Background

Sweet marjoram is a perennial herb used around the world medicinally and is also grown for its aromatic leaves, which are used in herbal culinary mixtures, such as herbes de Provence and za'atar. The essential oil is noted as having a sweet and spicy aroma.
Sweet marjoram has traditionally been used to relieve muscle spasms, insomnia (inability to sleep), nausea, and headaches. In aromatherapy, marjoram is used to purportedly help calm individuals who have feelings of emotional instability or who are prone to hysteria or irritability. In early research, sweet marjoram has been studied for its effects in relieving symptoms of asthma, eczema, and skin irritation.

In early study, two drops of marjoram oil taken daily increased the maximum voluntary ventilation in asthmatic subjects. Further study is required before conclusions may be drawn.

Essential oils, as a form of aromatherapy, may be effective in alleviating symptoms associated with atopic eczema. Limited available human study showed that massage with essential oils, including marjoram, was not more effective in alleviating childhood atopic eczema than massage without essential oils. More high-quality prolonged studies with sweet marjoram alone are needed.

Tradition / Theory

The below uses are based on tradition, scientific theories, or limited research. They often have not been thoroughly tested in humans, and safety and effectiveness have not always been proven. Some of these conditions are potentially serious, and should be evaluated by a qualified healthcare provider. There may be other proposed uses that are not listed below.

Dosing

Adults (18 years and older)
There is currently no known safe or effective dose for sweet marjoram. For asthma, two drops of marjoram oil (from the seeds) daily for three months has been used along with proper medical treatment. Sweet marjoram has also been used as a poultice on the skin or as a mouthwash.

Safety

The U.S. Food and Drug Administration does not strictly regulate herbs and supplements. There is no guarantee of strength, purity or safety of products, and effects may vary. You should always read product labels. If you have a medical condition, or are taking other drugs, herbs, or supplements, you should speak with a qualified healthcare provider before starting a new therapy. Consult a healthcare provider immediately if you experience side effects.

Interactions

Interactions with Drugs
Marjoram may lower blood sugar levels. Caution is advised when using medications that may also lower blood sugar levels. Patients taking insulin or drugs for diabetes by mouth should be monitored closely by their qualified healthcare professionals, including pharmacists. Medication adjustments may be necessary.
Marjoram may increase the risk of bleeding when taken with drugs that increase the risk of bleeding. Some examples include aspirin, anticoagulants (blood thinners) such as warfarin (Coumadin?) or heparin, antiplatelet drugs such as clopidogrel (Plavix?), and nonsteroidal anti-inflammatory drugs such as ibuprofen (Motrin?, Advil?) or naproxen (Naprosyn?, Aleve?).
Sweet marjoram may also interact with alcohol, antibiotics, anticholinergics, antifungals, anti-cancer drugs, antiprotozoals, antiulcer drugs, cholesterol-lowering drugs, cholinesterase inhibitors, and diuretics.
