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 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.

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.
LACTATION:

Below is general information about the interactions of the known ingredients contained in the product Stress Support 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.
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).
|
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.
|
Theanine might lower blood pressure, potentiating the effects of antihypertensive drugs.
Details
|
Theoretically, theanine might have additive sedative effects when used in conjunction with CNS depressants. However, it is unclear if this concern is clinically relevant.

Below is general information about the adverse effects of the known ingredients contained in the product Stress Support 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, 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, 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, L-theanine seems to be well tolerated.
Most Common Adverse Effects:
Orally: Drowsiness, headaches.
Neurologic/CNS
...Orally, L-theanine may cause headaches (36439).
Patients have also reported drowsiness, increased duration of sleep, and increased dream activity after oral L-theanine use (96331).
A case of subtle facial tic starting within 4 days of taking L-theanine 400 mg daily has been reported for a pediatric patient. Although the tics reportedly ceased once theanine was discontinued, the child had exhibited tics in the past. Therefore, the adverse effect was not thought to be related to L-theanine (91744).
