Yarrow Blue

Application Suggestions (See Essential Oil Usage for more information and a Dilution Chart.)

Ragweed allergy? Tisserand states in his Master Safety Class Q&A on Unit 3 that there is "absolutely no connection between using Roman Chamomile or Yarrow essential oils and a ragweed allergy."

Children: For infants and children, please refer to the Dilution Chart on the Babies and Children page. 

Inhalation: Diffuse or use a personal Nasal Inhaler

Internal: Yarrow Blue is suitable for internal use within safe parameters if such use is deemed appropriate. We feel that internal use is rarely *needed* and should only be used with respect for how concentrated the oils are. HEO does not advocate internal use of essential oils without appropriate knowledge and understanding of how to administer, for what purpose, how much, which essential oils, safety concerns and so on. In our experience, essential oils are generally more effective used topically with proper dilution or inhaled. Kurt Schnaubelt, Ph.D. notes that "French aromatherapy literature contains many references to using oils orally." He goes on to note that "generally 1 drop is always enough when ingesting essential oils." A potential toxicity hazard could occur when untrained people use essential oils orally and ingest too much.Keep in mind that while medical doctors or health care practitioners may prescribe essential oils for internal use, they are trained and experienced in the safe application of essential oils. It is not a matter of using "French" or "British" methods, it's a matter of experience and appropriate application. Maximum adult daily oral dose is 8 drops. Click here for information about internal usage.
