Below is general information about the safety of the known ingredients contained in the product Terrific Zzzz. 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 topically in low concentrations, short-term. Concentrations ranging from 0.1% to 11% seem to be safe for short-term application to intact skin (272,10327,89893). ...when used by inhalation, appropriately. Even relatively dilute concentrations of camphor can irritate the nose and sinuses. However, it is difficult to determine a safe concentration of inhaled camphor. The Occupational Safety and Health Administration (OSHA) has set a permissible workplace air exposure to synthetic camphor of no more than 2 parts per million (ppm) (272,105033). It is unclear how this correlates to the exposure obtained from a camphor balm or steam bath.
LIKELY UNSAFE ...when used topically on broken or injured skin. Application of camphor to broken skin can result in systemic absorption and toxicity (272). ...when inhaled in large concentrations, which can result in systemic toxicity (13445,39666). However, it is difficult to determine a safe concentration of inhaled camphor. The National Institute for Occupational Safety and Health (NIOSH) has determined an Immediately Dangerous to Life or Health Concentration (IDLH) of synthetic camphor in workplace air to be 200 ppm (105033). It is unclear how this correlates to the exposure obtained from a camphor balm or steam bath.
UNSAFE ...when used orally. Although a particular oral product containing camphor and hawthorn (Korodin Herz-Kreislauf-Tropfen) has been used safely by adults in some clinical studies (103620), ingestion of camphor can cause significant toxicity, including death (13442). Oral preparations of camphor are no longer available in the US (13442).
CHILDREN: POSSIBLY UNSAFE
when used topically (4814).
Young children might be more susceptible to the adverse effects associated with even minor systemic absorption of camphor. The American Academy of Pediatrics recommends that camphor not be used in treating children (4814).
CHILDREN: UNSAFE
when used orally.
Ingestion of camphor can cause significant toxicity including death (4814). The American Academy of Pediatrics recommends that available non-prescription topical camphor products should not exceed 11% strength to limit toxicity if accidentally ingested by children (4814).
PREGNANCY AND LACTATION: UNSAFE
when used orally.
Ingestion of camphor can cause serious toxicity including death (13442). There is insufficient reliable information available about the safety of using camphor topically during pregnancy and lactation.
LIKELY SAFE ...when used orally in amounts commonly found in foods. Lavender has Generally Recognized as Safe (GRAS) status for food use in the US (4912).
POSSIBLY SAFE ...when used orally and appropriately in medicinal amounts (9792). In clinical research, a specific product containing lavender oil (Silexan, Dr Willmar Schwabe GmbH & Co. KG) has been used safely at doses of 80-160 mg daily for up to 10 weeks (58077,58080,58098,97257). Powdered dried lavender flowers 500 mg twice daily has also been used with apparent safety for up to 8 weeks (97256). ...when used topically and appropriately. Lavender oil has been used safely for up to 7 months in adults (5177,109858,109865). ...when the essential oil is inhaled as a part of aromatherapy. Clinical studies have used lavender oil aromatherapy with apparent safety for up to 12 weeks (7107,12213,16393,16394,95634,103062,103063,103065,103068).
CHILDREN: POSSIBLY SAFE
when the essential oil is inhaled as a part of aromatherapy.
Clinical studies have used lavender oil aromatherapy with apparent safety in single doses for up to 2 minutes (109868).
CHILDREN: POSSIBLY UNSAFE
when applied topically in males.
Anecdotal reports suggest that applying topical products containing lavender oil to prepubertal males may result in gynecomastia in some cases (15254,95643). Products with a higher concentration of lavender oil and more frequent applications might be more likely to result in gynecomastia.
PREGNANCY AND LACTATION:
Insufficient reliable evidence available.
Preliminary clinical research shows that lavender essential oil can be inhaled during labor, with no apparent adverse outcomes in the infants (95633). Although this study suggests safety, high quality assessment of safety has not been conducted.
LIKELY SAFE ...when used orally in amounts commonly found in foods. Lemon balm has Generally Recognized as Safe (GRAS) status in the US (4912).
POSSIBLY SAFE ...when used orally and appropriately, short-term. Lemon balm extract has been used with apparent safety at a dose of 500 mg daily for 6 months or at a dose of 3000 mg daily for 2 months (9993,9994,104435,104435,110136). ...when used topically and appropriately, short-term. Lemon balm 1% dried leaf extract has been used up to 4 times daily with apparent safety for a few days (790,9995).
CHILDREN: POSSIBLY SAFE
when used orally and appropriate, short-term.
