Sweet or Knotted Marjoram is not an annual, but is usually treated as such. Native to Portugal, it will usually not stand the winter elsewhere, so must be sown every year. The medicinal qualities of the oil extracted from Sweet Marjoram - Oleum majoranae - are similar to that of the Wild Marjoram.
Marjoram tea is delicious, easy to make, and very calming. Bruise fresh leaves or flowers using a mortar and pestle and add to cold water and boil the tea with the leaves in it. Once the tea reaches a boil turn down the heat and let it steep for at least ten minutes. Drink two cups of this tea over the span of two hours for digestive benefits. Add more leaves or flowers for a stronger taste, the general suggestion is about one teaspoon of the herb for each eight ounces of water (236ml). It has a calming, anti-depressive effect.

Take 1-2mls of the tincture three times a day for its anti-inflammatory effects.
