Sweet marjoram

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.

These uses have been tested in humans or animals. Safety and effectiveness have not always been proven. Some of these conditions are potentially serious, and should be evaluated by a qualified healthcare provider.
 
Asthma (Grade: C)
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.
Atopic eczema (Grade: C)
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.
Skin irritation (Grade: C)
Based on the use of a topical combination product containing marjoram, marjoram oil may be effective in reducing redness of the skin. Further study is required before conclusions can be drawn.
