Below is general information about the safety of the known ingredients contained in the product VRM4 Cellular Pathogens. 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 consumed in amounts typically found in foods. Guarana has Generally Recognized as Safe (GRAS) status for use in foods in the US (4912).
POSSIBLY SAFE ...when used orally and appropriately, short-term (12). Guarana contains caffeine. According to a review by Health Canada, and a subsequent large meta-analysis conducted in the US, doses of caffeine up to 400 mg daily are not associated with significant adverse cardiovascular, bone, behavioral, or reproductive effects in healthy adults (11733,98806). The US Dietary Guidelines Advisory Committee states that there is strong and consistent evidence that consumption of caffeine 400 mg daily is not associated with increased risk of major chronic diseases, such as cardiovascular disease or cancer, in healthy adults (98806).
POSSIBLY UNSAFE ...when used orally long-term or in high doses. Guarana contains a significant amount of caffeine. Chronic use, especially in large amounts, can produce tolerance, habituation, psychological dependence, and other significant adverse effects. Acute use of high doses, typically above 400 mg per day, has been associated with significant adverse effects such as tachyarrhythmias and sleep disturbances (11832,95503,98806). These effects would not be expected to occur with the consumption of decaffeinated guarana.
LIKELY UNSAFE ...when used orally in very high doses. The fatal acute oral dose of caffeine is estimated to be 10-14 grams (150-200 mg per kilogram). Serious toxicity can occur at lower doses depending on variables in caffeine sensitivity such as smoking, age, or prior caffeine use (11832,54425).
PREGNANCY: POSSIBLY SAFE
when consumed in amounts commonly found in foods.
Due to the caffeine content of guarana, intake should be closely monitored during pregnancy to ensure moderate consumption. Although it is not considered a teratogen, caffeine crosses the placenta and causes dose-dependent increases in fetal blood concentrations (4260). The use of caffeine during pregnancy is controversial; however, moderate consumption has not been associated with clinically important adverse fetal effects (2708,2709,2710,2711,9606,11733,16014,16015,98806). In some studies, consuming amounts over 200 mg daily is associated with a significantly increased risk of miscarriage (16014). This increased risk may be most likely to occur in individuals with genotypes that confer a slow rate of caffeine metabolism (98806). According to a review by Health Canada, and a subsequent large meta-analysis conducted in the US, caffeine can be safely consumed in doses up to 300 mg daily without an increased risk of spontaneous abortion, stillbirth, preterm birth, fetal growth retardation, or congenital malformations (11733,98806). However, some research has also found that intrauterine exposure to even modest amounts of caffeine, based on maternal blood levels during the first trimester, is associated with a shorter stature in children ages 4-8 years (109846). Advise individuals to keep caffeine consumption below 300 mg daily during pregnancy.
PREGNANCY: POSSIBLY UNSAFE
when used orally in amounts over 300 mg daily.
Although it is not considered a teratogen, caffeine crosses the placenta and causes dose-dependent increases in fetal blood concentrations (4260,98806). Consumption of caffeine in amounts over 300 mg daily is associated with a significantly increased risk of miscarriage in some studies (16014,98806). Advise keeping caffeine consumption from all sources below 300 mg daily. High maternal doses of caffeine throughout pregnancy have resulted in symptoms of caffeine withdrawal in newborn infants (9891). High doses of caffeine have also been associated with spontaneous abortion, premature delivery, and low birth weight (2709,2711).
LACTATION: POSSIBLY SAFE
when used orally in amounts commonly found in foods.
Due to the caffeine content of guarana, intake should be closely monitored when breast-feeding. Breast milk concentrations of caffeine are thought to be approximately 50% of serum concentrations (9892).
LACTATION: POSSIBLY UNSAFE
when used orally in large amounts.
Consumption of guarana might cause irritability and increased bowel activity in nursing infants (6026). Large doses or excessive intake of guarana should be avoided when breast-feeding.
