times daily for 21 days does not significantly affect the pharmacokinetics of a single 400 mg dose of ibuprofen, which is also a CYP2C9 substrate (15546). Until more is known, use St. John's wort cautiously in patients who are taking CYP2C9 substrates.
|
St. John's wort increases the metabolism and reduces the levels of CYP3A4 substrates.
Details
|
St. John's wort reduces the levels and clinical effects of digoxin.
Details
St. John's wort can reduce the bioavailability, serum levels, and therapeutic effects of digoxin. Taking an extract of St. John's wort 900 mg, containing hyperforin 7.5 mg or more, daily for 10-14 days, can reduce serum digoxin levels by 25% in healthy people. St. John's wort is thought to affect the multidrug transporter, P-glycoprotein, which mediates the absorption and elimination of digoxin and other drugs (382,6473,7808,7810,9204,96552,97171). St. John's wort products providing less than 7.5 mg of hyperforin daily do not appear to affect digoxin levels (97171).
|
St. John's wort reduces the levels and clinical effects of docetaxel.
Details
Clinical research shows that taking a specific St. John's wort product (Hyperiplant, VSM) 300 mg three times daily for 14 days increases docetaxel clearance by about 14%, resulting in decreased plasma concentrations of docetaxel in cancer patients. This is most likely due to induction of cytochrome P450 3A4 (CYP3A4) by St. John's wort (89661).
|
Theoretically, St. John's wort may reduce the levels and clinical effects of fentanyl.
Details
Given that St. John's wort induces cytochrome P450 3A4 (CYP3A4) and P-glycoprotein, it is possible that concomitant use of St. John's wort with fentanyl will reduce plasma levels and analgesic activity of fentanyl (96552). However, some clinical research in healthy adults shows that taking St. John's wort (LI-160, Lichtwer Pharma) 300 mg daily for 21 days does not alter the pharmacokinetics or clinical effects of intravenous fentanyl (102868). It is unclear if these findings can be generalized to oral, intranasal, or transdermal fentanyl.
|
St. John's wort may increase the levels and clinical effects of fexofenadine.
Details
A single dose of St. John's wort decreases the clearance of fexofenadine and increases its plasma levels. However, the effect of St. John's wort on plasma levels of fexofenadine seems to be lost if dosing is continued for more than 2 weeks (9685). Patients taking fexofenadine and St. John's wort concurrently should be monitored for possible fexofenadine toxicity.
|
St. John's wort may reduce the levels and clinical effects of finasteride.
Details
St. John's wort reduces plasma levels of finasteride in healthy male volunteers due to induction of finasteride metabolism via cytochrome P450 3A4 (CYP3A4). The clinical significance of this interaction is not known (96552).
|
St. John's wort may reduce the levels and clinical effects of gliclazide.
Details
Taking St. John's wort decreases the half-life and increases clearance of gliclazide in healthy people (22431).
|
St. John's wort may increase the metabolism and reduce the effectiveness of atorvastatin, lovastatin, and rosuvastatin. However, it does not seem to affect pravastatin, pitavastatin, or fluvastatin.
Details
Concomitant use of St. John's wort can reduce plasma concentrations of the active simvastatin metabolite, simvastatin hydroxy acid, by 28%. St. John's wort induces intestinal and hepatic cytochrome P450 3A4 (CYP3A4) and intestinal P-glycoprotein/MDR-1, a drug transporter. This increases simvastatin clearance. It also increases the clearance of atorvastatin (Lipitor), lovastatin (Mevacor), and rosuvastatin (Crestor). St. John's wort does not seem to affect the plasma concentrations of pravastatin (Pravachol), pitavastatin (Livalo) or fluvastatin (Lescol), which are not substrates of CYP3A4 or P-glycoprotein (10627,96552,97171).
|
St. John's wort reduces the levels and clinical effects of imatinib.
Details
Taking St. John's wort 900 mg daily for 2 weeks reduces the bioavailability and half-life of a single dose of imatinib and decreases its serum levels by 30% in healthy volunteers. This is most likely due to induction of cytochrome P450 3A4 (CYP3A4) by St. John's wort, which increases clearance of imatinib (11888,96552).
|
St. John's wort may reduce the levels and clinical effects of indinavir.