A single dose of lemon balm extract 3-6 mg/kg has been safely used in children aged 6-7 years (19525). A specific combination product providing lemon balm leaf extract 80 mg and valerian root extract 160 mg (Euvegal forte, Dr. Willmar Schwabe Pharmaceuticals) 1-2 tablets once or twice daily has been safely used in children under 12 years of age for 30 days (14416). In infants up to 4 weeks old, multi-ingredient products (ColiMil, ColiMil Plus) containing lemon balm 64-97 mg daily have been used with apparent safety for up to 7 days (16735,96278).
PREGNANCY AND LACTATION:
Insufficient reliable information available; avoid using.
LIKELY SAFE ...when used orally in amounts commonly found in foods. Tangerine has Generally Recognized as Safe (GRAS) status in the US (4912). There is insufficient reliable information available about the safety of tangerine when used orally or topically as a medicine.
PREGNANCY AND LACTATION:
Insufficient reliable information available; avoid using.
Below is general information about the interactions of the known ingredients contained in the product Terrific Zzzz. 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 camphor with other hepatotoxic drugs might increase the risk of liver damage.

Theoretically, lavender might potentiate the therapeutic effects and adverse effects of CNS depressants.
Details
Laboratory research suggests that lavender has sedative effects (7). However, clinical studies in patients taking oral lavender oil (Silexan) 160 mg for 10 weeks or taking lavender flower powder 1 gram daily for 2 months have not reported side effects of drowsiness, sedation, or sleepiness (97256,103061). There is still some concern that higher doses or different preparations of lavender might have additive effects with CNS depressant medications.
|
Theoretically, concomitant use of lemon balm might have additive effects with CNS depressant drugs.
Details
|
Theoretically, lemon balm might interfere with thyroid hormone replacement therapy.
Details
In vitro, constituents of lemon balm extract bind to thyroid stimulating hormone (TSH), preventing TSH receptor-binding and leading to the inhibition of TSH-stimulated adenylate cyclase activity (19727,19728). In animals, lemon balm extract has been shown to decrease levels of circulating TSH and inhibit thyroid secretion (19726).

In vitro, tangeretin, a constituent of tangerine, induces a 52% increase in the metabolism of midazolam by cytochrome P450 3A4 (CYP3A4) (28609). This suggests that tangeretin may stimulate CYP3A4 activity. However, in humans, drinking tangerine juice 200 mL slightly delayed the absorption, but did not affect the metabolism, of midazolam, a CYP3A4 substrate (28609). Theoretically, tangerine juice might increase CYP3A4 activity and decrease levels of drugs metabolized by this enzyme. However, this effect is unlikely.
Details
Some drugs metabolized by CYP3A4 include amitriptyline (Elavil), amiodarone (Cordarone), citalopram (Celexa), felodipine (Plendil), lansoprazole (Prevacid), ondansetron (Zofran), prednisone (Deltasone, Orasone), sertraline (Zoloft), sibutramine (Meridia), and many others.

In vitro, tangeretin, a constituent of tangerine, appears to increase the metabolism of midazolam in human liver microsomes by up to 52% (28609). However, in humans, drinking tangerine juice 200 mL slightly delayed the absorption, but did not affect the metabolism, of midazolam (28609). Theoretically, tangerine juice might increase the metabolism and reduce the effects of midazolam. However, this effect is unlikely.

Below is general information about the adverse effects of the known ingredients contained in the product Terrific Zzzz. 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, camphor is unsafe and can cause significant toxicity.
Topically and by inhalation, camphor seems to be generally well-tolerated.
Most Common Adverse Effects:
Oral: Gastrointestinal and ocular symptoms of toxicity can occur within 5-90 minutes of ingestion. Neurological symptoms can occur with ingestion of quantities greater than 50 mg/kg.
Topically: Dermatitis and skin irritation.
Inhalation: Nose and sinus irritation.
Serious Adverse Effects (Rare):
All routes: Systemically absorbed camphor can lead to seizures, respiratory depression, coma, and death.
Cardiovascular ...Case reports of intoxication due to accidental or intentional consumption have included peripheral circulatory shock and sinus tachycardia (39649,97261). A 54-year-old female with a history of cardiomyopathy and atrial fibrillation developed several episodes of ventricular tachycardia and fibrillation requiring use of a defibrillator after ingestion of Vicks VapoRub, containing 4.8% camphor. She had been taking 7.5 grams of the product weekly, and took an additional 150 grams the week prior to admission. After discontinuing all camphor-containing products and receiving supportive measures, the patient's symptoms and laboratory abnormalities returned to normal (97260).