There is insufficient reliable information available about the safety of kamala.
PREGNANCY AND LACTATION:
Insufficient reliable information available; avoid using.
LIKELY SAFE ...when used orally in amounts commonly found in foods. Papain has Generally Recognized as Safe (GRAS) status in the US (4912).
POSSIBLY SAFE ...when used orally and appropriately for medicinal purposes, short-term. Papain has been used in combination with other proteolytic enzymes at a dose of up to 1200 mg daily for up to 9 weeks (964,965,968,67831,67834). ...when used topically as a diluted solution in appropriate doses for up to 20 minutes (67835,67843,67845).
POSSIBLY UNSAFE ...when used orally in large amounts. In excessive doses, papain can cause significant side effects including esophageal perforation (6). ...when raw papain is used topically. Raw papain or papaya latex is a severe irritant and vesicant (6).
PREGNANCY: POSSIBLY UNSAFE
when used orally.
There is some concern that crude papain is teratogenic and embryotoxic (6).
LACTATION:
Insufficient reliable information available; avoid using.
LIKELY SAFE ...when used orally as a flavoring in foods. The US Food and Drug Administration (FDA) lists passion flower as a permitted food flavoring additive, to be used in the minimum quantity necessary (91203).
POSSIBLY SAFE ...when used orally and appropriately in medicinal amounts, short-term. Passion flower extract has been used with apparent safety at doses up to 800 mg daily for up to 8 weeks (88198,102866). A specific passion flower extract (Pasipay, Iran Darouk Pharmaceutical Company) has been safely used at a dose of 45 drops daily for up to one month (8007,95036). Also, a tea prepared by steeping 2 grams of the dried aerial parts of passion flower in 250 mL of boiling water for 10 minutes has been used nightly for 7 nights (17374). There is insufficient reliable information available about the safety of passion flower when used topically.
CHILDREN: POSSIBLY SAFE
when used orally and appropriately, short-term.
A specific passion flower product (Pasipay, Iran Darouk Pharmaceutical Company) has been used safely in children aged 6-13 years at a dose of 0.04 mg/ kg daily for 8 weeks (88197).
PREGNANCY: POSSIBLY UNSAFE
when used orally.
Some case reports suggest that passion flower use during the first and second trimesters of pregnancy may be associated with an increased risk for premature rupture of membranes and meconium aspiration syndrome; however, causality has not been confirmed (97279). The alkaloids harman and harmaline, which are sometimes found in passion flower, have been reported to have uterine stimulant activity (4,11020,95037). It is not known whether these constituents are present in sufficient quantities to have an effect.

Below is general information about the interactions of the known ingredients contained in the product VRM4 Cellular Pathogens. 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, concomitant use of chenopodium oil with other photosensitizing drugs can increase the risk of adverse effects.
Details
Chenopodium species are also associated with photosensitivity (19).
|
Theoretically, guarana might decrease the vasodilatory effects of adenosine and interfere with its use prior to stress testing.
Details
Guarana contains caffeine. Caffeine is a competitive inhibitor of adenosine at the cellular level. However, caffeine does not seem to affect supplemental adenosine because high interstitial levels of adenosine overcome the antagonistic effects of caffeine (11771). It is recommended that methylxanthines and methylxanthine-containing products be stopped 24 hours prior to pharmacological stress tests (11770). However, methylxanthines appear more likely to interfere with dipyridamole (Persantine) than adenosine-induced stress testing (11771).
|
Theoretically, alcohol might increase the levels and adverse effects of caffeine.
Details
Guarana contains caffeine. Concomitant use of alcohol can increase caffeine serum concentrations and the risk of caffeine adverse effects. Alcohol reduces caffeine metabolism (6370).
|
Theoretically, guarana may increase the risk of bleeding if used with anticoagulant or antiplatelet drugs.
Details
|
Theoretically, taking guarana with antidiabetes drugs might interfere with blood glucose control.