Details
In healthy volunteers, taking St. John's wort concurrently with indinavir reduces plasma concentrations of indinavir by inducing metabolism via cytochrome P450 3A4 (CYP3A4) (96552). Theoretically, this could result in treatment failure and viral resistance.
|
St. John's wort reduces the levels and clinical effects of irinotecan.
Details
St. John's wort 900 mg daily for 18 days decreases serum levels of irinotecan by at least 50%. Clearance of the active metabolite of irinotecan, SN-38, is also increased, resulting in a 42% decrease in the area under the concentration-time curve (9206,97171). This is thought to be due to induction of cytochrome P450 3A4 (CYP3A4) by St. John's wort (7092,96552).
|
St. John's wort might reduce the levels and clinical effects of ivabradine.
Details
Taking St. John's wort 900 mg containing 7.5 mg of hyperforin daily for 14 days with a single dose of ivabradine causes a 62% reduction in plasma levels of ivabradine. This interaction is thought to be due to induction of cytochrome P450 3A4 (CYP3A4) by St. John's wort, increasing the metabolism of ivabradine (96552,97171).
|
St. John's wort reduces the levels and clinical effects of ketamine.
Details
Taking St. John's wort 300 mg three times daily for 14 days can decrease maximum serum levels of ketamine by around 66% and area under the concentration-time curve of ketamine by 58%. This is most likely due to induction of cytochrome P450 3A4 (CYP3A4) by St. John's wort (89663).
|
St. John's wort reduces the levels and clinical effects of mephenytoin.
Details
Preliminary clinical research in healthy males shows that taking St. John's wort for 14 days induces cytochrome P450 2C19 (CYP2C19) and significantly increases metabolism of mephenytoin (Mesantoin). In people with wild-type 2C19, metabolism was almost 4-fold greater in subjects who received St. John's wort compared to placebo. In contrast, patients with 2C19*2/*2 and *2/*3 genotypes did not demonstrate a similar increase in metabolism (17405).
|
St. John's wort might reduce the levels and clinical effects of methadone.
Details
St. John's wort might decrease the effectiveness of methadone by reducing its blood concentrations. In one report, two out of four patients on methadone maintenance therapy for addiction experienced methadone withdrawal symptoms after taking St. John's wort 900 mg daily for a median of 31 days. There was a median decrease in blood methadone concentration of 47% (range: 19% to 60%) when compared to baseline (22419).
|
St. John's wort might reduce the levels and clinical effects of methylphenidate.
Details
St. John's wort might decrease the effectiveness of methylphenidate. In one report, an adult male, stabilized on methylphenidate for attention deficit-hyperactivity disorder (ADHD), experienced increased attention problems and ADHD symptoms after taking St. John's wort 600 mg daily for 4 months. ADHD symptoms improved when St. John's wort was discontinued (15544). The mechanism of this interaction is unknown.
|
St. John's wort decreases the levels and clinical effects of NNRTIs.
Details
St. John's wort increases the oral clearance of nevirapine (Viramune) by 35%. Subtherapeutic concentrations are associated with therapeutic failure, development of viral resistance, and development of drug class resistance. St. John's wort induces intestinal and hepatic cytochrome P450 3A4 (CYP3A4) and intestinal P-glycoprotein/MDR-1, a drug transporter (1290,1340,4837,96552).
|
St. John's wort decreases the levels and clinical effects of omeprazole.
Details
Taking St. John's wort, 300 mg orally three times daily for 14 days, reduces serum concentrations of omeprazole by inducing its metabolism via cytochrome P450 (CYP) 2C19 and 3A4. The reduction of omeprazole serum levels is dependent on CYP2C19 genotype, with reductions up to 50% in extensive metabolizers and 38% in poor metabolizers (22440,96552).
|
St. John's wort decreases the levels and clinical effects of oxycodone.
Details
St. John's wort can increase oxycodone metabolism by inducing cytochrome P450 3A4 (CYP3A4), reducing plasma levels and analgesic activity (96552).
|
St. John's wort decreases the levels and clinical effects of P-glycoprotein substrates.
Details
St. John's wort induces P-glycoprotein. P-glycoprotein is a carrier mechanism responsible for transporting drugs and other substances across cell membranes. When P-glycoprotein is induced in the gastrointestinal (GI) tract, it can prevent the absorption of some medications. In addition, induction of p-glycoprotein can decrease entry of drugs into the central nervous system (CNS) and decrease access to other sites of action (382,1340,7810,11722).
|
St. John's wort decreases the levels and clinical effects of phenobarbital.
