The Amazing Power of the Sun to Infuse Herbs

The Power of the Sun

Harness the power of the sun when infusing herbs in oil using the simpler’s method.

Infusing oil with herbs turns the oil into medicinal preparations that can then be used for many things such as medicinal salves, body butter, creams, lotions, soaps, hair serums, massage oil, lip balms, and more.

There are a few methods of infusing oil, but my favorite is to harness the power of the sun to naturally infuse the oil with the goodness and medicinal properties of the herbs. This is often referred to as the simpler’s method and is used by many folk herbalists like myself. This method is based on ratios, where measurements are referred to as “parts”. For instance, 1 part dried herb to 5 parts oil is a very common ratio used in herbal oils.

My favorite topical-infused oil is calendula oil. This golden liquid is wonderfully soothing if you suffer from dry, itchy, or sore skin, and is super gentle, so can even be used by children.  I also love chamomile, rose, and rosemary infused oil.

Preparing Your Herbs


  • You can generally use dried or fresh plant material when available, though some herbs, such as calendula or others with high water content, are better when dried.
  • If using fresh herbs, pick them on a dry day after the sun has dried the morning dew.
  • Only choose plant material from chemical or fertilizer-free areas. This is particularly important because you are not going to wash the plant material, so you want it to be as dry as possible to prevent spoilage.
  • If using fresh herbs, chop them finely and fill the jar loosely to the top.  Cutting them ensures that there will be more reactive with the oil.
  • For dried herbs, roughly chop them and place them in the jar, filling it halfway.
  • Fill the jar almost to the brim with oil. This reduces the amount of air in the jar. Too much air promotes oxidation and spoilage.
  • Stir the contents until all the bubbles have dispersed. Cap your jar and label it with the contents and date. 
  • To really harness the power of the sun, you’ll want to leave it to infuse on a bright, sunny windowsill.
  • Stir every day for the first two weeks then leave to infuse for another two to four weeks, that’s four to six weeks in total. Calendula and some other oils are nice to double infuse—leave for 3 weeks, strain, then fill the jar with fresh flowers and pour the partially infused oil back on top and repeat the process.
  • After 6 weeks, strain your oil through a cheesecloth and discard herbs.
  • Bottle the resulting oil and label and date.

The biggest factor in determining the quality of your homemade herbal oil depends on making sure that no oxidation or spoilage occurs. It is difficult to determine the strength of your herbs therefore it is important to take every precaution to reduce spoilage.

Using the highest quality oils is as just as important as the quality of the herbs used. Many organic carrier oils may be used, but Jojoba oil, Sunflowerand Olive oil are wise choices because they have a long shelf life and are suitable for a variety of applications.

Where to buy high-quality herbs

If you don’t have access to local or homegrown herbs, then I highly recommend Mountain Rose Herbs. They are my favorite place to buy high-quality, organic dried herbs and herbal products.  They’re a wonderful company that believes in people, plants, and the planet over profit.  Definitely my kind of company.