Details

Details
Guarana contains caffeine. Theoretically, concomitant use of large amounts of caffeine might increase cardiac inotropic effects of beta-agonists (15).
|
Theoretically, guarana might reduce the effects of carbamazepine and increase the risk for convulsions.
Details
Animal research suggests that taking caffeine can lower the anticonvulsant effects of carbamazepine and can induce seizures when given to animals in doses above 400 mg/kg (23559,23561). Human research has shown that taking caffeine 300 mg in three divided doses along with carbamazepine 200 mg reduces the bioavailability of carbamazepine by 32% and prolongs the plasma half-life of carbamazepine two-fold in healthy individuals (23562).
|
Theoretically, concomitant use might increase the effects and adverse effects of caffeine in guarana.
Details
Guarana contains caffeine. Cimetidine decreases the rate of caffeine clearance by 31% to 42% (11736).
|
Theoretically, guarana might increase the levels and adverse effects of clozapine and acutely exacerbate psychotic symptoms.
Details
Guarana contains caffeine. Caffeine can increase the effects and toxicity of clozapine. Caffeine doses of 400-1000 mg per day inhibit clozapine metabolism (5051). Clozapine is metabolized by cytochrome P450 1A2 (CYP1A2). Researchers speculate that caffeine might inhibit CYP1A2. However, there is no reliable evidence that caffeine affects CYP1A2. There is also speculation that genetic factors might make some patients more sensitive to the interaction between clozapine and caffeine (13741).
|
Theoretically, concomitant use might increase the effects and adverse effects of caffeine found in guarana.
Details
|
Theoretically, concomitant use might increase the levels and adverse effects of caffeine.
Details
|
Theoretically, guarana might decrease the vasodilatory effects of dipyridamole and interfere with its use prior to stress testing.
Details
Guarana contains caffeine. Caffeine might inhibit dipyridamole-induced vasodilation (11770,11772). It is recommended that methylxanthines and methylxanthine-containing products be stopped 24 hours prior to pharmacological stress tests (11770). Methylxanthines appear more likely to interfere with dipyridamole than adenosine-induced stress testing (11771).
|
Theoretically, disulfiram might increase the risk of adverse effects from caffeine.
Details
In human research, disulfiram decreases the clearance and increases the half-life of caffeine (11840).
|
Theoretically, using guarana with diuretic drugs might increase the risk of hypokalemia.
Details
|
Theoretically, concomitant use might increase the risk for stimulant adverse effects.
Details
Guarana contains caffeine. Use of ephedrine with caffeine can increase the risk of stimulatory adverse effects. There is evidence that using ephedrine with caffeine might increase the risk of serious life-threatening or debilitating adverse effects such as hypertension, myocardial infarction, stroke, seizures, and death (1275,6486,10307).
|
Theoretically, estrogens might increase the levels and adverse effects of caffeine.
Details

|
Theoretically, fluvoxamine might increase the levels and adverse effects of caffeine.
Details
Guarana contains caffeine. Fluvoxamine reduces caffeine metabolism (6370).
|
Theoretically, abrupt guarana withdrawal might increase the levels and adverse effects of lithium.
Details
|
Theoretically, metformin might increase the levels and adverse effects of caffeine.
Details

|
Theoretically, mexiletine might increase the levels and adverse effects of caffeine.
Details
|
Theoretically, concomitant use might increase the risk of a hypertensive crisis.
Details
Guarana contains caffeine. Caffeine has been shown to inhibit MAO-A and -B in laboratory studies (37724,37877,37912,38108). Concomitant intake of large amounts of caffeine with MAOIs might precipitate a hypertensive crisis (15). In a case report, a patient that consumed 10-12 cups of caffeinated coffee and took the MAOI tranylcypromine presented with severe hypertension (91086). Hypertension was resolved after the patient switched to drinking decaffeinated coffee.
|
Theoretically, concomitant use might increase the risk of hypertension.