Details
St. John's wort may increase the metabolism of phenobarbital. Plasma concentrations of phenobarbital should be monitored carefully. The dose of phenobarbital may need to be increased when St. John's wort is started and decreased when it is stopped (9204).
|
St. John's wort decreases the levels and clinical effects of phenprocoumon.
Details
St. John's wort appears to increase the metabolism of phenprocoumon (an anticoagulant that is not available in the US) by increasing the activity of the cytochrome P450 2C9 (CYP2C9) enzyme. This may result in decreases in the anticoagulant effect and international normalized ratio (INR) (9204).
|
St. John's wort decreases the levels and clinical effects of phenytoin.
Details
St. John's wort may increase the metabolism of phenytoin. Plasma concentrations of phenytoin should be monitored closely. The dose of phenytoin may need to be increased when St. John's wort is started and decreased when it is stopped (9204).
|
Theoretically, St. John's wort might increase the likelihood for photosensitivity reactions when used in combination with photosensitizing drugs.
Details
|
Theoretically, St. John's wort might decrease the levels and clinical effects of procainamide.
Details
Animal research shows that taking St. John's wort extract increases the bioavailability of procainamide, but does not increase its metabolism (14865). Whether this interaction is clinically significant in humans is not known.
|
St. John's wort reduces the levels and clinical effects of PIs.
Details
In healthy volunteers, St. John's wort can reduce the plasma concentrations of indinavir (Crixivan) by inducing cytochrome P450 3A4 (CYP3A4). This might result in treatment failure and viral resistance (1290,7808,96552). St. John's wort also induces P-glycoprotein, which can result in decreased intracellular protease inhibitor concentrations and increased elimination (9204).
|
Theoretically, St. John's wort might decrease the effectiveness of reserpine.
Details
Animal research shows that St. John's wort can antagonize the effects of reserpine (758).
|
St. John's wort decreases the levels and clinical effects of rivaroxaban.
Details
A small pharmacokinetic study in healthy volunteers shows that taking a single dose of rivaroxaban 20 mg after using a specific St. John's wort extract (Jarsin, Vifor SA) 450 mg orally twice daily for 14 days reduces the bioavailability of rivaroxaban by 24% and reduces rivaroxaban's therapeutic inhibition of factor Xa by 20% (104038).
|
Theoretically, St. John's wort might inhibit reuptake and increase levels of serotonin, resulting in additive effects with serotonergic drugs.
Details
|
St. John's wort decreases the levels and clinical effects of tacrolimus.
Details
Taking a St. John's wort extract (Jarsin) 600 mg daily significantly decreases tacrolimus serum levels. Dose increases of 60% may be required to maintain therapeutic tacrolimus levels in patients taking St. John's wort. St. John's wort is thought to lower tacrolimus levels by inducing cytochrome P450 3A4 (CYP3A4) enzymes (7095,10329).
|
St. John's wort might decrease the levels of theophylline, although this effect might not be clinically relevant.
Details
St. John's wort does not seem to significantly affect theophylline pharmacokinetics (11802). There is a single case report of a possible interaction with theophylline. A patient who smoked and was taking 11 other drugs experienced an increase in theophylline levels after discontinuation of St. John's wort. This increase has been attributed to a rebounding of theophylline serum levels after St. John's wort was no longer present to induce metabolism via cytochrome P450 1A2 (CYP1A2) (3556,7808,9204). However, studies in healthy volunteers show that St. John's wort is unlikely to affect theophylline to any clinically significant degree (11802).
|
St. John's wort might decrease the levels and clinical effects of tramadol.
Details
|
St. John's wort might decrease the levels and clinical effects of voriconazole.
Details
Clinical research shows that taking St. John's wort with voriconazole reduces voriconazole exposure and increases voriconazole metabolism by approximately 107%. Voriconazole is primarily metabolized by cytochrome P450 (CYP) 2C19, with CYP3A4 and CYP2C9 also involved (89660). St. John's wort induces CYP2C19, CYP3A4, and CYP2C9 (9204,10830,10847,10848,11889,11890,17405,22423,22424,22425)(22427,48603).
|
St. John's wort decreases the levels and clinical effects of warfarin.