Dermatologic
...Orally, camphor can cause significant toxicity.
In more severe toxicity, general pallor and cyanosis of the lips occur (13442,13444). Topically, camphor is not as likely to cause adverse effects. But some amount of camphor can be absorbed through intact skin. Topical use of camphor has been associated with contact eczema (13445).
Warn patients not to heat products such as Vicks VapoRub in the microwave. Serious burns have occurred when the product is superheated in the microwave (13446).
Gastrointestinal ...Orally, camphor can cause significant toxicity. Symptoms of camphor toxicity occur rapidly within 5-90 minutes of ingestion. Burning of the mouth and throat, and nausea and vomiting are the first symptoms (13442,13444,39589,39626,39646,39658).
Hepatic ...Orally, camphor can cause transient elevations of liver enzymes in both adults and children. There is also a report of increased liver enzymes in an infant who received a camphor-containing topical cold remedy. The enzymes affected included aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase, and lactate dehydrogenase (LDH). The liver enzymes normalized after stopping the topical cold formula (4608).There is also a report of increased liver enzymes in a 35-year-old adult following "coining" with a balm containing camphor, which involves applying the balm and then rubbing the area with a coin until ecchymosis. The liver enzymes normalized after stopping treatment (39576). Elevated liver enzymes were also reported in a 54-year-old female after oral ingestion of Vicks VapoRub, containing 4.8% camphor. She had been taking 7.5 grams of the product weekly, and took an additional 150 grams the week prior to admission. After discontinuing all camphor-containing products and receiving supportive measures, the patient's symptoms and laboratory abnormalities returned to normal (97260).
Neurologic/CNS
...Orally, camphor can cause significant toxicity.
Neurological symptoms occur with ingestion of greater than 50 mg/kg. These symptoms include irritability, exaggerated tendon reflexes, tonic muscular contraction, myoclonic jerks, seizures, confusion, coma, and apnea. Seizures are sometimes the first manifestation of serious toxicity (13442,13444,39560,39589,39629,39646,39649,39658,39660). In children under 6 years of age, doses as low as 700-800 mg, and possibly as low as 500 mg, have caused serious seizures, resulting in respiratory failure and death (13442,13444,39589). Asymptomatic patients who have ingested camphor should be observed for at least 3 hours in a hospital. A 12-hour observation period may be prudent as seizures have occurred 9 hours after ingestion in apparently recovering patients. In patients who survive, symptoms usually resolve within 24 hours, although there are reports of persistent abnormalities for days to weeks. Long-term sequelae have not been reported after resolution of symptoms (13442,13443). In one case, a 10-year-old boy who intentionally ingested cold remedy transdermal patches containing a total of camphor 300 mg experienced mental status changes and tremulousness (39626).
Topically, camphor is not as likely to cause adverse effects, but small amounts can be absorbed through intact skin. A considerable amount of camphor can also be absorbed when inhaled. Excessive use of camphor, either topically or by inhalation, can result in the development of systemic toxicity (13445,39666). Topically and by inhalation, camphor has been associated with the occurrence of seizures. In one prospective observational study, there were 20 reports of new onset seizures and 29 reports of recurrent seizures in adults and children after use of camphor, either alone or in combination with eucalyptus oil. Most cases of seizure with topical use occurred 0.5-24 hours after topical application to the chest, neck, or face. Most cases of seizure with inhalation occurred about 2-30 minutes after steam inhalation of camphor (105028).
Ocular/Otic
...Orally, camphor can cause significant toxicity.
Ocular symptoms such as mydriasis and darkening of vision may occur (13442,13444). There is a case report of blurry vision following accidental ingestion of camphor (39667).
There is a case report of self-inflicted conjunctival inflammation after using camphor in the eyes (39624). Warn patients not to heat products such as Vicks VapoRub in the microwave. Eye injury has occurred when the product is superheated in the microwave (13446).
Pulmonary/Respiratory
...When inhaled in large enough concentrations, camphor can irritate the nose and sinuses.
However, it is difficult to determine a safe concentration of inhaled camphor (105033).
A 54-year-old females with a history of asthma developed shortness of breath, hypoxemia, and respiratory acidosis after oral ingestion of Vicks VapoRub, containing 4.8% camphor. She had been taking 7.5 grams of the product weekly, and took an additional 150 grams the week prior to admission. After discontinuing all camphor-containing products and receiving supportive measures, the patient's symptoms and laboratory abnormalities returned to normal (97260).
