Tanacetum annuum (Blue Tansy) oil

TAN

5/10

Concern level

Moderate concern

Steam-distilled essential oil from Tanacetum annuum aerial parts/flowering tops. Blue tansy owes its color to chamazulene formed during distillation; it is marketed for calming, anti-redness use, but the ingredient is still an essential oil with meaningful sensitization potential and should be used only at low levels.

Risks & Warnings

Can irritate or sensitize skin, especially in leave-on products or if oxidized. Because it is an essential oil, it should be avoided undiluted and used cautiously in pregnancy and breastfeeding due to limited safety data. Avoid confusing it with common tansy (Tanacetum vulgare), which is more toxic. ([healthline.com](https://www.healthline.com/health/blue-tansy?utm_source=openai))