Details
Guarana contains caffeine. Concomitant use of caffeine and nicotine has been shown to have additive cardiovascular effects, including increased heart rate and blood pressure. Blood pressure was increased by 10.8/12.4 mmHg when the agents were used concomitantly (36549).
|
Theoretically, guarana might decrease the effects of pentobarbital.
Details
|
Theoretically, guarana might reduce the effects of phenobarbital and increase the risk for convulsions.
Details
|
Theoretically, phenothiazines might increase the levels and adverse effects of caffeine.
Details
|
Theoretically, phenylpropanolamine might increase the risk of hypertension, as well as the levels and adverse effects of caffeine.
Details
|
Theoretically, guarana might reduce the effects of phenytoin and increase the risk for convulsions.
Details
|
Theoretically, guarana might increase the levels and clinical effects of pioglitazone.
Details
Guarana contains caffeine. Animal research suggests that caffeine can modestly increase the maximum concentration, area under the curve, and half-life of pioglitazone, and also reduce its clearance. This increased the antidiabetic effects of pioglitazone (108812). However, the exact mechanism of this interaction is unclear.
|
Theoretically, quinolone antibiotics might increase the levels and adverse effects of caffeine.
Details
|
Theoretically, concomitant use might increase the levels and adverse effects of both caffeine and riluzole.
Details
Guarana contains caffeine. Caffeine and riluzole are both metabolized by cytochrome P450 1A2 (CYP1A2), and concomitant use might reduce the metabolism of one or both agents (11739).
|
Theoretically, concomitant use might increase stimulant adverse effects.
Details
Guarana contains caffeine. Due to the central nervous system (CNS) stimulant effects of caffeine, concomitant use with stimulant drugs can increase the risk of adverse effects (11832).
|
Theoretically, terbinafine might increase the levels and adverse effects of caffeine.
Details
Guarana contains caffeine. Terbinafine decreases the clearance of intravenous caffeine by 19% (11740).
|
Theoretically, guarana might increase the levels and adverse effects of theophylline.
Details
Guarana contains caffeine. Large amounts of caffeine might decrease theophylline clearance by 23% to 29% (11741).
|
Theoretically, guarana might increase the levels and adverse effects of tiagabine.
Details
Guarana contains caffeine. Animal research shows that chronic caffeine administration can increase the serum concentrations of tiagabine. However, concomitant use does not seem to reduce the antiepileptic effects of tiagabine (23561).
|
Theoretically, ticlopidine might increase the levels and adverse effects of caffeine.
Details
Guarana contains caffeine. In vitro evidence shows that ticlopidine can inhibit the metabolism of caffeine (23557). However, this interaction has not been reported in humans.
|

Details
|
Theoretically, verapamil might increase the levels and adverse effects of caffeine.
Details
Verapamil increases plasma caffeine concentrations by 25% (11741).
|
Theoretically, papain might increase the effects and side effects of warfarin.
Details
In one case report, a patient previously stable on warfarin was found to have an international normalization ratio (INR) of 7.4, which was attributed to ingestion of a supplement containing papain from papaya extract (613).
|
Concomitant use of passion flower with sedative drugs might cause additive effects and side effects.
Details
|
Theoretically, passion flower might decrease the effects of CYP3A4 substrates.
Details
In vitro research suggests that passion flower can induce CYP3A4 enzymes, albeit to a much lower degree than rifampin, a known CYP3A4 inducer (110704).
|
Theoretically, passion flower might reduce the bioavailability of OATP2B1 and OATP1A2 substrates.
Details
In vitro research shows that the passion flower constituents apigenin and vitexin inhibit OATP2B1 and OATP1A2. This inhibition may be dose-dependent. One specific high-flavonoid passion flower extract (Valverde) seems to inhibit OATP2B1 and OATP1A2, while another extract with a lower flavonoid concentration (Arkocaps) shows less potent inhibition (105095). OATPs are responsible for the uptake of drugs and other compounds into the body; however, the specific activities of OATP2B1 and OATP1A2 are not well characterized.