Details
Taking St. John's wort significantly increases clearance of warfarin, including both its R- and S-isomers (11890,15176). This is likely due to induction of cytochrome P450 (CYP) 1A2 and CYP3A4 (11890). St. John's wort can also significantly decrease International Normalized Ratio (INR) in people taking warfarin (1292). In addition, taking warfarin at the same time as St. John's wort might reduce warfarin bioavailability. When a dried extract is mixed with warfarin in an aqueous medium, up to 30% of warfarin is bound to particles, reducing its absorption (10448).
|
St. John's wort might decrease the levels and clinical effects of zolpidem.

Below is general information about the adverse effects of the known ingredients contained in the product Trauma Drops. 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, arnica is unsafe and can cause toxicity.
When used in homeopathic amounts, arnica seem to be generally well tolerated. Topically, arnica also seems to be generally well tolerated.
Most Common Adverse Effects:
Orally: Bleeding, gastroenteritis, hypertension, muscle paralysis, nausea and vomiting, shortness of breath.
Topically: Contact dermatitis and irritation.
Serious Adverse Effects (Rare):
Orally: Arrhythmia, coma, multi-organ failure, and death.
Cardiovascular ...Orally, arnica can cause tachycardia or a faster heart rate (11,17113,19101,19102). A 24-year-old female presented to the emergency department with palpitations and vomiting 24 hours after ingesting a cup of tea that reportedly contained arnica flowers picked from her local area of mountainous Southern California. The species was not specified in the article and there was no indication by the authors that any testing had been done to confirm the identity of the plant (90610).
Dermatologic ...Orally, arnica can cause irritation of mucous membranes (11,17113). Topically, arnica can cause contact itchiness, dry skin, and rash (17113). Oral lesions resulted in a woman who used a mouthwash incorrectly by not following dilution instructions. The mouthwash was 70% alcohol and contained arnica and oil of peppermint (19106).
Gastrointestinal ...Orally, arnica can cause stomach pain, nausea, vomiting, and diarrhea (11,17113,19101,19102). Homeopathic arnica has been reported to cause dry mouth (30C) and sore tongue (6C) (19107). A 24-year-old female presented to the emergency department with palpitations and vomiting 24 hours after ingesting a cup of tea that reportedly contained arnica flowers picked from her local area of mountainous Southern California. The species was not specified in the article and there was no indication by the authors that any testing had been done to confirm the identity of the plant (90610).
Musculoskeletal ...Adverse effects after ingesting arnica include muscle weakness (19101). Homeopathic arnica has been reported to result in the feeling of a "throbby" head or neck (19107).
Neurologic/CNS ...Orally, arnica may cause drowsiness, nervousness, and headache (11,17113,19101,19107).
Ocular/Otic ...In a case report, accidental intake of a large amount of a homeopathic Arnica-30 resulted in acute vision loss due to bilateral toxic optic neuropathy (19105).
Psychiatric ...Oral homeopathic arnica (6C) may cause depressed feelings, specifically a feeling of unhappiness (19107).
Pulmonary/Respiratory ...Orally, arnica can cause shortness of breath (11,17113).
General
...Orally and topically, calendula is generally well tolerated.
Serious Adverse Effects (Rare):
All ROAs: Allergic reactions.
Dermatologic ...Topically, a preparation containing calendula powder 0. 1% resulted in inflammation around the wound to which it was applied (96647). Burning sensation, itching, redness, and scaling were reported rarely in patients applying a combination of calendula, licorice, and snail secretion filtrate to the face. The specific role of calendula is unclear (110322).
Immunologic ...Orally, calendula can cause allergic reactions. Topically, calendula can cause eczematous allergic reactions. Calendula-specific patch testing is recommended prior to usage to determine allergenic potential. Testing is particularly necessary in individuals sensitive to the Asteraceae/Compositae family (10691,11458,96647). Members of this family include ragweed, chrysanthemums, marigolds, daisies, and many other herbs. A preparation containing calendula powder 0.1% resulted in hives in a patient with a ragweed allergy (96647). Despite the widespread use of calendula and the occurrence of allergies to other family members, there has been only one report of anaphylaxis (11152).
General
...Orally, St.
John's wort is generally well tolerated.
Most Common Adverse Effects:
Orally: Diarrhea, dizziness, dry mouth, gastrointestinal discomfort (mild), fatigue, headache, insomnia, restlessness, and sedation.
