How to Make a Cold Infused Oil

A cold infused oil is the process of soaking dried herbs in a carrier oil. An herbal oil infusion extracts all the active fat soluble ingredients from the herb into the carrier oil so you can receive all it's healing benefits. This process does not require any heating, it only requires time and patience.

It's important to note that infused oils are not the same as essential oils. Essential oils are only the plant's volatile oils that are extracted by steam distillation. Similarly, Infused oils are in skin care, hair care, and great for culinary purposes.

How to Make a Cold Infused Oil

Standard Ratio

  • 250g dried herb
  • 3 cups carrier oil – olive oil, almond oil, coconut oil, or any other high quality organic oil.

Step by Step Instructions

  1. First, measure out your herbs and place in a clear glass jar.
  2. Pour oil until it completely covers the herb, close the jar, and shake well. Place the jar in a sunny spot, such as a windowsill, and leave for 4-6 weeks.
  3. After the infusion time is over, pour the oil into a muslin cloth, fine metal strainer, or use an herb press. Allow all of the oil to filter through and press or squeeze the remaining oil from the herbs.
  4. Lastly, pour the infused oil into a dark glass bottle, label ad store.

Cold Infused Oil Tips & Tricks

Seedling Mat

If you are infusing multiple oils and don't have enough window sill space or it's winter and not sunny, use a seedling mat like this one to keep the jar lightly warm and to encourage the infusion.

Use Good Quality Herbs

Foraged herbs are usually the best quality and freshness but not all herbs are found in all areas so its important to buy good quality herbs. An online source for herbs that I like is Starwest Botanicals.

Always Used Dried Herbs

It's best to use dried herbs when infusing oils because fresh plant matter will release moisture into the oil which can cause mold growth. You can air dry fresh herbs by laying them out on a table, using an herb drying rack, or a dehydrator.


Store in a sterilized, airtight, dark glass bottle for up to 1 year, for best results, use within 6 months.

Many of the Holistic Mama handmade products contain infused oils such as Arnica Salve and Coffee Eye Cream.
