  • Dried (1/2oz) or fresh (1oz) herb to 8oz carrier oil Solar method: Jar the herbs and oil and set in warm space for several days to a few weeks Water bath method: Use a double boiler on low heat and steep 30 minutes Crock pot method: Jar the herbs and oil and place in a crock pot with ½ inch of water and steep on the lowest setting for 2 hours
  • Strain through muslin

Things to Consider With Infused Oil: Allergies, Benefits of carrier oil, Benefits of herbs, Shelf life of the carrier oil, Vitamin E to slow rancidity

Diluting for Topical Use

Why Dilute for Topical Use?

  • Allergic response
  • Constitution
  • Medical conditions
  • Medication interactions
  • Skin sensitivity
  • Systemic toxicity

Topical Use Dilution Examples

Generalized dilution ratio

  • Facial application .25-2% Facial creams or oils Lip balm
  • Full body application 1.5-5% Massage Body lotion or oil
  • Acute injury 3-15% Pain Wound care
  • Spot treatments 10-25% or more Localized rash Bites Nail fungus

Examples of Topical Use Products

Things to Consider With Topical UseThe purpose of the product and the type of product should be considered and can guide dilution rates.

Things to Consider With Topical Use

Essential oil contraindications Specific essential oils might require a lower concentration Children, the elderly, and those of lower constitution may need more dilution Frequency of use Duration of Use Less is more