Topically: Skin rash and photodermatitis.
Serious Adverse Effects (Rare):
Orally: There have been rare case reports of suicidal ideation and psychosis after taking St. John's wort.
Cardiovascular
...In clinical research, palpitations have been reported for patients taking St.
John's wort orally, although the number of these events was higher for the patients taking sertraline (76070). In one case report, an adult female developed recurrent palpitations and supraventricular tachycardia (SVT) within 3 weeks of initiating St. John's wort 300 mg daily. SVT and related symptoms responded to Valsalva maneuvers and did not recur after discontinuing therapy (106051).
Edema has also been reported in clinical research for some patients treated with St. John's wort 900-1500 mg daily for 8 weeks (10843). Cardiovascular collapse following induction of anesthesia has been reported in an otherwise healthy patient who had been taking St. John's wort for 6 months (8931). A case of St. John's wort-induced hypertension has been reported for a 56-year-old patient who used St. John's wort extract 250 mg twice daily for 5 weeks. Blood pressure normalized after discontinuation of treatment (76073). A case of new-onset orthostatic hypotension and light-headedness has been reported for a 70 year-old homebound patient who was taking multiple prescription medications and herbal products, including St. John's wort (76128). When all herbal products were discontinued, these symptoms improved, and the patient experienced improvement in pain control.
Dermatologic
...Both topical and chronic oral use of St.
John's wort can cause photodermatitis (206,620,758,4628,4631,6477,13156,17986,76072,76148)(95506,110318). The average threshold dose range for an increased risk of photosensitivity appears to be 1.8-4 grams St. John's wort extract or 5-10 mg hypericin, daily. Lower doses might not cause this effect (4542,7808). For example, a single dose of St. John's wort extract 1800 mg (5.4 mg hypericin) followed by 900 mg (2.7 mg hypericin) daily does not seem to produce skin hypericin concentrations thought to be high enough to cause phototoxicity (3900,4542,76266). Females appear to have a higher risk of dose-related photosensitivity. In a dose-ranging, small clinical trial, almost all of the female participants experienced mild to moderate photosensitivity with paresthesia in sun-exposed skin areas after administration of St. John's wort (Jarsin, Casella Med) 1800 mg daily for 3-6 days. Symptoms resolved about 12-16 days after discontinuation (95506). Male participants reported no adverse effects at this dose, and both genders reported no adverse effects at lower doses. Light or fair-skinned people should employ protective measures against direct sunlight when using St. John's wort either topically or orally (628).
Total body erythroderma without exposure to sunlight, accompanied by burning sensation of the skin, has also been reported (8930). Orally, St. John's wort may cause pruritus or skin rash, although these events seem to occur infrequently (76140,76148,76245). A case of persistent scalp and eyebrow hair loss has been reported for a 24-year-old schizophrenic female who was taking olanzapine plus St. John's wort 900 mg/day orally (7811). Also, a case of surgical site irritation has been reported for a patient who applied ointment containing St. John's wort (17225).
Endocrine ...A case of syndrome of inappropriate secretion of antidiuretic hormone (SIADH) in a 67-year-old male with depression has been reported. During a 3-month period, the patient was taking St. John's wort 300 mg daily then increased to 600-900 mg daily with no adverse effects despite a low serum sodium level of 122mEq/L, elevated levels of urine sodium, and urine osmolality suggestive of SIADH. St. John's wort appeared to be the only contributing factor. The patient's sodium level normalized 3 weeks after discontinuation of St. John's wort (95508).
Gastrointestinal ...Orally, St. John's wort may cause dyspepsia, anorexia, diarrhea, nausea, vomiting, and constipation, although these events seems to occur infrequently (4897,13021,17986,76070,76071,76113,76146,76150,76271).
Genitourinary
...Orally, St.
John's wort can cause intermenstrual or abnormal menstrual bleeding (1292,76056). However, this effect has occurred in patients who were also taking an oral contraceptive. Changes in menstrual bleeding might be the result of a drug interaction (1292,76056). Also, St. John's wort has been associated with anorgasmia and frequent urination when used orally (10843,76070).