Below is general information about the adverse effects of the known ingredients contained in the product VRM4 Cellular Pathogens. 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, chenopodium oil is unsafe.
Most Common Adverse Effects:
Orally: Dizziness, headache, mucous membrane irritation, skin irritation, vertigo, vomiting.
Serious Adverse Effects (Rare):
Orally: Circulatory collapse, convulsions, deafness, death, kidney and liver damage, paralysis.
Dermatologic ...Orally, chenopodium oil can cause skin and mucous membrane irritation (11).
Gastrointestinal ...Orally, chenopodium oil can cause vomiting (11).
Hepatic ...Orally, chenopodium oil can cause liver damage (11).
Neurologic/CNS ...Orally, chenopodium oil affects the nervous system and can cause headache, vertigo/dizziness, temporary deafness, convulsions, circulatory collapse, paralysis, and death (11).
Renal ...Orally, chenopodium oil can cause kidney damage (11).
General
...Orally, guarana is typically well tolerated when used in moderation.
Due to its caffeine content, use of large doses may be unsafe.
Most Common Adverse Effects:
Orally: Stomach burning and nausea.
Cardiovascular
...Orally, a case of premature ventricular contraction has been reported for a 51-year-old female who used guarana as part of a multi-ingredient herbal product (54372).
Guarana contains caffeine. Although acute administration of caffeine can increase blood pressure, regular consumption does not seem to increase either blood pressure or pulse, even in mildly hypertensive patients (1451,1452,2722). Also, epidemiological research suggests there is no association between caffeine consumption and increased incidence of hypertension. Habitual coffee consumption doesn't seem to be related to hypertension, but habitual consumption of sugared or diet cola is associated with development of hypertension (13739).
Combining ephedra with guarana can increase the risk of adverse effects. Cases of hypertension and chest pain have been reported for patients who took products containing guarana and ephedra (8644,54376). A case of cerebral infarction has also been reported for a patient consuming ephedra extract and guarana (48746). There is also a report of ischemic stroke in an athlete who consumed ephedra 40-60 mg, creatine monohydrate 6 grams, caffeine 400-600 mg, and a variety of other supplements daily for six weeks (1275).
Dermatologic ...Guarana contains caffeine. There are several case reports of urticaria after caffeine ingestion (36546,36448,36475).
Endocrine
...Guarana contains caffeine.
Some evidence shows caffeine is associated with fibrocystic breast disease, breast cancer, and endometriosis; however, this is controversial since findings are conflicting (8043). Restricting caffeine in people with fibrocystic breast conditions doesn't seem to affect breast nodularity, swelling, or pain (8996). A population analysis of the Women's Health Initiative observational study has found no association between consumption of caffeine-containing beverages and the incidence of invasive breast cancer in models adjusted for demographic, lifestyle, and reproductive factors (108806). Also, a dose-response analysis of 2 low-quality observational studies has found that high consumption of caffeine is not associated with an increased risk of breast cancer (108807).
Although the effects of guarana alone are not clear, the combination of guarana along with ephedra has been reported to cause increased blood glucose levels and decreased blood levels of potassium (54376).
Gastrointestinal ...Orally, guarana can cause a sensation of burning in the stomach and vomiting (54414,91487). These effects may be due to caffeine in guarana. Orally, caffeine can cause gastric irritation, nausea, and vomiting (11832,11838,13735). In infants, caffeine may also cause feeding intolerance and gastrointestinal irritation (6023).
Immunologic ...Guarana contains caffeine. When taken orally, caffeine can cause anaphylaxis in sensitive individuals, although true IgE-mediated caffeine allergy seems to be relatively rare (11315).
Musculoskeletal
...In a clinical trial of guarana extract, one person abandoned treatment due to symptoms of arthritis with edema.
It is not clear if this adverse effect is due to guarana (91487).