Other ...A smell of camphor from the breath and body have been reported following oral intake of camphor (39560,39589,97261).
General
...Orally, lavender is well tolerated in food amounts and seems to be well tolerated in larger amounts.
Topically, lavender oil seems to be well tolerated.
Most Common Adverse Effects:
Orally: Breath odor, constipation, diarrhea, dyspepsia, eructation, headache, and nausea.
Topically: Allergic contact dermatitis (with lavender oil).
Serious Adverse Effects (Rare):
Topically: Cases of gynecomastia have been reported in prepubertal males using lavender oil.
Cardiovascular ...Orally, a specific lavender oil ingredient (Silexan) has been associated with palpitations (103061).
Endocrine ...Topical products containing lavender oil alone, including a product referred to as agua de violetas, or in combination with tea tree oil have been linked to at least six cases of gynecomastia when used in prepubertal males. In each case, gynecomastia resolved when the lavender oil products were discontinued. It is thought that the estrogenic and antiandrogenic activity of lavender oil and tea tree oil resulted in gynecomastia in these cases (15254,95643).
Gastrointestinal ...Orally, lavender oil, including a specific lavender oil ingredient KG), may cause gastrointestinal disturbance, including dyspepsia, diarrhea, breath odor, eructation, and nausea (58077,58080,58098,93004,103061). Tincture of lavender has been linked to cases of constipation and increased appetite; however, it is unknown if this occurred at a greater rate than with placebo (9792).
Immunologic ...Topically, use of lavender oil, such as in personal care products, might cause allergic contact dermatitis in some patients (6,101728). There have been numerous case reports of allergic contact dermatitis and eczema linked to lavender oil exposure from shampoos, lotions, fragrances, or direct application of oil to pillows (10031,58043,58109,58120,101728).
Neurologic/CNS ...Orally, lavender flower powder, tincture of lavender containing 50% alcohol, and a specific lavender oil ingredient (Silexan) have been linked to headache (9792,103061,109860). Headache has also been reported rarely following lavender oil aromatherapy (109860).
Pulmonary/Respiratory ...In one case report, a 34-year-old Japanese female presented with complaints of dyspnea, cough, and fever 2 weeks after initiating lavender essential oil therapy via humidifier. The patient had an oxygen saturation of 88% and was diagnosed with acute eosinophilic pneumonia. Symptoms improved after a course of corticosteroids and discontinuation of aromatherapy (109979).
General
...Orally, lemon balm seems to be well tolerated in food amounts and larger, medicinal amounts.
Topically, lemon balm seems to be well tolerated.
Serious Adverse Effects (Rare):
Orally: Wheezing has been rarely reported.
Cardiovascular ...Orally, a case of transient complete atrioventricular block and QT prolongation is reported in a 25-year-old female following the post-workout use of a specific product (Muscle Eze Advanced) containing lemon balm and several other ingredients. Symptoms of fatigue and lightheadedness started 1 week into use of the product. Product discontinuation led to restoration of normal sinus rhythm within 24 hours and normalization of the electrocardiogram within 2 weeks (112556). It is unclear whether this occurrence is due to lemon balm, other ingredients, or the combination.
Dermatologic ...Topically, lemon balm 1% cream applied 5 times daily to cold sores has been associated with two cases of irritation and one case of cold sore exacerbation. However, these effects do not appear to occur more often with lemon balm than with placebo (790).
Gastrointestinal ...Orally, lemon balm might increase appetite in some patients (91732,104433). Nausea, vomiting, and abdominal pain have been reported rarely and do not seem to occur more often than in patients taking placebo (9993).
Neurologic/CNS ...Orally, lemon balm has been reported to cause dizziness and sedation; however, it does not seem to occur more often with lemon balm than placebo (9993,104433). Additionally, other clinical research shows that using lemon balm in conjunction with alcohol does not affect reaction time or influence cognitive performance (19427,19723).
Pulmonary/Respiratory ...Orally, lemon balm has been associated with rare cases of wheezing (9993).
General
...Orally, very few adverse effects have been reported with the medicinal use of tangerine.
However, a thorough evaluation of safety outcomes has not been conducted.
Topically, contact dermatitis has been associated with tangerine essential oil (28610).
Dermatologic ...According to one case report, the essential oil of tangerine in a fragrance has been associated with contact dermatitis (28610).
Gastrointestinal ...In a case report, a 5 year-old patient had a phytobezoar that included tangerine residues (28611). In another case report, orange and tangerine caused obstruction of the small intestine (28612).
