THUJA: Overview, Uses, Side Effects, Precautions, Interactions, Dosing and Reviews

Overview

Thuja is a tree. The leaves and leaf oil have been traditionally used as medicine. Thuja is used as a flavoring agent in foods and beverages and as a fragrance in the manufacturing of cosmetics and soaps.

People use thuja for various conditions, including respiratory tract infections, cold sores (herpes labialis), osteoarthritis, and many others, but there is no good scientific evidence to support these uses.

How does it work ?

Thuja contains chemicals that might affect the immune system. It also contains a chemical called thujone that can cause brain problems.

Interactions ?

Moderate Interaction

Be cautious with this combination

Medications that increase the chance of having a seizure (Seizure threshold lowering drugs) interacts with THUJA
Some medications increase the chance of having a seizure. Taking thuja might cause seizures in some people. Taking medications that increase the chance of having a seizure along with thuja might increase the risk of having a seizure. Do not take thuja with medication that increases the chance of having a seizure.

Some medications that increase the chance of having a seizure include anesthesia (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.
Medications used to prevent seizures (Anticonvulsants) interacts with THUJA
Medications used to prevent seizures affect chemicals in the brain. Thuja may also affect chemicals in the brain. By affecting chemicals in the brain, thuja may decrease the effectiveness of medications used to prevent seizures.

Some medications used to prevent seizures include phenobarbital, primidone (Mysoline), valproic acid (Depakene), gabapentin (Neurontin), carbamazepine (Tegretol), phenytoin (Dilantin), and others.
Medications that decrease the immune system (Immunosuppressants) interacts with THUJA
Thuja can increase the activity of the immune system. Taking thuja along with some medications that decrease the immune system might decrease these medications' effectiveness.

Some medications that decrease the immune system 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).