Cases of rhabdomyolysis and myoglobinuria have been reported in individuals that have taken products containing guarana in combination with ephedra and other herbal products. These adverse effects are thought to be related to the caffeine content of guarana (19154,36466).
Epidemiological evidence regarding the relationship between caffeine use and the risk for osteoporosis is contradictory. Caffeine can increase urinary excretion of calcium (2669,10202,11317). Women identified with a genetic variant of the vitamin D receptor appear to be at an increased risk for the detrimental effect of caffeine on bone mass (2669). However, moderate caffeine intake, less than 300 mg per day, does not seem to significantly increase osteoporosis risk in most postmenopausal women with normal calcium intake (2669,6025,10202,11317).
Neurologic/CNS
...Orally, guarana can cause dizziness (91483).
The caffeine in guarana can cause insomnia (especially in children), nervousness, restlessness, dizziness, tremors, delirium, and convulsions. Other symptoms include headache, anxiety, and agitation (10755,11832,11838,13735,108016).
Taking guarana with ephedra can cause insomnia, irritability, dizziness, and headache (3719). The combination of ephedra and caffeine in guarana might also increase the risk of adverse effects such as jitteriness, seizures, and temporary loss of consciousness (2729,21015).
Ocular/Otic ...Guarana contains caffeine. When taken orally, caffeine can cause ringing in the ears (11832,11838,13735).
Psychiatric ...In a clinical trial, depression was reported by one person taking guarana extract (91483).
Renal ...Guarana contains caffeine. When taken orally, caffeine can cause diuresis (11832,11838,13735).
Other ...Guarana contains caffeine. The existence or clinical importance of caffeine withdrawal is controversial. Some researchers think that if it exists, it appears to be of little clinical significance (11839). Other researchers suggest symptoms such as headache; tiredness and fatigue; decreased energy, alertness, and attentiveness; drowsiness; decreased contentedness; depressed mood; difficulty concentrating; irritability; and lack of clear-headedness are typical of caffeine withdrawal (13738). Withdrawal symptoms such as delirium, nausea, vomiting, rhinorrhea, nervousness, restlessness, anxiety, muscle tension, muscle pains, and flushed face have been described. However, these symptoms may be from nonpharmacological factors related to knowledge and expectation of effects. Clinically significant symptoms caused by caffeine withdrawal may be uncommon (2723,11839).
General ...None reported; however, a thorough evaluation of safety outcomes has not been conducted.
General
...Orally and topically, papain seems to be well tolerated when used short-term at appropriate doses.
Taking high oral doses may be unsafe.
Most Common Adverse Effects:
Orally: Allergic reactions in sensitive individuals.
Topically: Urticaria and pruritus in sensitive individuals.
Serious Adverse Effects (Rare):
Orally: Esophageal perforation and severe gastritis with high doses.
Dermatologic ...Topically, papain can cause itching (966). Urticarial reactions and itching have been reported in people occupationally exposed to papain, with papain confirmed as the causative agent by skin prick tests or radioallergosorbent tests (RAST) (95533,95534). In a randomized controlled trial assessing the effects of papain, trypsin, and chymotrypsin on adverse effects from radiotherapy, moderate to severe epitheliolysis was more frequent in the enzyme-treated group than the placebo group (67834). It is unclear if this adverse effect is due to papain, other enzymes, or the combination.
Gastrointestinal ...Orally, papain has been associated with diarrhea. In a randomized controlled trial assessing the effects of papain, trypsin, and chymotrypsin on adverse effects from radiotherapy, moderate to severe diarrhea was more frequent in the enzyme-treated group than the placebo group (67834). However, it is unclear if this adverse effect is due to papain, other enzymes, or the combination. Papain has also been associated with gastric ulcers and esophageal perforation in case reports of phytobezoars treated with papain (67848). In general, large amounts of papain can cause esophageal perforation (6). Ingestion of papaya latex (raw papain) can cause severe gastritis.
