Macerated oils are vegetable oils to which other matter, such as herbs, have been added. The base oils commonly used are Olive or Sunflower and the process is quite simple. The verb to macerate comes from Latin macerat- ‘made soft, soaked’. In today's terms it is to make soft by steeping in a liquid. To get the oil-soluble elements, including the volatile molecules, the colour etc from plants that don’t give us EOs. To use herbs and plants we grow in our gardens for use topically or as salad dressings. To help use up any amounts of fixed carriers that may be leftover from ordering in large quantities.

The raw material is picked and chopped up which breaks the plant cells releasing the lipophilic molecules (including essential oil compounds).The drier the raw plant material the better
This material is put into a base fixed carrier oil and into an airtight container. (Kilner jars are ideal for this) Add 5% wheatgerm to help preserve the oil.
This container is then stored in a warm place (traditionally sunny) so windowsills are ideal and frequently stirred for up to three weeks. The sunshine will gently heat the oil and extract many of the plant’s properties.
After about 3 weeks you can then strain off and filter the oil. Then put into a fresh jar and label. The oil-soluble elements from the plant material including colour and essential oil compounds are now in the fixed oil base and have created a ready blended massage oil.
Most macerated oils will last up to 2 years if kept airtight. These oils can be used like any other carrier oil when strained i.e. added to creams or used as bath oils/ applied topically.
