Tansy essential oil and blue tansy essential oil are very different in their chemical make-up, and subsequent use, despite the fact that they both belong to the Asteraceae plant family. In addition, blue tansy can also be known by the synonyms Moroccan blue chamomile and Moroccan tansy, adding to further confusion with another essential oil. Here’s a quick look at the difference between these two types of tansy oils.

Profile of Tansy Essential Oil

Tansy (Tanacetum vulgare) is a medium-sized herb that grows up to three feet in height. It has dark-green, fern leaves and small, round, yellow flowers. It has a fragrant aroma. The essential oil is extracted by steam distillation from the aerial parts of the plant.

Use of Tansy in Aromatherapy

Tansy essential oil has a warm, spicy-herbaceous aroma. The principal chemical component in tansy essential oil is thujone, a fairly “reactive” component. Lawless lists tansy as “abortifacient” and advises against use of the essential oil for therapeutic aromatherapy practice.

Profile of Blue Tansy Essential Oil

Blue tansy (Tanacetum annuum) is confusingly also known as blue Moroccan chamomile – not to be confused with Moroccan chamomile (Ormenis multicaulis)*. It owes its other synonym, Moroccan tansy, to its country of origin, Morocco. Blue tansy is an annual herb that produces one of the “blue” essential oils; other “blue” essential oils include German chamomile (Matricaria recutica), yarrow (Achillea millefolium), and Roman chamomile (Chamaemelum nobile). All members of the Asteraceae plant family, the “blue” oils owe their nickname to the azulene chemical component present in the essential oil (from the Spanish word azul, meaning blue).

*NOTE: Schnaubelt lists blue tansy (tanacetum annuum) as Moroccan chamomile in his works. It is important to be familiar with the botanical names of plants for this reason.

Use of Blue Tansy in Aromatherapy

Blue tansy essential oil has a herbaceous aroma. It is extracted from the annual herb (aerial parts) by steam distillation. Rose list the uses of blue tansy essential oil for sciatica, asthma, nerve sedative, and in skincare. Schnaubelt indicates its use for allergies. However, the essential oil is contra-indicated for use with women who have an endocrine imbalance and in pregnancy. In addition, do not use in dilution above 5%.

  1. Ana had this to say about that:

    Can blue tansy be used in epileptics?

    • SharonF had this to say about that:

      Hi Ana!
      You would need to have a consultation with a certified aromatherapist to obtain a definitive answer specific to your health history. It can interact with certain medications. It also depends on dilution rate and how you use it.

  2. Jacklyn had this to say about that:

    Hi there: Just curious which of the references above did you find the info for this statement: However, the essential oil is contra-indicated for use with women who have an endocrine imbalance and in pregnancy. In addition, do not use in dilution above 5%.” I use some products which contain blue tansy and would love to be more educated about it. I could not find the information in the Essential Oil Safety book 2nd ed. (by Tisserand, et al) that I have. Thanks so much!

    • SharonF had this to say about that:

      Hi Jacklyn!
      Thank you for taking the time to read and comment! Jeanne Rose states that blue tansy essential oil “should not be used on certain women with endocrine imbalance.”

      Most essential oils should only be used at about 2% dilution in an aromatherapy blend. 5% is quite high, and I wouldn’t recommend using any essential oil above this level, but particularly more “volatile” essential oils such as blue tansy (check out its chemical components :) ). Tisserand and young also state that it can interact with some drugs (see page 439).

      Hope that helps!