Sexual dysfunction can occur with St. John's wort, but less frequently than with SSRIs (10843). A case of erectile dysfunction and orgasmic delay has been reported for a 49-year-old male after taking St. John's wort orally for one week. Co-administration of sildenafil 25-50 mg prior to sexual activity reversed the sexual dysfunction. Previously, the patient had experienced orgasmic delay, erectile dysfunction, and inhibited sexual desire when taking a selective serotonin reuptake inhibitor (sertraline) (4836).
Hepatic ...A case of acute hepatitis with prolonged cholestasis and features of vanishing bile duct syndrome has been reported for a patient who used tibolone and St. John's wort orally for 10 weeks (76135). A case of jaundice with transaminitis and hyperbilirubinemia has been reported for a 79 year-old female who used St. John's wort and copaiba (95505). Laboratory values normalized 7 weeks after discontinuation of both products.
Musculoskeletal ...Orally, St. John's wort may cause muscle or joint stiffness, tremor, muscle spasms, or pain, although these events appear to occur rarely (76070).
Neurologic/CNS ...St. John's wort may cause headache, dizziness, fatigue, lethargy, or insomnia (5096,13021,76070,76071,76113,76132,76133,76150,89666). Isolated cases of paresthesia have been reported for patients taking St. John's wort (5073). A case of subacute toxic neuropathy has been reported for a 35-year-old female who took St. John's wort 500 mg daily orally for 4 weeks (621).
Ocular/Otic ...There is concern that taking St. John's wort might increase the risk of cataracts. The hypericin constituent of St. John's wort is photoactive and, in the presence of light, may damage lens proteins, leading to cataracts (1296,17088). In population research, people with cataracts were significantly more likely to have used St. John's wort compared to people without cataracts (17088). Ear and labyrinth disorders have been possibly attributed to use of St. John's wort in clinical research, although these events rarely occur (76120).
Psychiatric
...St.
John's wort can induce hypomania in depressed patients and mania in depressed patients with occult bipolar disorder (325,3524,3555,3568,10845,76047,76064,76137,110318). Cases of first-episode psychosis have been reported for females who used St. John's wort orally. In both cases, symptoms resolved following discontinuation of St. John's wort and treatment with antipsychotics for several weeks (13015,89664). Also, psychosis and delirium have been reported for a 76-year-old female patient who used St. John's wort for 3 weeks. The patient may have been predisposed to this effect due to undiagnosed dementia (76270). Restlessness, insomnia, panic, and anxiety have been noted for some patients taking St. John's wort orally (5073,13156,76070,76132,76268,76269,89665).
In isolated cases, St. John's wort has been associated with a syndrome consisting of extreme anxiety, confusion, nausea, hypertension, and tachycardia. These symptoms may occur within 2-3 weeks after it is started, in patients with no other predisposing factors. This syndrome has been diagnosed as the serotonin syndrome (6201,7811,110318). In one case, the symptoms began after consuming tyramine-containing foods, including aged cheese and red wine (7812). In an isolated case, a 51-year-old female reported having had suicidal and homicidal thoughts for 9 months while taking vitamin C and a St. John's wort extract. Symptoms disappeared within 3 weeks of discontinuing treatment (76111). A case of decreased libido has been reported for a 42-year-old male with mood and anxiety disorders who had taken St. John's wort orally for 9 months (7312).
St. John's wort has been associated with withdrawal effects similar to those found with conventional antidepressants. Headache, nausea, anorexia, dry mouth, thirst, cold chills, weight loss, dizziness, insomnia, paresthesia, confusion, and fatigue have been reported. Withdrawal effects are most likely to occur within two days after discontinuation but can occur one week or more after stopping treatment in some people. Occurrence of withdrawal symptoms may not be related to dose or duration of use (3569,11801).
Pulmonary/Respiratory ...Orally, St. John's wort may cause sore throat, swollen glands, laryngitis, sinus ache, sweating, and hot flashes, although the frequency of these events appears to be similar to placebo (76150).
Renal ...Orally, St. John's wort has been associated with a case report of acute kidney failure in a 46-year-old female after one dose of homemade St. John's wort tea. Three sessions of hemodialysis were required before there was full recovery (106741). However, causality is unclear since the patient had also been taking diclofenac intermittently for a month prior to developing kidney failure.
Other ...Sjogren's syndrome has been reported in a patient taking herbal supplements including St. John's wort, echinacea, and kava. Echinacea may have been the primary cause, because Sjogren's syndrome is an autoimmune disorder. The role of St. John's wort in causing this syndrome is unclear (10319).
