Safety Data & Contraindications For Stay-Away-Blend

This is a blend that is intended to repel insects and mosquitoes. It has also proven to work well on keeping ticks and chiggers away. Read all about our spray here. 

Please weigh the risks of being bitten by insects versus the associated (albeit low) risks of the oils.

None of the statements above are approved by the FDA, and are not meant to diagnose or cure any condition, and this  product is not intended to diagnose, treat, cure, or prevent any disease.  All information provided here is for educational purposes, and is not intended to be used as a substitute for professional medical advice.

As always, we can not recommend the use of any essential oils (orally, inhalation or dermal) for pregnant women or those attempting to conceive; however, we leave it up to each individual to choose what is right for them.  That being said, you again must weigh the risks of mosquito bites (and the associated potential transmission of viruses) against insect repellent use. If in doubt, we would personally choose to use the Lite-Stay-Away-Spray at 2% strength in addition to reducing the amount of exposed skin.

All ingredients with (TS) in their title are found in doTerra’s TerraShield blend.

Citronella essential oil (cymbopogon nardus) – Warnings: Undiluted Citronella oil has been reported to cause contact dermatitis in humans on rare occasion – low risk. There is a caution about ingesting Citronella if taking any drugs metabolized by CYP2B6. The benefits of the anti-carcinogens (over 60% of the oil) outweighs the smaller 0-1.7% risk of methyleugenol.

Catnip  (nepeta cataria) – Warnings: Catnip has diuretic properties and may increase amount and frequency of urination. Women with pelvic inflammatory diseases or are pregnant should not use.

Santalum Paniculatum (Hawaiian Sandalwood)  Not enough information published on this species yet.

Spartium Junceum – Warnings: No known contraindications. Estragole and safrole are carcinogenic if present in sufficient concentration, however they are not high enough to be concerning, since this absolute is expensive and is likely only used in very small amounts.

Rose Damascena (Damask) aka Rose otto – Warnings: No known contraindications. 21mg/day is the recommended maximum for adult ingestion. Maximum dermal usage is suggested at 0.006%, 0.012%, and 0.6% depending on the source.  Limits are due to the level of methyleugenol (carcinogenic) in rose oil. However, the geraniol levels in rose oil may counteract the carcinogens.