Genitourinary ...Orally, papain has been associated with hypernatremia in case reports of phytobezoars treated with papain (67848).
Immunologic ...Orally, papain may cause allergic reactions, including itchy watery eyes, runny nose, sneezing, abdominal cramps, sweating, and diarrhea, in individuals sensitive to papain (6,967). Occupational exposure to airborne papain dust may also cause respiratory allergic reactions (95532,95533,95534,95535,95536).
Pulmonary/Respiratory ...Occupational exposure to airborne papain dust may cause respiratory allergic reactions. Symptoms include rhinitis, sneezing, conjunctivitis, dyspnea, wheezing, cough, and asthma. In most cases, papain is confirmed as the causative agent by skin prick tests, radioallergosorbent tests (RAST), or detection of papain-specific immunoglobulin E (IgE) and IgG (95532,95533,95534,95535,95536).
General
...Orally, passion flower is well tolerated.
Most Common Adverse Effects:
Orally: Confusion, dizziness, hypersensitivity, and sedation.
Cardiovascular ...There is a case report involving a 34-year-old female who was hospitalized with severe nausea, vomiting, drowsiness, prolonged QT interval, and episodes of nonsustained ventricular tachycardia following use of passion flower extract tablets (Sedacalm, Bioplus Healthcare), 1500 mg on day 1 and 2000 mg on day 2 to relieve stress. All symptoms resolved within one week after passion flower was discontinued (6251).
Genitourinary ...The alkaloids harman and harmaline, which are sometimes found in small amounts in passion flower, have been reported to have uterine stimulant activity (4,11020,95037).
Hematologic ...Orally, passion flower has been reported to cause epistaxis in one clinical trial (95038). Vasculitis has also been reported with use of a specific herbal product (Relaxir) produced mainly from the fruits of passion flower (6).
Hepatic ...There is debate about whether passion flower contains cyanogenic glycosides. Several related Passiflora species do contain these constituents (3), including Passiflora edulis, which is associated with liver and pancreatic toxicity (7).
Immunologic
...An idiosyncratic hypersensitivity reaction characterized by urticaria and cutaneous vasculitis has been reported in a 77-year-old male with rheumatoid arthritis after taking a specific combination product that included passion flower extract (Naturest) (68308).
It is unclear if these effects were caused by passion flower or other ingredients.
In clinical trials, passion flower has been reported to cause allergy symptoms including sinus irritation; however, the frequency of these events was statistically nonsignificant when compared to treatment with midazolam 15 mg (95038).
Musculoskeletal ...Orally, passion flower has been reported to cause muscle relaxation in a clinical trial (95038).
Neurologic/CNS ...Orally, sedation, dizziness, ataxia, and confusion have been reported in clinical trials. However, these events generally do not necessitate discontinuation (8007,15391,15392,95036,95038). Altered consciousness has been reported with use of a specific herbal product (Relaxir) produced mainly from the fruits of passion flower (6).
General
...Orally, wormseed is unsafe.
Serious Adverse Effects (Rare):
Symptoms of poisoning are possible in the amounts traditionally used as medicine. Symptoms of toxicity include epileptiform spasms, gastroenteritis, kidney irritation, muscle twitching, stupor, visual disorders, and even death.
Gastrointestinal ...Orally, wormseed can cause gastroenteritis (18).
Immunologic ...Orally, wormseed can cause allergic reactions in individuals sensitive to the Asteraceae/Compositae family, which includes ragweed, chrysanthemums, marigolds, daisies, and many other herbs (18).
Musculoskeletal ...Orally, wormseed can cause muscle twitching (18).
Neurologic/CNS ...Orally, wormseed can cause epileptiform spasms (18).
Ocular/Otic ...Orally, wormseed can cause visual disorders (18).
Renal ...Orally, wormseed can cause kidney irritation (18).
Other ...Orally, death has been reported with less than 10 grams of wormseed (18).
