Blue Tansy

The science of Blue Tansy

The essential oil of Blue Tansy is obtained from the leaves, flowers and stems of the plant Tanacetum annuum. The name Blue Tansy is actually a misnomer; the plant itself is a yellow-flowered Mediterranean herb native to Morocco. The oil of the plant belongs to the same family as the chamomile oils, which also includes the Roman Chamomile and German chamomile. In this context, it is no surprise that Blue Tansy sometimes called “Moroccan Blue Chamomile”.


What Blue Tansy and German chamomile in common is the presence of a substance called chamazulene. The intense blue color of chamazulene is what gives them their hue. Interestingly, chamazulene is formed during steam distillation, which explains why the oils are blue and the plants they come from are not. A sesquiterpene compound called matricin, which occurs naturally in the aerial parts of the plants, goes through a reaction when it is in the presence of water vapor at high temperatures. The reaction product is chamazulene, a sesquiterpene with a deep blue hue.

Blue Tansy is an oil with a relatively high chamazulene content. This means that it can have a powerful calming effect. Remember, however, that with great power comes great responsibility. There is so much chamazulene in Blue Tansy that the oil can even turn skin and surfaces blue, so the oil must be used with care.


In addition to the chamazulene content, Blue Tansy oil also unique for its sabinene and myrcene content. Sabine is a cyclic monoterpene known for its woody and spicy aroma. Experimental research also shows that it can be soothing and help reduce blemishes on the skin.


Until 2017, Blue Tansy offered only as an ingredient in Deep Blue® and various other blends. Blue Tansy is an excellent addition to the doTERRA collection of essential oils. Whether you add it to your skincare routine or just diffuse it for the sweet aroma, this oil is sure to become a favorite.
