Sweet Marjoram (Origanum Majorana) is well known as a culinary herb cultivated in gardens all over the world. Steam distillation of the herb Origanum Majorana gives this strongly aromatic oil vaguely reminiscent of Nutmeg & Cardamom. Egypt is the prime source for this oil. It is important to differentiate between the various types of Marjoram Thyme & Oregano as their names tend to get very confusing even to experts. Sweet Marjoram Essential Oil makes up only a small proportion of the Marjoram oils produced most of which tend to be Spanish Marjoram. Spanish Marjoram (Oregano) is a completely different species Thymus Masticina & the so-called Wild Marjoram is the common garden herb Origanum Vulgare cultivated all over the world. Did you know?
