Blue Tansy essential oil 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 plant's oil belongs to the same family as chamomile oils, which includes Roman Chamomile and German Chamomile. In this context, it is no surprise that Blue Tansy is sometimes called “Moroccan blue chamomile.”
Chamazulene
What Blue Tansy and German chamomile have 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 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 it can have a powerful calming effect. Remember, however, that with great power also 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 caution.
Myrcene
In addition to its chamazulene content, Blue Tansy oil is 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 impurities on the skin.
Conclusion
Until 2017, Blue Tansy was only offered as an ingredient in Deep Blue® and several other blends. Blue Tansy is an excellent addition to the doTERRA collection of essential oils. Whether you add it to your skincare routine or simply diffuse it for the sweet aroma, this oil is sure to become a favorite.
