Below is general information about the safety of the known ingredients contained in the product Thuja Ointment. Some ingredients may not be listed. This information does NOT represent a recommendation for or a test of this specific product as a whole.
LIKELY SAFE ...when used orally in amounts commonly found in foods. Thuja that is thujone-free has Generally Recognized As Safe (GRAS) status for use in foods in the US (4912).
POSSIBLY UNSAFE ...when used orally in medicinal amounts. Large doses of thuja have been reported to cause seizures, severe vomiting, organ toxicity, and death in some cases (6002,40888). There is insufficient reliable information available about the safety of thuja when used topically.
PREGNANCY: LIKELY UNSAFE
when used orally due to abortifacient activity (12); avoid using.
LACTATION: LIKELY UNSAFE
when used orally due to toxicity (11); avoid using.

Thuja products can contain thujone, which might lower the seizure threshold (1304). Theoretically, this could decrease the effectiveness of anticonvulsants drugs.

Thuja might stimulate immune function (1305). Theoretically, taking thuja might decrease the effects of immunosuppressive therapy. Immunosuppressant drugs include azathioprine (Imuran), basiliximab (Simulect), cyclosporine (Neoral, Sandimmune), daclizumab (Zenapax), muromonab-CD3 (OKT3, Orthoclone OKT3), mycophenolate (CellCept), tacrolimus (FK506, Prograf), sirolimus (Rapamune), prednisone (Deltasone, Orasone), and other corticosteroids (glucocorticoids).

Thuja products can contains significant amounts of thujone, a neurotoxin (1304). Theoretically, patients taking drugs that lower the seizure threshold might be at greater risk of seizure if they also take thuja. Advise patients taking these drugs to avoid thuja products. Some drugs that lower the seizure threshold include anesthetics (propofol, others), antiarrhythmics (mexiletine), antibiotics (amphotericin, penicillin, cephalosporins, imipenem), antidepressants (bupropion, others), antihistamines (cyproheptadine, others), immunosuppressants (cyclosporine), narcotics (fentanyl, others), stimulants (methylphenidate), theophylline, and others.

General ...Orally, large doses of thuja have been reported to cause toxicity involving headache, nervous agitation, seizures, gastric irritation, vomiting, abdominal pain, and diarrhea. Thuja toxicity has also been reported to cause liver damage, renal toxicity, and death in some cases (6002,40888).
Dermatologic
...Contact dermatitis, presenting as an itchy papular squamous eruption on the hands, developed in a 46-year-old female who handled thuja plants while gardening.
It resolved when contact with thuja was avoided. The causative ingredient of thuja was identified as limonene (113415).
In one case report, a 5-year-old female presented with a papillary eccrine adenoma. In an effort to avoid excisional biopsy, an ointment containing thuja was applied to the lesion for 6 months, resulting in peripheral extension and central necrosis of the lesion, eventually necessitating complete excision (106048).
Gastrointestinal ...Orally, large doses of thuja have been reported to cause toxicity involving gastric irritation, vomiting, abdominal pain, and diarrhea (6002,40888).
Hepatic ...Orally, large doses of thuja have been reported to cause toxicity involving liver damage and death (6002,40888). In one case report, a healthy 40-year-old female taking thuja and black cohosh for 1 month presented with 3 days of severe abdominal pain and AST and ALT levels exceeding 5 times the upper limit of normal. Symptoms improved within 5 days of supplement discontinuation and levels normalized within 2 weeks (106047). It is unclear if this reaction was due to thuja, black cohosh, or other factors.
Neurologic/CNS ...Orally, large doses of thuja have been reported to cause toxicity involving nervous agitation, seizures, and death (6002,40888).
Renal ...Orally, large doses of thuja have been reported to cause toxicity involving renal toxicity and death (6002,40888).
