Blue Tansy

Blue Tansy, Moroccan Tansy Tanacetum annuum

Botanical family: Asteraceae (Compositae)

Other names: Often referred to as ‘Moroccan blue chamomile’ – but it is not a chamomile! Moroccan Chamomile is actually an entirely different species. It must not be confused with Tansy (Tanacetum vulgare) or Blue/German chamomile (Chamomilla recutita).

Description of the plant: Tanacetum annuum produces leaves and flowers, from which the Blue essential oil Tansy Blue is extracted through high pressure, low heat steam extraction.

Historical notes: The genius name, tanacetum, comes from the Greek word ‘Athanasia’ meaning ‘immortality’.

Tansy flowers appear in Greek mythology, but it is the Tanacetum vulgare, a related species, which creates a very different essential oil. According to the myth, Zeus ordered tansy flowers to be added to Ganymede’s drink to immortalize him as a cup-bearer to the gods.

The association with immortality most likely relates to the fact that tansy flowers do not wilt and can be easily dried up.

How we use it: Inhalation / Vaporization:

– Vaporize a couple of drops or use in an aroma inhaler for stress and stress-related issues such as anxiety or insomnia. You can use it on its own or try it blended with lavender, helichrysum, frankincense, bergamot, lemon or sweet marjoram – there are many combinations to try!

– Try in an aroma inhaler for allergy-induced asthma or hay fever.

– For hey-fever try in an aroma inhaler with lavender and a drop of eucalyptus

Skin applications:

– For stress related conditions try it diluted in a fixed oil (carrier oil) with lavender and use in massage or in a bath.

– For inflammatory skin complaints – dilute with some helichrysum and/or lavender in a fixed oil (carrier oil) or unscented organically certified base cream.

Blends well with: Most essential oils, though particularly Ravensara.

Cautions: Tansy Blue is generally non-irritating and non-toxic. Nonetheless, the preferred mode of use is external. It seems to display its strongest effects if its maximum concentration in a blend does not exceed 5%. Some also state that it is contraindicated with an endocrine imbalance in women. It should not be used in pregnancy. As it contains camphor, it is best avoided with epilepsy and children. Use for a limited period.

Safety considerations:

Tisserand and Young warn that blue tansy oil presents hazard (all routes of application) due to its possible drug interaction with drugs metabolized by CYP2D6. Reading Tisserand and Young’s full profile is recommended. [Robert Tisserand and Rodney Young, ‘Essential Oil Safety’ (Second Edition. United Kingdom: Churchill Livingstone Elsevier, 2014), 325-328.]
